Parkinsons disease is characterized by the loss of specific brain cells that make the chemical dopamine. Without dopamine, nerve cells cannot communicate with muscles and people are left with debilitating motor problems. Aspen is focusing on human pluripotent stem cells, cultured cells that can become any cell type in the human body. Many health technology startups are on the raise to cure this disease. At the forefront is Aspen Neuroscience, a healthtech startup developing first-of-its-kind personalized cell therapy for Parkinsons disease.

Aspen Neuroscience is a development stage, private biotechnology company that uses innovative genomic approaches combined with stem cell biology to deliver patient-specific, restorative cell therapies that modify the course of Parkinsons disease.

Today,Aspen Neuroscience announced its official launch with $6.5 million seed financingto develop the first autologous cell therapies for Parkinsons disease.The round was led by Domain Associates and Axon Ventures and including Alexandria Venture Investments, Arch Venture Partners, OrbiMed and others.

Aspens proprietary approach was developed by the companys co-founders, Jeanne F. Loring, Ph.D., Professor Emeritus and founding director of the Center for Regenerative Medicine at The Scripps Research Institute, and Andres Bratt-Leal, Ph.D., a former post-doctoral researcher in Dr. Lorings lab. The company was initially supported by Summit for Stem Cell, a founding partner and non-profit organization which provides a variety of services for people with Parkinsons disease. Aspen is led by industry veteran Howard J. Federoff, M.D., Ph.D., as Chief Executive Officer.

The companys research is specific to induced pluripotent stem cells (iPSCs), which it develops by taking a skin biopsy from a person with Parkinsons disease and turning the tissue into pluripotent stem cells using genetic engineering. Aspen then differentiates the pluripotent stem cells into dopamine-releasing neurons that can be transplanted into that same person (autologous), thereby restoring the types of neurons lost in Parkinsons disease.

As an autologous cell therapy for Parkinsons disease, Aspens treatment would eliminate the need for immunosuppression because the neurons are transplanted back into the same patient from which they were generated. The use of immunosuppression is necessary with currently available cell therapies for Parkinsons disease and when transplanting cells from one patient to another (allogeneic) to prevent rejection but can pre-dispose the patient to life-threatening complications including infection and add cost to the patient and health system. Aspen is the only company in the world offering an autologous neuron replacement therapy for Parkinsons disease.

Aspen encompasses a powerful executive leadership team including Dr. Federoff who, in addition to his leadership roles at the UC Irvine Health System, was the Executive Vice President for Health Sciences and the Executive Dean of Medicine at Georgetown University. Dr. Federoff also has significant biotech industry experience including co-founding MedGenesis Therapeutix and Brain Neurotherapy Bio, as well as leading the U.S. Parkinsons Disease Gene Therapy Study Group. The company is also proud to announce the addition of several experienced and well-known members to its leadership team including Edward Wirth, M.D., Ph.D., as Chief Medical Officer.

Dr. Wirth currently serves as the Chief Medical Ofcer for Lineage Cell Therapeutics where he oversees clinical development of its two therapeutic programs for spinal cord injuries and lung cancer. He received his M.D. and Ph.D. from the University of Florida in 1994 and remained to conduct postdoctoral research including leading the University of Florida team that performed the rst human embryonic spinal cord transplant in the U.S. Dr. Wirth went on to serve as the Medical Director for Regenerative Medicine at Geron Corporation where the worlds rst clinical trial of human embryonic stem cell (hESC)-derived product occurred which demonstrated initial clinical safety.

Drs. Federoff and Wirth are joined by Dr. Loring, as Chief Scientific Officer; Jay Sial, as Chief Financial Officer; Andres Bratt-Leal, Ph.D., as Vice President of Research and Development; Thorsten Gorba, Ph.D., as Senior Director of Manufacturing and Naveen M. Krishnan, M.D., M.Phil., as Senior Director of Corporate Development.

Aspen is developing a restorative, disease modifying autologous neuron therapy for people suffering from Parkinsons disease, said Dr. Federoff. We are fortunate to have such a high-caliber scientific and medical leadership team to make our treatments a reality. Our cell replacement therapy, which originated in the laboratory of Dr. Jeanne Loring and was later supported by Summit for Stem Cell and its President, Ms. Jenifer Raub, has the potential to release dopamine and reconstruct neural networks where no disease-modifying therapies exist.

LentiGlobin, Bluebird Bios investigational gene therapy for sickle cell disease (SCD), continues to show promising results in SCD patients participating in the companys Phase 1/2 HGB-206 clinical trial, according to the latest study data.

The new findings which included data from additional patients treated in the trial, updated data from those previously reported, and exploratory analyses were presented at the 61st American Society of Hematology (ASH) Annual Meeting and Exposition, held Dec. 6-10 in Orlando, Fla.

LentiGlobinisa gene therapy that has been developed to increase the levels of hemoglobin the protein that transports oxygen in the blood in people with SCD.

The therapy works by delivering functional copies of a modified form of the beta-globin gene (A-T87Q-globin gene) into patients red blood cell precursors, known as hematopoietic stem cells, or HSCs. Once these precursors differentiate, their red blood cells start producing a modified version of hemoglobin, called HbAT87Q.

By boosting the production of this anti-sickling form of the protein, LentiGlobin reduces the proportion of defective hemoglobin in patients red blood cells. That, in turn, reduces the sickling and destruction of these red blood cells and other complications associated with SCD.

The safety and efficacy of LentiGlobin is currently being evaluated in three groups identified as A-C of SCD patients participating in Bluebirds ongoing open-label, Phase 1/2 HGB-206 trial (NCT02140554).

Those in group A were treated per the original trial protocol. Meanwhile, those in groups B and C received an enhanced treatment protocol, approved in 2016, that is designed to increase the therapys efficiency. In groups A and B, patients HSCs were extracted from the bone marrow, while in group C, they were extracted from the blood.

As of the data cutoff date of August 26, 2019, seven participants in group A, two in group B, and 17 in group C had been treated with LentiGlobin. According to new data presented at the meeting, only two patients from group A required regular blood transfusions after the treatment.

In addition, the updated findings revealed that the levels of anti-sickling HbAT87Q remained stable in all participants from groups A and B over a post-treatment follow-up period of three years. Similarly, levels of total hemoglobin also were found to have remained stable in both patient groups over a two-year follow-up.

At the trial participants last visit, the median levels of anti-sickling HbAT87Q were 0.9 g/dL among those from group A, and 3.6 g/dL and 7.1 g/dL in the two patients from group B. The median levels of total hemoglobin were 9.0 g/dL among patients from group A, and 11.3 g/dL and 13.0 g/dL among those from group B.

Normal levels of hemoglobin in the blood range from 12.5 to 17.5 g/dL.

Among 12 patients from group C who were followed for at least six months, the median levels of anti-sickling HbAT87Q made up at least 40% of their total hemoglobin. At their last visit, the levels of anti-sickling HbAT87Q ranged from 2.7 to 9.0 g/dL, and the levels of total hemoglobin from 9.3 to 15.2 g/dL.

In groups A and B, LentiGlobin reduced the frequency of painful vaso-occlusive crises (VOCs) and acute chest syndrome (ACS) in the two years following treatment.

Nine patients from group C who were followed for at least six months had experienced four or more VOCs or ACS episodes in the two years prior to receiving LentiGlobin. Treatment with the gene therapy led to a reduction of 99% in the frequency of annual VOCs and ACS. In this group, there were no reports of ACS or severe VOCs for up to 21 months following treatment.

Moreover, among those from group C, LentiGlobin reduced the levels of different markers of red blood cells destruction, including reticulocytes, lactate dehydrogenase (LDH), and bilirubin.

LentiGlobins safety profile was consistent with previous data. No serious adverse events related to treatment were reported during the study. Only one mild, non-serious event of hot flush was found to be related to LentiGlobin. That event was rapidly resolved and did not require treatment.

Exploratory analyses were performed in a sub-group of patients from all three groups. In 12 participants who had been followed for at least six months, more than 70% of the individuals red blood cells were found to contain the anti-sickling HbAT87Q at the last study visit, these analyses showed. Moreover, in four of these patients, nearly all their red blood cells (90%) were positive for HbAT87Q.

In addition, exploratory analyses revealed that participants red blood cells were less prone to sickling following treatment with LentiGlobin.

At ASH, the growing body of data from our clinical studies of LentiGlobin for SCD reflects results from 26 treated patients with up to four years of follow-up, David Davidson, MD, Bluebird Bios chief medical officer, said in a press release.

We continue to observe patients treated in Group C producing high levels of gene-therapy derived anti-sickling hemoglobin, HbAT87Q, accounting for at least 40% of total hemoglobin in those with six or more months of follow-up, and exploratory assays show that HbAT87Q is present in most red blood cells of treated patients, Davidson said.

The robust production of HbAT87Q was associated with substantial reductions of sickle hemoglobin, HbS, as well as improvement in key markers of hemolysis [red blood cells destruction]. Most importantly, patients in Group C have not experienced any episodes of acute chest syndrome or serious vaso-occlusive crises following LentiGlobin for SCD treatment, he added.

The company is recruiting participants with transfusion-dependent -thalassemia (TDT) for a Phase 3 trial (NCT03207009) testing LentiGlobin. Moreover, according to the companys pipeline, there is a Phase 2/3 trial planned in sickle cell disease for this gene therapy.

LentiGlobin Gene Therapy Continues to Show Promising Results in SCD, Updated Trial Data Shows - Sickle Cell Anemia News

Bone Marrow Stem Cells Comments Off on LentiGlobin Gene Therapy Continues to Show Promising Results in SCD, Updated Trial Data Shows – Sickle Cell Anemia News | December 12th, 2019

According to an analysis of interim results from a randomized study of young patients with high- or intermediate risk B-cell precursor acute lymphoblastic leukemia (B-ALL) at first relapse, the overall efficacy and safety of post-reinduction therapy with the bispecific T-cell engager (BiTE) blinatumomab outperformed conventional chemotherapy. The findings from this study were presented at the 61st American Society of Hematology (ASH) Annual Meeting and Exposition held in Orlando, Florida.

Disease relapse, particularly early relapse, following initialtreatment of children, adolescents, and young adults with B-ALL is a marker ofpoor prognosis. While allogeneic hematopoietic stem cell transplantation (HSCT) is typicallyconsidered the treatment of choice for these patients, barriers to itsimplementation can include concerns related to adverse events associated withreinduction and subsequent consolidation chemotherapy, and the presence ofminimal residual disease (MRD) following administration of second-remission reinductiontherapy. Those patients who experienceearly bone marrow relapse, and those with MRD greater than 0.1% in the settingof a prolonged CR, at the end of reinduction therapy are considered to have high-riskand intermediate-risk disease, respectively.

Blinatumomab is an artificial, bispecific monoclonal antibody-basedconstruct created from the fusion of single-chain variable fragments from 2different antibodies. In the case of blinatumomab, targets include the CD3receptor on T cells and CD19 on B cells, resulting in the formation of a link betweenthese 2 cell types.

Currently, blinatumomab is approved by the US Food and DrugAdministration (FDA) for the treatment of adult and pediatric patients with B-ALL in first or second CR,with minimal residual disease (MRD) greater than or equal to 0.1%, as well asfor patients with relapsed/refractory B-ALL.2

In this phase 3 Childrens Oncology Group study (AALL1331; ClinicalTrials.gov Identifier: NCT02101853), patients with B-ALL in first relapse between the ages of 1 and 30 years with bone marrow blasts less than 25% and/or failure to clear extramedullary disease following reinduction chemotherapy (UKALLR3 regimen3) were randomly assigned in a 1:1 ratio following risk assessment to receive either 2 blocks of intensive consolidation chemotherapy according to the UKALLR3 regimen3 or two 4-week cycles of otumumab separated by a 1-week break. Allogeneic HSCT was scheduled following these treatments.

The primary end point of the trial was intent-to-treat disease-freesurvival (DFS), with secondary study end points including MRDresponse, overall survival (OS), and ability to proceed to HSCT.

A planned interimanalysis of 208 patients, performed followingthe occurrence of approximately 60% of expected events,included only those with high- (67%) or intermediate-risk (33%) disease. Patientages ranged from 1 to 27 years, with a median age of 9 years.

At a medianfollow-up of 1.4 years, some of the key efficacy findings from this analysis includedrates of 2-year DFS in the intention-to-treat (ITT) population of 41.0% forpatients receiving chemotherapy and 59.3% for those treated with blinatumomab (P =.050). Rates of 2-year OS forpatients in these 2 study arms were 79.4% (blinatumomab) and 59.2% (chemotherapy),(P =.005).

The percentages ofthose achieving undetectable MRD after reinduction chemotherapy were only 22%and 18% in the chemotherapy and blinatumomab arms, respectively. Followingblock 2 of chemotherapy (ie, first cycle of consolidation chemotherapy) orcycle 1 of blinatumomab, rates of undetectable MRD increased to 29% in thechemotherapy arm and 76% in the blinatumomab arm (P <.0001).

Regarding resultsrelated to MRD response, all of the benefit of blinatumomab with respect to MRDclearance appeared to occur in the first cycle, commented PatrickA. Brown of the Sidney Kimmel ComprehensiveCancer Center, Johns Hopkins University, Baltimore, Maryland, who was thepresenting study author.

Furthermore, 45%of patients in the chemotherapy arm compared with 73% of those in the blinatumomabarm were able to proceed to HSCT (P<.0001).

Regarding patientsafety, 4 and 0 patients receiving blinatumomab or chemotherapy, respectively,experienced a postinduction, induction-related toxic death.

In addition, thefrequencies of specific adverse events were considerably higher in thechemotherapy vs the blinatumomab arm. For example, rates of grade 3 or higher febrileneutropenia were 44% and 46% for patients receiving the 2nd and 3rd blocks ofthe UKALLR3 regimen, respectively, but only 4% and 0% of patients receivingcycle 1 and cycle 2 of blinatumomab, respectively (P <.001). Similar differences between the 2 study arms wereobserved with respect to the rates of infections and sepsis.

For patientsreceiving blinatumomab, low-grade cytokine release syndrome (CRS), occurring in22% of patients, was generally limited to the to the first cycle. Seizuresoccurred in 4% and 0% of patients during cycles 1 and 2, respectively, and the incidenceof mostly low-grade encephalopathy was 14% in cycle 1 and 11% in cycle 2.

Accordingto the results of this scheduled interim analysis, the prespecified monitoring thresholdto the primary end point of DFS was not crossed. However, based on the overallresults of the study, the data monitoring committee recommended permanentclosure of study randomization for patients with high- or intermediate-riskdisease, with those in these risk groups immediately crossed over to theblinatumomab arm.

We believe that blinatumomab constitutes anew standard of care in this setting, concluded Dr Brown.

Ever wonder where those neon yellow, green, blue and pink fish came from? You know, the ones that have all the matching accessories: tanks, decorations, rocks and their own special ultraviolet light? Well, as it turns out, a team ofscientists in Singapore were the first ones to genetically modify fish to glow in such a way.

Genetic editing in small animals and plants has been aroundsince the 1970s, according to Synthego, a company that providesgeneticallyedited stem cells. Starting with plants and bacteria, scientists began to explore the realm of DNA and genetics. As their understanding of the proteins grew, so did their curiosity.

When scientists learned how to modify the genes of small, simple organisms, they began to wonder, "How could this be applied to humans?"

The scientific community is stirring with the emergence of CRISPR DNA,more specifically known as the CRISPR-Cas9 protein.CRISPR stands forClustered Regularly Interspaced Short Palindromic Repeats.CRISPR is a faster, cheaper and more accurate way of editing the genome, according to theNational Institute of Health.By sending in two different pieces of CRISPR DNA,scientists are able to modify genes. To do so, theycutout areas of genes that aren'tperforming how they should be or as they're expected to.

Dr. Sandi Connelly, a principallecturer in the Thomas H. Gosnell School of Life Sciences, explained how DNA works and what the CRISPRCas-9 protein actually does. Connelly compared DNA to a street of houses each person has different foundations that sprout out different and unique homes.

CRISPR is a piece of DNA, and we [scientists] attach to it an enzyme ...it cuts the DNA at a very specific place like a pair of scissors, Connelly said. When we look at CRISPR, typically we look at CRISPR Cas-9."

Whereas CRISPR is the DNA itself, Cas-9 is the enzyme, a specialized protein that splits the DNA.Connelly said that this allows for both the CRISPR DNA and the original DNA to stick together like magnets. However, due to the specificity of this technique, scientists need to know where in the DNA they'relooking.

Using those same enzymes, we can cut [and] place back inthe good gene, Connelly said.

Now, this technique would not be doneby injecting the CRISPR DNA directlyinto a fully grown adult. Instead,scientists would take a sample of a persons bone marrow and alter the genes of those cells. Since bone marrow is responsible for producing red blood cells, the new altered bone marrow will produce cells with the new DNA.

Connelly saidthechangeswouldnot be instantaneous.The human body replaces a majority of its cells within 13 days, soit would take around two weeks for the newly edited gene to be present in the human body.

The ability to now alter genes of morecomplexorganisms brings with it a variety of applications. Plants can be changed to increase nutritional value and pesticidal properties,whereas bacteria can be used to generate hormones and medicines.

Dr. David Holtzman,an adjunct professor in the College of Science, understands how gene editing is used and what it could be used for.

Most people are familiar with it [gene editing] for things like modifying plants ...[but] there is a lot of misunderstanding about gene editing, Holtzman said.

There is a lot of misunderstanding about gene editing.

CRISPR has begun to work its way into at-home kits, where those with some scientificexpertise can genetically modify their own plants to glow or be a different color. This is fairly simple in the world of gene editing as it is changing a simple expressed trait one that isbiologically shown.

Genes decide what traits a person has, but that persons environment and what happens to their body determines how those traits are expressed. As gene editing becomes more and more innovative, Holtzman said that there are limitations to what gene editing can and cannot do.

It turns out most traits are more than one gene, Holtzman said.

Holtzman used hair color as an example. Numerous genes and sections of DNA code for what an individual's hair colorwill be. Itcan behard and time-consuming to find the right area of the DNA to target for modification.

Connelly talked about the idea of changing hair coloras well,but took it a few steps further. Shesuggestedthat we may start wanting to create offspring that all have blonde hair and blue eyes, which realistically we could accomplish. This then opens parents up to the ideas of having all male children or all female children.

In recent years, science has progressed faster than we could have thought.What appeared to be science fiction in the past is inching ever closer to our scientific reality.

The ability to do [new]things happens a lot faster than our understanding of what we are doing, Holtzman said.

Regardless of the potential scientific progress that could be made, Holtzman, Connelly and other members of the scientific community are having conversations about what should be done with this technology. Where should the limits lie, and how far should humans gowith genetic technology?

"Where should the limits lie, and how far should humansgowith genetic technology?"

If our parents changed our genes, they would also be changing the genes of all of our descendants by extension. Did they consent to something like that?

Some might argue, whether we gene edit or not, we dont really have control over what our parents did, Holtzman said. There is the possibility that if we changed [certain genes]then we can change them back.

Reversal isn't a guarantee, though.

Holtzman mentioned ways in which gene editing could greatly improve the quality of life for all humankind, such as curing Alzheimers disease. Connelly brought up how easy it would be to reduce the effects of aging using genetic modification.

The consequences of the choices made nowmay not affect the generation making them. As the movement to improve the genetic composition of the human race pushes forward,plots in sci-finovelsmay no longer be abstract, distant futures. Rather, for better or worse, they could bethe reality we are setting up for generations to come.

DORVAL, QC, Dec. 12, 2019 /CNW/ - Novartis Pharmaceuticals Canada Inc. is pleased to announce that sites in Ontario have been certified in accordance with applicable requirements to treat eligible patients with Kymriah (tisagenlecleucel), the first chimeric antigen receptor T cell (CAR-T) therapy that received regulatory approval in Canada. Patients with relapsed/refractory (r/r) pediatric and young adult B-cell acute lymphoblastic leukemia (ALL) and adult r/r diffuse large B-cell lymphoma (DLBCL) may be eligible to be treated with Kymriah at one of the initially certified Canadian treatment sites. This news follows the recent decision by the Ontario government to fund Kymriah and publication of guidelines by Cancer Care Ontario regarding the enrolment process and criteria for patients to receive CAR-T cell therapy.ii

"Early results show that patients who receive CAR-T cell therapy are either seeing their cancer go into remission or can use CAR-T as a bridge to a stem cell transplant," said Christine Elliott, Deputy Premier and Minister of Health. "We are pleased that Ontario is among the first provinces in Canada to offer CAR-T cell therapy to eligible pediatric and adult patients."

Per the guidelines, eligible patients are now able to access Kymriah from The Hospital for Sick Children (SickKids) in Toronto and Hamilton Health Sciences. Princess Margaret Cancer Centre in Toronto and The Ottawa Hospital are working to complete the process to become certified treatment sites and join the network of qualified Ontario centres in 2020.

"Novartis would like to acknowledge and applaud the collaboration of all stakeholders involved, including Cancer Care Ontario, in helping to ensure patients have access to the first CAR-T therapy approved in Canada for patients with B-cell ALL and DLBCL who historically have poor outcomes. Having treatment sites certified in Ontario allows eligible patients to be treated with CAR-T therapy and is in line with our mission to provide rapid access to life-changing therapies to all Canadians," said Christian Macher, Country President & General Manager, Oncology, Novartis Pharmaceuticals Canada Inc. "Novartis is committed to bringing additional qualified Canadian treatment centres into the network to give patients the opportunity to be treated closer to home."

Due to the sophisticated and individualized nature of Kymriah, treatment sites that are part of the network are required to be FACT-accredited (Foundation for the Accreditation of Cellular Therapy). This means they are qualified to perform intravenous infusion of stem cells collected from the bone marrow of a donor, also referred to as allogeneic hematopoietic stem cell transplantation (alloSCT) and have experience with cell therapies and treating leukemia and lymphoma to facilitate safe and seamless delivery of Kymriah to eligible patients.

About KymriahKymriah (tisagenlecleucel), a CD19-directed genetically modified autologous T-cell immunocellular therapy, is approved to treat two life-threatening cancers that have limited treatment options and historically poor outcomes, demonstrating the critical need for new therapies for these patients.

Kymriah is approved by Health Canada for use in pediatric and young adult patients 3 to 25 years of age with B-cell acute lymphoblastic leukemia (ALL) who are refractory, have relapsed after allogenic stem cell transplant (SCT) or are otherwise ineligible for SCT, or have experienced second or later relapse; and for the treatment of adult patients with relapsed or refractory (r/r) large B-cell lymphoma after two or more lines of systemic therapy including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, high grade B-cell lymphoma and DLBCL arising from follicular lymphomai.

Kymriah is a one-time treatment that uses a patient's own T cells to fight and kill cancer cells. Bringing this innovative therapy to Canadian patients requires collaboration among many health system stakeholders.

iPS cells may help halt failing vision

Getty

By Andy Coghlan

A woman in her 80s has become the first person to be successfully treated with induced pluripotent stem (iPS) cells. A slither of laboratory-made retinal cells has protected her eyesight, fighting her age-related macular degeneration a common form of progressive blindness.

Such stem cells can be coaxed to form many other types of cell. Unlike other types of stem cell, such as those found in an embryo, can be made from adult non-stem cells a discovery that in 2012.

Now, more than a decade after they were created, these stem cells have helped someone. at the RIKEN Laboratory for Retinal Regeneration in Kobe, Japan, and her team took skin cells from the woman and turned them into iPS cells. They then encouraged these to form retinal pigment epithelial cells, which are important for supporting and nourishing the retina cells that capture light for vision.

The researchers made a slither of cells measuring just 1 by 3 millimetres. Before in 2014, they first removed diseased tissue on her retina that was gradually destroying her sight. They then inserted the small patch of cells they had created, hoping they would become a part of her eye and stop her eyesight from degenerating.

Now the results are in. Published today, they show that the treatment hasnt made the womans vision any sharper, but it does seem to have prevented further deterioration with her vision now stable for more than two years. Since the graft, the woman says her vision is brighter.

Takahashi and her team have done incredible work, and deserve all the praise they get for this project, says , director of the Center for iPS Cell Research and Application at Kyoto University, who won the Nobel prize for and collaborated on this work. This is a landmark study and opens the door to similar treatments for many diseases, he says.

This first iPSC-derived retinal graft is an important landmark in the field of retinal regeneration, says at University College London, and head of a trial at Moorfields Eye Hospital in London of similar grafts made instead from human embryonic stem cells.

One worry about this approach is that turning the stem cells into new tissues could lead to cancer-causing genetic mutations though the team found no evidence of this in the treated woman. However, a trial of the technique in another person was cancelled in 2015, after tests revealed that the cells intended to be given to the man had developed genetic abnormalities.

But although it has taken many years to bring , many private centres around the world have been advertising unregulated treatments purporting to use stem cells for some time.

A second study published today shows just how badly some unregulated treatments described as stem cell therapies can go wrong. Three case reports of women given such treatments for age-related macular degeneration detail how one woman went blind and the vision of the other two became much worse.

All three ended up seeking emergency treatment in 2015, after each paid $5000 to a private clinic to receive injections of their own fatty tissue into their eyes.

Patients and physicians in the US should be made aware that not all stem cell clinics are safe, and that stem therapy as provided in private clinics in the US is unproven and potentially harmful, says at the University of Miamis Bascom Palmer Eye Institute, Florida, who subsequently treated two of the women.

Albini advises people to be suspicious of any procedure involving payment. Most legitimate research in the US does not require patients to pay for the experimental procedures, he says, adding that people should check whether a trial has been registered with the US Food and Drug Administration. Be aware that if it sounds too good to be true, it may indeed not be true.

Vision saved by first induced pluripotent stem cell treatment - Stock Daily Dish

IPS Cell Therapy Comments Off on Vision saved by first induced pluripotent stem cell treatment – Stock Daily Dish | December 12th, 2019

The idea of a cell therapy for Parkinsons disease starts out simple: Symptoms of the progressive disease are largely driven by the deaths of dopamine-producing neurons found deep within the brain. With lower levels of the neurotransmitter come the characteristic tremors, rigidity and slow movements.

By replacing those lost nerve cells with new dopamine producers, researchers hope to renew the brains connection to the bodys muscles and improve a persons overall motor function.

But in the brain, everything becomes more complicated. On top of the risk of immune system rejection that comes with any kind of living tissue transplant, its important to make sure the implanted cells function correctly and do not pick up any dangerous genetic mutations as they grow.

First, the startup hopes to avoid any harmful immune reactions by using a patients own cells as a starting point. Then, Aspen plans to implement a rigorous quality control program employing whole genome sequencing and artificial intelligence to make sure the cells stay in line as theyre processed and readied for the procedure.

And to do it, the San Diego-based company is starting out with $6.5 million in seed money plus an impressive roster of names.

They are led by neurology researcher Howard Federoff, previously vice chancellor for health affairs and CEO of the University of California, Irvine health system as well as the executive dean of medicine at Georgetown University. Hes joined by Aspen co-founder and stem cell scientist Jeanne Loring, founding director and professor emeritus of the Center for Regenerative Medicine at the Scripps Research Institute.

Meanwhile, the seed round was led by Domain Associates and Axon Ventures with additional backing from Alexandria Venture Investments, Arch Venture Partners, OrbiMed and Section 32.

Aspen looks to combine its expertise in stem cell biology, genomics and neurology to offer the first autologous cell therapy for Parkinsons diseasewhile others in the space have pursued allogeneic routes, or therapies derived from donors other than the patient.

The process starts with a culture of the patients skin cells, which are then genetically induced to become pluripotent stem cellsor cells capable of differentiating into any other cell type in the body. These are then chemically nudged further to transform into precursor versions of the dopamine-producing neurons, which are typically found in the midbrain and regions responsible for the movement of limbs.

We can say without any equivocation that we can produce the population of cells necessary to transplant, and in a short enough period of time to have a potential beneficial impact on the evolution of the disease, said Federoff, who has also served as chair of the NIHs Recombinant DNA Advisory Committee and helped lead the U.S. Parkinsons Disease Gene Therapy Study Group.

We envisage that this will set back the clock on patients who have Parkinsons, unlike any other therapy that we know of, he told FierceMedTech in an interview.

The number of cells needed would be much smaller compared to other cell therapies and cancer treatments. The healthy human brain contains only about 200,000 dopamine-producing nerve cells, split between its two hemispheres, while patients with Parkinsons disease have lost about 50% or more of those neurons.

Aspen aims to evaluate two doses: one that aims to replace about 60% to 65% of a persons normal cell complement and another larger treatment, Federoff said.

Those smaller doses, as well as starting with a patients donor cells, help make the treatment safer to produce by requiring fewer steps. Each cycle of cell division and multiplication to increase their numbers carries the risk of introducing genetic mutations.

As the cells are grown, they are consistently evaluated with data-driven techniques pioneered by Lorings laboratory. Using whole genome RNA sequencing, Aspen will match the cells up at every stage with a genetic barcode taken from each patient at the start. This will allow them to look for changes, duplications or deletions in the pluripotent stem cell genome.

If the cells harbor mutations that are cancer drivers, we don't want to put those into people, Loring said. The only way is to check the sequencing before we transplant them.

The cells used in the transplant procedure arent fully grown; as neuron progenitors, they mimic the development steps seen in the brain of a growing fetus after theyre placed in the body as they wire themselves up to other neural structures and begin to form new networks of their own.

We anticipate that they will manufacture and release dopamine in a manner that is consistent with synaptic neurotransmission and the process of communicating from cell-to-cell, said Federoff. They will take up dopamine from synapses when it has done its business, bring it back into the cell, and prepare it for another synaptic release.

These are not just dopamine pumps, theyre real neurons, added Loring. They will genuinely replace the cells that have been lost in every way.

Aspen plans to pursue two courses of therapy, for the two major types of Parkinsons disease. Their lead candidate is for idiopathic, or sporadic Parkinsons, while their second is a CRISPR-edited version of the therapy designed to address one of the diseases most common genetic mutations, linked to about 5% of cases.

This would not only aim to restart dopamine production in this orphan indication, but also restore the damaged enzyme GBA, which is seen as an underlying cause. Federoff and Loring expect their sequencing-based quality check system will also help catch any off-target edits linked to the use of CRISPR-Cas9.

The company has yet to secure permission from the FDA to officially launch clinical trials, but the agency has signed off on Aspens plans to prepare a trial-ready cohort of Parkinsons disease patients in the meantime. This would include the initial stages of recruitment and testing, including the selection of patients capable of having their skin cells made into pluripotent stem cells.

After it receives its go-ahead from the FDA, Aspen plans to hit the ground running,enrolling at least 176 participants in a phase 1/2 study that includes a randomized stage to determine clinical benefits.

A Campus meeting in November reviewed the arguments for and against donor conception, and the sometimes difficult ethical arguments raised by the prospect of a donor-conceived child. 'Artificial' sperm cells derived from testicular tissue or stem cells may resolve some of those arguments.

The problem is especially acute in cancers diagnosed in prepubertal boys in whom there are no sperm cells available for storage. Their only option for future fatherhood in the face of cancer treatment is adoption or donor sperm. And this, added Goossens, is not an exceptional problem. Incidence rates are around 17 cases per 100,000 population, with leukemia and CNS tumours the most commonly diagnosed. So the usual pathway to fertility preservation in these young cases is for the oncologist to warn of the risk to future fertility from the cancer treatments and refer to the fertility clinic. Biopsy of testicular tissue, of course, must be performed before any radio- or chemotherapy.

Goossens described two experimental techniques, spermatogonial stem cell retrieval and transplantation, and homotopic tissue grafting. The danger in the former procedure is a risk of introducing malignancy, so banked tissue must be free of malignant contamination. Experiments in mouse-to-mouse models have demonstrated spermatogenesis from tissue grafting, and most recently fully functional conception and delivery in a non-human primate (Grady). Similarly, experiments in mouse models with spermatogonial stem cell transplantation have so far proved efficient, with spontaneous pregnancy already possible.

Of course, the objective of this impressive experimental work is not merely a resolution to the question of genetic continuity in couples faced with third-party donation, but the future fertility and long-term quality of life of so many unfortunate young boys. Advances in cancer treatment have led to the increased survival of all children with cancer, and with it a new imperative for the restoration of their fertility. Not all cancer treatments cause complete testicular damage, but around one-third of children having treatment for pediatric cancers will end up infertile. Following the proof-of-concept study which saw the birth of Grady - in which testicular samples removed from prepubertal monkeys was frozen, thawed and regrafted under scrotal skin - the research group declared that their next logical step, with safety and feasibility apparent, is human trials.

KRAS mutations occur in approximately 20% of people with non-small cell lung cancer, and some previous studies have suggested that these mutations are associated with a poorer response to treatment, said Dr. Jonathan Cheng, vice president, oncology clinical research, Merck Research Laboratories. It was therefore encouraging to see in this exploratory analysis that KEYTRUDA monotherapy was associated with a survival benefit in certain patients with metastatic nonsquamous non-small cell lung cancer, regardless of KRAS mutational status.

The objective of the exploratory analysis was to assess the prevalence of KRAS mutations and their association with efficacy in the KEYNOTE-042 trial. Of the 1,274 untreated patients with metastatic nonsquamous NSCLC whose tumors expressed PD-L1 (TPS 1%) enrolled in KEYNOTE-042, 301 patients had KRAS evaluable data (n=232 without any KRAS mutation; n=69 with any KRAS mutation, including n=29 with the KRAS G12C mutation). Tissue tumor mutational burden (tTMB) and KRAS mutational status were determined by whole-exome sequencing (WES) of tumor tissue and matched normal DNA (blood). Patients were randomized 1:1 to receive KEYTRUDA 200 mg intravenously every three weeks (Q3W) (n=637) or investigators choice of chemotherapy (pemetrexed or paclitaxel) (n=637). Treatment continued until progression of disease or unacceptable toxicity. The primary endpoint was OS with a TPS of 50%, 20% and 1%, which were assessed sequentially. The secondary endpoints were PFS and ORR.

Findings from this exploratory analysis showed that KEYTRUDA monotherapy was associated with improved clinical outcomes, regardless of KRAS mutational status, in patients with metastatic nonsquamous NSCLC versus chemotherapy. In this analysis, KEYTRUDA reduced the risk of death by 58% (HR=0.42 [95% CI, 0.22-0.81]) in patients with any KRAS mutation and by 72% (HR=0.28 [95% CI, 0.09-0.86]) in patients with the KRAS G12C mutation compared to chemotherapy. The safety profile of KEYTRUDA was consistent with what has been seen in previously reported studies among patients with metastatic NSCLC.

Additional efficacy results from this exploratory analysis showed:

About Lung Cancer

Lung cancer, which forms in the tissues of the lungs, usually within cells lining the air passages, is the leading cause of cancer death worldwide. Each year, more people die of lung cancer than die of colon and breast cancers combined. The two main types of lung cancer are non-small cell and small cell. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for about 85% of all cases. Small cell lung cancer (SCLC) accounts for about 10 to 15% of all lung cancers. Lung cancer can also be characterized by the presence of different biomarkers, including PD-L1, KRAS, ALK, EGFR and ROS1. KRAS mutations occur in about 20% of NSCLC cases. Between 2008 and 2014, the five-year survival rate for patients diagnosed in the U.S. with advanced NSCLC was only 5%.

About KEYTRUDA (pembrolizumab) Injection, 100mg

KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the bodys immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industrys largest immuno-oncology clinical research program. There are currently more than 1,000 trials studying KEYTRUDA across a wide variety of cancers and treatment settings.

The good news is that dryskin can be easily avoided, and the most efficient way to hydrate parched skin is with a hydrating sheet mask. All it takes is 15 to 20 minutes and youre on your way to plumped, glowing skin.

These days, hydration sheet masks are loaded with so much extra goodness vitamins, minerals, amino acids,organic acids, plant stem cells andpeptidesthat gointo the formulas that these can also help fight wrinkles, eliminate dark spots and lighten skin tone.

CHARLOTTE TILBURY INSTANT MAGIC FACIAL DRY SHEET MASK, S$76

Yes, this is a dry mask that you can get at Sephora. The magic all comes from the warmth of your skin: The bio-mimetic vector delivery system turns a combo of ingredients (crocus bulb extract, plant stem cells, peptides and vitamin B3) from solid to liquid.

Wear the dry mask by looping the hoops over each ear then simply activate the formula by massaging upwards to move the mask into place. After 15 minutes, take it off then gently tap the remaining essence into the skin. Youll soon notice a glow that is similar to the one you get after a super shiok facial.

But dont throw away the mask just yet the dry formula is engineered for reuse. In fact, you can use it three more times. Just slip it back (the formula side facing inward) into the resealable foil pouch for when you need it next. So really, thats four masks for the price of one.

UTENA PURESA SHEET MASK HYALURONIC ACID 5S, S$12.90

You can pick this up at Watsons. There are five masks to a pack and each one combines the benefits of hyaluronic acid and royal jelly extract, infused with a gel-like essence that works to hydrate skin like a jelly mask. To make the most of it, first smoothen the jelly bits onto the face before placing the sheet over the face.

But theres more: Peek into the packaging and youll see lots of jelly bits left. Apply these remaining bits anywhere else you want to hydrate. We personally like to spread it over the neck, the back of the palms and even the elbows. Yes, it also works as a body hydration gel.

SK II FACIAL TREATMENT MASK, S$127

Love SK IIs Facial Treatment Essence? Then youll love this sheet mask because its drenched with so much Facial Treatment Essence that it feels as if youve dunked your face into a tub of Pitera.

It contains 50 micro-nutrients like vitamins, minerals, amino acids and organic acids to condition skin's natural functions. Twenty minutes is all it takes to rehydrate, clarify complexion and have crystal clear skin.

LA MER THE TREATMENT LOTION HYDRATING MASK, S$45

Each sheet mask is infused with a full ounce of La Mers liquid energy skin hydrator and its equipped with Japanese skin-hugging technology that delivers a concentrated surge of healing hydration directly onto the skin to nourish and soften fine lines.

STARSKIN RED CARPET READY HYDRATING BIO-CELLULOSE SECOND SKIN FACE MASK, S$18

Another mask you can pick up at Sephora is one with a difference. Instead of prepping your face, you prep the mask massage the still-closed sachet to distribute the serum liquid evenly before opening.

The exclusive Bio Cellulose sheet a thin biodegradable microfibre is infused with a delicious cocktail of coconut juice, Amino acids and brown algae that work together to strengthen the skin barrier and promote moisture retention. Dull and dehydrated skin doesnt stand a chance.

Materials science company W. L. Gore & Associates Inc. (Newark, DE) has announced a joint venture with the Mayo Clinic (Rochester, MN) to further develop a therapeutic system using stem cells and bio-absorbable scaffolds to treat a condition affecting patients with Crohns disease. Avobis Bio, based in Delaware, will draw on the expertise of scientists and medical professionals from both organizations to build on the encouraging results of an investigational treatment for perianal fistulas.

A debilitating condition that affects patients with Crohns disease, perianal fistulas are painful tunneling wounds connecting the anus to the skin, explained Gore in a press release. Few healing options exist, and patients endure multiple surgeries and ongoing risk of life-threatening complications, said Gore.

"Perianal fistulas are truly life-altering for Crohn's patients, and treatment options have eluded gastroenterologists and surgeons for years," added William Faubion Jr., MD, a Mayo Clinic gastroenterologist who specializes in inflammatory bowel diseases.

The innovative treatment involves harvesting a patients own mesenchymal stem cells, which then are populated on Gore's bioabsorbable polymer scaffold and surgically implanted in the fistula. A phase I clinical trial showed that 76% of patients healed within a year. If this outcome is validated in a larger trial, Gore said that it would dramatically exceed outcomes achieved with existing treatments.

This project is the initial focus of Avobis Bio, which describes its overall mission as an exploration of the use of mesenchymal stem cells combined with enabling bioabsorbable scaffolds that enhance the effectiveness of the cells in stimulating the body to heal.

Delivering a patients mesenchymal stem cells on a synthetic scaffold that biodegrades over time may be a first-of-its-kind medical therapy, noted Joe Carlson, a reporter at the Minneapolis-based Star Tribune reporting on the joint venture. If successful, Avobis Bio may one day offer a variety of tissue and organ-repair therapies combining Mayo's stem cell expertise and Gore's medical materials, he wrote.

Gore is perhaps best known to the public for its Gore-Tex outerwear, but the privately held $3.7 billion engineering and manufacturing firm sells products in an array of industries, including a line of medical devices designed to repair nonnatural holes in body organs, added Carlson. Mayo has used Gore-made devices for many years.

This article highlights some of the most recent drug target discoveries that could be used to develop and design a treatment for pancreatic cancer.

Scientists investigating pancreatic cancer have identified new targets which, with further research, could be the basis for developing future therapies. Listed below are five of the most recent target discoveries, in order of their journal publication dates, with the newest first.

Scientists at the Queen Mary University of London, UK and Zhengzhou University, China have developed a personalised vaccine system that may be able to delay the onset of pancreatic cancer.

Cells taken from mice, mutated chemically into pancreatic cancer cells and then infected with Adenovirus (AdV) as a prime or Vaccinia virus (VV) as a boost, create a vaccine product. The virus kills the cancerous cells in such a way that their antigens are released and are therefore able to prime the immune system to prevent pancreatic cancer returning.

Injection of the virus-infected cells into mice destined to develop pancreatic cancer doubled their survival rate, compared to their unvaccinated counterparts. The vaccine also delayed the onset of the condition in these mice.

Using cells from the recipient of the vaccine enables the immune system to respond to the exact antigens seen in tumour cells of the individual, resulting in a vaccine regime tailored to them.

Through this international collaboration, we have made progress towards the development of a prophylactic cancer vaccine against pancreatic cancer, said Professor Yaohe Wang, leader of the study, from Queen Mary University of London and the Sino-British Research Centre at Zhengzhou University in China.

Researchers at Sanford Burnham Prebys Medical Discovery Institute in the US have identified that a combination of two anti-cancer compounds, already approved for use to treat other cancers, shrank pancreatic tumours in mice.

Our study identifies a potential treatment combination that can immediately be tested against these aggressive tumours. We are already meeting with oncologists at Oregon Health & Science University, US to discuss how to advance this discovery into clinical evaluation, explained Dr Zeev Ronai, a professor in Sanford Burnham Prebys Tumor Initiation and Maintenance Program, also senior author of the study.

Scientists used L-asparaginase to starve pancreatic tumours of asparagine, an amino acid required by cells for protein synthesis. However, the tumour cells did not die, instead switching on a stress response pathway whereby they could produce asparagine themselves. Scientists then used an MEK inhibitor to block the stress response pathway, causing the pancreatic tumour to shrink.

L-asparaginase is already US Food and Drug Administration (FDA) approved to treat leukaemias and similarly the MEK inhibitor is approved for the treatment of solid tumours, including melanoma skin cancer.

This research lays the basis for the inhibition of pancreatic tumour growth by a combined synergistic attack based on asparagine restriction and MAPK signalling inhibition, says Dr Eytan Ruppin, chief of the Cancer Data Science Library at the National Cancer Institute (NCI) and co-author of the study.

Scientists from the Max Planck Institute for Biology of Ageing, Germany have identified that YME1L, a protease in the membrane of mitochondria, is activated when a cell uses glycolysis to produce energy anaerobically.

scientists were able to reduce tumour growth by switching off the glycolysis signalling pathway in the mitochondria

Cells adapt to oxygen deficiency by switching their energy supply to glycolysis, which ferments sugar without oxygen. This switch is often necessary in old age, as the cells in the body become poorly supplied with oxygen and nutrients.

Cancer cells can also face this problem; prior to angiogenesis, tumours are poorly perfused and so the tissue is deprived of oxygen. Oxidative stress in tumours drives the switch-on of multiple pathways. This includes the glycolysis pathway that alters the behaviour of the mitochondria to provide tumour cells with energy despite being starved of oxygen.

Scientists found that the YME1L protease is activated during the conversion to glycolysis. YME1L appears altered and breaks down various proteins in the organelles, preventing the formation of new mitochondria and causing the remaining organelles to change their metabolism. This process eventually stops as YME1L begins to degrade itself at high activity.

Researchers examined cancer cells originating from patients with pancreatic tumours and were able to reduce tumour growth by switching off the glycolysis signalling pathway in the mitochondria, with reproducible results both in the petri dish and in pancreatic tumours in mice.

There is currently no treatment available for pancreatic cancer. I believe that this protease can be a very interesting therapeutic target because we have seen that the signalling pathway is also active in human patients with pancreatic cancer, explained Thomas Langer, the Max Planck Director, continuing: However, there are no known substances that have an effect on this protease.

Researchers at the Crick Institute have identified cancer stem cells as a driver of pancreatic cancer growth. These cells can metastasise and differentiate into different tumour types to continue the spread of cancer.

Cancer stem cells appear at all stages of cancer growth so being able to identify where they are present could be vital in both targeting cancer and developing new treatments, according to the researchers. Analysis of gene expression in the cancer stem cells identified a protein, CD9, is present on tumour surfaces during development and when it is more established. This protein could therefore be used as a marker to help locate these cells.

A further development of the study established that this protein is not just a marker of cancer stem cells, but also promotes their malignant behaviour. By altering the amount of CD9 in tumour cells in mice, researchers found that reduced levels of this protein caused smaller tumours to form and increasing levels of CD9 created more aggressive cells able to form large tumours quickly.

These cells are vital to pancreatic cancer and if even just a few of them survive chemotherapy, the cancer is able to bounce back. We need to find effective ways to remove these cells and so stop them from fuelling cancer growth. However, we need more experiments to validate the importance of CD9 in human pancreatic cancer, says Victoria Wang, lead author and member of the Adult Stem Cell Laboratory at the Crick Institute.

A look into cancer stem cell metabolism also revealed CD9 increases the rate tumour cells take up glutamine, an amino acid which helps provide energy for cancer growth.

Now we know this protein is both linked to cancer stem cells and helps cancer growth, this could guide the development of new treatments that are targeted at the protein and so cut off the supply of glutamine to cancer stem cells, effectively starving the cancer, says Axel Behrens, corresponding author and group leader in the Adult Stem Cell Laboratory at the Crick Institute.

Scientists at Tel Aviv University, Israel have found that PJ34, a small molecule, causes human pancreatic cancer cells to self-destruct. The researchers tested PJ34 on xenografts (transplants) of human pancreatic tumours in mice.

this mechanism also exists in other types of cancer and therefore the treatment could be valuable for use on those resistant to current therapies

The mice were treated with a molecule called PJ34, which is permeable in the cell membrane but affects human cancer cells exclusively. This molecule causes an anomaly during the duplication of human cancer cells, provoking their rapid cell death. Thus, cell multiplication itself resulted in cell death in the treated cancer cells, explains Professor Malca Cohen-Armon, project lead at Tel Aviv Universitys Sackler Faculty of Medicine.

The treatment consisted of daily PJ34 injections for 14 days and four weeks later there was a relative drop of 90 percent in the number of cancer cells within the tumours of the mice. Cohen-Armon also noted there were no adverse side-effects observed in the mice.

This mechanism similarly exists in other types of cancer and therefore the treatment could be valuable for use on those resistant to current therapies. The molecule PJ34 is being tested in pre-clinical trials according to FDA regulations before clinical trials begin.

Five recent drug target discoveries for pancreatic cancer - Drug Target Review

Skin Stem Cells Comments Off on Five recent drug target discoveries for pancreatic cancer – Drug Target Review | December 12th, 2019

Im hairythats just fact, and its something Ive always been aware of. Ill never forget being in summer camp as a kid, wearing shorts every day and becoming very aware that my legs were much hairier than those of the girls around me. Now, Im no longer ashamed of being hairyIve actually come to embrace it. But in the past two decades, Ive gotten very acquainted with epilators, including laser hair removal.

I got my first laser hair removal treatment two years ago. It seemed like everyone was getting it done, but as a black woman, I knew I wasnt everyone. For brown skin, laser hair removal isnt a spur-of-the-moment decision, a process that should be approached through a Groupon or the local nail salon (yes, some nail salons actually perform laser hair removal). For us, the process can be a bit more expensive and tedious, and should be approached with the utmost caution.

Why? Well, lasers target pigment, and due to the high content of melanin in our skin, risks of discoloration and hyper-pigmentation are astronomically higher. So thats why, according to Chris Karavolas, owner of Romeo And Juliette Laser Hair Removal, darker skin requires a completely different laser all together, and operators with much more experience. Darker skin complexions need to be careful because not all centers have the right lasers for dark skin, and even if they do they do, many do not have enough experience in treating dark skin, he says.

When it comes to those specialized lasers, there are two options. Its important to treat with an Nd:YAG laser, such as the Candela GentleYAG or GentleMax Pro, says Anne Chapas, M.D., medical director of Union Square Laser Dermatology in New York City. The wavelength of a YAG laser goes deeper into the skin than a diode laser and is less absorbed by the surrounding skin pigment, so it more successfully treats the stem cells of the hair follicle. Additionally, more treatments may be required than for fairer skin: Expect to receive at least six sessions, Chapas says.

Knowing all these things, I went into laser hair removal with cautious optimism. I chose to treat my Brazilian areayears of improper hair removal had left me with ingrown and severe discoloration, to the point that my wax lady refused to continue treating me because my skin had gotten so irritated. I was sure that I wanted to continue being hair-free down there, so I decided to get laser hair removal on my vagina area. I was nervous heading into my first appointment, so I made sure to ask the aesthetician at Romeo & Juliette in-depth questions about her experience with dark skin, as well as requesting to see photos of previous clients and inquiring about a patch test. Then, it was showtime.

I like to think that I have a pretty high pain tolerance. However, laser removal certainly made me question that belief. I wont lie and say that it didnt hurt. It did. It felt like being snapped, hard, by rubber bands, but it was quick, and the results I saw were almost immediate. I was advised to shave right before the treatment, in order to give the laser immediate access to the hair follicle, and because, well, nobody likes the smell of burning hair. After about 10 minutes, I was sent on my way and advised to come back in another six weeks. Laser hair removal requires a strict schedule and works in conjunction with the hair cycle for optimal results. Every appointment thereafter was just as easy, and now, completely through all six of my sessions, my hair is almost completely gone, with the occasional stubble appearing here and there.

So how do you know if your skin will need one of these specialized lasers? Different ethnicitiesregardless of skin tonereact differently to lasers. Your skin may appear to be a 3 or 4 on the Fitzpatrick scale, but if youre, say, Latin or Asian, it could react to the laser as a 6 would, Dr. Chapas says. So be sure that youre only going to facilities that have operators trained in dermatology, and are skilled enough to differentiate your skin tone.

When embryonic Stem Cell therapy was first discovered in 1998, it changed the face of medicine. The idea of being able to regenerate and replace damaged cells seemed futuristic at the time, yet today such treatments are commonplace. Now, science has taken another quantum leap this time into the nano-sized world of exosomes, tiny bubbles that grow out of cell walls and contain much of the information contained within the cell including Growth factors, microRNA and messenger RNA. Mesenchymal stem cell (MSC) exosome therapy is currently one of the hottest trends in regenerative medicine, one that patients at AM Medical in Yelm can now experience.

Everyone has heard of stem cell therapy, but it turns out that its not the stem cells that are doing the work, says Dr. Ana Mihalcea, President of AM Medical. Its the exosomes that carry the information of regeneration. Infused stem cells, attach to blood vessel walls, and then give off exosomes.

Exosomes have several key differences from stem cells; they do not get removed from the circulation like stem cells, which are in the body for less than 72 hours before they get destroyed by the immune system; they do not produce a rejection reaction because they are not a cell and contain no DNA, and they pass the blood brain barrier, Mihalcea notes. In a study on stroke scientists fluorescently tagged exosomes, and the infused exosomes went exactly to the region where the stroke had occurred, she adds. The same was not true of stem cells as they do not cross the blood brain barrier.

As a result of their powerful cargo, exosomes can be used to address a multitude of conditions, including arthritis, autoimmune disorders, cardiovascular and neurogenerative diseases like Parkinsons and Alzheimers. Old cells can be reprogrammed by MSC exosomes as the target cells can transcribe the microRNA into functional proteins. Just like a virus, the exosome information of the young stem cells can infect the old cells with Youth, explains Mihalcea.

Spinal cord injuries are an area in which exosomes have produced dramatic results. Mihalcea cites the example of Dr. Douglas J. Spiels Interventional Pain Specialty Practice in NJ. Dr. Spiel has been able to rehabilitate spinal cord injuries with Exosome infusions into the spine and intravenously, she says. After several weeks, hes had patients regain muscle strength and sensation. These are prolonged, ongoing regenerative effects that continued to improve for months after the infusion.

When it comes to autoimmune diseases, inflammation plays a key role. Again, exosomes are able to reduce the problem by downregulating inflammation. TGF Beta 3 [Transforming growth factor beta-3] is the most important anti-inflammatory protein in the body and is abundant in MSC exosomes says Mihalcea. Many more Growth factors for blood vessel growth, neuronal and other tissue growth are present, allowing regenerative effects in all organ systems including skin wounds and burns.

The exosomes at AM Medical come from a laboratory in Florida that conducted pioneering research in the field. They come from perinatal mesenchymal stem cells and are scanned for any possible viruses to ensure their safety. Once harvested, the exosomes are concentrated so they can be infused in large doses.

For patients who qualify, the infusion process takes 10 to 15 minutes. Already, its been producing results for AM Medical patients. Weve had people with arthritis and chronic pain who had great responses, Mihalcea notes. There is an overall increase in wellbeing and sense of rejuvenation that is definitely noticeable.

Perhaps one of the largest sources of excitement over exosomes has to do with their anti-aging effects. Recently, ideas about the root causes of aging have been evolving, according to Mihalcea. Its been thought that aging occurs due to multiple different reasons like stem cell exhaustion, epigenetic changes, telomere shortening and others, she explains. It turns out that exosomes can modify almost all the hallmarks of aging. Theyre changing epigenetic expression to youthful function, and there are many potential applications. This is a new frontier in regenerative medicine that can help many people.

Cutting Edge Exosome Regenerative Therapy Comes to Yelm's AM Medical - ThurstonTalk

Spinal Cord Stem Cells Comments Off on Cutting Edge Exosome Regenerative Therapy Comes to Yelm’s AM Medical – ThurstonTalk | December 12th, 2019

Biomedical engineers at Duke University have developed a system that allows for real-time observations of individual cells in the colon of a living mouse.

Researchers expect the procedure to allow new investigations into the digestive systems microbiome as well as the causes of diseases such as inflammatory bowel disease and colon cancer and their treatments.

The procedure described online today (December 11, 2019) in Nature Communications involves surgically implanting a transparent window into a mouses abdominal skin above the colon. Similar setups are already being used to allow live looks into the detailed inner workings of the brain, spinal cord, liver, lungs and other organs. Imaging a live colon, however, is a slipperier proposition.

A brain doesnt move around a lot, but the colon does, which makes it difficult to get detailed images down to a single cell, said Xiling Shen, the Hawkins Family Associate Professor of Biomedical Engineering at Duke University. Weve developed a magnetic system that is strong enough to stabilize the colon in place during imaging to obtain this level of resolution, but can quickly be turned off to allow the colon to move freely.

This video shows green fluorescent colon neurons activated by neurostimulation in real-time. This is the first time that sacral nerve stimulation, an FDA approved therapy for colon motility disorders, has definitively been shown to activate neurons in the colon in live animals, explaining why the therapy might work.

Immobilizing the colon for imaging is a tricky task for traditional methods such as glue or stitches. At best they can cause inflammation that would ruin most experiments. At worst they can cause obstructions, which can quickly kill the mouse being studied.

To skirt this issue, Shen developed a magnetic device that looks much like a tiny metal nasal strip and can be safely attached to the colon. A magnetic field snaps the colon into place and keeps it stable during imaging, but once turned off, leaves the colon free to move and function as normal.

A vital organ that houses much of the digestive systems microbiome, the colon can be afflicted by diseases such as inflammatory bowel disease, functional gastrointestinal disorders, and cancer. It also plays a key role in regulating the immune system, and can communicate directly with the brain through sacral nerves.

There is a great need to better understand the colon, because it can suffer from so many diseases and plays so many roles with significant health implications, Shen said. In the study, Shen and his colleagues conducted several proof-of-principle experiments that provide starting points for future lines of research.

The researchers first colonized a living mouse colon with E. coli bacteria, derived from Crohns disease patients, that had been tagged with fluorescent proteins. The researchers then showed they could track the migration, growth and decline of the bacteria for more than three days. This ability could help researchers understand not only how antagonistic bacteria afflict the colon, Shen says, but the positive roles probiotics can play and which strains can best help people with gastrointestinal disorders.

In the next experiment, mice were bred with several types of fluorescent immune cells. The researchers then induced inflammation in the colon and carefully watched the activation of these immune cells. Shen says, this approach could be used with various types of immune cells and diseases to gain a better understanding of how the immune system responds to challenges.

Shen and his colleagues then showed that they could tag and track colon epithelial stem cells associated with colorectal cancer throughout radiation treatment. They also demonstrated that they could watch nerves throughout the colon respond to sacral nerve stimulation, an emerging therapy for treating motility and immune disorders such as functional gastrointestinal disorders and irritable bowel disorder.

While we know electrically stimulating the sacral nerves can alleviate the symptoms of these gastrointestinal disorders, we currently have no idea why or any way to optimize these treatments, Shen said. Being able to see how the colons neurons respond to different waveforms, frequencies and amplitudes of stimulation will be invaluable in making this approach a better option for more patients.

PATIENTS with life-changing injuries could walk again thanks to a pioneering electrical spinal implant. The device has proven effective in trials on macaque monkeys and researchers in Canada are hopeful it will be available for use on human patients in as little as a decade.

Lead researcher Dr Vivian Mushahwar, of the University of Albertas Neuroscience and Mental Health Institute, said: We think that intraspinal stimulation itself will get people to start walking longer and longer, and maybe even faster.

That in itself becomes their therapy. Theres been an explosion of knowledge in neuroscience over the last 20 years.

Were at the edge of merging the human and the machine.

The device features hair-like electrical wires that plunge deep into the spinal grey matter, sending electrical signals to trigger the networks that already know how to do the hard graft.

To work alongside the implant, the team created a map to identify which parts of the spinal cord trigger the hip, knees, ankles and toes, and the areas that put movements together.

People tend to think the brain does all the thinking, but the spinal cord has built-in intelligence, said Dr Mushahwar.

A complex chain of motor and sensory networks regulate everything from breathing to bowels, while the brain stems contribution is basically go! and faster!

Your spinal cord isnt just moving muscles, its giving you your natural gait. Being able to control standing and walking would improve bone health, improve bowel and bladder function, and reduce pressure ulcers, the researchers say.

For those with less severe spinal injuries, an implant could be therapeutic, removing the need for months of gruelling physical therapy regimes that have limited success, they add. The team are now focused on refining the hardware further by miniaturising an implantable stimulator and getting approval for human trials.

The first generation of the implants will require a patient to control walking and movement through physical means, but longer term, the implants could potentially include a direct connection to the brain, they say.

Dr Mushahwar said it has the power to transform lives.

Imagine the future, a person just thinks and commands are transmitted to the spinal cord. People stand up and walk. This is the dream, she said.

WHILE they may not be as talkative as Jungle Books King Louie, it turns out wild orangutans have some serious communication skills.

Researchers at the University of Exeter in Devon have identified 11 vocal signals and 21 physical gesture types that the apes use to communicate with one another.

The findings reveal orangutans are highly responsive to communication, reacting either before gesturing ended or in less than a second in 90 per cent of communications.

The team studied video footage of 16 orangutans consisting of seven mother-child pairs and a pair of siblings, noting a total of 1,299 communicative signals 858 vocal signals and 441 gestures.

The sounds included the kiss squeak a sharp kiss noise created while inhaling the grumph (a low sound lasting one or two seconds made on the inhale), the gorkum (a kiss squeak followed by a series of multiple grumphs) and the self-explanatory raspberry.

Gestures included beckoning, stamping, pushing out a lower lip, shaking objects and presenting a body part.

The eight identified goals or requests of their communications are acquire object, climb on me, climb on you, climb over, move away, decrease intensity, resume play and stop that.

Orangutans are the most solitary of all the apes, which is why most studies have been done on African apes, and not much is known about wild orangutan gestures, said University of Exeter scientist Dr Helen Morrogh-Bernard. We spent two years filming more than 600 hours of footage of orangutans in the Sabangau peat swamp forest in Borneo, Indonesia.

While some of our findings support what has been discovered by zoo-based studies, other aspects are new and these highlight the importance of studying communication in its natural context.

More signals are likely to be identified in the future, the researchers say.

WE MAY like to put our feet up at Christmas but for older people, even a short period of reduced physical activity could lead to significant loss of muscle mass and gains in body fat.

Just a fortnight of walking fewer than 1,500 steps a day could have a severe impact making daily tasks harder and kick-starting chronic health conditions a University of Liverpool study found.

The team measured the effect of two weeks inactivity on 47 participants, around half of whom were elderly. All lost muscle size, strength and bone mass. But the older volunteers also experienced a big drop in cardio fitness and mitochondrial function the way cells produce energy.

If the gym is hard to get to, people should be encouraged to just meet 10,000 steps, said researcher Juliette Norman. Even this can guard against reductions in muscle and bone health as well as maintaining healthy levels of body fat.

EXPERIENCING stress at a young age could help you live longer. Juvenile Caenorhabditis elegans worms that produce more oxidants and free radicals, which are associated with stress and ageing, last longer, US researchers at the University of Michigan found. Study leader Daphne Bazopoulou said early exposure may make you better able to fight stress later in life.

AGE can be predicted by protein levels in the blood. Using blood samples from more than 4,000 18- to 95-year-olds, scientists at Stanford University, California, found 373 proteins that peak and trough across a lifespan. The blood test can also show how physiological and real ages compare, which could flag those more at risk of ageing-related illnesses or reveal the ageing effect of drugs and treatments.

To brag flagrantly is, most of us realise, unbecoming, and so a favoured mitigation tactic has emerged: the humblebrag. This is a way of masking a boast, either in a feigned complaint or as fake modesty, such as its so exhausting staying in touch with all my friends or if someone told me Id pass with first-class honours, Id never have believed them. Unfortunately for humblebraggers, the tactic is too transparent to work. Last year, researchers at the University of North Carolina and Harvard Business School found humblebraggers are less liked, and perceived as less competent, because they appear insincere.

Astronomers have found magnetic field strengths near supermassive black holes can be as strong as their intense gravitational fields. These fields are able to expel material from the vicinity of the black hole to form highly energetic outflows called jets. However, this process is not acting on material that has already passed beyond the black holes event horizon, where not even light can escape. Such material would need to be accelerated to the speed of light to escape, which would require an infinite amount of energy. No magnet, however powerful, could provide this.

A campaign has been launched to fund vital research into Multiple Sclerosis in Sheffield. Catherine Scott reports.

Sheffield Hospitals Charity is appealing for support to fund a new research project being undertaken in the city that could help find a cure for Multiple Sclerosis (MS).

MS affects more than 100,000 people in the UK and is the most common cause of physical disability in young adults. It can cause pain, fatigue, problems with memory and thinking, speech and vision problems, but most noticeably, loss of mobility.

The disease occurs when the bodys immune system becomes faulty, instead of protecting against viruses and germs, the immune system attacks the nerve fibres in the brain and spinal cord.

Currently, there is no effective treatment for MS and existing treatments focus on alleviating symptoms and their impact on long term disability. But Sheffield scientists Professor Basil Sharrack and Professor John Snowden are determined to find better treatments and even a cure for MS.

One of these 100,000 people, and a patient of Professors Sharrack and Snowden, is Allison Parfitt, 50 from Sheffield who has had MS since 2008.

Allison explained the impact this had on her life: When I was diagnosed, I felt like my whole world was falling apart around me. MS controls my life. I feel exhausted all over my whole body is tired, right down to my fingertips.

Some days, every move I make is like walking through quick sand, everything is slower. My mind feels like theres a fog inside it, stopping me from concentrating or thinking clearly. My legs wont support me anymore, so I have to use crutches or a wheelchair to get around.

Im a very independent person but that is being taken away from me. I cant even go to the shops on my own anymore, I need someone with me.

The research going on here in Sheffield gives me hope. Hope that one day, Ill receive that call to say a cures been found. It would be good to know that people in the future wont have to go through what I have.

The project will be delivered by Professor Basil Sharrack, Consultant Neurologist and Professor John Snowden, Consultant Haematologist from Sheffield Teaching Hospitals.

Professor Sharrack explained how supporting his research could help future patients like Allison.

For the first time ever, weve been able to reverse disability in some patients with MS using a brand new stem cell therapy trialled right here in Sheffield and its like nothing weve seen before.

First we destroy the faulty immune system that causes MS and then we replace it with a healthy new one, grown from a patients own stem cells. In some patients it has reversed some of the disabilities associated with their MS condition, but this isnt suitable for everyone as stem cell treatment can be quite aggressive.

The pair wants to build upon the success of their stem cell work by trying to identify a biomarker a test which will allow clinicians to predict how each patients disease is likely to progress.

Professor John Snowden explained further: Once a biomarker is identified, it can be used to measure the progression of MS and predict how the disease will develop and how it will respond to treatment.

This could help us revolutionise the way in which MS patients are treated. Doctors will be able to make more informed choices about which treatment course to follow and when to start and escalate the treatment to prevent long-term disability.

We will gain a crucial understanding about how MS works, which will help provide new information that could help identify new drugs that could potentially cure MS.

For the first time, it feels like a cure for MS could be right around the corner. Thats why it is so critical that our research goes ahead.

No other hospital in the UK combines neurology and haematology in the way we do here in Sheffield we are in a unique position. We want to get started with our research as soon as possible so that people living with MS right now can benefit from the discoveries we make. By donating to Sheffield Hospitals Charitys Multiple Sclerosis Appeal you could help create a better future for people like Allison.

Sheffield Hospitals Charity is aiming to raise 200,000 to support the research project. Anyone interested in donating or fundraising to enable the MS research to be undertaken can find out more at http://www.sheffieldhospitalscharity.org.uk/msresearch

Led by researchers at Baylor College of Medicine, a study published in the journal Cell Stem Cell reveals a new mechanism that contributes to adult bone maintenance and repair and opens the possibility of developing therapeutic strategies for improving bone healing.

Adult bone repair relies on the activation of bone stem cells, which still remain poorly characterized, said corresponding author Dr. Dongsu Park, assistant professor of molecular and human genetics and of pathology and immunology at Baylor. Bone stem cells have been found both in the bone marrow inside the bone and also in the periosteum the outer layer of tissue that envelopes the bone. Previous studies have shown that these two populations of stem cells, although they share many characteristics, also have unique functions and specific regulatory mechanisms.

Of the two, periosteum stem cells are the least understood. It is known that they comprise a heterogeneous population of cells that can contribute to bone thickness, shaping and fracture repair, but scientists had not been able to distinguish between different subtypes of bone stem cells to study how their different functions are regulated.

In the current study, Park and his colleagues developed a method to identify different subpopulations of periosteum stem cells, define their contribution to bone fracture repair in live mouse models and identify specific factors that regulate their migration and proliferation under physiological conditions.

Periosteal stem cells are major contributors to bone healing

The researchers discovered specific markers for periosteum stem cells in mouse models. The markers identified a distinct subset of stem cells that contributes to life-long adult bone regeneration.

We also found that periosteum stem cells respond to mechanical injury by engaging in bone healing, Park said. They are important for healing bone fractures in the adult mice and, interestingly, their contribution to bone regeneration is higher than that of bone marrow stem cells.

In addition, the researchers found that periosteal stem cells also respond to inflammatory molecules called chemokines, which are usually produced during bone injury. In particular, they responded to chemokine CCL5.

Periosteal stem cells have receptors molecules on their cell surface that bind to CCL5, which sends a signal to the cells to migrate toward the injured bone and repair it. Deleting the CCL5 gene in mouse models resulted in marked defects in bone repair or delayed healing. When the researchers supplied CCL5 to CCL5-deficient mice, bone healing was accelerated.

The findings suggested potential therapeutic applications. For instance, in individuals with diabetes or osteoporosis in which bone healing is slow and may lead to other complications resulting from limited mobility, accelerating bone healing may reduce hospital stay and improve prognosis.

Our findings contribute to a better understanding of how adult bones heal. We think this is one of the first studies to show that bone stem cells are heterogeneous and that different subtypes have unique properties regulated by specific mechanisms, Park said. We have identified markers that enable us to tell bone stem cell subtypes apart and studied what each subtype contributes to bone health. Understanding how bone stem cell functions are regulated offers the possibility to develop novel therapeutic strategies to treat adult bone injuries.
