Stem Cell Therapy May Be The Cure For Spinal Cord Injury …

By admin

06/06/2018

A stem cell treatment which is in primary stages of trials, has proved effective in treatment when using non-donor stem cells.

Spinal cord injuries can happen to anyone, the condition tends to be a result of a fall or accident, although it can also be an outcome of a brain injury. When the spinal cord is injured the pathway is practically closed. Nerve impulses cant get through, this has problematic symptoms such as; a person suffering paralysis, a loss of mobility and sensation.

Using stem cell therapy where the stem cells havent been donated mean they are more likely to be accepted by the patient when they are injected.

This new trial was published on the 9th of May 2018 inScience Translational Medicine, a team of international scientist led by the University of California San Diego School of Medicine successfully grafted stem cells back into a spinal cord without aggravating the immune system or reducing it in any way.

The stem cells injected in the trial were accepted and survived long term without causing a tumor. Researchers also found that the same cells showed a long-term survival when injected into an injured spinal cord.

Senior author Martin Marsala, MD, professor in the Department of Anesthesiology at UC San Diego School of Medicine and a member of the Sanford Consortium for Regenerative Medicine, said: The promise of iPSCs is huge, but so too have been the challenges. In this study, weve demonstrated an alternate approach,

We took skin cells, then induced them to becomeneural precursor cells(NPCs), destined to become nerve cells. Because they are syngeneicgenetically identical with the cell-graftthey are immunologically compatible. They grow and differentiate with no immunosuppression required.

Co-author Samuel Pfaff, PhD, professor and Howard Hughes Medical Institute Investigator at Salk Institute for Biological Studies, said: Using RNA sequencing and innovative bioinformatic method to deconvolute the RNAs species-of-origin, the research team demonstrated that iPSC-derived neural precursors safely acquire the genetic characteristics of mature CNS tissue.

In their study, researchers found that the stem cells survived and differentiated into neurons and supporting glial cells. The grafted stem cells were detected to be working and responsive seven months after transplantation.

Researchers, then grafted stem cells into similar tissues in the body that had severespinal cord injuries, this injection of stem cells was then followed by a transient four-week course of drugs that suppress the immune system. The stem cells then could work in the spinal cord and begin to allow movement.

Our current experiments are focusing on generation and testing of clinical grade human iPSCs, which is the ultimate source of cells to be used in future clinical trials for treatment of spinal cord and central nervous system injuries in a syngeneic or allogeneic setting, said Marsala.

Because long-term post-grafting periodsone to two yearsare required to achieve a full graftedcells-induced treatment effect, the elimination of immunosuppressive treatment will substantially increase our chances in achieving more robust functional improvement in spinal trauma patients receiving iPSC-derived NPCs.

In our current clinical cell-replacement trials, immunosuppression is required to achieve the survival of allogeneic cell grafts. The elimination of immunosuppression requirement by using syngeneic cell grafts would represent a major step forward said co-author Joseph Ciacci, MD, a neurosurgeon at UC San Diego Health and professor of surgery at UC San Diego School of Medicine.

The treatment is expected to go to the next stage of trials in the next few years, with the hope that this stem cell therapy can be used in modern medicine.

This research forms another significant step towards stem cell therapy and spinal cord injury. Yet the type of cell used is still in contention when it comes to human application. iPSC are undoubtedlyauseful research tool in the laboratory and as a result because of their pluripotency, many scientists continue to hopethat they can one day be used for therapeutic applications, including regenerative medicine in humans. This strategy continues to proveproblematic ashave been shown to produce lesions and tumors when injected or transplanted.

This type of research does however contribute to ongoing developments for the use of stem cells, where possible use of Adult Stem Cells, known not to be problematic as a result of tumors could be used.

We believe the best stem cells to use in emergingtreatmentswill be the patients own stem cells as this doesnt require a search for a suitable donor and in turn, eliminates chances of the transplanted cells being rejected.

Stem cells have the potential to differentiate into cardiovascular cell lineages and to stimulate tissue regeneration in a paracrine/autocrine manner; thus, they have been extensively studied as candidate cell sources for cardiovascular regeneration. Several preclinical and clinical studies addressing the therapeutic potential of endothelial progenitor cells (EPCs) and cardiac progenitor cells (CPCs) in cardiovascular diseases have been performed. For instance, autologous EPC transplantation and EPC mobilization through pharmacological agents contributed to vascular repair and neovascularization in different animal models of limb ischemia and myocardial infarction. Also, CPC administration and in situ stimulation of resident CPCs have been shown to improve myocardial survival and function in experimental models of ischemic heart disease. However, clinical studies using EPC- and CPC-based therapeutic approaches have produced mixed results. In this regard, intracoronary, intra-myocardial or intramuscular injection of either bone marrow-derived or peripheral blood progenitor cells has improved pathological features of tissue ischemia in humans, despite modest or no clinical benefit has been observed in most cases. Also, the intriguing scientific background surrounding the potential clinical applications of EPC capture stenting is still waiting for a confirmatory proof. Moreover, clinical findings on the efficacy of CPC-based cell therapy in heart diseases are still very preliminary and based on small-size studies.

Despite promising evidence, widespread clinical application of both EPCs and CPCs remains delayed due to several unresolved issues. The present review provides a summary of the different applications of EPCs and CPCs for cardiovascular cell therapy and underlies their advantages and limitations.

Nicholas Geissse, PhD, CSO, NanoSurface Biomedical

Alec S.T. Smith, PhD, Acting Instructor, Bioengineering, University of Washington

hiPSC-CM maturation is sensitive to structural cues from the extracellular matrix (ECM). Failure to reproduce these signals in vitro can hamper experimental reproducibility and fidelity. Engineering approaches that address this gap typically trade off complexity with throughput, making them difficult to deploy in the modern drug development paradigm. The NanoSurface Car(ina) platform leverages ECM engineering approaches that are fully compatible with industry-standard instrumentation including HCI- and MEA-based assays, thereby improving their predictive power.

The role of innate immune cells in health and disease, respectively their function in maintaining immune homeostasis and triggering inflammation makes them a prime target for therapeutic approaches. In order to explore novel therapeutic strategies to enhance immunoregulatory functions, we developed an iPSC-based cellular drug discovery platform. Here we will highlight the unique opportunities provided by an iPSC-based drug discovery platform for targeting innate immune cells.

3:40 Phenotypic Screening of Induced Pluripotent Stem Cell Derived Cardiomyocytes for Drug Discovery and Toxicity Screening

Arne Bruyneel, PhD, Postdoctoral Fellow, Mark Mercola Lab, Cardiovascular Institute, Stanford University School of Medicine

Cardiac arrhythmia and myopathy is a major problem with cancer therapeutics, including newer small molecule kinase inhibitors, and frequently causes heart failure, morbidity and death. However, currentin vitromodels are unable to predict cardiotoxicity, or are not scalable to aid drug development. However, with recent progress in human stem cell biology, cardiac differentiation protocols, and high throughput screening, new tools are available to overcome this barrier to progress.

4:10 Disease Modeling Using Human iPSC-Derived Telencephalic Inhibitory Interneurons - A Couple of Case Studies

Yishan Sun, PhD, Investigator, Novartis Institutes for BioMedical Research (NIBR)

Human iPSC-derived neurons provide the foundation for phenotypic assays assessing genetic or pharmacological effects in a human neurobiological context. The onus is on assay developers to generate application-relevant neuronal cell types from iPSCs, which is not always straightforward, given the diversity of neuronal classes in the human brain and their developmental trajectories. Here we present two case studies to illustrate the use of iPSC-derived telencephalic GABAergic interneurons in neuropsychiatric research.

8:15 Levering iPSC to Understand Mechanism of Toxicity

Jeff Willy, PhD, Research Fellow, Discovery and Investigative Toxicology, Vertex

The discovery of mammalian cardiac progenitor cells suggests that the heart consists of not only terminally differentiated beating cardiomyocytes, but also a population of self-renewing stem cells. We recently showed that iPSC cardiomyocytes can be utilized not only to de-risk compounds with potential for adverse cardiac events, but also to understand underlying mechanisms of cell-specific toxicities following xenobiotic stress, thus preventing differentiation and self-renewal of damaged cells.

8:45Pluripotent Stem Cell-Derived Cardiac and Vascular Progenitor Cells for Tissue Regeneration

Nutan Prasain, PhD, Associate Director, Cardiovascular Programs, Astellas Institute for Regenerative Medicine (AIRM)

This presentation will provide the review on recent discoveries in the derivation and characterization of cardiac and vascular progenitor cells from pluripotent stem cells, and discuss the therapeutic potential of these cells in cardiac and vascular tissue repair and regeneration.

9:15 Use of iPSCDerived Hepatocytes to Identify Treatments for Liver Disease

Stephen A. Duncan, PhD, Smartstate Chair in Regenerative Medicine, Professor and Chairman, Department of Regenerative Medicine and Cell Biology, Medical University of South Carolina

MTDPS3 is a rare disease caused by mutations in the DGUOK gene, which is needed for mitochondrial DNA (mtDNA) replication and repair. Patients commonly die as children from liver failure primarily caused by unmet energy requirements. We modeled the disease using DGOUK deficient iPSC derived hepatocytes and performed a screen to identify drugs that can restore mitochondrial ATP production.

Lorenz Studer, MD, Director, Center for Stem Cell Biology, Memorial Sloan Kettering Cancer Center

One of the most intriguing applications of human pluripotent stem cells is the possibility of recreating a disease in a dish and to use such cell-based models for drug discovery. Our lab uses human iPS and ES cells for modeling both neurodevelopmental and neurodegenerative disorders. I will present new data on our efforts of modeling complex genetic disease using pluripotent stem cells and the development of multiplex culture systems.

11:30 Preclinical Challenges for Gene Therapy Approaches in Neuroscience

Gabriele Proetzel, PhD, Director, Neuroscience Drug Discovery, Takeda Pharmaceuticals, Inc.

Gene therapy has delivered encouraging results in the clinic, and with the first FDA approval for an AAV product is now becoming a reality. This presentation will provide an overview of the most recent advances of gene therapy for the treatment of neurological diseases. The discussion will focus on preclinical considerations for gene therapy including delivery, efficacy, biodistribution, animal models and safety.

12:00 pm Open Science Meets Stem Cells: A New Drug Discovery Approach for Neurodegenerative Disorders

Thomas Durcan, PhD, Assistant Professor, Neurology and Neurosurgery, McGill University

Advances in stem cell technology have provided researchers with tools to generate human neurons and develop first-of-their-kind disease-relevant assays. However, it is imperative that we accelerate discoveries from the bench to the clinic and the Montreal Neurological Institute (MNI) and its partners are piloting an Open Science model. By removing the obstacles in distributing patient samples and assay results, our goal is to accelerate translational medical research.

12:30 Elevating Drug Discovery with Advanced Physiologically Relevant Human iPSC-Based Screening Platforms

Fabian Zanella, PhD, Director, Research and Development, StemoniX

Structurally engineered human induced pluripotent stem cell (hiPSC)-based platforms enable greater physiological relevance, elevating performance in toxicity and discovery studies. StemoniXs hiPSC-derived platforms comprise neural (microBrain) or cardiac (microHeart) cells constructed with appropriate inter- and intracellular organization promoting robust activity and expected responses to known cellular modulators.

1:00Overcoming Challenges in CNS Drug Discovery through Developing Translatable iPSC-derived Cell-Based Assays

Jonathan Davila, PhD, CEO, Co-Founder, NeuCyte Inc.

Using direct reprogramming of iPSCs to generate defined human neural tissue, NeuCyte developed cell-based assays with complex neuronal structure and function readouts for versatile pre-clinical applications. Focusing on electrophysiological measurements, we demonstrate the capability of this approach to identify adverse neuroactive effects, evaluate compound efficacy, and serve phenotypic drug discovery.

2:25 The Evolving Roles of Evolving Human Stem Cell-Derived Cardiomyocyte Preparations in Cardiac Safety Evaluations

Gary Gintant, PhD, Senior Research Fellow, AbbVie

Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) hold great promise for preclinical cardiac safety testing. Recent applications focus on drug effects on cardiac electrophysiology, contractility, and structural toxicities, with further complexity provided by the growing number of hiPSC-CM preparations being developed that may also promote myocyte maturity. The evolving roles (both non-regulatory and regulatory) of these preparations will be reviewed, along with general considerations for their use in cardiac safety evaluations.

2:55 Pharmacogenomic Prediction of Drug-Induced Cardiotoxicity Using hiPSC-Derived Cardiomyocytes

Paul W. Burridge, PhD, Assistant Professor, Department of Pharmacology, Center for Pharmacogenomics, Northwestern University Feinberg School of Medicine

We have demonstrated that human induced pluripotent stem cell-derived cardiomyocytes successfully recapitulate a patients predisposition to chemotherapy-induced cardiotoxicity, confirming that there is a genomic basis for this phenomenon. Here we will discuss our recent work deciphering the pharmacogenomics behind this relationship, allowing the genomic prediction of which patients are likely to experience this side effect. Our efforts to discover new drugs to prevent doxorubicin-induced cardiotoxicity will also be reviewed.

3:25 Exploring the Utility of iPSC-Derived 3D Cortical Spheroids in the Detection of CNS Toxicity

Qin Wang, PhD, Scientist, Drug Safety Research and Evaluation, Takeda

Drug-induced Central Nervous System (CNS) toxicity is a common safety attrition for project failure during discovery and development phases due low concordance rates between animal models and human, absence of clear biomarkers, and a lack of predictive assays. To address the challenge, we validated a high throughput human iPSC-derived 3D microBrain model with a diverse set of pharmaceuticals. We measured drug-induced changes in neuronal viability and Ca channel function. MicroBrain exposure and analyses were rooted in therapeutic exposure to predict clinical drug-induced seizures and/or neurodegeneration. We found that this high throughput model has very low false positive rate in the prediction of drug-induced neurotoxicity.

3:55 Linking Liver-on-a-Chip and Blood-Brain-Barrier-on-a-Chip for Toxicity Assessment

Sophie Lelievre, DVM, PhD, LLM, Professor, Cancer Pharmacology, Purdue University College of Veterinary Medicine

One of the challenges to reproduce the function of tissues in vitro is the maintenance of differentiation. Essential aspects necessary for such endeavor involve good mechanical and chemical mimicry of the microenvironment. I will present examples of the management of the cellular microenvironment for liver and blood-brain-barrier tissue chips and discuss how on-a-chip devices may be linked for the integrated study of the toxicity of drugs and other molecules.

Heart Disease A Closer Look at Stem Cells

By admin

Overview of current stem cell-based approaches to treat heart disease

Since heart failure after heart attacks results from death of heart muscle cells, researchers have been developing strategies to remuscularize the damaged heart wall in efforts to improve its function. Researchers are transplanting different types of stem cell and progenitor cells (see above) into patients to repair the damaged heart muscle. These strategies have mainly used either adult stem cells (found in bone marrow, fat, or the heart itself) or pluripotent (ES or iPS) cells.

Preliminary results from experiments with adult stem cells showed that they appeared to improve cardiac function even though they died shortly after transplantation. This led to the idea that these cells can release signals that can improve function without replacing the lost muscle. Clinical trials began in the early 2000s transplanting adult stem cells from the bone marrow and then from the heart. These trials demonstrated that transplanting cells into damaged hearts is feasible and generally safe for patients. However, larger trials that were randomized, blinded, and placebo-controlled, showed fewer indications of improved function. The consensus now is that adult stem cells have modest, if any, benefit to cardiac function.

Research shows that pluripotent stem cell-derived cardiomyocytes can form beating human heart muscle cells that both release the necessary signals and replace muscle lost to heart attack. Transplantation of pluripotent stem cell-derived cardiac cells have demonstrated substantial benefits to cardiac function in animal models of heart disease, from mice to monkeys. Recently, pluripotent stem cell-derived interventions were used in clinical trials for the first time. Patches of human heart muscle cells derived from the stem cells were transplanted onto the surface of failing hearts. Early results suggest that this approach is feasible and safe, but it is too early to know whether there are functional benefits.Research is ongoing to test cellular therapies to treat heart attacks by combining different types of stem cells, repeating transplantations, or improving stem cell patches. Clinical trials using these improved methods are currently targeted to begin around 2020.Unfortunately, many unscrupulous clinics are making unsubstantiated claims about the efficacy of stem cell therapies for heart failure, creating confusion about the current state of cellular approaches for heart failure.

Stem Cells for Skin Quality – innovationsstemcellcenter.com

By admin

Stem cells can do a lot of things - they can heal damaged tissue, reduce inflammation and restore function to damaged tissues. Did you know that stem cells can also improve your skin's quality and reduce the signs of aging? Innovations Stem Cell Center offers fat stem cell therapy for not only a wide array of medical conditions, but also for powerful anti-aging benefits.

How Can Stem Cell Therapy Improve Skin Quality?

Stem cells can help improve skin quality by helping to heal tissues that have been damaged by:

Aging. The aging process causes the breakdown of skin cells and skin quality, leaving the skin looking dull and dirty. Skin also loses elasticity and tightness.

Genetics. Genetics plays a large part in how your skin ages, and it's hard to fight it with over-the-counter products and treatments.

Poor diet. Lack of quality nutrition can negatively impact both the body and the skin. When the skin is not supported through a healthy diet, skin becomes dull, drab and damaged.

Environment. Environmental factors that affect the skin include pollution, dirt and germs. These things clog the pores, dull your appearance and lead to blemishes, acne and breakouts. Environmental factors also include prolonged exposure to the sun, which can cause pigmentation problems and destroy collagen and elastin.

How Is Stem Cell Therapy Used for the Skin?

One of the ways stem cell therapy is used for the skin is through a stem cell face-lift procedure. During this treatment, Dr. Johnson harvests stem cells from unwanted fat taken from another area of your body, such as your lower back or abdomen.

After the cells are harvested, they are separated from the blood and other tissue and then injected into your face with tiny needles.

The stem cell face-lift can be combined with other procedures, such as the facial fat transfer. Combining the procedures increases the odds of stem cell survival and boosts the anti-aging benefits.

What Are the Benefits of Stem Cell Therapy for the Skin?

Patients who undergo stem cell therapy for anti-aging benefits see changes in their skin such as:

NSI-566 grafted injured spines in rats with near complete cavity-filling

The differentiation profile of grafted cells showed all three neural lineage cells

High-density human axonal sprouting was seen throughout the NSI-566 grafted region

NSI-566 transplanted in the spinal injury site of patients can be performed safely

We tested the feasibility and safety of human-spinal-cord-derived neural stem cell (NSI-566) transplantation for the treatment of chronic spinal cord injury (SCI). In this clinical trial, four subjects with T2T12 SCI received treatment consisting of removal of spinal instrumentation, laminectomy, and durotomy, followed by six midline bilateral stereotactic injections of NSI-566 cells. All subjects tolerated the procedure well and there have been no serious adverse events to date (1827months post-grafting). In two subjects, one to two levels of neurological improvement were detected using ISNCSCI motor and sensory scores. Our results support the safety of NSI-566 transplantation into the SCI site and earlysigns of potential efficacy in three of the subjects warrant further exploration of NSI-566 cells in dose escalation studies. Despite these encouraging secondary data, we emphasize that this safety trial lacks statistical power or a control group needed to evaluate functional changes resulting from cell grafting.

Figure 1. hPSC Single-Cell Cloning Workflow with CloneR

On day 0, human pluripotent stem cells (hPSCs) are seeded as single cells at clonal density (e.g. 25 cells/cm2) or sorted at 1 cell per well in 96-well plates in TeSR (mTeSR1 or TeSR-E8) medium supplemented with CloneR. On day 2, the cells are fed with TeSR medium containing CloneR supplement. From day 4, cells are maintained in TeSR medium without CloneR. Colonies are ready to be picked between days 10 - 14. Clonal cell lines can be maintained long-term in TeSR medium.

Figure 2. CloneR Increases the Cloning Efficiency of hPSCs and is Compatible with Multiple hPSC Lines and Seeding Protocols

TeSR medium supplemented with CloneR increases hPSC cloning efficiency compared with cells plated in TeSR containing ROCK inhibitor. Cells were seeded (A) at clonal density (25 cells/cm2) in mTeSR1 and TeSR-E8 and (B) by single-cell deposition using FACS (seeded at 1 cell/well) in mTeSR1.

Figure 3. CloneR Increases the Cloning Efficiency of hPSCs at Low Seeding Densities

hPSCs plated in mTeSR1 supplemented with CloneR demonstrated significantly increased cloning efficiencies compared to cells plated in mTeSR1 containing ROCK inhibitor (10M Y-27632). Shown are representative images of alkaline phosphatase-stained colonies at day 7 in individual wells of a 12-well plate. H1 human embryonic stem (hES) cells were seeded at clonal density (100 cells/well, 25 cells/cm2) in mTeSR1 supplemented with (A) ROCK inhibitor or (B) CloneR on Vitronectin XF cell culture matrix.

Figure 4. CloneR Yields Larger Single-Cell Derived Colonies

hPSCs seeded in mTeSR1 supplemented with CloneR result in larger colonies than cells seeded in mTeSR1 containing ROCK inhibitor (10M Y-27632). Shown are representative images of hPSC clones established after 7 days of culture in mTeSR1 supplemented with (A) ROCK inhibitor or (B) CloneR.

Figure 5. Clonal Cell Lines Established Using CloneR Display Characteristic hPSC Morphology

Clonal cell lines established using mTeSR1 or TeSR-E8 medium supplemented with CloneR retain the prominent nucleoli and high nuclear-to-cytoplasmic ratio characteristic of hPSCs. Representative images at passage 7 after cloning are shown for clones derived from the parental (A) H1 hES cell and (B) WLS-1C human induced pluripotent stem (iPS) cell lines.

Figure 6. Clonal Cell Lines Established with CloneR Express High Levels of Undifferentiated Cell Markers

hPSC clonal cell lines established using mTeSR1 supplemented with CloneR express comparable levels of undifferentiated cell markers, OCT4 (Catalog #60093) and TRA-1-60 (Catalog #60064), as the parental cell lines. (A) Clonal cell lines established from parental H1 hES cell line. (B) Clonal cell lines established from parental WLS-1C hiPS cell line. Data is presented between passages 5 - 7 after cloning and is shown as mean SEM; n = 2.

Figure 7. Clonal Cell Lines Established Using CloneR Display a Normal Karyotype

Representative karyograms of clones derived from parental (A) H1 hES cell and (B) WLS-1C hiPS cell lines demonstrate that the clonal lines established with CloneR have a normal karyotype. Cells were karyotyped 5 passages after cloning, with an overall passage number of 45 and 39, respectively.

Figure 8. Clonal Cell Lines Established Using CloneR Display Normal Growth Rates

Fold expansion of clonal cell lines display similar growth rates to parental cell lines. Shown are clones (red) and parental cell lines (gray) for (A) H1 hES cell and (B) WLS-1C hiPS cell lines.

Bone marrow mesenchymal stem cells: Aging and tissue …

Bone has well documented natural healing capacity that normally is sufficient to repair fractures and other common injuries. However, the properties of bone change throughout life, and aging is accompanied by increased incidence of bone diseases and compromised fracture healing capacity, which necessitate effective therapies capable of enhancing bone regeneration. The therapeutic potential of adult mesenchymal stem cells (MSCs) for bone repair has been long proposed and examined. Actions of MSCs may include direct differentiation to become bone cells, attraction and recruitment of other cells, or creation of a regenerative environment via production of trophic growth factors. With systemic aging, MSCs also undergo functional decline, which has been well investigated in a number of recent studies. In this review, we first describe the changes in MSCs during aging and discuss how these alterations can affect bone regeneration. We next review current research findings on bone tissue engineering, which is considered a promising and viable therapeutic solution for structural and functional restoration of bone. In particular, the importance of MSCs and bioscaffolds is highlighted. Finally, potential approaches for the prevention of MSC aging and the rejuvenation of aged MSC are discussed.

What Can Stem Cells Do For Your Skin? | Skeyndor Australia

By admin

Did you know that around 10,000 skin cells are born from one stem cell? Skin cells are constantly regenerating and on average live for 21 days. They make their way up from the deepest layers of your skin where they then die protecting themselves from external aggressors. As the engine for the constant renewal of your skin it is important we nourish and protect precious stem cells so they can keep producing your best skin.

As you age the activity of stem cells decrease. This is when you start to notice those first signs of ageing; thinner and more delicate skin, sagging, wrinkles and lack of luminosity. After the age of 40, the skins regeneration cycle slows down. New skin cells take longer to reach the surface of the skin, and dead cells can take twice as long to disappear, affecting the youthful appearance of your skin.

Do skincare products and skin treatments with stem cells make sense before the age of 40?Yes!

Young skin regenerates more quickly, and to mimic this we suggest an aggressive treatment, such as a peel, which removes lots of dead skin cells at once, to thenhelp your stem cells to renew andactivate the production of new, healthy and strong skin cells more quickly. Then we recommend stem cell skin products and treatments.

How exactly does a stem cell treatment work? The answer seems simple, but it is the result of many years of scientific research to ensure proven results. At Skeyndor we can guarantee this thanks to our laboratories with more than 50 years of experience in cosmeceuticals. Thanks to our incredible scientists, who have been at the forefront of skin stem cell innovations and breakthroughs we have developed two lines that contain stem cells.

About stem cells

Stem cells are the foundation of development in plants, animals and humans. In humans, there are many different types of stem cells that come from different places in the body or are formed at different times in our lives. These include embryonic stem cells that exist only at the earliest stages of development and various types oftissue-specific(oradult)stem cells that appear during fetal development and remain in our bodies throughout life.Stem cells are defined by two characteristics:

Beyond these two things, though, stem cells differ a great deal in their behaviors and capabilities.

Embryonic stem cells arepluripotent, meaning they can generate all of the bodys cell types but cannot generate support structures like the placenta and umbilical cord.

Other cells aremultipotent,meaning they can generate a few different cell types, generally in a specific tissue or organ.

As the body develops and ages, the number and type of stem cells changes. Totipotent cells are no longer present after dividing into the cells that generate the placenta and umbilical cord. Pluripotent cells give rise to the specialized cells that make up the bodys organs and tissues. The stem cells that stay in your body throughout your life are tissue-specific, and there is evidence that these cells change as you age, too your skin stem cells at age 20 wont be exactly the same as your skin stem cells at age 80.

Preconditioning of bone marrow-derived mesenchymal stem …

JavaScript is disabled on your browser. Please enable JavaScript to use all the features on this page.Abstract

Oxidative stress on transplanted bone marrow-derived mesenchymal stem cells (BMSCs) during acute inflammation is a critical issue in cell therapies. N-acetyl-L cysteine (NAC) promotes the production of a cellular antioxidant molecule, glutathione (GSH). The aim of this study was to investigate the effects of pre-treatment with NAC on the apoptosis resistance and bone regeneration capability of BMSCs. Rat femur-derived BMSCs were treated in growth medium with or without 5mM NAC for 6h, followed by exposure to 100MH2O2 for 24h to induce oxidative stress. Pre-treatment with NAC significantly increased intracellular GSH levels by up to two fold and prevented H2O2-induced intracellular redox imbalance, apoptosis and senescence. When critical-sized rat femur defects were filled with a collagen sponge containing fluorescent-labeled autologous BMSCs with or without NAC treatment, the number of apoptotic and surviving cells in the transplanted site after 3 days was significantly lower and higher in the NAC pre-treated group, respectively. By the 5th week, significantly enhanced new bone formation was observed in the NAC pre-treated group. These data suggest that pre-treatment of BMSCs with NAC before local transplantation enhances bone regeneration via reinforced resistance to oxidative stress-induced apoptosis at the transplanted site.

Human iPS cell-derived neural progenitors influence the contractile property of cardiac spheroid.

The contractile function of spheroids depends on the ratio of neural progenitors to cardiac cells.

Neural factors may influence the contractile function of the spheroids.

We havebeen attempting to use cardiac spheroids to construct three-dimensional contractilestructures for failed hearts. Recent studies have reported that neuralprogenitors (NPs) play significant roles in heart regeneration. However, theeffect of NPs on the cardiac spheroid has not yet been elucidated.

This studyaims to demonstrate the influence of NPs on the function of cardiac spheroids.

Thespheroids were constructed on a low-attachment-well plate by mixing humaninduced pluripotent stem (hiPS) cell-derived cardiomyocytes and hiPScell-derived NPs (hiPS-NPs). The ratio of hiPS-NPs was set at 0%, 10%, 20%,30%, and 40% of the total cell number of spheroids, which was 2500. The motionwas recorded, and the fractional shortening and the contraction velocity weremeasured.

Spheroidswere formed within 48 h after mixing the cells, except for the spheroidscontaining 0% hiPS-NPs. Observation at day 7 revealed significant differencesin the fractional shortening (analysis of variance; p=0.01). The bestfractional shortening was observed with the spheroids containing 30% hiPS-NPs.Neuronal cells were detected morphologically within the spheroids under aconfocal microscope.

Theaddition of hiPS-NPs influenced the contractile function of the cardiacspheroids. Further studies are warranted to elucidate the underlying mechanism.

Skin stem cells: where do they live and what can they do? | Eurostemcell – Stem Cell Research | Uses of Stem Cells and Ethics | EuroStemCell

By admin

One of the current challenges for stem cell researchers is to understand how all the skin appendages are regenerated. This could lead to improved treatments for burn patients, or others with severe skin damage.

Researchers are also working to identify new ways to grow skin cells in the lab. Epidermal stem cells are currently cultivated on a layer of cells from rodents, called feeder cells. These cell culture conditions have been proved safe, but it would be preferable to avoid using animal products when cultivating cells that will be transplanted into patients. So, researchers are searching for effective cell culture conditions that will not require the use of rodent cells.

Scientists are also working to treat genetic diseases affecting the skin. Since skin stem cells can be cultivated in laboratories, researchers can genetically modify the cells, for example by inserting a missing gene. The correctly modified cells can be selected, grown and multiplied in the lab, then transplanted back onto the patient. Epidermolysis Bullosa is one example of a genetic skin disease, where patients can benefit from this approach. Work is underway to test the technique.

Stem cells explained: What are they, and how do they work?

By admin

Stem cells explained: What are they, and how do they work?

What are stem cells and how do they work?

There are three types of stem cells. Each has potential for medical research and clinical applications based on its unique properties.

Peter Hoey, Special To The Chronicle

Stem cells are the building blocks of the human body. At the start of life, they divide over and over again to create a full person from an embryo. As we age, they replenish cells in our blood, bone, skin and organs. Stem cells could be powerful tools in treating injury and illness.

Embryonic Stem Cells

The first cells to form after a sperm fertilizes an egg.

Blank slate cells: can become every other kind of cell in the body.

Can divide and multiply endlessly.

Controversial in medicine because embryos must be destroyed to obtain stem cells.

Adult Stem Cells

Mature stem cells that replenish blood, skin, gut and some other cells.

In some cases, can replace cells damaged by illness or injury.

Limited ability to become other types of cells.

Limited ability to divide and multiply.

Induced-pluripotent Stem Cells

Adult cells that are reprogrammed to look and act like embryonic stem cells.

Can be made from skin, blood and other adult cells.

From their embryonic-like state, can be further altered to become any other type of cell.

Good potential use in medicine, but still a new area of research.

Embryonic

What are they?

Embryonic stem cells are the starter cells of the human body. They are undifferentiated, which means they have not matured and specialized, and they are able to become any other kind of cell in the body.

In embryos, these cells multiply and differentiate to become organs, bones and muscles. In the laboratory, they can be multiplied to create stem cell lines for study or for therapy.

Scientists harvest embryonic stem cells from three- to five-day-old embryos donated by people who have gone through in-vitro fertilization. Scientists isolated the first human embryonic stem cells in 1998.

What makes them different from other stem cells?

These are the only stem cells that naturally are able to become any other cell type and to multiply endlessly. Under the right circumstances in a lab, they can be nudged to become specific cell types.

Why do these characteristics give these cells medical potential?

Because of their ability to differentiate and multiply, embryonic stem cells long were thought to be the most powerful, and thus have the most potential for treating injury and disease. If scientists are able to control how they differentiate and how often, embryonic stem cells could be used to replace any damaged part of the body from missing insulin-making cells in people with Type 1 diabetes to brain cells lost in Parkinsons disease or skin cells scarred by burns.

What are the limitations of these therapies?

Many people have ethical problems using human embryos for scientific study. Also, embryonic stem cells ability to replicate endlessly means they may develop mutations that can interfere with their growth or allow them to keep dividing to the point of causing harm. Finding the right medical applications for embryonic stem cells is challenging.

Adult

What are they?

Adult stem cells are so-named because they are more mature than embryonic stem cells, though they dont necessarily have to come from adults. Their maturity means that they are limited in their ability to differentiate. Pockets of adult stem cells are found in many of our organs and they replenish cells in the organs in which they reside. Types of adult stem cells include:

Hematopoietic

Found in bone marrow and umbilical cord blood, they become blood and immune cells. They are the only stem cells approved by the FDA for therapy, for treatment of certain blood cancers.

Mesenchymal

These cells are found throughout the body, including in bone marrow, fat tissue and organs. They turn into the connective tissue found throughout the body, though the specific cell they become is related to the organ in which theyre located. These stem cells may decrease inflammation.

Fetal

Stem cells from fetuses are more mature, and therefore less able to differentiate, than embryonic stem cells, but they may be more multipurpose than other adult stem cells. For example, neural stem cells from fetal brain tissue can become several kinds of neurons, but neural stem cells from the adult brain are rare and have very limited ability to differentiate.

What makes them different from other stem cells?

Adult stem cells are limited in their abilities. They can only become certain types of cells they are called multi-potent, instead of pluripotent, for that reason and there is a limit to how often they can divide.

Why do these characteristics give these cells medical potential?

Adult stem cells are less powerful than embryonic, but they are easier to use, since all humans have their own supply of these cells. They may be useful for reducing inflammation.

What are the limitations of these therapies?

Its unclear how useful these stem cells could be given their limited abilities. Though the idea of tapping into a persons own source of adult stem cells and using them for treatment is appealing, these cells cannot repair serious injuries or replace cells lost to disease, like neurons or insulin-producing cells.

Induced-pluripotent

What are they?

Induced-pluripotent stem (IPS) cells are adult cells often skin or blood cells that have been taken from an individual and reprogrammed in a lab to become like embryonic stem cells. Then, like embryonic stem cells, they can be developed into any other type of cell. So a skin cell could be turned into an embryonic-like cell and then further turned into a heart cell.

What makes them different from other stem cells?

Like embryonic stem cells, except they are manufactured in a lab. And since they come from an individual, they are an exact match to that individual. Scientists are still studying whether IPS cells could be used interchangeably with embryonic stem cells.

Why do these characteristics give these cells medical potential?

They could be used to replace cell types lost to disease or injury. In addition, IPS cells can be used to study human diseases in Petri dishes or in animals. Scientists can take skin cells from a person with a genetic mutation, convert those cells to IPS cells, then study those cells as a living model of how the mutation functions.

What are the limitations of these therapies?

Making IPS cells can be a time- and resource-consuming process. But mostly, IPS cells have the same limits as embryonic stem cells.

Grow Stem Cells with Fasting – The Healing Miracle

By admin

New research from the University of Southern California has come to light that fasting as little as eight (8) days a year could deliver significant health benefits, especially when it comes to stem cells.

Believe it or not, fasting two to four days at a time (every six months) causes stem cells to awaken from their normal dormant state, and start regenerating.

Essentially, researchers discovered that fasting helped eliminate damaged and older cells, allowing new healthier cells to replace them completely, effectively renewing the immune system.

This is one of the first times any natural intervention has ever been shown to trigger this self-renewal.

Going a bit deeper In mice and humans, white blood cell counts were significantly lowered after long periods without food. These bodies are vital to the human immune system.

But, when their numbers decline to a critical point, pathways for hematopoietic stem cells were switched on. These cells manage the immune system and generate new blood.

When you starve, the system tries to save energy, and one of the things it can do to save energy is to recycle a lot of the immune cells that are not needed, especially those that may be damaged, Valter Longo of the USC Davis School of Gerontology, said.

Fasting for an extended period of time (up to 48 to 96 hours) changes the human body to consume fat reserves, glucose (sugar), and ketones. Unhealthy white blood cells are also broken down, so that in part, their components can be reused for new, thriving cells.

This is considered to be a cell recycling of sorts.

After a period of fasting, the bodys immune system will generate new blood cells when nutrients begin flowing back into the body.

The main point of interest in this study at USC, they were committed to knowing what drives body systems to rebuild the cells.

To go further into the science a bit

The study found that Protein kinase A, an enzyme known to inhibit cell regeneration, was reduced in the systems of people who are fasting. Concentrations of a growth-factor hormone called IGF-1 were also lowered in those who have not eaten in days.

Important note: you will want to be careful if you decide to fast on only water for extended periods of time. To protect yourself, fasting for two to four days at a time should be done under medical supervision.

Another approach to fasting which has produced beneficial results is time restricted eating or intermittent fasting. This form of fasting involves eating in an 8 hour window and not eating during the remaining 16 hours.

This could be during a span from noon to 8:00 pm or 9:00 am to 5:00 pm. This time period will be completely up to you, just as long as you limit your intake to a single eight hour duration.

Youre not limited to the amount of water, and intermittent fasting is growing in popularity but is still considered a secret in the stem cell community.

Fasting has been a widely used approach for generations going back to early civilization, but either as a survival, ritualistic, or weight loss tactic.

But now, we have the research to support that fasting is an incredibly powerful stem cell boosting secret that can return powerful results.

After this study (and others) surfaced, we became inspired to see what other natural alternative secrets are out there.

In the end, we were able to gather and expand on 7 Secrets PROVEN to Grow More Stem Cells.

Macquarie Stem Cells Treatment – Sydney, Melbourne, Perth …

By admin

After 20 years in general and cosmetic medicine, in 2004 Dr Ralph Bright encountered his first experience with biological medicine. Dr. Bright performed a cosmetic fat transfer into a patients leg to improve the appearance of a split skin graft after having a cancerous growth removed.Typically, you will need to transfer the fat a few times to achieve the desired shape.

Thats when Dr. Bright read the work of Patricia Zuk which was published in 2001. He had come to understand, body fat actually contains numerous different cell lines that can help repair damage in your body.

Moving forward to 2008, Dr Bright was invited to teach veterinarians how to perform liposuction on dogs. This struck him as odd Why do dogs need liposuction?After signing a confidentiality waiver they showed Dr Bright a dog who looked perfectly healthy and commented, just 6 months ago this dog could not get off the ground because they were riddled with arthritis. The veterinarians were using the dogs own body fat to treat the dogs arthritis.

Later, in 2008 one of Dr Brights patients repetitively requestedI need this treatment for my arthritis, I need you to try it.After a lot of research, in 2009 Dr Bright agreed to treat her. This was Dr Brights very first patient for this process.In fact it was the very first patient to ever receive treatment for their osteoarthritis using their own body fat in Australia.

That patient responded phenomenally well, so we treated a series of 6 patients and published these results in the medical journals. These results prompted Dr. Bright to start the new medical company we got to know as Macquarie Stem Cells.

Fast forward 10 years, Macquarie Stem Cells now has multiple doctors, nurses, cell biologists, cell technicians, consultants with a team of allied health professionals. Our results are significantly better, with higher success rates for our patients receiving treatment.We also perform a significant amount of research using our own private funding, including an upcoming placebo controlled clinical trial.

Thats the thing about medicine and innovation, its scary and its risky but, at the end of the day someone has to get up and lead the way. This is our way of giving back to the community.

Bone marrow failure occurs in individuals who produce an insufficient amount of red blood cells, white blood cells or platelets. Red blood cells transport oxygen to be distributed throughout the bodys tissue. White blood cells fight off infections that enter the body. Bone marrow also contains platelets, which trigger clotting, and thus help stop the blood flow when a wound occurs. [1]

Bone marrow failure is associated with three types of diseases, Fanconi anemia (FA), dyskeratosis congenita, and aplastic anemia. Fanconi anemia is an inherited blood disorder due to abnormal breakages in DNA genes. It is linked to hyperpigmentation, which is the darkening of an area of skin or nails caused by increased melanin. According to Histopathology, However, in about 30% of FA patients no physical abnormalities are found.[2] Dyskeratosis congenita often affects multiple parts of the body. Individuals with this disorder usually show changes in skin pigmentations, unusual fingernail growth, and mucosa leukoplakia; the inner part of the mouth is encased with white patches that may never resolve.[2] Aplastic anemia happens when bone marrow doesnt produce enough new blood cells throughout the body. Aplastic anemia is an acquired autoimmune disease, which occurs when the immune system mistakenly attacks and destroys healthy body tissue.[3]

Bone marrow failure in both children and adults can be either inherited or acquired. Inherited bone marrow failure is often the cause in young children, while older children and adults may acquire the disease later in life.[4] A maturation defect in genes is a common cause of inherited bone marrow failure.[5] The most common cause of acquired bone marrow failure is aplastic anemia.[5] Working with chemicals such as benzene could be a factor in causing the illness. Other factors include radiation or chemotherapy treatments, and immune system problems.

The two most common signs and symptoms of bone marrow failure are bleeding and bruising. Blood may be seen throughout the gums, nose or the skin, and tend to last longer than normal. Children have a bigger chance of seeing blood in their urine or stools, which results in digestive problems with an unpleasant scent. Individuals with this condition may also encounter tooth loss or tooth decay. Chronic fatigue, shortness of breath, and recurrent colds can also be symptoms of bone marrow failure.[6]

The type of treatment depends on the severity of the patients bone marrow failure disease. Blood transfusion is one treatment. Blood is collected from volunteer donors who agree to let doctors draw blood stem cells from their blood or bone marrow for transplantation.[7] Blood that is taken straight from collected blood stem cells is known as peripheral blood stem cell donation. A peripheral stem cell donor must have the same blood type as the patient receiving the blood cells. Once the stem cells are in the patients body through an IV, the cells mature and become blood cells. Before donation, a drug is injected into the donor, which increases the number of stem cells into their body. Feeling cold and lightheaded, having numbness around the mouth and cramping in the hands are common symptoms during the donation process. After the donation, the amount of time for recovery varies for every donor, But most stem cell donors are able to return to their usual activities within a few days to a week after donation.[7]
