Using blobs of skin cells from frog embryos, scientists have grown creatures unlike anything else on Earth, a new study reports. These microscopic living machines can swim, sweep up debris and heal themselves after a gash.

Scientists often strive to understand the world as it exists, says Jacob Foster, a collective intelligence researcher at UCLA not involved with this research. But the new study, published March 31 in Science Robotics, is part of a liberating moment in the history of science, Foster says. A reorientation towards what is possible.

In a way, the bots were self-made. Scientists removed small clumps of skin stem cells from frog embryos, to see what these cells would do on their own. Separated from their usual spots in a growing frog embryo, the cells organized themselves into balls and grew. About three days later, the clusters, called xenobots, began to swim.

Normally, hairlike structures called cilia on frog skin repel pathogens and spread mucus around. But on the xenobots, cilia allowed them to motor around. That surprising development is a great example of life reusing whats at hand, says study coauthor Michael Levin, a biologist at Tufts University in Medford, Mass.

And that process happens fast. This isnt some sort of effect where evolution has found a new use over hundreds of thousands of years, Levin says. This happens in front of your eyes within two or three days.

Xenobots have no nerve cells and no brains. Yet xenobots each about half a millimeter wide can swim through very thin tubes and traverse curvy mazes. When put into an arena littered with small particles of iron oxide, the xenobots can sweep the debris into piles. Xenobots can even heal themselves; after being cut, the bots zipper themselves back into their spherical shapes.

Scientists are still working out the basics of xenobot life. The creatures can live for about 10 days without food. When fed sugar, xenobots can live longer (though they dont keep growing). Weve grown them for over four months in the lab, says study coauthor Doug Blackiston, also at Tufts. They do really interesting things if you grow them, including forming strange balloon-like shapes.

Its not yet clear what sorts of jobs these xenobots might do, if any. Cleaning up waterways, arteries or other small spaces comes to mind, the researchers say. More broadly, these organisms may hold lessons about how bodies are built, Levin says.

With the advent of new organisms comes ethical issues, cautions Kobi Leins, a digital ethics researcher at the University of Melbourne in Australia. Scientists like to make things, and dont necessarily think about what the repercussions are, she says. More conversations about unintended consequences are needed, she says.

Levin agrees. The small xenobots are fascinating in their own rights, he says, but they raise bigger questions, and bigger possibilities. Its finding a whole galaxy of weird new things.

Frog skin cells turned themselves into living machines - Science News Magazine

Last year, something new was grafted to the tree of life.

Somewhere between a living organism and a robot, these tiny, living machines were created from clumps of stem cells from the African clawed frog. Stem cells from the heart gave them muscle, while skin stem cells provided structure.

Dubbed "Xenobots" (after the frog's scientific name not, alas, xenomorphs), their creators found that the living machines that could complete simple tasks in Petri dishes, as Freethink's Amanda Winkler explained last year.

Those same researchers, from Tufts and the University of Vermont, have now developed a second iteration, Xenobots 2.0, if you will, which can "self-assemble a body from single cells, do not require muscle cells to move, and even demonstrate the capability of recordable memory," as Tufts Now explains.

These Xenobots are also faster, can make their way through more complex environments, live longer than their predecessors, work in concert, and heal themselves.

Yeah, that sounds a lot like the T-1000 to me, too.

First generation Xenobots were constructed with a "top-down" approach, as Tufts put it. The researchers manually placed and surgically sculpted the heart and skin cells to form tiny biological robots in a variety of shapes.

Their shapes chosen with the help of a digital Xenobots simulator then impacted their various movements.

The original Xenobots were capable of "crawling, traveling in circles, moving small objects or even joining with other organic bots to collectively perform tasks," Winkler reported.

But to create Xenobots 2.0, the researchers utilized a "bottom up" approach, published in the journal Science Robotics.

Rather than crafting the frog heart and stem cells, the researchers simply scraped off some skin stem cells from frog embryos. Left to their own devices, the cells glommed together into spheroids on their own.

They could survive for 10 days without food and even grow if some sugar's in the mix.

"We've grown them for over four months in the lab," Tufts' Doug Blackiston, study coauthor, told Science News. "They do really interesting things if you grow them," including forming new, balloon-like shapes.

Some of the cells adapted to grow cilia a few days in. Usually used by cells to push away pathogens and ensure a nice coating of protective mucus, the Xenobots used their cilia to move around, eliminating the need for heart stem cells.

It's an example of life's remarkable plasticity, the researchers say.

"In a frog embryo, cells cooperate to create a tadpole. Here, removed from that context, we see that cells can re-purpose their genetically encoded hardware, like cilia, for new functions such as locomotion," Michael Levin, professor of biology and director of Tufts' Allen Discovery Center and study corresponding author told Tufts Now.

"It is amazing that cells can spontaneously take on new roles and create new body plans and behaviors without long periods of evolutionary selection for those features."

Along with those new body plans came new abilities. Xenobots 2.0 can move around just like the first iteration did, but they are faster than what the researchers constructed. They're also better at sweeping up junk a swarm of them can round up iron oxide particles in a Petri dish and they can coat flat surfaces and shimmy through narrow capillaries.

Because they are biological, the Xenobots could also heal themselves, forming back together after injury even recovering from full-length lacerations halfway through their "bodies" in just 5 minutes.

"In a frog embryo, cells cooperate to create a tadpole. Here, removed from that context, we see that cells can re-purpose their genetically encoded hardware, like cilia, for new functions such as locomotion."

Just like before, the Tufts team turned to computer simulations to tease out the best Xenobot layouts. Researchers at the University of Vermont did the data crunching, using the Vermont Advanced Computing Core's supercomputer cluster, called Deep Green.

Deep Green comes in because "it's not at all obvious for people what a successful design should look like," UVM computer scientist and robotics expert Josh Bongard told Tufts Now. "That's where the supercomputer comes in and searches over the space of all possible Xenobot swarms to find the swarm that does the job best."

The hope is that eventually Xenobots will be able to perform tasks like clearing microplastics from the ocean, or decontaminating soil.

Performing those jobs would be a hell of a lot easier with the ability to retain and access memory for guiding their actions something the original Xenobots lacked. This time around, the researchers gave them the ability to hold on to one piece of information.

The researchers injected the frog stem cells with mRNA carrying the instructions for a protein called EosFP. This protein normally glows green, but when exposed to a specific wavelength of light, it turns red instead.

Armed with their little running light, the Xenobots could now keep a record of being exposed to certain wavelengths of blue light in their environment. Further work could potentially allow them to keep track of multiple variables, or even alter their behaviors accordingly.

"When we bring in more capabilities to the bots, we can use the computer simulations to design them with more complex behaviors and the ability to carry out more elaborate tasks," Bongard said. "We could potentially design them not only to report conditions in their environment but also to modify and repair conditions in their environment."

The researchers' original work already opened questions of what, exactly, Xenobots are. Are they lifeforms? Robots, but made of biological material, in lieu of nuts and bolts?

As you can imagine, these improved iterations which organize on their own are provoking more of the same.

Tel Aviv University evolutionary biologist Eva Jablonka, who is unaffiliated with the work, told Quanta Magazine that she considers them a new form of life "defined by what it does rather than to what it belongs developmentally and evolutionarily."

Armed with a special protein that changes color from green to red, the next generation Xenobots could keep a simple record of their exposure to blue light. Credit: Doug Blackiston & Emma Lederer, Tufts University

University of Melbourne digital ethics researcher Kobi Leins believes new ethical issues arise with the creation of new forms of life. "Scientists like to make things, and don't necessarily think about what the repercussions are," she told Science News.

(For what it's worth, Levin agrees, telling Science News the questions raised by the Xenobots are like "finding a whole galaxy of weird new things.")

Levin hopes that within that galaxy, the Xenobots will do more than perform tasks: they may help us understand how biological life itself develops.

The Next Generation of Living Machines: Xenobots 2.0 - Freethink

Newswise March 30, 2021 As cancer survival rates improve, more people are living with the aftereffects of cancer treatment. For some patients, these issues include chronic radiation-induced skin injury which can lead to potentially severe cosmetic and functional problems.

Recent studies suggest a promising new approach in these cases, using fat grafting procedures to unleash the healing and regenerative power of the body's natural adipose stem cells (ASCs). "Preliminary evidence suggests that fat grafting can make skin feel and look healthier, restore lost soft tissue volume, and help alleviate pain and fibrosis in patients with radiation-induced skin injury after cancer treatment," says J. Peter Rubin, MD, MBA, FACS, American Society of Plastic Surgeons (ASPS) President-Elect and Chair of the Department of Plastic Surgery at University of Pittsburgh Medical Center. He is one of the authors of a new review of the clinical evidence on fat grafting for radiation-induced skin and soft tissue injury.

"But while promising, available research has some key weaknesses that make it difficult for us to determine the true benefits of fat grafting right now," Dr. Rubin adds. The review appears in the April issue of Plastic and Reconstructive Surgery, the official medical journal of the ASPS.

More than half of patients diagnosed with cancer receive radiation therapy. Because skin cells turn over rapidly, they are exquisitely sensitive to the damaging effects of radiation. In the first few months after treatment, many patients develop acute radiation injury with skin inflammation, peeling, swelling, pain and itching. In most cases, symptoms resolve over time. However, if inflammation continues, radiation-induced skin injury can become a chronic problem leading to tight, stiff skin (fibrosis) with a risk of poor wound healing, ulcers, and tissue loss.

Fat grafting procedures transferring the patient's own fat cells from one part of the body to another have become widely used in many cosmetic and reconstructive plastic surgery procedures. In their review, Dr. Rubin and colleagues round up promising research on fat grafting for patients with radiation-induced skin injury.

In studies of breast cancer patients, fat grafting procedures have reduced pain and other symptoms of radiation-induced skin injury backed up by more-normal cellular appearance of skin cells under the microscope. In other studies, fat grafting has led to reduced risks and better outcomes of breast reconstruction after mastectomy.

For patients with radiation-induced skin injury after treatment for head and neck cancer, fat grafting has led to improvements in voice, breathing, swallowing, and movement. Good outcomes have also been reported in patients with radiation-induced skin injury in the area around the eye or in the limbs.

"The good news is fat grafting has the potential to really help patients with discomfort and disability caused by radiation-induced skin damage," according to Dr. Rubin. While research is ongoing, the benefits of fat grafting seem to result from the wide-ranging effects of ASCs including anti-scarring, antioxidant, immune-modulating, regenerative, and other actions.

"However," he adds, "the available evidence has a lot of shortcomings, including small sample sizes, lower-quality research designs, and a lack of comparison groups." Variations in fat cell collection and processing, as well as the timing and "dose" of fat grafting, make it difficult to compare results between studies. There are also unanswered questions regarding potential risks related to ASC injection and concerns that fat grafting might affect cancer follow-up.

The reviewers outline some steps for further research to clarify the benefits of fat grafting for radiation-induced skin and soft issue injury, including approaches to clinical assessment and imaging studies, testing of skin biomechanics and circulation, and cellular-level analyses. For all of these outcomes, standardized measures are needed to achieve more comparable results between studies.

"We hope our review will inform efforts to establish the benefits of specific types of fat grafting procedures in specific groups of patients," says Dr. Rubin. "To do that, we'll need studies including larger numbers of patients, adequate control groups, and consistent use of objective outcome measures."

Fat grafting shows promise for cancer patients with radiation-induced skin injury - Newswise

The Augustinus Bader story hasbecome a beauty legend. Professor Bader, one of the worlds leading stem-cell experts, makes a groundbreaking wound gel that rehabilitates the skin of burns victims,without the need for grafts or scarring. At a dinner hosted by Robert Friedland, the self-made billionaire and long-time mentor to Steve Jobs, Bader meets Charles Rosier, a young French financier. They are kicking around ideas forfunding the necessary clinical trials forthe product, which would likely run intothetens of millions. Pharmaceutical companies arent interested because most burns victims are in emerging countries, where the market for sophisticated healing products is negligible.

Rosier has a flash of inspiration: couldBader use what he knows about wound healing to make an anti-ageing cream? Yes, answers Bader unhesitatingly. Two years and much cajoling later, the professor makes a prototype skincare cream, and pretty soon anyone who has ever had more than a passing interest in face cream is talking about it.

According to Deloitte, as many as 90per cent of beauty launches fail within ayear. By contrast, the Augustinus Bader skincare brand has grown from a turnover of $7m in 2018 to $70m in 2020. It has also shattered traditional conventions of luxury skincare along the way. For a start, the company launched with just two face products, The Cream (fornormal/oily skin) and The Rich Cream (dry skin) and insisted that apart from cleanser andSPF theyre all you need to use. No eye cream, no neck cream, no serum underneath, no primer ontop just one cream, and a very specific two pumps at that. This was intriguing. Most luxury-skincare brands (the creams retail at205 each) dont just sell you a dream they sell you a regime.

Charles Rosier believes that their inexperience in the beauty industry helpedat first. If Id known how complex and competitive the industry is, maybe Iwouldnt have had so much passion for it. But because I had seen what Augustinuss science could do, I was truly convinced thathe could create a product that was new, disruptive and of higher quality than whatever else was in the market.

As it turned out, it was. Celebrities normally paid handsomely to endorse beauty brands were not only recommending the Augustinus Bader cream unprompted butinvesting in the company too (Courteney Cox, Melanie Griffith and Carla Bruni to note). Usually cynical beauty editors discussed it with the fervour of addicts (myself included). And in February, a panel of more than 300 industry experts voted The Cream and The Rich Cream as Womens Wear Dailys Greatest Skincare Product ofAll Time (Crme de la Mer, launched in 1965, took second place and Este Lauder Advanced Night Repair, from 1982, took third), neatly capping off a pleasing statistic of 36 awards in 36 months.

Bader a softly spoken, bow tie-wearing 61-year-old German is both asthrilled and bemused by the brands success as youd hope. Before making the face cream, he says, he had never used a skincare product in his life. But he likes the fact that now, when he uses the cream before shaving, he no longer cuts himself. It would never have occurred to him to have created a cleanse/tone/moisturise-type regime. Beauty is always from inside, he says. You dont need a routine, as many people have been used to. The idea is that just after washing your face, you use The Cream or The Rich Cream. Everything is in that one product.

Before making the face cream, Bader had never used a skincare product inhis life

It would be tempting to paint Bader asthe sneery scientist, dabbling with the beauty world as a means to an end(close to10per cent of the brands profits in 201920 went to wound-healing research and other charities). The opposite is true: what finally convinced him to embark onthe project was his patients reaction tohisearly prototype: When I gave theproduct to patients with diabetic wounds, their skin became healthier-looking and stronger, and I could see how happy it made them...so for me, even though it was just a skincare product, it developed a kind of medical meaning.

Also subversive is the brandsconspicuous lack ofmiracle ingredients. Baderswork is guided by theprinciple that your skin contains all it needs already its the communication between thecells thats important, notapplying endlessnew ingredients that your skin doesnt recognise. Conventional medicine very often tries to helpby treating symptoms, but what the patientreally wants is a healing process, he says. The creams themselves contain a complex called TCF8, which hesays is mainly made out of vitamins, amino acids and lipid structures.

According to Charles Rosier, Bader isprobably the person in the team who is strictest about only using gentle ingredients which means the brand is able to satisfy the current appetite for clean skincare too. Thats why theres no SPF; because Bader is vehemently opposed to chemical sun filters and has so far found it hard to make sufficiently premium-feeling sun protection without them. And, says Bader, a little bit of sun is good for your skin as is a little bit of stress (and carrot juice: he says that people who eat a lot of carrots generally have good skin).

Last month the brand also launched avegan version of The Rich Cream, with original ingredients such as beeswax and lanolin removed and a slightly upgraded formulation. It has the same rich texture and the same uncanny ability which fans can eulogise about for hours to hug your skin within seconds of applying.

But is it getting harder to avoid the pull of the beauty mainstream? Some devotees have taken a recent spate of new launches to mean that the brand is moving away from its original one cream is all you need philosophy, and that as a result has lost some of its outsider charm. In the second half of 2020, launches came thick and fast: theres now anEssence, Face Oil, Cleansing Balm, Cleansing Gel and Lip Balm, plus body oils and lotions.

Rosier points outthat most of their competitors have around 200 products and that last years bottleneck of launches was largely due to hold-ups in the lab, as well as Covid-19. Perhaps our philosophy has switched a little from Well give you one cream to Wellgive you the essential basics of a skincare routine, he concedes. Well never do 20 serums, but well do products where we feel they can be better than otherthings that exist in the market, and allow you to have an Augustinus Bader routine and not have to mix our products with other brands.

Given how feverish the current Baderobsession is, it seems unlikely thatcustomers would need much convincingnot to mix other brands products into their routines. What isdebatable is how long this brand can remain a disrupter. Ever the renegade, Bader is less interested in being a beauty outsider than encouraging the rest of the field toraise its game.

This new beauty side of mywork is interesting because, ultimately, healthy skin contributes to beauty and for me, thats notsomething superficial, its something absolutely relevant to all the work that I do, including the medical research. In a way, Ihope that perhaps what we can do is be a little bit game-changing about what a skincare product may want to achieve. And that, to me, sounds like real hope in a jar.

Augustinus Bader and the making of a $70m phenomenon - Financial Times

Published on April 2, 2021

Recently, a 43-year-old man was presented at Fortis Hospital, Noida, complaining of severe back pain. Upon investigation, it was found that he was suffering from a rare disease, multiple myeloma which is a type of cancer that forms in the white blood cells or plasma cells. Here cancerous plasma cells accumulate in the bone marrow and crowd around the healthy blood cell that help in fighting infections by building antibodies, this puts the patients life at high risk. He therefore urgently required a Bone Marrow Transplant (BMT). Dr Rahul Bhargava, Director and Head, Hematology and Bone Marrow Transplant, Fortis Hospital, Noida and his team took a timely decision to go ahead with BMT to save his life.

A bone marrow transplant is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Bone marrow is the soft, fatty tissue inside your bones. The bone marrow produces blood cells. Stem cells are immature cells in the bone marrow that give rise to different blood cells. Bone marrow transplant has now revolutionised. It is like a peripheral blood stem cell transplant, meaning, it is just like a blood transfusion (like platelet apheresis) which does not require any anesthesia.

Upon further investigation it was revealed that chemotherapy was required before BMT. Following the chemotherapy, on the 10thday of admission the team of doctors engulfed stem cells in the patients body which provided the body with a new source of healthy cells. Safe hospital environment and the doctors expertise in the area ensured that the BMT was done smoothly, without any complications and within 15 days the patient had been discharged. Usually, a patient takes 25-30 days to recover but here, due to patients will to recover and the facilities provided to him in the hospital he recovered at a faster pace.

Dr Rahul Bhargava, Director and Head, Hematology and Bone Marrow Transplant, Fortis Hospital, Noida, said,The case was complicated as the patient was suffering from high-risk multiple myeloma, which is a rare form of cancer. We took the necessary precautions and performed chemotherapy first to which he responded well and post that a Bone Marrow Transplant (BMT) was performed successfully. The process was smooth, and no complications arose during the same. We request patients to not fear BMT and undergo the process when required.

Talking about the clinical excellence at Fortis Hospital, NOIDA,Mr Hardeep Singh, Zonal Director, Fortis Hospital, Noidasaid, The team at Fortis Hospital, Noida try their best to save lives and do not give up even if there is 1% chance of survival. The patient was suffering from high-risk multiple myeloma for which immediate bone marrow transplant was required. The case was managed extremely well and with a lot of patience by Dr Rahul Bhargava and his team. I applaud the team of doctors for their continued commitment towards clinical expertise and patient care.

Timely Bone Marrow Transplant by Fortis gives new lease of life to a patient with Multiple Myeloma - APN News

Advances in the treatment of patients with leukemias and lymphomas have led to a significant improvement in survival, which has increased the need for bone marrow transplant as a later-line therapy, said Mehrdad Abedi, MD, who added that Orca-T, a high precision cell therapy, confers significant antitumor activity, minimizes the incidence of acute and chronic graft-vs-host disease (GVHD), and causes less adverse effects (AEs) compared with standard bone marrow transplant among these patients.

There is a lot of research [ongoing]; the holy grail of research is trying to figure out whether we can separate the graft-vs-leukemia or graft-vs-lymphoma effect from GVHD, said Abedi. [The Orca-T trial] is basically looking at the past 10 years of research in this area to try to identify the cells that are good from those that are bad.

During the 2021 Transplantation and Cellular Therapy (TCT) Meetings, findings from an analysis of 2 studies demonstrated a significant reduction in cases of GVHD, a higher GVHD relapse-free survival rate, and a lack of treatment-related mortalities with Orca-T when historically compared with hematopoietic stem cell transplant (HSCT).

Additionally, the median time to neutrophil engraftment, median time to platelet engraftment, and median time from day 0 to hospital discharge was shortened with Orca-T compared with HSCT.

In an interview with OncLive during the 2021 TCT Meetings, Abedi, a professor of cancer, hematology/oncology, and internal medicine in the Department of Internal Medicine, Division of Hematology and Oncology at the UC Davis Comprehensive Cancer Center, discussed the challenges of standard transplant, how Orca-T could overcome some of those limitations, and the potential future of transplant in hematologic malignancies.

Abedi: HSCT has been around for more than 50 years in one form or another. It has been used mostly for patients with blood cancers, [such as] leukemia and lymphoma. Allogeneic bone marrow transplants, where we use cells from a donor, are very effective. [They are associated with] a very high response rate for patients who have no other options and whose disease is going to [recur] without transplant.

The problem [with allogeneic bone marrow transplant] is that it [is associated with] AEs. When we give donor cells to patients after high-dose chemotherapy, [which is given] so that the patients body doesnt reject [the cells], even though the cells are a match for the patient, they can still [develop] severe GVHD.

The acute form of GVHD can be life threatening, whereas the chronic form can become a nuisance for the rest of a patients life. A lot of patients suffer [from GVHD] to the point where they regret going through transplant. Fortunately, that is not everybody, but it is still a problem that needs to be solved and an unmet need for the field.

This research has been focused on [the question of]: Are there specific cells in the graft we give to the patients immune cells that can cause GVHD? Can we separate those cells from those that are responsible for causing graft-vs-leukemia effects?

Basically, Orca Bio approached UC Davis a few years ago to [start] collaborative research with our Good Manufacturing Practice [GMP] facility and to produce these products.

Each graft of [the Orca-T] product has stem cells and immune cells in it. The stem cells are what we need to maintain the graft and [allow the product to] stay in the patient for a long time. The immune cells are the ones that can cause graft-vs-leukemia [effects], which is what we want.

From the work that Robert Negrin, [MD] at Stanford University and many other investigators [did], it is very clear that there is a population of T cells called T-regulatory cells that can prevent GVHD. There are other populations, such as the nave T cells or conventional T cells that can cause GVHD. It looks like a smaller number of [those cells] may actually be helpful; they can cause graft-vs-leukemia, but not GVHD.

The graft is basically designed so that we can give stem cells, but they get rid of a lot of conventional T cells that can cause rapid GVHD. [The graft provides] a small amount of conventional T cells that can cause graft-vs-leukemia effects, as well as the regulatory T cells that can prevent GVHD. UC Davis got involved [with this work] because we have a very robust GMP facility. We helped Orca Bio design these protocols and manufacture the cells. Now, [Orca Bio] has moved on to their own facility. I have been involved [with this research] for the past few years.

[We] havent looked at the QOL data, but there have been several short-term and long-term benefits so far that we have seen.

We give high-dose chemotherapy that can get rid of all [the patients] stem cells and leukemia or lymphoma cells. Then, we give the graft; however, after the graft is given, it takes a couple of weeks usually to engraft [before] new cells [develop]. In between, the patients are sick because of the effects of the chemotherapy; patients also have low blood counts.

[With Orca-T] we have seen that the engrafting [occurs] a little bit earlier. For everyday [sooner] the engraftment [occurs], there is less risk of complication and suffering for the patient. That has been a major difference [with Orca-T].

Also, we have noticed that patients in general are doing better [with Orca-T compared with traditional transplant]. When we give high-dose chemotherapy, it is the same whether the patient is on a clinical trial or not. They may still get sick [with Orca-T] because of the effects of chemotherapy.

However, there is also inflammation [that can occur] as the donor cells are trying to establish themselves in the body because some of them attack the body. That inflammation also adds to the problems with chemotherapy. We havent seen that inflammation [with Orca-T]. We have seen some effects from the chemotherapy, but because we dont have the inflammation, other AEs that we see with the standard of care arent seen with Orca-T.

In general, patients do better [with Orca-T vs standard of care], and that has been a universal experience with all of our patients who have gone through the trial so far.

[Patients] just look and feel better. When they are discharged, they are not as sick compared with patients [receiving] the standard of care.

With the standard of care, after we give the graft, we have to give patients a new medication to prevent GVHD because it is such a lethal problem. If we dont put patients on immunosuppressive medications to prevent GVHD, there is a very high chance that they get and die from GVHD. Those immunosuppressive medications are critical.

The way the Orca-T graft is designed is that we dont need as many of those [immunosuppressive] medications. For example, there is a medication called methotrexate that we give on days 1, 3, 6, and 11 after [standard] transplant. That medication can cause a lot of other AEs, such as mouth sores, delayed engraftment, and kidney [problems], that can make the patient miserable. With Orca-T, we dont have to [give methotrexate], which by itself is a huge improvement.

We do give immunosuppressive medications, such as tacrolimus [Envarsus XR] or sirolimus [Rapamune] to these patients, but we dont give 2 or 3 medications as we usually do with the standard of care. Less immunosuppressive medications mean probably less infection, but more importantly, less AEs. Thats [a factor that has made] a big difference in patient experience.

That is a very loaded question. There are a lot of new drugs coming, some of which are very targeted to treat leukemia or lymphoma. Thus far, we havent seen any curative [benefit] with those drugs, so in most situations, we will still need an allogeneic stem cell transplant for patients.

The exceptions [to that] were rare diseases, such as chronic myeloid leukemia [CML], where [an oral medication was approved] and we dont need to transplant patients. That is an example of a targeted treatment that may exclude [the need to] transplant patients. That would be great because transplant is not a trivial procedure and it has a lot of AEs.

However, [CML] is a very specific disease with 1 gene that causes the disease. In most leukemias and lymphomas, multiple genes are involved, so we dont think single-target treatments will get rid of the disease. We still think that allogeneic transplant will be around for a long time.

In fact, if you look at any center in the country, the volume of transplant has substantially increased over time because patients are living longer. Patients end up being able to go to a transplant vs before when many were dying in the middle of their treatment and not getting to transplant.

That being said, there are 2 directions [we can go in]. One is to try to decrease the AEs associated with transplant. This [Orca-T cell therapy] is very effective [in doing this] by targeting the graft-vs-leukemia effect and preventing GVHD. The second direction is to use these allogeneic cells to specifically target the tumor cells. That is why gene modifications, CAR T-cell therapies, and other approaches are coming. They still use allogeneic cells from a donor, but now they are directing them to specifically go after tumor cells.

Large granular lymphocytic (LGL) leukemia is a kind of cancer that affects blood cells. The disease is rare: Only about 1,000 people per year are diagnosed with it. It affects men and women in roughly equal numbers, and most of those diagnosed are over 60 years old.

Heres what we know about this form of leukemia.

Your blood is made up of four different parts:

Some of your white blood cells are larger than the rest. These cells contain tiny granules that can be seen under a microscope.

In people with LGL leukemia, these large, granular white blood cells copy themselves until there are too many. The fact that the white blood cells (also called lymphocytes) replicate themselves is what makes this disorder a type of cancer.

Your blood contains two different types of lymphocytes: T-cells (T-LGL) and B-cells, which are also known as natural killer cells (NK-LGL). B-cells fight off invading bacteria and viruses. T-cells attack other cells in your body that have become harmful, like cancer cells.

When your T-cells are copying themselves too much, you have T-LGL leukemia. If your natural killer cells are replicating too much, you have NK-LGL leukemia.

Most cases of LGL leukemia are chronic and slow-growing, whether theyre NK-LGL or T-LGL. Only around 10 percent of all LGL cases are aggressive, fast-growing cells.

Researchers dont yet know what causes LGL leukemia. The disorder is associated with a genetic change or mutation, usually to the STAT3 and STAT5b genes.

Between 10 and 40 percent of people with LGL leukemia also have a history of autoimmune disorders. The immune disorder most often associated with LGL leukemia is rheumatoid arthritis (RA).

About 20 percent of those with LGL leukemia also have RA. So far, researchers have been unable to determine which disorder began first.

Most people who are diagnosed with LGL leukemia will experience some of these symptoms:

A healthcare professional may look for other symptoms, too, including:

You should contact your doctor and seek treatment if youre having recurring infections, especially if you have a fever that doesnt go away or you have other infection symptoms, such as swelling or sores, that arent getting better.

To find out if you have LGL leukemia, a healthcare professional will analyze a sample of your blood. Your doctor may also take a sample of your bone marrow, often from your hip area, to look for abnormal cells.

To determine which type of LGL leukemia you have, your doctor could use a laser technology called flow cytometry to identify whether T-cells or NK-cells are replicating too much.

Most cases of LGL leukemia are slow growing. Doctors sometimes take a wait-and-watch approach to treatment.

You may not start treatment until tests or symptoms show that the condition has reached a certain level.

If tests show that your neutrophil levels have dropped too much, your doctor may start treatment at that time. Around 45 percent of people with this condition needed immediate treatment.

When treatment for LGL leukemia begins, it may or may not follow the same intensive course as other cancer treatments.

Most people will eventually need some combination of chemotherapy and immune-suppressing drug therapy. Your medications could include:

In some cases, treatment for LGL leukemia involves a bone marrow or stem cell transplant. Its also possible that your treatment could include removing your spleen, an organ in your abdomen that filters your blood and helps maintain your immune system.

Two to three times a year, you may need to visit a healthcare professional to have bloodwork done to monitor your health and the activity of your white blood cells.

While theres no cure for LGL leukemia, most cases progress very slowly, unlike other forms of leukemia. One study that followed 1,150 people with the disease found that they lived an average of 9 years after their diagnosis.

The more aggressive form of LGL leukemia doesnt respond well to treatment. Life expectancy is likely much shorter for those with this very rare subtype of LGL leukemia.

LGL leukemia is a rare type of cancer where large white blood cells copy themselves too much, making your body prone to frequent infections.

Most cases of LGL leukemia are slow-growing, so treatment might not be necessary at first.

Eventually, people with this condition might need a combination of chemotherapy and immunosuppressing medications to slow the growth of cancer cells. Theres no cure yet for LGL leukemia.

A small percentage of cases are a faster-growing type of leukemia that doesnt respond well to treatments. Life expectancy for this subtype is shorter than the slow-growing type.

LGL Leukemia: Overview, Symptoms, and Treatment - Healthline

One of the common research approaches to treating brain diseases such as Parkinsons disease (PD) and Alzheimers disease (AD) is using antibodies designed to clear the accumulated misfolded proteins implicated in the diseases. To date, these drug trials have not been particularly successful at improving the disease, even when they are effective at removing the proteins. A new theory hypothesizes that the antibodies are actually increasing the neuroinflammation associated with PD and AD, basically making the disease worse while removing the proteins.

Stuart Lipton, a researcher at Scripps Research Institute, recently published research suggesting that this may be exactly what is happening. They ran a series of in vitro assays and experiments in mice that had brain grafts of human-induced pluripotent stem cell (hiPSC)-derived microglia (hiMG). They found that the antibodies that target the misfolded proteins found in PD and AD trigger the NLRP3 inflammasome, which can lead to cell death.

Our findings provide a possible explanation for why antibody treatments have not yet succeeded against neurodegenerative diseases, said co-senior author Lipton, Step Family Foundation endowed chair in the department of molecular medicine and founding co-director of the Neurodegeneration New Medicines Center at Scripps Research.

The results were published in Proceedings of the National Academy of Sciences (PNAS).

The research started when Dorit Trudler, a postdoctorate researcher in Liptons lab, attempted to make microglia in the lab. Microglia are the innate immune cells in the brain, and it is a notoriously difficult task because the cells dont originate from the same type of stem cells in the bone marrow that generates the rest of the immune system.

Instead of coming from the bone marrow like B and T cells and macrophages, microglia are created from the yolk sac that embryos swim in during early development, then migrate from the sac to the brain. Trudler was able to turn human-derived stem cells to turn into a yolk sac-like structure, and from there, developed cells that were identical to microglia removed from humans based on the mRNA they expressed.

Lipton indicated, They match as closely as possible.

They then exposed these microglia to either alpha-synuclein, the misfolded protein identified in Parkinsons patients, and the microglia shot off inflammatory signals. And when they exposed the microglia to amyloid-beta, the hallmark of Alzheimers, the inflammation grew worse.

They then worked with biopharma companies to obtain antibodies that bind to either alpha-synuclein or amyloid-beta. Although Lipton is not saying which companies, it did say one of them was not Biogens aducanumab, which is up for approval or rejection for Alzheimers by June 7 by the U.S. Food and Drug Administration (FDA).

The surprising and potentially extremely important result was that although the antibodies successfully attached to their protein targets, it didnt help with inflammation. Rather than make things better, it actually made things worse, Lipton said.

And they further found in humanized mice with both human and mice microglia, that the pro-inflammatory response was unique to the human cells. This means that biopharma companies, in working with laboratory animals on therapeutic antibodies for these diseases, would not have seen this reaction. Although unclear yet why its causing inflammation, they are convinced the NLRP3 pathway is involved, although they dont have the exact mechanism worked out. Potentially, however, it might be possible to treat patients with a combination of the protein-clearing drugs and anti-inflammatories that block the NLRP3 pathway.

In an unrelated study, researchers at Massachusetts General Hospital utilized whole-genome sequencing (WGS) to identify rare genomic variants associated with AD. In doing so, they found 13 mutations, which establish new genetic links between AD and synaptic function. They believe it could help guide the development of new drugs for AD.

The first group of genes identified that were associated with AD involve the accumulation of amyloid-beta. The next 30 AD gene mutations identified were linked to chronic inflammation in the brain. Loss of synapses is the neurological change most closely linked with the severity of dementia in AD, but until now clear genetic association had not been identified.

Rudolph Tanzi, vice chair of Neurology and director of the hospitals Genetics and Aging Research Unit, said, It was always kind of surprising that whole-genome screens had not identified Alzheimers genes that are directly involved with synapses and neuroplasticity.

Tanzi went on to note that identifying less-common mutations that increase the risk for AD may provide critical information about the disease. Rare gene variants are the dark matter of the human genome, he said.

There are many of them, as it turns out. Of the three billion pairs of nucleotide bases in the human genome, about 5o to 60 million are gene variants and 77% are rare.

Exosomes are small extracellular vesicles produced by cells that contain lipids, messenger-RNA, micro-RNA, cytokines and proteins. Therapeutic benefits of using exosomes have been demonstrated in various disease models and may provide a valuable therapeutic tool for treating disease.

We are pleased to see that we have been granted an additional patent by the USPTO for our ThermoStem Program, said Lance Alstodt, the Companys CEO. Our comprehensive portfolio of patents under our ThermoStem Program continues to expand as we develop and protect intellectual property related to large and growing markets where brown adipocyte therapeutics can be applied. Im very proud of our team, driving towards the achievement of our stated goals. The advancement of our technology is a core, fundamental value driver of our Company. Our family of intellectual property coupled with our financial reporting progress are critical factors contributing to our growth strategy.

It is expected that the exosome diagnostic and therapeutic market will reach $368 million by 2022 as the development of research, clinical tools and therapeutics continues to grow in this emerging technology.

About BioRestorative Therapies, Inc.

BioRestorative Therapies, Inc. (www.biorestorative.com) develops therapeutic products using cell and tissue protocols, primarily involving adult stem cells. Our two core programs, as described below, relate to the treatment of disc/spine disease and metabolic disorders:

Disc/Spine Program (brtxDISC): Our lead cell therapy candidate, BRTX-100, is a product formulated from autologous (or a persons own) cultured mesenchymal stem cells collected from the patients bone marrow. We intend that the product will be used for the non-surgical treatment of painful lumbosacral disc disorders or as a complementary therapeutic to a surgical procedure. The BRTX-100 production process utilizes proprietary technology and involves collecting a patients bone marrow, isolating and culturing stem cells from the bone marrow and cryopreserving the cells. In an outpatient procedure, BRTX-100 is to be injected by a physician into the patients damaged disc. The treatment is intended for patients whose pain has not been alleviated by non-invasive procedures and who potentially face the prospect of surgery. We have received authorization from the Food and Drug Administration to commence a Phase 2 clinical trial using BRTX-100 to treat chronic lower back pain arising from degenerative disc disease.

Metabolic Program (ThermoStem): We are developing a cell-based therapy candidate to target obesity and metabolic disorders using brown adipose (fat) derived stem cells to generate brown adipose tissue (BAT). BAT is intended to mimic naturally occurring brown adipose depots that regulate metabolic homeostasis in humans. Initial preclinical research indicates that increased amounts of brown fat in animals may be responsible for additional caloric burning as well as reduced glucose and lipid levels. Researchers have found that people with higher levels of brown fat may have a reduced risk for obesity and diabetes.

BioRestorative Therapies Announces Notice of Allowance for a New Patent Application Related to its Off-the-Shelf ThermoStem Program - GlobeNewswire

What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and the very nature of matter.

Particle accelerators allow physicists to study subatomic particles by speeding them up in powerful magnetic fields and then tracing the interactions that result from collisions. By delving into the mysteries of the Universe, colliders have entered the Zeitgeist and tapped the wonders and fears of our age.

As far back as 2008, the Large Hadron Collider (LHC), operated by the European Organization for Nuclear Research (CERN), was charged with creating microscopic black holes that would allow physicists to detect extra dimensions. To many, this sounds like the plot of a disastrous science-fiction movie.

It came as no surprise when two people filed a lawsuit to stop the LHC from operating, lest it produce a black hole powerful enough to destroy the world. But physicists argued that the idea was absurd and the lawsuit was rejected.

Then, in 2012, the LHC detected the long-sought Higgs boson, a particle needed to explain how particles acquire mass. With that major accomplishment, the LHC entered popular culture; it was featured on the album cover of Super Collider (2013) by the heavy metal band Megadeth, and was a plot point in the US television series The Flash (2014-).

Yet, despite its accomplishments and glamour, the world of particle physics is so abstract that few understand its implications, meaning, or use. Unlike a NASA probe sent to Mars, CERNs research doesnt produce stunning, tangible images.

Instead, the study of particle physics is best described by chalkboard equations and squiggly lines called Feynman diagrams. Aage Bohr, the Nobel laureate whose father Niels invented the Bohr model of the atom, and his colleague Ole Ulfbeck have even gone as far as to deny the physical existence of subatomic particles as anything more than mathematical models.

Which returns us to our original question: what happens when a beam of subatomic particles traveling at nearly the speed of light meets the flesh of the human body? Perhaps because the realms of particle physics and biology are conceptually so far removed, its not only laypeople who lack the intuition to answer this question, but also some professional physicists.

In a 2010 YouTube interview with members of the physics and astronomy faculty at the University of Nottingham, several academic experts admitted that they had little idea what would happen if one were to stick a hand inside the proton beam at the LHC. Professor Michael Merrifield put it succinctly: Thats a good question. I dont know is the answer. Probably be very bad for you.

Professor Laurence Eaves was also cautious about drawing conclusions. [B]y the scales of energy we notice, it wouldnt be that noticeable, he said, likely with a bit of British understatement. Would I put my hand in the beam? Im not sure about that.

Such thought experiments can be useful tools for exploring situations that cant be studied in the laboratory. Occasionally, however, unfortunate accidents yield case studies: opportunities for researchers to study scenarios that cant be experimentally induced for ethical reasons. Case studies have a sample size of one and no control group.

But, as the neuroscientist V S Ramachandran has pointed out in Phantoms in the Brain (1998), it takes only one talking pig to prove that pigs can talk. On 13 September 1848, for example, an iron rod pierced through the head of the US railway worker Phineas Gage and profoundly changed his personality, offering early evidence of a biological basis for personality.

And on 13 July 1978, a Soviet scientist named Anatoli Bugorski stuck his head in a particle accelerator. On that fateful day, Bugorski was checking malfunctioning equipment on the U-70 synchrotron the largest particle accelerator in the Soviet Union when a safety mechanism failed and a beam of protons traveling at nearly the speed of light passed straight through his head, Phineas Gage-style.

Its possible that, at that point in history, no other human being had ever experienced a focused beam of radiation at such high energy. Although proton therapy a cancer treatment that uses proton beams to destroy tumors was pioneered before Bugorskis accident, the energy of these beams is generally not above 250 million electron volts (a unit of energy used for small particles). Bugorski might have experienced the full wrath of a beam with more than 300 times this much energy, 76 billion electron volts.

Proton radiation is a rare beast indeed. Protons from the solar wind and cosmic rays are stopped by Earths atmosphere, and proton radiation is so rare in radioactive decay that it was not observed until 1970. More familiar threats, such as ultraviolet photons and alpha particles, do not penetrate the body past skin unless a radioactive source is ingested.

Russian dissident Alexander Litvinenko, for instance, was killed by alpha particles that do not so much as penetrate paper when he unknowingly ingested radioactive polonium-210 delivered by an assassin. But when Apollo astronauts protected by spacesuits were exposed to cosmic rays containing protons and even more exotic forms of radiation, they reported flashes of visual light, a harbinger of what would welcome Bugorski on the fateful day of his accident.

According to an interview in Wired magazine in 1997, Bugorski immediately saw an intense flash of light but felt no pain. The young scientist was taken to a clinic in Moscow with half his face swollen, and doctors expected the worst.

Ionizing radiation particles such as protons wreak havoc on the body by breaking chemical bonds in DNA. This assault on a cells genetic programming can kill the cell, stop it from dividing or induce a cancerous mutation. Cells that divide quickly, such as stem cells in bone marrow, suffer the most. Because blood cells are produced in bone marrow, for instance, many cases of radiation poisoning result in infection and anemia from losses of white blood cells and red blood cells, respectively.

But unique to Bugorskis case, radiation was concentrated along a narrow beam through the head, rather than being broadly distributed from nuclear fallout, as was the case for many victims of the Chernobyl disaster or the bombing of Hiroshima.

For Bugorski, particularly vulnerable tissues, such as bone marrow and the gastrointestinal track, might have been largely spared. But where the beam shot through Bugorskis head, it deposited an obscene amount of radiation energy, hundreds of times greater than a lethal dose by some estimates.

And yet, Bugorski is still alive today. Half his face is paralyzed, giving one hemisphere of his head a strangely young appearance. He is reported to be deaf in one ear. He suffered at least six generalized tonic-clonic seizures. Commonly known as grand mal seizures, these are the seizures most frequently depicted in film and television, involving convulsions and loss of consciousness.

Bugorskis epilepsy is likely a result of brain tissue-scarring left by the proton beam. It has also left him with petit mal or absence seizures, far less dramatic staring spells during which consciousness is briefly interrupted. There are no reports that Bugorski has ever been diagnosed with cancer, though that is often a long-term consequence of radiation exposure.

Despite having nothing less than a particle accelerator beam pass through his brain, Bugorskis intellect remained intact, and he successfully completed his doctorate after the accident. Bugorski survived his accident. And as frightening and awesome as the inside of a particle accelerator might be, humanity has thus far survived the nuclear age.

It is a type of cancer that forms in a type of white blood cells known as a plasma cell. Your healthy plasma cells will fight infections and make antibodies that will attack germs, as per Mayoclinic. The cancerous plasma cells accumulate in the bone marrow. In this case, the cancer cells start producing an abnormal protein which further leads to complications. In simpler words, Multiple Myeloma happens when plasma cells become cancerous and grow out of control.

The symptoms can vary depending on an individual. Few reports suggest that initial symptoms may not be noticeable. But after a while, when it starts getting aggressive, as per Healthline, 4 major symptoms are noticeable which are referred to by the acronym CRAB which means:

Body gets a high level of calcium which can cause:

The cause is still unknown. It initiates with abnormal plasma cells which multiply in the bone marrow. Myeloma cells do not multiple and die, they divide indefinitely, as per Healthline.

Till now there is no cure for multiple myeloma. There are multiple treatments available including chemotherapy, interventional radiology, radiation therapy, stem cell transplantation, targeted therapy. Treatments are used when the disease starts getting worse.
