SOUTH SAN FRANCISCO, CA--(Marketwired - June 29, 2017) - VistaGen Therapeutics Inc.(NASDAQ: VTGN), a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders, today reported its financial results for its fiscal year ended March 31, 2017.

The Company also provided an update on its corporate progress, clinical status and anticipated milestones for AV-101, its orally available CNS prodrug candidate in Phase 2 development, initially as a new generation treatment for major depressive disorder (MDD).

"With a team of industry experts and a focused strategy in place, we have established a strong foundation and embarked on paths to achieve several key catalysts within the next 18 months. We anticipate our first catalyst within the next 9 months as the NIMH completes its AV-101 Phase 2 monotherapy study in MDD, a study being conducted and fully funded by the NIH. Additionally, we are working closely with the FDA and our Principal Investigator, Dr. Maurizio Fava of Harvard University Medical School, on our AV-101 Phase 2 adjunctive treatment study in MDD, which we anticipate will begin enrollment in the first quarter of 2018 and be completed by the end of 2018, with topline results available in the first quarter of 2019," commented Shawn Singh, Chief Executive Officer of VistaGen.

In addition to MDD, AV-101 may have therapeutic potential in several other CNS indications where modulation of NMDA receptors, activation of AMPA pathways and/or active metabolites of AV-101 play a key role, including for treatment of epilepsy, as a non-opioid alternative for management of neuropathic pain, and to address certain symptoms associated with Parkinson's disease and Huntington's disease.

Mr. Singh continued, "Our MDD clinical program is our top priority, and will remain so. Additionally, however, recent peer-reviewed publications suggest that AV-101 may have significant therapeutic potential as a non-opioid treatment alternative for pain management. We are also excited about AV-101's potential to reduce dyskinesia associated with standard levodopa, or L-DOPA, therapy for Parkinson's disease, based on results from previous non-clinical studies. Without diverting our priority focus on MDD, we plan to expand our AV-101 Phase 2 clinical program during the next year to include these important CNS indications with significant unmet need."

"We are also pleased to have advanced our cardiac stem cell program during fiscal 2017, through both our participation in the FDA's CiPA initiative focused on using novel human stem cell models to predict cardiac toxicity of new drug candidates long before animal and human studies, as well as our exclusive sublicense agreement with BlueRock Therapeutics, an emerging force in cardiac regenerative medicine, founded and funded by Bayer AG and Versant Ventures. Our initial revenue-generating milestone with BlueRock Therapeutics was completed during fiscal 2017. We are optimistic about this relationship's potential and the future of cardiac regenerative medicine. We believe these significant events over the past year have positioned us to create substantial value for our stakeholders in fiscal 2018 and beyond."

Intellectual Property Accomplishments

Capital Market Highlights

Financial Results for the Fiscal Year Ended March 31, 2017:

Revenue for the fiscal year ended March 31, 2017 totaled $1.25 million and was attributable to a sublicense agreement with BlueRock Therapeutics, for certain rights to the Company's proprietary technologies relating to the production of cardiac stem cells for the treatment of heart disease.

Research and development expense totaled $5.2 million for the fiscal year ended March 31, 2017, an increase of approximately 33% compared with the $3.9 million incurred for the fiscal year ended March 31, 2016. The increase in year-over-year research and development expense was attributable to increased focus on development of AV-101, including preparations to launch the Phase 2 Adjunctive Treatment Study in MDD.

General and administrative expense decreased to $6.3 million in the fiscal year ended March 31, 2017, from $13.9 million in the fiscal year ended March 31, 2016, primarily as a result of the decrease in non-cash stock compensation expense, partially offset by an increase in non-cash expense related to grants of equity securities in payment of certain professional services during fiscal 2017. Of the amounts reported, non-cash expenses, related primarily to grants or modifications of equity securities, totaled approximately $3.1 million in fiscal 2017 and $11.9 million in fiscal 2016.

Net loss for the fiscal years ended March 31, 2017 and 2016 was approximately $10.3 million and $47.2 million, respectively, the latter amount including a non-recurring, non-cash expense of approximately $26.7 million attributable to the extinguishment of approximately $15.9 million carrying value of prior indebtedness, including then-outstanding Senior Secured Convertible Notes, and conversion of such indebtedness into equity securities between May and September 2015 at a conversion price (stated value of the equity received) of $7.00 per share.

At March 31, 2017, the Company had a cash and cash equivalents balance of $2.9 million. Since late-March 2017, the Company sold units consisting of unregistered common stock and common stock warrants to accredited investors in a self-placed private placement, yielding approximately $1 million in cash proceeds to the Company.

Scientists have uncovered how nerve cells in the spinal cord are organised in precise patterns during embryo development - a finding that could give insight into regenerative medicine.

As embryos grow and develop they need the right cell types to end up in the right places inside forming organs. This is particularly important in the spinal cord where different nerve cell types must be accurately positioned so that circuits can assemble properly to control muscle movement. But until now the mechanism underlying nerve cell organisation in the spinal cord has remained poorly understood.

In a study published in Science, researchers at the Francis Crick Institute, the Institute of Science and Technology (Austria) and Ecole Polytechnique Fdrale de Lausanne (Switzerland) report that cells destined to become nerve cells in developing mouse embryos use two different signals spreading from opposite sides of the spinal cord - the back and belly side - to measure their position accurately. Based on this map, they turn into the appropriate nerve cell type. The research was funded by the European Research Council and Wellcome.

The team of biologists, physicists and engineers found that the amounts of the two signals originating from the back and belly sides of the body affect gene activity in developing nerve cells. Based on this gene activity in early development, the cells turn into the appropriate nerve cell type for that position in the spinal cord.

"We've made an important step in understanding how the diverse cell types in the spinal cord of a developing embryo are organised in a precise spatial pattern. The quantitative measurements and new experimental techniques we used, as well as the combined effort of biologists, physicists and engineers were key. This allowed us to gain new insight into the exquisite accuracy of embryonic development and revealed that cells have remarkable ability of to orchestrate precise tissue development," says Anna Kicheva, Group Leader at IST Austria.

"We have shed light on the long-standing question of how developing tissues produce the right cells in the right place in the right numbers," says James Briscoe, Group Leader at the Francis Crick Institute. "It's likely that similar strategies are used in other developing tissues and our findings might be relevant to these cases. In the long run this will help inform the use of stem cells in approaches such as tissue engineering and regenerative medicine. However, there is still much more to learn and we need to continue developing these interdisciplinary collaborations to further our biological understanding."

Scientists find mechanism behind precise spinal cord development - Medical Xpress

June 27, 2017 Just a few days old embryonic cell clusters: with functional Pramel7 (left), without the protein (right) the development of the stem cells remains stuck and the embyos die. Credit: Paolo Cinelli, USZ

Researchers from the University of Zurich and the University Hospital Zurich have discovered the protein that enables natural embryonic stem cells to form all body cells. In the case of embryonic stem cells maintained in cell cultures, this allrounder potential is limited. Scientists want to use this knowledge to treat large bone fractures with stem cells.

Stem cells are considered biological allrounders because they have the potential to develop into the various body cell types. For the majority of stem cells, however, this designation is too far-reaching. Adult stem cells, for example, can replace cells in their own tissue in case of injury, but a fat stem cell will never generate a nerve or liver cell. Scientists therefore distinguish between multipotent adult stem cells and the actual allrounders - the pluripotent embryonic stem cells.

Epigenetic marks determine potential for development

Differences exist even among the true allrounders, however. Embryonic stem cells that grow in laboratory cell cultures are in a different state than the pluripotent cells found inside the embryos in the first days of development. In a study in the journal Nature Cell Biology, researchers led by Paolo Cinelli of the University Hospital Zurich and Raffaella Santoro of the University of Zurich have now demonstrated the mechanism by which natural allrounders differ from embryonic stem cells in cultures.

At the center of their discovery is a protein called Pramel7 (for "preferentially expressed antigen in melanoma"-like 7) found in the cells of embryonic cell clusters that are just a few days old. This protein guarantees that the genetic material is freed from epigenetic marks consisting of chemical DNA tags in the form of methyl groups. "The more methyl groups are removed, the more open the Book of Life becomes," Cinelli says. Since any cell of the human body can develop from an embryonic stem cell, all genes have to be freely accessible at the beginning. The more a cell develops or differentiates, the stronger its genetic material is methylated and "sealed closed" again. In a bone cell, for example, only those genes are active that the cell requires for its function, the biochemist explains.

Protein is responsible for perfect pluripotency

Despite its short action period of just a few days, Pramel7 seems to play a vital role: When the researchers headed up by Cinelli and Santoro switched off the gene for this protein using genetic tricks, development remained stuck in the embryonic cell cluster stage. In the cultivated stem cells, on the other hand, Pramel7 is rarely found. This circumstance could also explain why the genetic material of these cells contains more methyl groups than that of natural embryonic cells - the perfect allrounders, as Cinelli calls them.

Using the stem cell function to regenerate bone tissue

His interest in stem cells lies in the hope of one day being able to help people with complex bone fractures. "Bones are great at regenerating and they are the only tissue that does not build scars," Paolo Cinelli says. The bone stumps must be touching, however, in order to grow together. When a bone breaks in multiple places and even through the skin, for example, in a motorcycle accident, the sections of bone in between are often no longer usable. For such cases, a bone replacement is required. His team is studying carrier materials that they want to populate with the body's own stem cells in the future. "For this reason, we have to know how stem cells work," Cinelli adds.

What makes stem cells into perfect allrounders - Phys.org - Phys.Org

By RENEE WEBB rwebb@catholicglobe.org

As the use of stem cell research and therapy continues to expand, one medical research institute located in Iowa strives to uphold Catholic teachings in bioethics.

The John Paul II Medical Research Institute (JP2MRI), a non-profit of Iowa City, was founded by Dr. Alan Moy in 2007 to address a shortcoming when it came to pro-life values being upheld concerning a variety of medical practices and issues. The doctor also is co-founder and CEO of Cellular Engineering Technologies (CET), a for-profit biotechnology company that manufactures commercial adult stem cells and other biotechnology products.

He explained that JP2MRI was founded a year after starting CET to advance the application of adult stem technology to clinical applications in the area of neurodegenerative disease, rare disease, cancer and chronic diseases of unmet needs or in underperformed diseased areas. His concern was that the United States was falling behind other countries in the area of adult stem cell research.

Recently, through collaborative research by JP2MRI and CET, a new method for creating safer induced pluripotent stem cells, or iPSC, for clinical use was discovered.

We started work in traditional adult stem cells over a decade ago, Moy explained. The controversy was that among the secular scientific community, adult stem cells were viewed as inferior to embryonic stem cells because they could not convert or differentiate into the variety of cells that embryonic stem cells could.

When iPSC technology was discovered by a Japanese Nobel laureate scientist about 10 years ago, it was an ethical alternative to embryonic stem cells. iPSC are noncontroversial adult stem cells that are genetically reprogrammed into embryonic-like stem cells without using human embryos.

But that technology had inherent safety issues just like embryonic stem cells. Most embryonic stem cells and iPS cells have the risk of causing tumors because of their genetic instability, Moy said. What we worked on was trying to reduce the tumor risk.

Building on the original iPSC technology, JP2MRI and CET developed a method by using a variety of chemicals to replace known cancer-causing genes in the process.

Now we have an iPS technology that is safer, said Moy, who noted an added benefit is potential reduced cost in drug development.

Potential applications

He spoke about practical applications of this technology such as expanding the use of stored cord blood stem cells for future medical treatment if a disease develops in the child.

We have a means where we can take the cord blood and make an iPS cell which can have lifelong utility and diversity, Moy added.

For those who do not have stored cord blood, he said all is not lost as blood can be drawn and stored for people to create their own iPS cell for future use.

This technology can also provide a viable alternative to embryonic stem cells and aborted fetal tissue that are currently used by the pharmaceutical industry, noted Moy, to produce vaccines, gene therapy, cell therapy and protein therapeutics.

Right now with protein manufacturing, half of it is done using animal cells to produce human proteins, he explained. The problem is some of the human proteins that are produced have some minor animal characteristics and they are not entirely human so there is a push to produce purely human proteins out of human cells. Unfortunately, the vast majority of human cell lines used in protein manufacturing or in vaccine development are derived from aborted fetal tissue.

Moy anticipates there will increasingly be a movement to shift toward human cell manufacturing, and if we dont come up with non-controversial human cells, we are going to have a lot of controversial human protein therapeutics, gene therapies and vaccines that will be distributed at hospitals that must be administered by doctors.

Morals and ethics

This can create moral and ethical problems. Catholic hospitals and/or Catholic doctors will be forced to decide if they will use that type of product made with illicit cells.

We have to have alternative products that are equal or better than the products that are currently out there, said Moy.

The Catholic Church, as well as the average person, may not always be aware of the unethical nature of many of these products. Moy said he has been trying to communicate areas of concern to the Catholic community for years.

The evolution of biotechnology over decades has become secularized and the power is in the secularists, he said. Advancement of illicit-cell treatment and therapy is a serious potential threat to the Catholic health care system including Catholic hospitals and Catholics who are healthcare providers.

Moy feels strongly about Catholics and the church being pro-active in the bioethics arena.

The only way in which we can influence the biotechnology field is through innovation, he said. Through innovation, if you produce something they want that has technical advantage, then one can influence the direction of biotechnology. Pro-life individuals need to move from a passive bystander to an activist role.

That is part of the reason he founded the JP2MRI, which is grounded in a pro-life bioethics that respects the dignity of every human life. While more than 300 non-profit institutes and organizations engage in and support human embryonic stem cell research, JP2MRI seeks to find cures and therapies exclusively using a variety of adult stem cells and specifically the iPSC, which are derived from adult cells.

Moy said they are not only looking for ways to produce a variety of products using the safer iPS cells, but plan to license them so other scientists, companies and industries can take advantage of these cells to pursue more ethical biotechnology.

Stem cells: JP2MRI, CET discover safer, more ethical biotechnology - Sioux City Catholic Globe

AVERY Beal has seen more suffering in her three short years than many people see in a lifetime.

The plucky toddler was diagnosed with Acute Lymphoblastic Leukaemia in August 2014 and has been fighting for her life ever since.

In the last three years, she has lived through chemotherapy, stem cell transplants, and bone marrow transplants.

It's been a rough few years on the rest of the family too.

Avery's mum Jen has spent the last two and a half years living in between the Beal family home on the Sunshine Coast and Lady Cilento's Children Hospital in Brisbane to care for Avery's medical needs.

Dad David has cared for the couple's other five children on the Coast, working to support them while home schooling their autistic twins.

To top it all off, Mr Beal said the family was recently given no choice but to move house after their lease ended.

Despite the tumultuous last few years, the ordeal might finally be over for Avery - although she's still very high risk, doctors have deemed her well enough to come home.

"Avery's been doing really good," Mr Beal said.

"She managed to get transplant stem cells from a baby's (umbilical) cord from another country.

"She managed to get to day 100 after the transplant, which at that stage doctors were happy for Jen and Avery to come home."

Avery had a second bone marrow transplant in March after her first one failed to stimulate Avery's blood cells to create healthy cells instead of cancerous ones.

"We're feeling good but the challenge is that she's still so high risk," Mr Beal said.

"With children, they'll generally speaking only do two bone marrow transplants.

"If it does come back there is literally nothing they can do. They would just make her comfortable.

"At the moment, we have tests done on her bone marrow every month so see that she's still cancer free."

Yesterday Avery had her central line - a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood transfusions -removed for the first time since her diagnosis in 2014.

The bubbly three-year-old will finally be able to go swimming - an experience that Avery has missed out on living on the Sunshine Coast.

Although the spritely tot has an 85% chance of relapsing, the family are confident that this is a good sign.

Despite all life has thrown at her, Avery is a happy child that lights up the lives of those around her.

"She's just incredible," Mr Beal said.

"It just amazes me over and over again how amazing she is on top of the treatments and the drugs; I think she's on eight different meds every morning and evening."

Mr Beal said the biggest hurdle the family currently face is the cost of Avery's multiple medications.

"She had a number on different things to get her body to a place for the transplant she's had in march," he said.

"Since then she's been on lots of different meds to make sure her body doesn't reject the transplant.

"For us finances are the biggest thing.

"Now that Avery is out of hospital we have to pay for medication and Jen's still having to do trips to Brisbane every week or fortnight"

Glimmer of hope in Avery's heartbreaking cancer battle - The Sunshine Coast Daily

The research studies carried out by John B. Gurdon (Anglo-Saxon) and Shinya Yamanaka (Japanese) were awarded the Nobel Prize in Medicine. These two scientists are considered of being the fathers of cellular reprogramming. They have achieved to create cells that behave identically to embryonic cells, however, without having to destroy human embryos. The Swiss Academy declared that both Gurdon and Yamanaka have revolutionized the current knowledge of how cells and organisms are developed, which has led to the perfection of the absurd methods of diagnosis and therapy.

Jhon Bertrand Gurdon, professor of the Zoology Department of the University of Cambridge, admitted of feeling extremely honored for such a spectacular privilege.

Moreover, Shinya Yamanaka discovered the so called induced pluripotent stem cells (iPS), which have the same proprieties of the embryonic ones and are able to turn into whatever other type of body cell. He asserted that he will continue to conduct research in order to contribute to society and medicine. For him that is a duty.

Yamanaka created four types of genes that supply cells with their pluripotentiality, in other words, the same capacity that embryonic stem cells have. If implanted in differentiated cells, for example of skin, they become pluripotent stem cells. The iPS supply a vast amount of plasticity just as embryonic stem cells do, however, without requiring the extermination or cloning of human embryos, since the initial cells can be obtained from the same patient. In this aspect, these cells have the same status as adult stem cells do, with the advantage of their versatility.

The dilema that has been stirred by the iPS is being resolved due to recent studies carried out by Leisuke Kaji (Universidad de Edimburgo) and Andreas Nagy (Samuel Lunenfeld Research Institute of Mount Sinai Hospital of Toronto).

The created iPS perennially retain their pluripotentiality. There is still the need of research to be conducted concerning the control of the difference between these cells in order for them to create the tissue that is necessary for each case. As Kaji affirms in The Guardian, it is a step towards the practical use of reprogrammed cells in the field of medicine, which could eventually lead to eliminating the need of counting on human embryos as the main source of stem cells.

Today the Charlotte Lozier Institute announced the release of its latest testimonial video at StemCellResearchFacts.org, a project of the Washington, D.C.-based research and policy group. The video revisits Jackie Stollfus, a lupus survivor whose story was first told in a video released in 2014.

Diagnosed at the age of 21 with systemic lupus, an autoimmune disease with no known cure, Stollfus endured years of debilitating symptoms that did not respond to medication before undergoing a transplant of her own bone marrow stem cells. Seven years later, she is healthy, active, and has been able to start a family. Adult stem cells saved my life, gave me a chance to have a life, gave me that chance to be a mom, she says.

Dr. David Prentice, Vice President and Research Director of the Charlotte Lozier Institute and an international expert on stem cells, hailed the new video, saying:

Follow LifeNews.com on Instagram for pro-life pictures.

Autoimmune diseases are notoriously challenging to treat, which makes Jackie Stollfuss recovery that much more striking. As this video shows, adult stem cells are the gold standard for stem cells when it comes to patient-centered science. Jackies story is only the latest example of innovation using adult stem cells. These non-controversial cells have led to validated healing in FDA-approved studies and peer-reviewed publications for patients with various diseases and conditions. Derived from bone marrow, umbilical cord blood, and other ethical sources, they have already been used to help over one million suffering patients around the globe.

Charlotte Lozier Institute President Chuck Donovan praised Congressional efforts to prioritize NIH funding for the most promising research:

The initial successes for these innovative therapies must be followed up with expanded resources to bring more treatments to the clinic and the bedside. The bipartisan, aptly-named Patients First Act (H.R. 2918) introduced by Rep. Jim Banks and Rep. Dan Lipinski is a good example of how policymakers can advance cutting-edge medicine. It directs resources for stem cells where they will do the most good for patients.

StemCellResearchFacts.org, a project of the Charlotte Lozier Institute, was established in 2009 to facilitate and form a worldwide community dedicated to helping individuals, patients and families discover, learn and share the latest advances in adult stem cell research. To that end, the website has published 16 video testimonials backed by peer-reviewed published science. These testimonials feature patients who have undergone successful therapies for a variety of conditions including autoimmune diseases, cancer, spinal cord injury, heart disease, and more using adult stem cells. They also convey the testimony of doctors and researchers on the merits of these treatments.

Jonathan Pitre is a teenager who loves to write science fiction as an escape from the painful disease that causes his body to be coated with wounds.

But the breakthrough bone-marrow transplant he just received at the University of Minnesota is anything but fantasy.

A decade after performing the worlds first bone marrow transplants to treat epidermolysis bullosa a rare and potentially fatal skin disease university researchers believe they have discovered a powerhouse new formula that advances their research, helps the body grow new skin and will allow patients such as Pitre, 17, to live longer, less painful lives.

Its really not miraculous. It certainly isnt science fiction, said Dr. Jakub Tolar, director of the Us stem cell institute and the world leader in transplant therapies for EB. Its based on the hard work of our predecessors. You accomplish something and then you use that knowledge to enhance the next step and the next step.

When they conducted the first transplants using donor bone marrow and umbilical cord blood in 2007, Tolar and colleagues were trying to produce a collagen that binds skin together and is lacking in EB patients. But they had little certainty about the types of cells that would work best.

Since then, research discoveries have allowed them to home in on mesenchymal stem cells, which they believe are uniquely good at bullying their way into the body and producing the missing collagen.

This is the first time ever, that I know of, when you are infusing them with the goal that these cells will stay, Tolar said. They will graft into the skin, set up shop there. Its as if these mesenchymal stem cells are coming home.

The doctors have also focused on transplants involving bone marrow from relatives, which is more familiar to the body and less likely to be rejected by the recipients.

A transplant like Jonathans occurs in a one-two punch. After receiving radiation and chemotherapy treatments to suppress the immune system, the patient receives an infusion of hematopoietic blood stem cells from a donor. Their job in this procedure is to give the patient a new immune system that wont reject the donors mesenchymal cells when they are transplanted later.

Since the U received federal approval last fall to offer the treatment experimentally, seven patients have undergone the procedure.

Tolar said all seven are progressing though Jonathan needed a second transplant this spring because the first one failed to knock out his old immune system.

Jonathan suffered an infection after his most recent transplant, which forced him to return to the hospital this month with high fevers and blisters on his face and mouth. Even so, Jonathans mother, Tina Boileau, said she has been taking pictures since the latest transplant to document the progress for her son, whose back is covered with wounds but for a healthy spot on his right shoulder blade.

Theyre actually in scabs, a sign of healing, said Boileau, who was the bone marrow donor for her sons transplant. Which Ive never seen before.

10 patients died

EB afflicts about one in every 30,000 to 50,000 people, though some forms are more severe than others. While it is known largely for the grotesque skin wounds it causes, the disease is often fatal because it leads to severe infections or skin cancers. It can also create internal wounds to the patients digestive tract, which impairs eating.

The desperation of children with the disorder and their families compelled the first transplants at the university in 2007. Even using the old approach, about two-thirds of patients saw improvements, but 10 of the first 30 recipients died from their diseases or complications of treatment.

The Us latest success with mesenchymal stem cells might end up being an incremental step. Earlier this year, Tolar and his colleagues published research showing success in an even more advanced therapy: laboratory testing using gene editing that can reprogram the patients cells to produce healthy skin cells and tissue.

Further successes could lead to clinical trials in which a patients own dysfunctional cells would be reprogrammed, preventing the need for chemotherapy and the replacement of their immune systems.

Before they came to the U, Boileau said, her son had run out of options. Managing his pain, once possible with over-the-counter Advil, had come to require opioid painkillers such as methadone. That made him groggy and complicated his already awkward life at school back home in Ottawa. Jonathan wasnt even able to eat lunch in the school cafeteria for fear of being accidentally bumped and suffering fresh wounds.

Then the Canadian government approved funding to make him his countrys first recipient of an experimental bone marrow transplant for EB. And his home community rallied to support the family. Among other things, he has visited with pro hockey players from the Ottawa Senators, which also issued a contract adding him to their scout staff.

After seeing the pain her son has endured, Boileau said shell never complain about a blister from new shoes. She marvels at his optimism and his use of science fiction reading and writing to escape.

Inspired by the success of Christopher Paolini, who wrote the acclaimed Eragon science fiction novel as a teen, Jonathan has resolved to write his own science fiction book about a teen who develops the ability to overcome EB. The project resulted in long visits and e-mail exchanges between Tolar and his patient about medicine and physics, because Jonathan wants his story grounded in reality.

Theyre almost soul mates, Boileau said.

Tolar said he enjoys the intellectual relationship and that his patient is providing an example of hope and teaching others about the disease: He may be the only person [who] can bring this kind of view to others, Tolar said.

U team discovers 'powerhouse' new treatment in fight against deadly skin disease - Southernminn.com

In the future, when a couple wants to reproduce, they will not make a baby in a bed or in the backseat or a car, or under a Keep Off the Grass sign, says Henry Greely, the director of the Center for Law and the Biosciences at Stanford Law School.

Instead, they will go to a clinic. Using stem cells from the couples skin or other non-reproductive organs, scientists will be able to make eggs and sperm, which will be combined into embryos. Each of those embryos will have its own gene sequence, Greely says. The parents will be asked: What do you want to know about these embryos? And theyll be told.

Twenty or 30 years from now, parents will be able to screen their potential kids for genetic abnormalities, pre-disposal to disease, sex, and even cosmetic features like hair, eye, and skin color, Greely claims. The new way of baby-making will save women the pain of going through fertility treatments, he says, and it will prevent disease, save health-care costs, and give non-traditional families more chances to have children. If this reproductive future comes to pass, it will also come with a tangle of moral, legal, and medical questionsones that wont be easy to resolve, despite what Greely may think.

When Greely tells people about his theorywhich is the subject of his 2016 book, The End of Sex and the Future of Human Reproductionthey tend to say, This is Gattica, or this is Brave New World, he said during an interview with the New York Times reporter Carl Zimmer on Monday at the Aspen Ideas Festival, which is co-hosted by the Aspen Institute and The Atlantic. Greely is skeptical of this argument. This is not designer babies. This is not super babies. This is selecting embryos, he said.

Greely gets some of his confidence from the limits of science. Geneticists likely wont be able to predict kids behavioral traits, he said, like their aptitude for math or agility on a sports field. But they may be able to anticipate some traits, like intelligence, in broad strokes. Being able to tell parents that this embryo has a 60 percent chance of being in the top half [of their school class], this embryo has a 13 percent chance of being in the top 10 percentI think thats really possible, he said.

Scientists have been screening embryos using a process called preimplantation genetic diagnosis, or PGD, for two and half decades, Greely said. This allows for the detection of some genetic diseases, as well as determining the sex of the embryo. Up until now, it has been expensive and arduous, but with new technologyincluding the expanded use of stem cellsit will become easy, he said. The people most likely to lead the way on easy PGD are those with fertility trouble, he argues, or those who cant have their own biological kids, including same-sex couples. For these people, the process seems to be a clear potential win: Once hopeless, they may soon be able to have biological children of their own.

But if the process does indeed advance in the way Greely predicts, it will come with big ethical challenges. Safety is a big issue, he said. Coercion is a big issue: Will you be forced to do this? No matter how easy PGD becomes, it will always be expensive, meaning that babies from rich families would gain even more advantages over other people before they leave the womb. The procedure also challenges the disability-rights movement, Greely pointed out: It implicitly suggests that some traits, and thus some people, are preferable to others.

Theres very little about our modern lives that a God from 3000 years ago would have expected.

Some critics may also claim this process is against Gods will, Greely added. I dont have a lot of confidence in the intellectual strength of that argument, but I think it has a lot of visceral support.

Despite Greelys skepticism, this seems to be the greatest potential objection to a world of skin-cell babies and intensive genetic screening: It assumes that the creation of life is a matter of pipettes and petri dishes, not something greater. While the widespread use of contraceptives has largely divorced sex from procreation, this process would represent the final severing. As Greely pointed out, the very meaning of sex would change. Most people have sex and it doesnt result in a baby, he said. They do it because they like it. They do it as a token of love. They do it because theyre forced to. They do it to make money. Pleasure, ultimately, will be a main driver of sex, he added.

For the many peoplereligious or notwho believe that life is not ultimately a matter of science, the world of easy PGD may seem disorienting, even morally disturbing. But Greely didnt think religious or moral arguments could persuade someone like him, or society more broadly, that easy PGD isnt a good idea.

If you, coming from a Catholic background, try to convince me, coming from a non-Catholic background ... that wouldnt work for me, he said. I need a more intellectual argument than one based on my faith or the tablets brought down from the mountain for me say this. Theres very little about our modern lives thats natural or what a God from 3000 years ago would have expected or wanted, including all of modern medicine.

As head-spinning as these theoretical ethical challenges are, perhaps easy PGD wont be as common as Greely thinks. After all, he joked, were never going to get rid of teenagers in the back seat of a car.

Making Babies, No Sex Necessary - The Atlantic

A new study at Tel Aviv University shows that stem cell therapy, one of the few treatments available to patients with severe and end-stage heart failure, can actually harm them unless it is done differently.

We concluded that stem cells used in cardiac therapy should be drawn from healthy donors or be better genetically engineered for the patient, said lead researcher Jonathan Leor of the universitys Sackler Faculty of Medicine and Sheba Medical Center.

Doctors use tissue or adult stem cells to replace damaged tissue, which encourages regeneration of blood vessel cells and new heart muscle tissue. But cardiac stem cells from a diseased heart can lead to a toxic interaction via a molecular pathway between the heart and the immune system, the study found.

We found that, contrary to popular belief, tissue stem cells derived from sick hearts do not contribute to heart healing after injury, Leor said. Furthermore, we found that these cells are affected by the inflammatory environment and develop inflammatory properties. The affected stem cells may even exacerbate damage to the already diseased heart muscle.

Each year, more than 700,000 people suffer myocardial infarction, aka a heart attack. Thanks to medical advances, there are myriad ways for a doctor to get the blood properly pumping and save a persons life. A cardiologist might give a patient medication to clear or loosen blockages. Or a doctor might insert a catheter to remove the clot, or place stents in the artery so it stays open.

These interventions have vastly improved survival rates, but they dont heal the damage caused by a cardiac event. The heart is really just one big muscle, and trauma to any muscle does some damage, which becomes scar tissue. Scar tissue on the heart means it functions far less optimally, which eventually leads to heart failure.

Short of a transplant, there isnt a long-term option to fix a damaged ticker. But a team of researchers say theyve come up with a high-tech solution that could revolutionize cardiology. Using 3-D printing technology, Brenda Ogle, an associate professor of biomedical engineering at the University of Minnesota-Twin Cities, has created a patch a doctor could apply to mend a patients broken heart.

The concept is to imprint proteins that are native to the body, says Ogle. Weve used stem cellderived cardiac musclecardiac myocytesand actually mixed those with other cell types needed for blood vessels. This, she says, prevents what would otherwise happen naturally: The formation of a different type cells known as fibroblasts, which secrete scar tissue.

Ogle and her team of 3-D printing experts, clinical cardiologists and stem cell engineers have successfully tried the patch on mice. First, the team induced cardiac arrest in the rodents. When they then placed the cell patch on a mouse, researchers saw a significant increase in the functional capacity of the organ after just four weeks. We generated the continuous electric signal across the patch, and we can pace it: We can increase the frequency of beating up to three hertz, which is similar to a mouse heart, says Ogle who, this past January, published the findings of their experiment in Circulation Research, a journal from the American Heart Association.

The results of the experiment were so inspiring that in June 2016 the National Institutes of Health awarded her team a grant of more than $3 million, so they can now give pigs heart attacks and fix them with the patch. However, it will take some time to see their innovation in surgical departments, since using biological products such as cells requires a long regulatory process and, of course, quality assurance.

The replacement of muscle has been the holy grail for some time, says Ogle. Now we finally have the ability to take stem cells out of the body and develop the protocols to do that.

How 3D Printing Can Help Mend a Broken Heart - Newsweek

June 15, 2017

Patients with severe and end-stage heart failure have few treatment options available to them apart from transplants and "miraculous" stem cell therapy. But a new Tel Aviv University study finds that stem cell therapy may, in fact, harm heart disease patients.

The research, led by Prof. Jonathan Leor of TAU's Sackler Faculty of Medicine and Sheba Medical Center and conducted by TAU's Dr. Nili Naftali-Shani, explores the current practice of using cells from the host patient to repair tissueand contends that this can prove deleterious or toxic for patients. The study was recently published in the journal Circulation.

"We found that, contrary to popular belief, tissue stem cells derived from sick hearts do not contribute to heart healing after injury," said Prof. Leor. "Furthermore, we found that these cells are affected by the inflammatory environment and develop inflammatory properties. The affected stem cells may even exacerbate damage to the already diseased heart muscle."

Tissue or adult stem cells"blank" cells that can act as a repair kit for the body by replacing damaged tissueencourage the regeneration of blood vessel cells and new heart muscle tissue. Faced with a worse survival rate than many cancers, many heart failure patients have turned to stem cell therapy as a last resort.

"But our findings suggest that stem cells, like any drug, can have adverse effects," said Prof. Leor. "We concluded that stem cells used in cardiac therapy should be drawn from healthy donors or be better genetically engineered for the patient."

Hope for improved cardiac stem cell therapy

In addition, the researchers also discovered the molecular pathway involved in the negative interaction between stem cells and the immune system as they isolated stem cells in mouse models of heart disease. After exploring the molecular pathway in mice, the researchers focused on cardiac stem cells in patients with heart disease.

The results could help improve the use of autologous stem cellsthose drawn from the patients themselvesin cardiac therapy, Prof. Leor said.

"We showed that the deletion of the gene responsible for this pathway can restore the original therapeutic function of the cells," said Prof. Leor. "Our findings determine the potential negative effects of inflammation on stem cell function as they're currently used. The use of autologous stem cells from patients with heart disease should be modified. Only stem cells from healthy donors or genetically engineered cells should be used in treating cardiac conditions."

The researchers are currently testing a gene editing technique (CRISPER) to inhibit the gene responsible for the negative inflammatory properties of the cardiac stem cells of heart disease patients. "We hope our engineered stem cells will be resistant to the negative effects of the immune system," said Prof. Leor.

Cardiac stem cells from heart disease patients may be harmful - Medical Xpress

AUSTIN, Texas -- Gov. Greg Abbott has signed a new law that allows terminally ill or those which chronic diseases receive stem cell treatments in Texas.

Stem cell therapy is the use of stem cells to treat or prevent a disease or condition, and is often patient's last hope for improvement.

Bone marrow transplant is the most widely used stem-cell therapy, and can often help those with multiple sclerosis and other diseases.

House Bill 810, which was introduced by Rep. Tan Parker, R-Flower Mound, passed in both the Texas House and Senate.

"It is easy to fall into the trap of viewing legislation as just words on a piece of paper," said Sen. Paul Bettencourt, R-Houston, the bill's sponsor in the Senate. "But for the many people who are ill with multiple sclerosis and other diseases that stem cell therapy has the hope of solving in our lifetime, I look at this bill, I look at the possibility of what can happen in the 21st Century, with Texas taking the lead on adult stem cell treatments and this bill has the potential to extend lives and make a difference for these patients."

The Texas Medical Board will be responsible for writing the rules for the treatment.

"Everyone has a zest for life. This adult stem cell treatment possibility gets government out of the way to let these new therapies flourish and give these patients hope for a future good quality of life," Bettencourt added.

The legislation takes effect Sept. 1.

-- Value of Stem Cell Therapy --

According to the National Institues of Health, stem cellshave the remarkable potential to develop into many different cell types in the body during early life and growth.

In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive.

When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Doctors say stem cells are important for living organisms for many reasons.

In the 3- to 5-day-old embryo, called ablastocyst, the inner cells give rise to the entire body of the organism, including all of the many specialized cell types and organs such as the heart, lungs, skin, sperm, eggs and other tissues.

In some adult tissues, such as bone marrow, muscle, and brain, discrete populations of adult stem cells generate replacements for cells that are lost through normal wear and tear, injury, or disease.

Legacy of Houston's first 'Bubble Boy' helping children born decades later

Though he only lived for 12 years, the life of Houston's David Vetter captivated the public as he grew up isolated from germs and human touch due to a rare, inherited condition calledSevere Combined Immunodeficiency Disorder, or SCID.

This weekend HoustonChronicle.com told the story of a Houston child named Sebastian Romero who suffers from the same condition.

Vetter lacked the white blood cells that fight infection, meaning any germ was a potential killer. When he was born in 1971, there was no treatment. The "Star Wars"-loving kid died in February 1984after doctors attempted an experimental bone marrow transplant.

PREVIOUS:The 'boy in the bubble' who captivated the world

Story continues below...

A TV movie starring John Travolta partially based on Vetter's story was released in 1976, but it took many liberties with his situation. Hollywood has also attempted to turn bubble boy cases into comedy with 2001's "Bubble Boy" starring Jake Gyllenhaal and a 1992 episode of Seinfeld.

Born in February, the cute, chubby-faced Romero has decades of medical research on his side that Vetter did not. But Romero isn't completely out of the woods, as reporter Mike Hixenbaugh writes on HoustonChronicle.com. His family has a hard road ahead of them. SCID is still a very scary condition in any decade, but the doctors at Texas Children's Hospital are calling on lessons from 33 years ago to help save the boy's life.

PREVIOUS:'Bubble boy' medical legacy lives on years after death

Over the past few years, Texas Children's has treated several SCID babies, and most had been cured through bone marrow or stem cell transplants.

After a nationwide search, no matching donor could be found for Sebastian. Texas Children's instead proposed giving a stem cell transplant from a half-matching family member, the same treatment that failed to cure David more than 30 years ago.

If Sebastian is going to survive, it will be his mother's stem cells and lessons from the Bubble Boy that will save him.

The Romero family is currently holding an online fundraiser to help them pay for some of the expenses related to Sebastian's ongoing care.

Oper Technology, a Hong Kong biotechnology start-up, has pioneered what it claims is a world first in stem cell treatment that it says could potentially help millions of patients suffering from Alzheimers and Parkinsons diseases.

The business was co-founded by Hong Kong Baptist Universitys Professor Ken Yung, who specialises in neurobiology and neurological diseases in the universitys biology department.

He and his team has now developed a method of harvesting neural stem cells from the brains of live subjects using specially developed nanoparticles.

The exploration of using stem cells to repair damaged neural cells is not a new concept. Scientists in the US and elsewhere have experimented using stem cells from fat and skin, developing them into neural cells.

But Yung claims his team is the first to successfully harvest stem cells directly from the brain and re-inject the developed neural cells back into a live subject, thereby artificially regenerating any cells which have died off, due to neurological diseases from neural stem cells themselves.

Stem cells have the potential to develop into different types of cells with specialised functions.

The nanoparticles which are made of a type of iron oxide work like magnets to attract the stem cells within the brain.

Yung said these can then be developed into more specific neural cells and re-injected into the brain to replace damaged cells caused by diseases such as Alzheimers and Parkinsons, where neurons in the patients brains progressively die off with time.

He suggests the treatment could benefit almost 100 million patients around the world, who suffer from neurodegenerative diseases, including strokes.

China alone has the largest population of people with dementia, with an estimated 23.3 million now projected to suffer from the condition by 2030, according to the World Health Organisation.

Yung co-founded Oper Technology and serves as its chairman.

The company is being developed under Hong Kong Science and Technology Parks Incu-Bio programme, which provides select biotechnology start-ups with laboratory and support services, and ultimately it aims to commercialise its medical technology.

If you put the [developed] cells in a different environment from where the [stem cells are harvested], there might be [misdirected] growth in an uncontrolled environment, said Yung.

We want to use neural cells to repair neural cells, and since the stem cells and re-injected neural cells are from the same micro-environment, there will not be uncontrollable growth.

The method has proven to be very successful when tested on rats, especially in cases of Parkinsons, according to Yung, who suggested the method could eventually become an ultimate treatment for the disease.

Furthermore, the risks of this treatment are similar to what is currently on the market today, he added.

The treatment could also help to treat early-stage Alzheimers patients, slowing down or even halting the degeneration process, although Yung acknowledged that its effectiveness in treating terminal stage patients may be limited since it would be difficult to regenerate enough neural cells when patients brains have shrunk due to the condition.

While animals subjected to the treatment displayed an improvement in neural function following the re-injection, the team has yet to start on clinical trials as such cell therapy is still nascent and largely unregulated in Hong Kong.

Oper Technology is currently seeking investment and often sets up booths at conferences such as last weeks EmTech Hong Kong conference, which focuses on innovation and emerging technologies.

Yung hopes to raise enough funds to begin clinical trials in Australia in the near future, where autologous cell therapies are legal and thus provides an ideal environment for clinical trials.

Panchwati Tower on Harmu Road in Ranchi where the stem cell bank is expected to come up. (Hardeep Singh)

In what may be a game-changer for healthcare in Jharkhand, a group of doctors from Ranchi have teamed up with a Mumbai-based pioneering research firm to plan the first stem cell bank of eastern India in the state capital.

Stem cells are undifferentiated biological cells that can differentiate into specialised cells and divide to produce more stem cells. They can be transplanted routinely to treat a variety of blood and bone marrow diseases, including cancer and immune disorders, while extensive research is underway on their potential to cure neurological and muscular problems.

In short, a stem cell bank in Ranchi will allow residents to store their embryonic or adult stem cells, which can be accessed anytime to treat ailing blood relatives.

Dr Deepak Verma, a senior orthopaedic consultant in the city specialising in difficult trauma surgery, said if everything went according to plan, the stem cell bank was expected to debut at Panchwati Tower on Harmu Road in another three to six months.

Dr Verma, along with pathologist Dr Sangita Agrawal and orthopaedic surgeon Dr S.N. Yadav, will form the core team of the Rs 6.5-crore facility, which will be set up in association with stem cell banking company ReeLabs, Mumbai.

"Ranchi will boast the fifth stem cell bank in India after Mumbai, Delhi, Chennai and Ahmedabad. It will be first such facility in eastern India. We plan to establish a stem cell treatment centre and a cancer immunotherapy centre to turn Ranchi into a healthcare destination," Dr Verma told this newspaper on Sunday.

While the bank will sprawl over an area of 5,000sqft, another 6,000sqft will be reserved for the therapy centres.

Elaborating on the banking system, the doctor said stem cells would be stored in cryogenic vials at minus 176 degrees and liquid nitrogen would be used to acquire the very low temperatures.

"People wishing to use the stem bank service will have to open an account. The bank will then collect stem cells from different sources such as placenta, amniotic sac, amniotic fluid, umbilical cord blood and cord tissue, menstrual blood, dental pulp, bone marrow and peripheral blood," Dr Verma said.

To deposit the stem cells, one may have to pay Rs 45,000 to Rs 2 lakh, depending on the package chosen.

"Those who will deposit stem cells can access the same for blood relatives suffering from 110 listed diseases that cannot be treated using conservative medicines," the doctor said, adding that stem cell therapy could help in cases of leukemia, thalassemia, Alzheimer's disease, cardiovascular diseases, stroke, diabetes and cirrhosis of liver, among others.

Do you think people in the state are aware of stem cell therapy?

Researchers at the Institute of Bioengineering and Nanotechnology (IBN) of A*STAR have engineered a three-dimensional heart tissue from human stem cells to test the safety and efficacy of new drugs on the heart.

Cardiotoxicity, which can lead to heart failure and even death, is a major cause of drug withdrawal from the market. Antibiotics, anticancer and antidiabetic medications can have unanticipated side effects for the heart. So it is important to test as early as possible whether a newly developed drug is safe for human use. However, cardiotoxicity is difficult to predict in the early stages of drug development, said Professor Jackie Y. Ying, Executive Director at IBN.

A big part of the problem is the use of animals or animal-derived cells in preclinical cardiotoxicity studies due to the limited availability of human heart muscle cells. Substantial genetic and cardiac differences exist between animals and humans. There have been a large number of cases whereby the tests failed to detect cardiovascular toxicity when moving from animal studies to human clinical trials*.

Existing screening methods based on 2D cardiac structure cannot accurately predict drug toxicity, while the currently available 3D structures for screening are difficult to fabricate in the quantities needed for commercial application.

To solve this problem, the IBN research team fabricated their 3D heart tissue from cellular self-assembly of heart muscle cells grown from human induced pluripotent stem cells. They also developed a fluorescence labelling technology to monitor changes in beating rate using a real-time video recording system. The new heart tissue exhibited more cardiac-specific genes, stronger contraction and higher beating rate compared to cells in a 2D structure.

Using the 3D heart tissue, we were able to correctly predict cardiotoxic effects based on changes in the beating rate, even when these were not detected by conventional tests. The method is simple and suitable for large-scale assessment of drug side effects. It could also be used to design personalized therapy using a patients own cells, said lead researcher Dr Andrew Wan, who is Team Leader and Principal Research Scientist at IBN.

The researchers have filed a patent on their human heart tissue model, and hope to work with clinicians and pharmaceutical companies to bring this technology to market.

Home General Health Origin of age-related muscle loss discovered

When were young, we feel like we can accomplish anything. We can go anywhere and do anything because we dont feel encumbered by our physical limitations. However, when we age, we start to lose this feeling of empowerment. Our once-impressive physical physique fades away, leaving us weak and defenseless.

However, new research into the reasons why we lose muscle cells as we age may lead to the development of new drugs that can slow the process of muscle decline.

It was previously thought that the driving factor behind age-related muscle decline was the loss of motor neuronsnerve cells in the spinal cord controlling muscle. Starting in our 30s, we begin to notice that activities that once came easily are now difficult.

When we reach our 70s and 80s, we become weak and frail, having to depend on others to lend us their strength on a daily basis. No amount of diet and exercise can prevent this inevitable result.

The pursuit of preserving our youth has been a goal for many researchers and scientists. Understand how and why the body ages over time is something worth pursuing in the hopes of improving lives.

Research using mouse models has found that muscle stem cells play a very important role in lifelong maintenance of muscle. This challenges the current, widely accepted theory of motor neurons.

Muscle stem cell pools were seen to reside in muscle tissue that responds to exercise and injury. These stem cells are directly involved in repair and growth of muscles. It is the dying off of these stem cells that is theorized to be the driving factor for muscle loss.

Mice that were genetically altered to prevent muscle stem cell loss maintained healthier muscles in old age.

Subsequently, no evidence was found linking motor neurons to age-related muscle loss.

I think weve shown a formal demonstration that even for aging sedentary individuals, your stem cells are doing something. They do play a role in the normal maintenance of your muscle throughout life, said study author Joe Chakkalakal, Ph.D., assistant professor of Orthopaedics in the Center for Musculoskeletal Research at the University of Rochester Medical Center.

This week alone in the news weve seen air strikes, suicide bombings and murders caused by hate. Violence over the hue of someones skin, the way they speak or how they dress. Hate-filled speech by neighbors at meetings and on Facebook. At dinner yesterday, my 8-year-old step-daughter asked her dad, Whats a bomb? My heart is heavy.

Its easy to forget that we are more alike than we are unalike. I offer to you a different perspective.

Six years ago my brother got the call he had Hodgkin Lymphoma, a cancer that starts in cells that are part of the bodys immune system. He was 28 years old. It started as a visible lump under his collar bone, and sometimes you wonder how can so much suffering be caused by such a little lump? And so my story begins.

About one year into his treatment, he reached remission, and from there he was required to undergo an autologous stem cell transplant (a transplant using his own stem cells) to replace his bone marrow and stem cells that were destroyed by chemotherapy and radiation. Fast-forward 10 or so months and my brothers cancer returned. This time the treatment plan had to change his body needed help actually fighting the cancer cells, rather than just a replenishment of normal blood cells. This time around, he required an allogeneic stem cell transplant (a transplant using the stem cells from a healthy donor) and as his sister, I needed to be tested to see if I was a tissue match.

This was all new to me and our family. You hear a lot about cancer. We all know someone who has it, if you dont have cancer yourself. But I knew nothing about stem cell transplants or what it meant to be a donor. First we had to find out if my brother and I were a match.

I received a kit in the mail and all I had to do was swab the inside of my cheek, place the swab inside a sealed bag, and mail it back to the hospital. A week or so later, my brother got the news from his doctor that changed our lives. I was, in fact, a match a near perfect match and we could move forward with his second stem cell transplant.

At this point in my story, youre probably thinking, Of course, youd be a match, youre his sister. I assumed so, as well. Read on.

On Aug. 12, 2016, my brother and I underwent our stem cell transplant at Dana Farber/Brigham and Womens Hospital in Boston. There are two different ways to donate stem cells peripheral blood stem cells (stem cells extracted from your blood after receiving five days of injections of a drug called filgrastim, used to increase the number of blood-forming cells in your bloodstream) and bone marrow (a surgical procedure where doctors use needles to withdraw liquid marrow from both sides of the back of your pelvic bone). Due to my brothers specific treatment plan, he required pure bone marrow, and my bone marrow was taken from my pelvis. Two liters worth of my bone marrow was processed at Dana Farber and then brought to my brother immediately, who received it via an IV drip.

So how does my story end? Why am I telling you all this?

My brother is thriving. My pelvis has healed. And we were absolutely blessed to find a match right within our family.

The reality is that fewer than 30 percent of patients with a blood cancer or blood disease will find a related-donor; the other 70 percent, thousands of patients with blood cancers like leukemia and lymphoma, sickle cell anemia or other life-threatening diseases, depend on the national bone marrow registry to find a match to save their life. Some day you or someone you love might depend on a complete stranger who might be a Muslim, a Republican, gay or straight. But it wont matter because from the inside, they will be the same.

I plead with you to remember that we are more alike than we are unalike, and to do something positive for humanity.

You can visit http://www.bethematch.org and join the Be The Match national bone marrow registry.

Or you can attend one of my in-person donor drives in Greenfield over the next few months. The first will be this Saturday, June 10, from 2 to 4 p.m. at the Pints in the Park event at the Greenfield Energy Park.

If you are between the ages of 18 and 44, patients especially need you. You could be someones cure.

I note the obvious differences

between each sort and type,

but we are more alike, my friends,

than we are unalike.

We are more alike, my friends,

than we are unalike.
