Like private investigators on a stake out, St. Jude Childrens Research Hospital scientists used patience and video surveillance-like tools to identify cells that trigger blood cell development. The findings offer clues for making blood-forming stem cells in the laboratory that may ultimately help improve access to bone marrow transplantation.

The research will likely open new avenues of investigation in stem cell biology and blood development and provide insight to aid efforts to make transplantable hematopoietic stem cells in the lab, said corresponding author Wilson Clements, Ph.D., an assistant member of the St. Jude Department of Hematology.

Blood-forming stem cells are capable of making any type of blood cell in the body. They are also used in transplant therapies for cancers like leukemia or other blood diseases like sickle cell. They are starting to be used to deliver gene therapy. However, a shortage of suitable donors limits access to treatment, and efforts to produce blood from pluripotent stem cells in the laboratory have been unsuccessful. Pluripotent stem cells are the master cells capable of making any cell in the body.

All blood-forming stem cells normally arise before birth from certain endothelial cells found in the interior blood vessel lining of the developing aorta. This processincluding how endothelial cells are set on the path to becoming blood stem cellsis not completely understood.

Clements and first author Erich Damm, Ph.D., a St. Jude postdoctoral fellow, have identified trunk neural crest cells as key orchestrators of the conversion of endothelial cells to blood stem cells. Trunk neural crest cells are made in the developing spinal cord and migrate throughout the embryo. They eventually give rise to a variety of adult cells, including neurons and glial cells in the sympathetic and parasympathetic nervous system, which control feeding, fighting, fleeing and procreating.

Using time-lapse video, the researchers tracked the migration of neural crest cells in the transparent embryos of zebrafish. Zebrafish and humans share nearly identical blood systems, as well as the programming that makes them during development. After about 20 hours, the neural crest cells had reached the developing aorta. After hour 24, the migrating cells had cozied up to the endothelial cells in the aorta, which then turned on genes, such as runx1, indicating their conversion to blood stem cells.

The investigators used a variety of methods to show that disrupting the normal migration of neural crest cells or otherwise blocking their contact with the aorta endothelial cells prevented the birth of blood stem cells. Meanwhile, other aspects of zebrafish development were unaffected.

Researchers have speculated that the endothelial cells that give rise to blood-forming stem cells are surrounded by a support niche of other cells whose identity and origins were unknown, Damm said. Our results support the existence of a niche, and identify trunk neural crest cells as an occupant.

Adult bone marrow includes niches that support normal function and notably feature cells derived from trunk neural crest cells.

The findings also suggest that trunk neural crest cells use a signal or signals to launch blood stem cell production during development. The researchers have eliminated adrenaline and noradrenaline as the signaling molecules, but work continues to identify the signaling proteins or small molecules involved.

The research was supported in part by a grant (R00HL097) from the National Heart, Lung and Blood Institute of the National Institutes of Health; the March of Dimes; and ALSAC, the fundraising arm of St. Jude.

First bone marrow stem cell transplantations performed in Armenia

YEREVAN, APRIL 10, ARMENPRESS. The first two stem cell transplantations of bone marrow in Armenia were performed in the Yolyan Hematology Center by Professor Dr. NicolausKrger, head of the transplantation department of Hamburgs Eppendorf Clinic and the Yolyan Hematology Clinics team.

Professor Smbat Daghbashyan, head of the Armenian transplantation doctors team, told reporters the transplantation passed successfully.

The patients, who trusted her health to the doctors, is a woman from Artsakh, who had to travel abroad for undergoing the same surgery. The second patient is a man, who had a repetition of the disease after chemotherapy, he said, adding that 60 patients annually need stem cell transplantation in Armenia.

We will continue cooperation with our colleagues from Hamburg. The patient who had to receive the transplantation in Hamburg, can get it here the same way. We will perform transplantations in 7-10 patients during this year, since this a gradual process, he said.

Dr. NicolausKrger congratulated the Armenian doctors in introducing the new treatment method in Armenia.

This method is considered to be innovative in the world and is used for treating cancerous diseases, he said.

The monitor shows mesenchymal stem cells (the white) aligned along graphene circuits (the black). CREDIT: Photo by Christopher Gannon.

Scientists searching for the means to regenerate nerves might find it difficult to acquire the important tools needed for research. One such example is Schwann cells that form sheaths enclosing axons, which are tail-like portions of nerve cells that convey electrical impulses. In addition to promoting regeneration of the axons, the Schwann cells discharge substances, boosting the health of nerve cells.

To put it differently, the Schwann cells prove to be helpful to researchers working towards the regeneration of nerve cells, particularly peripheral nerve cells located outside the spinal cord and brain. However, the count of Schwann cells is too low to be of any use.

Scientists have been using noncontroversial, readily available mesenchymal stem cells that is, bone marrow stromal stem cells with the ability to form cartilage, bone, and fat cells by differentiating them into Schwann cells by means of a chemical process. Unfortunately, this process is costly and laborious.

The Iowa State University research team have been looking for a better way to transform the stem cells into Schwann-like cells, and have created a nanotechnology that employs inkjet printers for printing multi-layer graphene circuits. It also employs lasers to treat and enhance conductivity and the surface structure of the circuits.

The mesenchymal stem cells have been found to adhere and grow in a better manner on the rough, raised, and 3-D nanostructures of the treated circuit. When small doses of electricity of about 100 mV were applied for 10 minutes per day, for a time period of 15 days, the stem cells transformed into Schwann-like cells.

This discovery has made it to the front cover of Advanced Healthcare Materials, a scientific journal. The lead author of the study is Jonathan Claussen, assistant professor of mechanical engineering at Iowa State University and an associate of the U.S. Department of Energys Ames Laboratory. The first authors of the study are Suprem Das, a postdoctoral research associate in mechanical engineering and an associate of the Ames Laboratory, and Metin Uz, a postdoctoral research associate in chemical and biological engineering.

The research has been funded by the Roy J. Carver Charitable Trust, the U.S. Army Medical Research and Materiel Command, and Iowa States College of Engineering, including the Department of Mechanical Engineering. The research has also been supported by The Carol Vohs Johnson Chair in Chemical and Biological Engineering, Surya Mallapragada. She is a co-author of the study, an Anson Marston Distinguished Professor in Engineering, as well as an associate of the Ames Laboratory.

This technology could lead to a better way to differentiate stem cells. There is huge potential here.

Metin Uz

When compared to the standard chemical process with the ability of differentiating only 75% of the stem cells into Schwann-like cells, the highly effective electrical stimulation carried out in the new technique can differentiate 85%. In addition, the electrically differentiated cells generated a nerve growth factor of 80 ng/mm when compared with 55 ng/mm in the case of the chemically treated cells.

The research team believes the outcome might result in changes in the ways nerve injuries are cured inside the body.

These results help pave the way for in vivo peripheral nerve regeneration, where the flexible graphene electrodes could conform to the injury site and provide intimate electrical stimulation for nerve cell regrowth.

The research team

Various benefits of using electrical stimulation for transforming stem cells into Schwann-like cells are reported in the paper:

A graphene inkjet printing process, created in Claussens research lab, is an important part of making the process work. Flexible, inexpensive, and wearable electronics can be produced through the process by making appropriate use of the benefits of wonder-material graphene, namely high stability, high strength, biocompatibility, and higher electrical and heat conductivity.

The research team confronted one major challenge after printing the graphene electronic circuits, the circuits mandated further treatment to enhance the electrical conductivity, normally done using chemicals or high temperatures. Both of these methods can damage the flexible printing surfaces which include paper or plastic films.

Claussen and his colleagues overcame the challenge by developing a computer-controlled laser technology with the ability to selectively irradiate inkjet-printed graphene oxide. This step eliminates ink binders and converts the graphene oxide to graphene by physically connecting millions of tiny graphene flakes together. This improves the electrical conductivity by over a thousand times.

The cooperation between Claussens team of nanoengineers (who developed printed graphene technologies), and Mallapragadas team of chemical engineers (who investigated nerve regeneration), started as a consequence of informal conversations on campus.

This resulted in experimental efforts to grow stem cells on printed graphene and then to perform electrical stimulation experiments.

We knew this would be a really good platform for electrical stimulation. But we didnt know it would differentiate these cells.

Suprem Das

Since the process has been successful in differentiating the stem cells, the scientists believe that there may be further prospective applications to consider. For instance, in future, the technology could be applied to develop absorbable or dissolvable nerve regeneration materials. These could be surgically positioned inside a patients body without the need for subsequent surgery to remove the materials.

Innovative Process for Differentiating Stem Cells into Schwann-Like Cells - AZoNano

(NAPSI)You may be surprised to learn that multiple myeloma is the second most common cancer of the blood, after leukemia. It starts in plasma cells, a type of white blood cell. In time, myeloma cells collect in the bone marrow and may damage the solid part of the bone and eventually harm other tissues and organs, such as the skeleton and the kidneys.

In fact, there are approximately 114,000 new cases diagnosed every year. If you or a loved one is among the 230,000 people living with multiple myeloma worldwide there are a few facts you should know.

What Can Be Done

For many people with the disease, an autologous stem cell transplant may be an answer for eligible patients. This involves collecting the patient's own blood-forming stem cells and storing them. He or she is then treated with high doses of chemotherapy or a combination of chemotherapy and radiation. This kills cancer cells but also eliminates the remaining blood-producing stem cells in the bone marrow. Afterward, the collected stem cells are transplanted back into the patient, so the bone marrow can produce new blood cells.

To help people learn more about the disease and its treatments, the Multiple Myeloma Journey Partners Program was created.

This peer-to-peer education program for patients, caregivers and health care providers leverages storytelling as a tool to improve the patient experience. Journey Partners are multiple myeloma patients who have experienced similar emotions, faced the same challenges and asked the same questions about living with the disease. A Multiple Myeloma Journey Partner will come to any community in which 10 or more people would like to attend the free one-hour educational seminar. The main benefit is that multiple myeloma patients know they're not alone, and the program provides educational resources and services that help patients and families navigate their journey to achieve the best possible outcomes.

As John Killip, a Multiple Myeloma Journey Partner, puts it, "It was conversations with my support group, family and health care providers that influenced my decision to have a stem cell transplant in 2008, when I was first diagnosed with multiple myeloma, at the age of 65. Mentoring other multiple myeloma patients is one of the highlights of my life. I became a Journey Partner to share my story and help others with the disease make sense of the diagnosis and overcome the fear of the unknown."

For more information or to request a program, you can visit http://www.mmjourneypartners.com. Anyone interested in becoming a Multiple Myeloma Journey Partner can contact the program coordinator listed on the website. The program is sponsored by Sanofi Genzyme, the specialty care global business unit of Sanofi focused on rare diseases, multiple sclerosis, immunology, and oncology.

Newswise Hematologist-oncologist Ahmad Samer Al-Homsi MD, MBA, will lead a new bone marrow transplantation program at NYU Langones Perlmutter Cancer Center for treating blood-borne cancers, including leukemia, lymphoma and multiple myeloma, and potentially utilize transplantation as an adjunct to immunotherapy for solid tumors. He also will investigate ways to reduce graft-versus-host disease (GvHD), in which immune cells in donated blood and marrow attack the tissues of a recipient.

In addition, Al-Homsi will facilitate NYU Langones collaboration with Johns Hopkins School of Medicine to institute haploidentical transplantation at PCC, in which less perfectly matched individuals can serve as donors. The advent of haplo-transplantation at Perlmutter Cancer Center will vastly expand the potential donor pool for patients who require a transplant.

Al-Homsi, who officially joins NYU Langone on June 1, 2017, most recently co-founded the blood and bone marrow transplantation program at Spectrum Health, a major multi-site health system in West Michigan. Prior to joining Spectrum, he was chief of the Division of Hematologic Malignancies & Blood and Marrow Transplantation and director of the stem cell laboratory at Roger Williams Medical Center in Providence, RI, an academic affiliate of Boston University School of Medicine. Al-Homsi also directed the blood and marrow transplantation program and held several clinical and academic posts at the University of Massachusetts and its affiliated medical center.

Al-Homsis research is focused on preventing GvHD, a potentially life-threatening complication of bone marrow transplantation. He has led clinical trials examining innovative combinations of medications to prevent GvHD , including cyclophosphamide and proteasome inhibitors. Such combinations can omit the need for extended and burdensome prophylactic traditional agents and are applicable to patients with limited kidney function who are often denied blood and marrow transplantation.

At Perlmutter Cancer Center, Al-Homsi will work closely with a strong hematology-oncology team that has made important advances in the study and treatment of blood-borne cancers. Patients requiring bone marrow transplantation undergo their treatment at the medical centers Rita J. and Stanley H. Bone Stem Cell/Bone Marrow Transplant Center.

His appointment also complements important programmatic and research efforts underway at NYU Langones Transplant Institute.

Our understanding of hematologic malignancies has advanced greatly over the past decade, to the point that many cases are curable, says Benjamin G. Neel, MD, PhD, director of Perlmutter Cancer Center. Bone marrow transplantation plays a critical role in these advances -- but it doesnt come without risk. Dr. Al-Homsis research holds tremendous promise to curtail negative interactions between host and transplanted cells and make this form of treatment safer and more effective.

About Dr. Al-Homsi

Al-Homsi earned his medical degree from the University of Damascus in his native Syria. He received training in Hematology at the University of Tours in Paris and in Clinical Oncology from the University of Paris VI in France. He then completed his training in the United States, serving an internship and residency in Internal Medicine at Christ Hospital and Medical Center in Oak Lawn, Illinois, and a fellowship in Hematology and Medical Oncology at the University of Massachusetts Medical Center.

His published studies have appeared in Transplantation, Leukemia, Transplant Immunology, Journal of Infectious Diseases, International Journal of Molecular Medicine, Bone Marrow Transplantation, and Biology of Blood and Marrow Transplantation. He also has authored many book chapters and review articles, and has served on editorial boards of several peer-reviewed journals in his medical specialty.

Al-Homsi also is a lead inspector for the Federation for the Accreditation of Cellular Therapy (FACT) and a member of its Clinical Standard Sub-Committee and Outcomes Improvement Committee.

I am delighted to join NYU Langone and its Perlmutter Cancer Center to build a nationally recognized bone marrow transplantation program, Al-Homsi says. We are defeating leukemia, lymphoma and myeloma at increasing rates. At the same time, we must continue to discover ways to ameliorate problems that sometimes come with treatment. I am confident we can make important strides.

KEWANEE -- Miss You Can Do It believes she can do it again.

Abbey Curran, diagnosed with cerebral palsy at birth, founded the annual Miss You Can Do It pageant in 2004 for girls and young women with special needs.

She now facesa different type of challenge; searching for a bone-marrow match for her dad, Mike Curran, of Kewanee. Mr. Currant was diagnosed with leukemia and is receiving inpatient chemotherapy at the OSF St. Francis Medical Center in Peoria.

Ms. Currant is working with the Be the Match Registry seeking a bone-marrow match for her father. She also is planning two "drives" to find a match -- the first, 4-8 p.m. April 9 at Raelyns Pub & Eatery, 217 N. State St., Geneseo, and a secondm 2-7 p.m. April 15 at Cernos Bar & Grill, 213 W. 3rd St., Kewanee. Both will offer free refreshments.

Ms. Curran said the "Be the Match Registry is run by the National Marrow Donor Program to help facilitate bone marrow and blood stem cell transplants. The group coordinates national and international medical facilities in marrow transplantation.

Joining me in this effort -- by coming to the drive, helping to save lives -- is easy to do, Ms. Curran said. It will not cost participants a single penny. But all participants will get free food, cake and beer. All that is required for this first step in the process involves a cheek swab and filling out a bit of paperwork.

Participants must be 18 to 60 years old, in good health and willing to donate to any person, Ms. Curran said.The actual marrow donation usually happens through an automated process; in some cases it involves minor surgery under anesthesia at no cost to the donor.

Out of six siblings and myself, my father hasnt found a bone-marrow match, she said. I look at this as another challenge -- another impossible that I need to make possible.

When Ms. Curran learned neither she nor any of her fathers relatives were a bone marrow transplant match, she decided to not only help her father but others desperate to find bone-marrow matches. Determination is a natural trait for Ms. Curran.

My life has been full of challenges and I have taken pride in making the impossible possible, the unrealistic realistic, and I plan to do the same in finding a bone-marrow match for my Dad, she said. "I will find a match and I hope I get hundreds of people to attend these upcoming 'Be the Match events. I am preparing for them.

"I grew up the 'hog farmers daughter from Henry County, she said. I was also born with cerebral palsy. I have always had big dreams and set out to make the impossible possible.

"When I was told I couldnt and shouldnt be the Henry County Fair Queen, I made history by being the first and only woman with a disability to ever make it to Miss USA, as I won Miss Iowa USA in 2008.

Daughter seeks bone marrow match for her dad - Quad-Cities Online

NEWMARKET Karen Olivier is excitedly looking forward to what she calls her stem cell birthday.

Olivier, 40, is traveling April 23 to Monterrey, Mexico, to undergo a procedure that will reset her immune system and stop the inflammation in her body, caused by her relapsing-remitting multiple sclerosis.

Diagnosed with MS at the age of 24, Olivier learned about a treatment called hematopoietic stem cell therapy, or HSCT, from a Facebook page. It gave her hope that if she had this treatment, it would stop the progression of the disease.

She began blogging about her journey leading up to her trip to Mexico.

I want others to know this is an option, she said.

According to the National Multiple Sclerosis Society, HSCT attempts to reboot the immune system, which is responsible for damaging the brain and spinal cord in MS. In HSCT, hematopoietic (blood cell-producing) stem cells are derived from the persons own bone marrow or blood, are collected and stored, and the rest of the individuals immune cells are depleted by chemotherapy.

The stored hematopoietic stem cells are then reintroduced to the body. The new stem cells migrate to the bone marrow and, over time, produce new white blood cells. Eventually they repopulate the body with immune cells, building a new immune system that doesnt know what MS is.

In early clinical trials, 78 percent of participants experienced no new disease activity after the procedure and did not need disease-modifying therapies to control their disease.

Olivier had been taking disease modifying drugs, or DMDs, for 15 years, starting with Avonex, a once weekly intramuscular injection. She then took Rebif, a subcutaneous injection three times a week. After she took a daily injection of Copaxone. In 2009, she started on Tysabri, receiving an infusion every 28 days.

I did well on the Tysabri, but in the past couple of years, my symptoms progressed and my most recent MRI showed new disease activity on my thoracic spine, Olivier said. At the rate my MS was progressing, I would probably be in a wheelchair in two years.

Since 1993, the Federal Drug Administration has approved DMDs to treat relapsing-remitting MS. All are designed to suppress the immune system to one degree or another. These drugs cost about $5,000 per month and they must be taken indefinitely, since relapses will occur if the drugs are stopped.

Oliviers insurance covered the cost of the drugs, but her copays and coinsurance amounts were still very high, she said. One month of a DMD infusion can cost between $7,000 and $9,000.

Olivier researched a clinical trial of HSCT in Chicago, a program begun in 1996 by Dr. Richard Burt, now chief of the division of medicine-immunology and autoimmune diseases at Northwestern Universitys Feinberg School of Medicine.

Trial criteria included relapsing-remitting MS, and failure on at least two DMDs and two flare-ups in the past 12 months, requiring treatment from steroids, she said.

In the United States, HSCT can cost between $150,000 and $200,000.

Insurance may have covered it out-of-network, but my plan has a substantial out-of-pocket maximum, Olivier said. It would have require multiple trips to Chicago for several years, and I could have ended up in the control group.

Olivier began to explore receiving HSCT in other countries and decided to apply for the treatment at Clinica Ruiz in Mexico last October when she was recovering from a flare-up. Clinica Ruiz is based in Pueblo, Mexico, but has expanded to a second clinic in Monterrey.

She and her husband, Jason, agreed spend the $54,500 out-of-pocket cost for the outpatient treatment that also includes transportation to and from a two-bedroom apartment where she will stay for 28 days. Her mother is traveling with her, as the treatment protocol requires the patient to have a caregiver present.

I was accepted based on my MS history and my expanded disability status scale (EDSS) score that basically measures how mobile you are, Olivier said.

Olivier will undergo two days of chemotherapy to wipe out her immune system. She will then have seven days of injections to promote stem cell growth, after which stem cells will be harvested from her blood.

Ill then have two more days of chemotherapy, she said. Im excited. No chemo, no cure.

May 7 will be what Olivier calls her stem cell birthday when she receives her stem cells back to reboot her immune system. She will then be in isolation in the apartment for about a week. Her mother will have to wear special precaution gear during that time.

Some people see improvements in the first three months, with full recovery in two years, Olivier said. Some might say Im not sick enough for this treatment, but the earlier someone gets it, the better, before the MS causes major damage.

She added that some people believe this is a risky procedure and it has not been FDA-approved yet in the United States.

But many people have died on Tysabri and the drug approved by the FDA last week, Ocrevus, has an increased risk of cancer after two to three years. I am hoping the HSCT will stop the progression of my MS, and hope that I never have to go on another DMD in my life.

MARQUETTE, Mich. (WLUC) - UP Health System Marquette will host a bone marrow registry drive on April 12th, 2017 on the 3rd floor of the North Entrance to the hospital.

Every four minutes, someone is diagnosed with a blood cancer in the US. For thousands of patients with leukemia or other blood diseases like sickle cell anemia, a marrow transplant is their only hope.

Joining the bone marrow registry takes roughly 10 minutes of paperwork and a cheek swab. Only 1 in 430 registry members go on to donate. If you match with a patient in need, you will receive a phone call asking to donate. Donation is always voluntary. Surgery is not always required for bone marrow donation; almost 80% of donors donate their blood stem cells in a non-surgical procedure that is very similar to donating plasma.

Please note that UP Health System - Marquette is not affiliated with the National Marrow Donor Program or the Be The Match organization. Our presence here will be to help facilitate and educate those interested in joining the Be The Match registry.

Be The Match is operated by the National Marrow Donor Program (NMDP) which manages the largest and most diverse marrow registry in the world, working to save lives through transplant.

The only practical way to scale-up volumes of mesenchymal stem cells (MSCs) is by using microcarriers in single-use bioreactors, say scientists from A*STAR and Instituto Superior Tcnico.

MSCs are multipotent stromal cells that can differentiate into a variety of cell types which are being investigated for tissue engineering and cellular therapies.

Such cells come from bone marrow, adipose tissue and umbilical cord blood but are very rare, according to Ana Fernandes-Platzgummer, a research scientist for the Stem Cell Engineering Research Group at the Instituto Superior Tcnico in Lisbon, Portugal.

Totipotent cells can form all the cell types in a body, plus the extraembryonic, or placental, cells. The only totipotent cells are embryonic cells within the first couple of cell divisions after fertilisation.

Pluripotent cells can give rise to all of the cell types that make up the body. While embryonic stem cells are considered pluripotent, this class includes induced pluripotent stem cells (iPSC) derived from skin or blood cells that have been reprogrammed back into an embryonic-like pluripotent state.

Multipotent cells are more limited than pluripotent cells but can develop into more than one cell type. This class includes mesenchymal stem cells (MSCs) derived from bone marrow, adipose tissue and umbilical cord blood, and hematopoietic stem cells (HSCs) derived from mesoderm and located in the red bone marrow.

There are only about 100,000 stem cells in an umbilical cord, she told delegates at the 1st Stem Cell Community day in Germany this week. For cellular therapies we need doses of more than one million cells per kg [ideal (IBW) or actual (ABW) body weight] so we need to expand these cells.

Scale-up challenges

Stem cells can be successfully cultivated using flasks and labscale-volume bioreactors but there are many problems in monitoring and controlling growth, and issues with productivity and cell harvest. Therefore scale-up is a problem, hindered further due to a lack of technologies and processes available to cell therapy makers.

The event in Hamburg organised by bioprocessing tech firm Eppendorf looked to address these challenges in stem cell cultivation and scale-up by bringing together industry and academia.

And Fernandes-Platzgummer said that research by the Instituto Superior Tcnico together with Thermo Fisher-owned Life Technologies showed positive results in the expansion of human MSCs from different sources using a fully-controlled stirred-tank bioreactor combined with microcarrier technology.

The advantage of this is its easy scalability, the high surface area [of the microcarrier], the ability to monitor and control cultivation, and the reduced labour costs and risks of contamination, she said.

After five days cultivation the team produced clinically-relevant cell numbers, she added, using an 800ml spinner flask bioreactor, Thermo Fishers serum-free medium StemPro and reagent TrypLE Select CTS, and plastic microcarriers coated with the xeno-free substrate CELLstart (also made by Thermo Fisher).

'10,000 doses per year, each of a billion cells'

In a separate presentation, Steve Oh principal scientist and associate director at the Bioprocessing Technology Institute (BTI), part of Singapores Agency for Science, Technology and Research (A*STAR) said a similar set-up had shown promise in moving MSC cultivation into scalable technologies and his team is trying to move to a 15L scale.

However, the goal for MSC-based therapies would be producing commercial volumes of 10,000 doses per year, each of a billion cells from the onset, he added.

We looked at all the approaches and really the only practical experience I have of a technology that will succeed is microcarrier technology using single-use bioreactors, he said.

Oh added microcarriers produce higher cell densities with the same amount of media while allowing greater control of the process by providing another metric to configure.

Furthermore, having only thin layers of cells between each carrier offers benefits in the harvesting of stem cells which he said is as problematic as cultivation due to the large aggregates of cell clusters formed which are difficult to break up.

BROOKLINE Fighting for her life, a retired Brookline teacher who has been struggling with cancer for more than four years is hoping to find a donor for a stem cell transplant.

This week, Kathi Bond of Temple has undergone 96 hours of around-the-clock chemotherapy, but next week provides a new and unique opportunity for the 66-year-old woman battling a bone marrow cancer known as multiple myeloma.

A marrow donor registry drive will take place on Tuesday in an effort to find a match for Bond, who has undergone numerous, unsuccessful therapies throughout the past several years.

She is not the type that wants to be lying in a bed staring at a blank wall she would rather be climbing mountains, said Bonds husband, David Bond. She is a very vibrant woman, but on paper she is very ill.

Kathi Bond, who retired in 2013 from her environmental science teaching position in the Brookline School District because of the cancer, has already undergone an autologous stem cell transplant where her own cells were used for the procedure.

While this effort placed her in remission for more than a year, her body eventually began to reject the treatment and she fell ill again in the fall of 2016, and is now at stage 3 multiple myeloma.

I think emotionally, for any cancer patient, it is a roller coaster, said David Bond. You have good days and bad days glimmers of light and then news that things arent working.

Multiple myeloma is a plasma cell disorder that attacks cells in a persons bone marrow. Since traditional treatments are not working for Kathi Bond, doctors are now looking for radical ways to preserve her life, and a donor transplant is the next alternative.

Unfortunately, at this point, they have not found a match for Kathi, said her husband. But we have always felt that optimism is stronger than adversity. There will be a match out there somewhere.

A marrow donor registry drive will take place from 3:30 p.m. to 7 p.m. Tuesday at the Richard Maghakian Memorial School, 22 Milford St. in Brookline. Participants must be ages 18 to 44, and will have their cheek swabbed to determine compatibility.

Kathi Bond, who is currently hospitalized, is attempting to reduce the number of myeloma cancer cells in an effort to make the future transplant more successful. She is working with an oncologist in Nashua, and the Dana-Farber Cancer Institute to determine the best course of action for an incurable illness.

She is fairly strong right now, but a transplant is desperately needed, said David Bond.

Cancer is no longer a private struggle, he said, adding it affects so many families. In 1984, Kathi Bond lost her older sister to lymphoma.

At the time, he said there were no donor drives, walks for cancer or fundraisers to research cancer treatments.

Today, we save lives because we share our story, and compassionate people step forward and join the fight, he said.

The Bonds are hopeful to find a match from next weeks marrow donor registry drive, but said even if they dont, the data may be useful in helping to find a match for someone else in desperate need.

Kathleen Milewski, a second-grade teacher at RMMS in Brookline, along with the Bonds two daughters, have been instrumental in helping to organize Tuesdays drive, according to David Bond.

Joining the registry is as simple as a cheek swab, and the donation process, should you be a match, is similar to giving blood in over 70 percent of the cases, said Milewski. Kathi needs a match in order to continue to live with multiple myeloma.

David Bond said a donor transplant is his wifes greatest hope for a life of near-normalcy. A donors stem cells will result in a total reboot of the patients marrow, and as new donor stem cells develop and mature, they will over-populate the bad cells.

NEW YORK (CBSNewYork) Theres potentially exciting news for the two and a half million people around the world struggling with multiple sclerosis.

There is no known cure, but now an experimental treatment in Israel may be able to reverse the symptoms, CBS2s Dr. Max Gomez reports.

MS is a progressive degenerative disease where the insulation around nerve fibers in the brain and spinal cord starts to break down. Its the immune system attacking the insulation.

Medications can slow the disease but dont stop it. Stem cells may be much better.

As Dr. Max reports, walking on a treadmill is a big step for Malia Litman. She had been a top trial attorney in Dallas until she was diagnosed with multiple sclerosis 18 years ago. Slowly, the disease robbed her of her balance, her mobility and her energy.

You can imagine how contracted my world had become, she says.

After she fell and broke her leg, she was in a wheelchair for weeks. Her MS medicines werent really working anymore.

Her search for alternative treatments led toDr. Dimitrios Karussis.

Answers for our diseases and our medical problems are hidden inside our body, hesays.

Karussis heads the experimental stem cell research atHadassah Medical Organization in Israel. He harvests an MS patients own adult stem cells from their bone marrow, then injects them back into their spinal fluid.

As neurologists, we have never seen or even believed that it is possible to reverse any disability, he says.

Litman says within 24 hours of her first treatment, I picked up my leg and went, Oh my god, and I just started crying.

She says her speech is more clear and she has more energy, and shes adamant its not a placebo effect, pointing to a number of tests before and after treatment that show improvement.

Karussis says one patient was even able to walk again.

Researchers are now collaborating with teams at the Mayo Clinic and Harvard, finishing a double-blind study to prove its effectiveness.

Look what I can do now! Its amazing, Litman says.

She still uses her walker but can now get on her rowing machine. After four treatments, shes reactivated her law license and is taking on a case.

I feel like I have my life back. I dont care if I walk with a walker the rest of my life. Although I think I may actually be able to walk again with a couple more treatments, she says.

As Dr. Max reports, the theory is that the stem cells are somehow spurringthe regeneration of the insulating nerve sheaths that are deteriorating in MS.

However, the course of the disease is so variable that Litmans improvement may not be due to the stem cell treatment. Thats why the double-blind studyis so important.

Hadassah Medical Organizations researchers are also looking at the treatments effect on ALS patients.

Experimental Stem Cell Treatment Might Reverse Symptoms Of Multiple Sclerosis - CBS New York

Scientists report another step in the use of stem cells to help treat people with debilitating heart failure.

In an early study of 27 patients, Japanese researchers used patients' own muscle stem cells to create a "patch" that was placed on the heart.

Over the next year, the patients generally showed small improvements in their symptoms -- including the ability to walk without becoming breathless and fatigued.

However, experts cautioned that while the results are encouraging, there's a lot of work left ahead before stem cells can be used to treat heart failure.

"They've shown that this approach is feasible," said Dr. Eiran Gorodeski, a heart failure specialist at the Cleveland Clinic in Ohio.

But it's not clear whether the stem-cell tactic was actually effective, said Gorodeski, who was not involved in the study.

RELATED: Antidepressant No Help to Heart Failure Patients

That's because the study didn't include a comparison group that did not receive stem cells.

So it's possible, Gorodeski explained, that the "modest" symptom improvements would have happened anyway. All of the patients were on standard medications, and some had heart devices implanted.

Stem cells are primitive cells that mature into the various cells that make up the body's tissues. In the past 15 years or so, scientists have tried to use the cells to help repair some of the damage seen in heart failure.

Heart failure is a progressive disease where the heart muscle is too damaged to efficiently pump blood throughout the body. It often arises after a heart attack.

Symptoms of heart failure include fatigue, breathlessness and swelling in the limbs. The condition cannot be cured, although medications and implantable devices can treat the symptoms.

In the new study, the researchers used stem cells from the patients' own thigh muscle to create a patch they placed on the heart.

That's in contrast to many past studies, where researchers have injected stem cells -- often from patients' bone marrow -- into the heart.

The patch tactic could have some advantages, said senior researcher Dr. Yoshiki Sawa, of Osaka University.

He said animal research suggests that cells in sheet form survive for a longer period, compared to injections.

To test the safety of the approach, Sawa's team recruited 27 patients who had debilitating symptoms despite standard heart failure therapies. The scientists extracted stem cells from each patient's thigh muscle, then cultured the cells so that they formed a sheet.

The sheet was placed on each patient's heart.

The tactic appeared safe, the researchers said, and there were signs of symptom improvements over the next six months to a year.

Why would stem cells from the thigh muscle affect the heart? It's not clear, Sawa acknowledged.

The stem cells don't grow into new heart muscle cells. Instead, Sawa explained, they seem to produce chemicals called cytokines that can promote new blood vessel growth in damaged areas of the heart. The theory, he said, is that "hibernating" cells in the heart muscle can then function better.

Still, it's too soon to know what the new findings mean, said Gorodeski.

This type of trial, called phase 1, is designed to look at the safety and feasibility of a therapy, Gorodeski said. It takes later-phase trials -- where some patients receive the treatment, and others do not -- to prove that a therapy actually works.

Those trials are underway, Sawa said.

Other studies are further along. Last year, researchers reported on a trial testing infusions of stem cells taken from the bone marrow of patients with severe heart failure.

Patients who received the therapy were less likely to die or be hospitalized over the next year, versus those given standard treatment only. But the study was small, and the stem cells had only a minor impact on patients' heart function.

So it's not clear why the stem-cell patients fared better, Gorodeski said.

For now, he stressed, all stem-cell therapies for heart failure remain experimental.

"There's no cell therapy that we can offer patients right now," Gorodeski said.

The message for patients, he added, is that heart failure can be treated, and researchers are looking for "innovative" ways to improve that treatment.

The study was published April 5 in theJournal of the American Heart Association.

Bone tissue engineering is theoretically now possible at a large scale. A*STAR researchers have developed small biodegradable and biocompatible supports that aid stem cell differentiation and multiplication as well as bone formation in living animal models.

Mesenchymal stem cells self-renew and differentiate into fat, muscle, bone, and cartilage cells, which makes them attractive for organ repair and regeneration. These stem cells can be isolated from different sources, such as the human placenta and fatty tissue. Human early mesenchymal stem cells (heMSCs), which are derived from fetal bone marrow, were thought to be best suited for bone healing, but were not readily accessible for therapeutic use.

Existing approaches to expand stem cells for industrial applications tend to use two-dimensional materials as culture media, but their production yields are too low for clinical demand. Furthermore, stem cells typically need to be harvested with enzymes and attached to a scaffold before they can be implanted.

To bring commercially viable cell therapies to market, Asha Shekaran and Steve Oh, from the A*STAR Bioprocessing Technology Institute, have created directly implantable microscopic spheres in collaboration with the A*STAR Institute of Materials Research and Engineering. These spheres, which acted as heMSC microcarriers, consist of a biodegradable and biocompatible polymer called polycaprolactone.

According to Shekaran, their initial aim was to expand stem cells on microcarriers in bioreactors to scale up production. However, this strategy threw up difficulties, especially when attempting to effectively dissociate the cells from the microcarriers and transfer them to biodegradable scaffolds for implantation.

"A biodegradable microcarrier would have a dual purpose," Shekaran says, noting that it could potentially provide a substrate for cell attachment during scalable expansion in bioreactors, and a porous scaffold for cell delivery during implantation.

The researchers generated their microcarriers by synthesizing polycaprolactone spheres and coating them with two proteins polylysine and fibronectin. These proteins are found in the extracellular matrix that assists cell adhesion, growth, proliferation, and differentiation in the body.

Microcarriers that most induced cell attachment also promoted cell differentiation into bone-like matrix more strongly than conventional two-dimensional supports. In addition, implanted stem cells grown on these microcarriers produced an equivalent amount of bone to their conventionally-derived analogs.

"This is encouraging because microcarrier-based expansion and delivery are more scalable than two-dimensional culture methods," says Shekaran.

The team now plans to further investigate the therapeutic potential of these microcarrierstem cell assemblies in actual bone healing models.

Jonathan Pitre rests in bed, his pillow with his Boston terrier, Gibson, on it close by. Tina Boileau / -

As he continues high-dose chemotherapy in advance of his second stem-cell transplant, Jonathan Pitre is keeping his dog, Gibson, close to his heart.

Pitre, 16, is wearing a glass pendant with a picture of his Boston terrier throughout his days in the University of Minnesota Masonic Childrens Hospital.

He says that having it around his neck except for sleeping gives him strength even in the darkest moments, said his mother, Tina Boileau, who had the pendant made for him one day after he entered the hospital.

It was the only thing he really wanted, Boileau said.

Pitre is in Minnesota for his second stem-cell transplant, seven months after the first one failed to engraft. Usually, patients undergoing a second transplant so soon after the first do not receive full doses of chemotherapy and radiation because their immune systems are already weakened.

Jonathan Pitre wears his glass pendant that has a picture of his Boston terrier, Gibson, in it. His mom had the pendant made for him after he entered the hospital. Tina Boileau / -

But doctors are taking no chances with Pitre.Hes receiving eight days of high-dose chemotherapy and one day of full-body radiation the same regimen as his first transplant in order to increase the probability of success.

The conditioning regimen is necessary to destroy Pitres bone marrow cells so that the transplanted cells will have room to grow; it also suppresses Pitres immune system so that it doesnt attack the donated stem cells.

Blood tests show Pitre has not developed antibodies to combat another infusion of stem cells from his mother, the original donor. It means Boileau can again serve as the stem cell donor when the transplant takes place on April 13.

As part of the conditioning regimen, doctors are also infusing Pitre withantithymocyte globulin (ATG), a drug designed to further suppress the immune system by acting against specific white blood cells that can attack bone marrow stem cells.

On Thursday, Pitre was three days into the nine-day regimen. Boileau said hes had a low-grade fever, but has otherwise tolerated the treatment well.

He is as strong mentally and physically as he can be, Boileau said. If anything, hes fighting even harder this time; hes really focused on making this transplant work.

Pitrebelieves his incredible willpower might be able to operate on a cellular level, and he has vowed to direct his own cells to co-operate with his mothers stem cells.

Pitre is the first Canadian to take part in the clinical trial operated by the University of Minnesotas Dr. Jakub Tolar, a pediatric transplant specialist who has adapted stem-cell therapy as a treatment for the most severe forms of epidermolysis bullosa (EB).

Pitre suffers from recessive dystrophic EB, a rare, painful and deadly form of the blistering skin disease.

Although the transplant can be accompanied by life-threatening complications, it is the only EB treatment that holds the potential to dramatically improve the condition. Two-thirds of theEB patients who have survived the transplant have experienced reduced blistering and better wound healing.
