STAP cells paper coauthor asks for retraction
By NEVAGiles23
Mouse cells exposed to an acidic environment turned into embryonic-like "STAP" cells. These were used to generate an entire fetus.
A coauthor of a disputed study on a new way generating stem cells through exposure to acid and other stresses has asked for its retraction, it was reported Monday.
Teruhiko Wakayama asked for retraction of two papers describing so-called STAP cells, according to the Yomiuri Shimbun. The papers had been published in the Jan. 30 edition of the journal Nature. Other news outlets, including the Wall Street Journal and the Boston Globe, quickly followed up with the call for retraction.
The original announcement gained worldwide attention because it promised an easy way to generate pluripotent stem cells, which act like embryonic stem cells. Simply immersing cells in an acid bath or squeezing them was enough to reprogram them to the embryonic-like state, the scientists reported. The acronym STAP stands for stimulus-triggered acquisition of pluripotency.
However, researchers attempting to replicate the experiment, including those at the Salk Institute and The Scripps Research Institute in La Jolla, have so far reported failure. And errors in the papers, including duplication of images, have caused scientists to question the findings.
The first author of both papers is Haruko Obokata, 30, of the Riken Center for Developmental Biology in Japan. She was hailed as a scientific prodigy after the research was published. Another coauthor, Charles Vacanti, chairman of the Anesthesiology department at Brigham and Womens Hospital in Boston, had previously said the errors were caused by overwork and didn't affect the results.
As recently as Feb. 27, Wakayama said scientists should give replication efforts a year before passing judgment.
But on Monday, Wakayama said the irregularities render the findings questionable.
"Wakayama said images that show pluripotency of STAP cells look almost identical to those used in Obokatas doctoral thesis about pluripotent stem cells that exist in human body," the Yomiuri Shimbun reported.
Wakayama is probably acting out of a sense of duty, said Jeanne Loring, a stem cell scientist at The Scripps Research Institute.

STAP cells paper coauthor asks for retraction
Stem Cell Researcher Suggests Recalling His Own Study
By LizaAVILA
By Maggie Fox
One of the worlds leading stem cell experts has suggested withdrawing a study that made global headlines last January, saying he has questions about some of the images and data in it.
The Japanese team, led by Teruhiko Wakayama, reported that they had created powerful stem cells by doing little more than soaking ordinary cells in an acid solution.
The report, published in the journal Nature, impressed other stem cell researchers and opened the possibility of an easy approach to regenerative medicine. But Japanese television quotes Wakayama as saying he wants to take a closer look.
"When conducting the experiment, I believed it was absolutely right, Reuters news agency quotes Wakayama as telling the television station NHK.
"But now that many mistakes have emerged, I think it is best to withdraw the research paper once and, using correct data and correct pictures, to prove once again the paper is right," he said.
"If it turns out to be wrong, we would need to make it clear why a thing like this happened."
But Charles Vacanti of Harvard Medical School and Brigham and Women's Hospital in Boston, who helped work on the study, said he disagreed. "Some mistakes were made, but they don't affect the conclusions," the Wall Street Journal quoted him as saying.
"Based on the information I have, I see no reason why these papers should be retracted."
Stem cell researchers may be more sensitive than other scientists. In 2006, Seoul National University fired Hwang Woo-Suk after the journal Science retracted two papers he wrote claiming to have cloned human embryos and extracted stem cells from them.

Stem Cell Researcher Suggests Recalling His Own Study
Blood, marrow transplants must be kept accessible
By NEVAGiles23
The recent news of veteran TV journalist Tom Brokaw being diagnosed with multiple myeloma sparked interest in this rare form of cancer. Approximately 20,000 people are diagnosed annually with multiple myeloma cancer of the plasma cells in the bodys bone marrow. These abnormal plasma cells dont produce antibodies, so the immune system cant fight off infections.
Like Brokaw, who is 74, the majority of people diagnosed with multiple myeloma as well as more common blood cancers such as leukemia and lymphoma are older than 65. That means that many of these patients depend on Medicare to pay for their treatment, which often includes a blood or bone marrow transplant (BMT).
Ten years ago, patients older than 55 were commonly excluded from this treatment option. Today, because of medical advances, the Medicare population is the fastest-growing segment of patients in most BMT programs in the United States.
However, because of Medicare coverage restrictions, many patients who need a transplant are unable to receive treatment unless they are in the financial position to pay privately for their care.
The financial burden is even more significant when a transplant requires the use of donated stem cells, often needed for those with blood cancers such as leukemia and lymphoma. Because of a difference in the way that Medicare reimburses hospitals for BMT in comparison with solid organ transplantation, each BMT using donor cells results in a substantial financial loss to the hospital providing care.
The financial loss per transplant case is large enough that it is unsustainable, cannot be offset by private insurance payments and is threatening our ability to continue to deliver this vital therapy to those who need it most.
Our clinical success in finding ways to treat older patients has created an unfortunate, but very real, financial threat to the continued existence of our field. In December, we began a dialogue with our partners at Medicare to remedy this situation and hope that continued discussions will result in a correction of the rate-setting methodology currently used.
We are mindful that BMT is an expensive therapy. There is no question that expert teams and significant resources are required. But it is also a lifesaving therapy. Currently, there are more than 100,000 transplant survivors in the United States. With continuing advances in the use of transplant, we project 250,000 by 2020 and 500,000 by 2030 with a quarter of the survivors being over 60 years old.
These costs would not disappear if this treatment were not available. The costs of providing alternate therapies that do not have the potential to be curative are significant. Older patients deserve continued access to therapies that will provide them with the best chance of enjoying more well-earned years of high-quality life with their families and friends.
This month, the American Society for Blood and Marrow Transplantation (ASBMT) celebrates 20 years since its founding. We represent nearly 2,000 transplant clinicians and health care professionals worldwide. Recently we gathered in Dallas for our annual meeting to share cutting-edge research and knowledge, continuing our quest to be the best in the world at what we do for the sake of our patients.

Takeda and UCL to work together to tackle muscle disorders
By Sykes24Tracey
PUBLIC RELEASE DATE:
9-Mar-2014
Contact: Henry Rummins h.rummins@ucl.ac.uk 44-207-679-9063 University College London
Japanese pharmaceutical company Takeda will work with University College London (UCL) to drive research into tackling muscle disorders, in particular muscular dystrophy.
The research which is being conducted by the research group of Dr Francesco Saverio Tedesco is being supported through funding of $250,000 from the company's New Frontier Sciences group. Takeda's NFS aims to support innovative, cutting-edge research which could eventually lead to drug discovery and development.
Dr Tedesco's team will focus on the study of muscular regeneration and the potential for stem cell therapies to treat muscular dystrophy, in particular induced pluripotent (iPS) stem cells.
The team is also investigating the potential for treating muscular dystrophy through developing novel gene and cell therapy strategies using artificial human chromosomes and novel biomaterials.
Using this approach, Dr Tedesco hopes to overcome a number of current limitations to developing effective treatments for muscular dystrophies. It is hoped that through the use of these modified stem cells, large quantities of progenitor cells could be produced to be transplanted into a patient's muscle following genetic correction or to be used for drug development platforms.
Importantly, the team will attempt to produce these cells which can be applied more easily in a clinical context, in order to reduce the hurdles that might limit their possible future use in clinical studies.
Through previous work using a mouse model of Duchenne muscular dystrophy, the team has already demonstrated the potential of pre-clinical gene replacement therapy using an artificial human chromosome.

Stem Cell Center advancing treatments, officials say
By LizaAVILA
Topeka Eight months after the establishment of the Midwest Stem Cell Therapy Center at Kansas University Medical Center, the center is conducting clinical trails and advancing treatments for numerous diseases, KU officials said Monday.
"We are very excited about the work that is going on," said Dr. Doug Girod, executive vice chancellor of the KU Medical Center.
Dr. Buddhadeb Dawn, the center's director, detailed clinical trials that are under way and several in the planning stages to the Senate Ways and Means Committee.
"These trials will help local patients to get access to stem cell therapy," Dawn said. "Kansas can be a leader in providing stem cell treatments."
Created last year by the Legislature and Gov. Sam Brownback, the center will work on adult stem cell, cord blood and related stem cell research, providing therapies to patients and serving as a clearinghouse for physicians on cutting-edge treatments.
The center is prohibited from using embryonic stem cells or cells taken from aborted fetal tissue. Abortion opponents oppose human embryonic stem cell research because it involves the destruction of the embryo.
David Prentice, senior fellow for life sciences of the Family Research Council, said the center was unique in the country.
Prentice, who was involved in the development of the center and is on the center's advisory board as a representative of the scientific community, said, "I do want to reemphasize the focus on the center is patient-centered," while also working on education, clinical trials and research.
The FRC describes itself as a Christian organization promoting the traditional family unit and the Judeo-Christian value system. Its critics say it spreads anti-gay propaganda.
State Sen. Jeff Melcher, R-Overland Park, said the research sounded exciting but that he was concerned that the advisory board had no business people on it to secure private and business funding.

Stem cell center starting trials
By daniellenierenberg
Seven months after a bill to create a regional stem cell therapy hub at the University of Kansas Medical Center took effect, two doctors from the center say it is enrolling patients in clinical trials and beginning their work.
David Prentice and Buddhadeb Dawn expressed excitement over what the Midwest Stem Cell Therapy Center has been able to accomplish in a short time and what possibilities it holds for the future.
"Kansas can be the leader in providing adult stem cell treatments and information to physicians and patients around the world," Dawn said.
Prentice said the center, which limits itself to research on adult stem cells, will foster "ethical, non-controversial" treatments for patients with multiple sclerosis, spinal cord injuries, heart damage, stroke and juvenile diabetes.
At the same time he said it will serve to educate schoolchildren on the promise of adult stem cells and act as a "hub" for regional research.
Potentially physicians from across the region could be sending samples," Prentice said.
Okyanos CEO Matt Feshbach Announces Appointment of Institutes Marketing Executive Erika Rosenthal to International …
By Dr. Matthew Watson
Freeport, The Bahamas (PRWEB) March 10, 2014
Matt Feshbach, CEO of Okyanos Heart Institute whose mission it is to bring a new standard of care and better quality of life to patients with coronary artery disease using cardiac stem cell therapy has announced the appointment of Okyanos senior vice president of marketing, Erika Rosenthal, to the International Stem Cell Society (STEMSO) Advisory Board. She will advise the trade organization in a communications capacity to benefit the membership and the mission.
STEMSO is a member-based, international, non-profit 501(c) 6 trade association which promotes the interests of organizational members of the global, adult stem cell healthcare community. STEMSO provides information, education, resources, advocacy and public awareness for the advancement of adult stem cell research and therapy. The organization recently hosted a global regenerative medicine conference in Freeport, The Bahamas, entitled, Bridging the Gap: Research to Point of Care which brought together experts in adult stem cell therapy and regulations to discuss commercialization of therapies for chronic disease in a safe, ethical, and compliant manner.
STEMSO is an important organization to the field of stem cell therapy and research, said Feshbach. Communications and healthcare are both fields in which Erika excels, and so I am pleased to see her lend her expertise for an important cause. I look forward to the Okyanos Heart Institute executive team continuing with such efforts for the greater good of medicine.
Rosenthal was a 2008 recipient of the National Association of Women Business Owners Business Woman of the Year award, and was recognized in Business Leader Magazine as a Woman Extraordinaire, for her business accomplishments and contributions to the non-profit community. She is a former faculty member of the University of California where she taught Marketing and Hospitality Management.
It is indeed an honor to work with STEMSO to advance their cause to help advance adult stem cell research and therapy worldwide, and to bring together leading researchers, physicians, regulators and scientists to set standards for ethical and responsible delivery of therapies as they become available to the public worldwide, said Rosenthal. It is an exciting time in medicine, and STEMSO is greatly needed to bring collaboration and guidance between this impressive member group of thought leaders.
STEMSO is pleased to have Erika Rosenthal participate on STEMSOs Advisory Board, said Douglas Hammond, president of STEMSO. Non-profit trade associations are only as strong as their member participation and leadership allows. If other members or prospective organizational members were to support STEMSO as Okyanos Heart Institute and Erika Rosenthal, there would be no limit to STEMSOs impact in the Regenerative Medicine Industry.
About Okyanos Heart Institute: (Oh key AH nos) Based in Freeport, The Bahamas, Okyanos Heart Institutes mission is to bring a new standard of care and a better quality of life to patients with coronary artery disease using cardiac stem cell therapy. Okyanos adheres to U.S. surgical center standards and is led by Chief Medical Officer Howard T. Walpole Jr., M.D., M.B.A., F.A.C.C., F.S.C.A.I. Okyanos Treatment utilizes a unique blend of stem and regenerative cells derived from ones own adipose (fat) tissue. The cells, when placed into the heart via a minimally-invasive procedure, can stimulate the growth of new blood vessels, a process known as angiogenesis. Angiogenesis facilitates blood flow in the heart, which supports intake and use of oxygen (as demonstrated in rigorous clinical trials such as the PRECISE trial). The literary name Okyanos, the Greek god of rivers, symbolizes restoration of blood flow.

Stem cell study opens door to undiscovered world of biology

For the first time, researchers have shown that an essential biological process known as protein synthesis can be studied in adult stem cells something scientists have long struggled to accomplish. The groundbreaking findings from the Children's Medical Center Research Institute at UT Southwestern (CRI) also demonstrate that the precise amount of protein produced by blood-forming stem cells is crucial to their function.
The discovery, published online today in Nature, measures protein production, a process known as translation, and shows that protein synthesis is not only fundamental to how stem cells are regulated, but also is critical to their regenerative potential.
"We unveiled new areas of cellular biology that no one has seen before," said Dr. Sean Morrison, Director of the Children's Research Institute, Professor of Pediatrics, and the Mary McDermott Cook Chair in Pediatric Genetics at UT Southwestern Medical Center. "No one has ever studied protein synthesis in somatic stem cells. This finding not only tells us something new about stem cell regulation, but opens up the ability to study differences in protein synthesis between many kinds of cells in the body. We believe there is an undiscovered world of biology that allows different kinds of cells to synthesize protein at different rates and in different ways, and that those differences are important for cellular survival."
Dr. Adrian Salic's laboratory at Harvard Medical School chemically modified the antibiotic puromycin in a way that made it possible to visualize and quantify the amount of protein synthesized by individual cells within the body. Dr. Robert A.J. Signer, a postdoctoral research fellow in Dr. Morrison's laboratory and first author of the study, realized that this reagent could be adapted to measure new protein synthesis by stem cells and other cells in the blood-forming system.
What they came across was astonishing, Dr. Morrison said. The findings suggested that different types of blood cells produce vastly different amounts of protein per hour, and stem cells in particular synthesize much less protein than any other blood-forming cells.
"This result suggests that blood-forming stem cells require a lower rate of protein synthesis as compared to other blood-forming cells," said Dr. Morrison, the paper's senior author.
Researchers applied the findings to a mouse model with a genetic mutation in a component of the ribosome the machinery that makes proteins and the rate of protein production was reduced in stem cells by 30 percent. The scientists also increased the rate of protein synthesis by deleting the tumor suppressor gene Pten in blood-forming stem cells. In both instances, stem cell function was noticeably impaired.
Together, these observations demonstrate that blood-forming stem cells require a highly regulated rate of protein synthesis, such that increases or decreases in that rate impair stem cell function.
"Amazingly, when the ribosomal mutant mice and the Pten mutant mice were bred together, stem cell function returned to normal, and we greatly delayed, and in some instances entirely blocked, the development of leukemia," Dr. Morrison said. "All of this happened because protein production in stem cells was returned to normal. It was as if two wrongs made a right."

Stem cell transplant shows 'landmark' promise for treatment of degenerative disc disease
By daniellenierenberg
Stem cell transplant was viable and effective in halting or reversing degenerative disc disease of the spine, a meta-analysis of animal studies showed, in a development expected to open up research in humans. Recent developments in stem cell research have made it possible to assess its effect on intervertebral disc (IVD) height, Mayo Clinic researchers reported in a scientific poster today at the 30th Annual Meeting of the American Academy of Pain Medicine.
"This landmark study draws the conclusion in pre-clinical animal studies that stem cell therapy for disc degenerative disease might be a potentially effective treatment for the very common condition that affects people's quality of life and productivity," said the senior author, Wenchun Qu, MD, PhD, of the Mayo Clinic in Rochester, Minn.
Dr. Qu said not only did disc height increase, but stem cell transplant also increased disc water content and improved appropriate gene expression. "These exciting developments place us in a position to prepare for translation of stem cell therapy for degenerative disc disease into clinical trials," he said.
The increase in disc height was due to restoration in the transplant group of the nucleus pulposus structure, which refers to the jelly-like substance in the disc, and an increased amount of water content, which is critical for the appropriate function of the disc as a cushion for the spinal column, the researchers concluded.
The researchers performed a literature search of MEDLINE, EMBASE and PsycINFO databases and also manually searched reference lists for original, randomized, controlled trials on animals that examined the association between IVD stem cell transplant and the change of disc height. Six studies met inclusion criteria. Differences between the studies necessitated the use of random-effects models to pool estimates of effect.
What they found was an over 23.6% increase in the disc height index in the transplant group compared with the placebo group (95% confidence interval [CI], 19.7-23.5; p<0.001). None of the 6 studies showed a decrease of the disc height index in the transplant group. Increases in the disc height index were statistically significant in all individual studies.
The authors commented that it is time to turn attention to the much-needed work of determining the safety, feasibility, efficacy of IVD stem cell transplant for humans.
"A hallmark of IVD degenerative disease is its poor self-repair capacity secondary to the loss of IVD cells. However, current available treatments fail to address the loss of cells and cellular functions. In fact, many invasive treatments further damage the disc, causing further degeneration in the diseased level or adjacent levels," said the lead study author Jason Dauffenbach, DO. "The goal of tissue engineering using stem cells is to restore the normal function and motion of the diseased human spine."

Bone Marrow Transplant Program at Seattle Cancer Care Alliance Recognized for Its One-Year Survival Rates
By Sykes24Tracey
Contact Information
Available for logged-in reporters only
Newswise SEATTLE The Fred Hutchinson Bone Marrow Transplant Program at Seattle Cancer Care Alliance (SCCA) was recently recognized by the Center for International Blood and Marrow Transplant Research (CIBMTR) for outperforming its expected one-year survival rate for allogeneic transplant patients. The results published by the CIBMTR, analyzed the National Marrow Donor Programs (NMDP) registry of 168 U.S. transplant centers over a three-year period for its 2013 Transplant Center-Specific Survival Report.
The Fred Hutchinson Bone Marrow Transplant Program at SCCA pioneered the clinical use of bone marrow and stem cell transplantation more than 40 years ago and have performed more than 14,000 bone marrow transplants more than any other institution in the world. Today, the organization is one of just 13 stem cell transplant programs nationwide that exceeded its anticipated one-year survival rate for patients undergoing allogeneic transplants.
This type of transplant uses stem cells from a donor who may or may not be related to the patient. Stem cell transplants, including bone marrow transplants, are used to treat a range of leukemias and lymphomas, as well as other diseases such as severe aplastic anemia and sickle cell disease.
Comparing Transplant Centers
Comparing transplant centers in the U.S. is an extremely challenging process, explains Dr. Marco Mielcarek, medical director of the Adult Blood and Marrow Transplant Program at SCCA. There are so many variables that must be taken into account, including type of cancer and stage, the patients underlying medical problems and age, the type of transplant they undergo, and the source of the stem cells for the transplant. Each patient has a unique risk profile.
Although the process of comparing transplant centers can be challenging, the intensive analysis allows researchers to compare themselves to other centers, leading to improved outcomes. Additionally, the report provides patients and their families with valuable information necessary when evaluating where to go for treatment.
When you adjust for risk factors, our patients outcomes exceeded expectations over a three-year period, Dr. Mielcarek says, thats information that is helpful for patients to know when they are making important health care decisions with their families.
To arrive at its findings, CIBMTR independently examined the survival rates of 19,945 transplants performed to treat blood cancers at U.S. centers in the NMDP network. The most recent reporting period covered January 1, 2009 to December 31, 2011. During this three-year period, 762 allogeneic transplants were performed at SCCA. The report, published annually, is required by federal law and is designed to provide potential stem cell transplant recipients, their families, and the public with comparative survival rates among transplant centers.

Stem Cells Driving Alzheimer's Research
By raymumme
By Marcus Johnson
Stem cell researchers from Harvard have been able to turn patients skin cells into neurons that can be affected by early-onset Alzheimers. Experts believe that this will make it easier to gather the results of cells affected by the disease. It is also believed that the research will make the development of new treatments a faster process.
The research was published in the Human Molecular Genetics journal and headed by Tracy Young-Pearse. The data showed that peopl suffering from Alzheimers had cell mutations t similar to mutations occurring in mice. We see this mild increase in A42 in cells from patients with Alzheimer's disease, which seems to be enough to trigger disease processes, said Young-Pearse. We also see increases of a smaller species of amyloid-beta called A38, which was unexpected as it should not be very aggregation prone. We don't fully understand what it means, but it may combine with other forms of amyloid-beta to stimulate plaque formation.
The researchers hope that their work can lead to new drugs that are more effective against the disease. Alzheimers drugs have had a high rate of failure during clinical trials because much of the drug development was based on non-human models. Young-Pearse hopes that their research can make it easier to treat the disease and develop new drugs. Because of the Harvard Stem Cell Institute, we were able to work with other researchers to make patient cells into any type of neuron," said Young-Pearse. "The environment provides a really nice system for testing many kinds of hypotheses.

Guidelines on use of stem cell therapy
By LizaAVILA
Google stem cell therapy and a whole host of results show up. Stem cell therapy for hair loss, diabetes, cancer and practically everything else. It is touted as the medicine of hope, the panacea for all ills.
But to ensure that this potentially-powerful technology is not misused in the country, the Indian Council of Medical Research has come up with a set of guidelines to regulate their use.
Under the new guidelines, any use of stem cells in patients will be considered research, not therapy.
This means stem cells can now only be used on patients within the purview of an approved, and monitored clinical trial anything outside of this would be considered malpractice. Ananthram Shetty, professor of minimally-invasive surgery at Canterbury Christ Church University, UK, said the guidelines are much-needed, welcome move in the right direction.
Prof. Shetty, who has been working with stem-cell technology for 27 years, and is often in India to demonstrate their use in research surgeries, said this would prevent anybody and everybody from claiming unproven benefits. Lots of people dont really understand what stem cells are. And those who have a terminal illness are willing to try anything. There are some people who use this to raise false hopes. And this is what the guidelines seek to stop, he said.
J.S. Rajkumar, chairman, Lifeline Hospital, however, said the guidelines could have been clearer about the use of adult stem cells over embryonic stem cells, he said. Now, the procedures involved and the time it would take could dissuade many, he said, while there is a real need for funds to be pumped in for research into this technology.
Another International Ear Care Day passed by on March 3.
It spelled out a clear message ear care can avoid hearing loss.
But the question is how many people know how to take care of their ears. What is interesting is the ear is a self-cleaning organ and does not require any kind of cleaning. But many clean their ears using safety pins, hair pins and even matchsticks.
While doctors advise against the use of such objects, they discourage the use of cotton buds too. Some heat coconut oil and pour into the ears. This could cause fungal infections. The ear drum is very thin and can be damaged, leading to loss of hearing, said M. Ramaniraj, professor of ENT, Government Stanley Medical College Hospital.

Guidelines on use of stem cell therapy
Transplanted human umbilical cord blood cells improved heart function in rat model of MI
By Dr. Matthew Watson
PUBLIC RELEASE DATE:
6-Mar-2014
Contact: Robert Miranda cogcomm@aol.com Cell Transplantation Center of Excellence for Aging and Brain Repair
Putnam Valley, NY. (Mar. 6, 2014) When human umbilical cord blood cells were transplanted into rats that had undergone a simulated myocardial infarction (MI), researchers investigating the long term effects of the transplantation found that left ventricular (LV) heart function in the treated rats was improved over those that did not get the stem cells. The animals were maintained without immunosuppressive therapy.
The study will be published in a future issue of Cell Transplantation but is currently freely available on-line as an unedited early e-pub at: http://www.ingentaconnect.com/content/cog/ct/pre-prints/content-ct0860Chen.
"Myocardial infarction induced by coronary artery disease is one of the major causes of heart attack," said study co-author Dr. Jianyi Zhang of the University of Minnesota Health Science Center. "Because of the loss of viable myocardium after an MI, the heart works under elevated wall stress, which results in progressive myocardial hypertrophy and left ventricular dilation that leads to heart failure. We investigated the long term effects of stem cell therapy using human non-hematopoietic umbilical cord blood stem cells (nh-UCBCs). These cells have previously exhibited neuro-restorative effects in a rodent model of ischemic brain injury in terms of improved LV function and myocardial fiber structure, the three-dimensional architecture of which make the heart an efficient pump."
According to the authors, stem cell therapy for myocardial repair has been investigated extensively for the last decade, with researchers using a variety of different animal models, delivery modes, cells types and doses, all with varying levels of LV functional response. They also note that the underlying mechanisms for improvement are "poorly understood," and that the overall regeneration of muscle cells is "low."
To investigate the heart's remodeling processes and to characterize alterations in the cardiac fiber architecture, the research team used diffusion tensor MRI (DTMRI), used previously to study myofiber structure in both humans and animals.
While most previous studies have been focused on the short term effects of UCBCs, their study on long term effects not only demonstrated evidence of significantly improved heart function in the treated rats, but also showed evidence of delay and prevention in terms of myocardial fiber structural remodeling, alterations that could have resulted in heart failure.
When compared to the age-matched but untreated rat hearts with MI, the regional myocardial function of nh-UCBC-treated hearts was significantly improved and the preserved myocardial fiber structure may have served as an "underlying mechanism for the observed function improvements."

3D printing helps create tailor-made wrap-around heart sensor array
By Dr. Matthew Watson
Researchers have used 3D-printed models of the heart to create a personalized wrap-around heart sensor array which can transmit highly detailed information on a patients cardiac health and may thus help to predict and prevent serious medical problems.
The buzz surrounding 3D printing sometimes gives the impression that the technology provides a miracle solution for making any manufactured product more cheaply. In fact the main advantage of the technology is to be able to produce prototypes cheaper and faster or to customize products and components. The medical sector may well be among the first to benefit from this latter approach by using the technique, formally known as additive layer manufacturing (ALM), to produce tailor-made surgical implants. At the moment, medical researchers are focusing on highly ambitious projects such as printing replacement organs from a persons own stem cells, but this procedure will take years of development before it can be widely used on patients. Recently researchers have used 3D printing to help create a rather more modest device which could be incorporated fairly quickly into treatment procedures. Every heart has its own unique size and shape, and medical procedures need to be adjusted accordingly in order to deliver fully personalised treatment. Now researchers Igor Efimov of WashingtonUniversity in St Louisand John Rogers at the University of Illinoishave demonstrated a new type of tailor-made cardiac sensor array which increases the quantity and improves the quality of the information gathered, and thus help prevent certain cardiac problems.
Efimov, a cardiac physiologist and bioengineer, and Rogers, a materials scientist, used optical images of rabbits hearts to demonstrate the concept of creating an ALM model of the heart in order to make the sensor array. In fact CT or MRI scans of each persons heart would be used to make devices for human patients. Having 3D-printed the model of the heart, they then built a stretchy electronic mesh structure a sort of envelope to wrap round the model. The stretchy material can then be peeled off the printed model and wrapped around the real heart in a perfect fit. This technique enables a far more precise approach than has hitherto been feasible and the research team were able to integrate an unprecedented number of components into the device, including embedded sensors, oxygenation detectors, thermometers and electrodes that can, if need be, deliver electric shocks to stimulate a flagging heart. Although the device has been developed specifically to treat ventricular deformation andcardiacarrhythmia, it could incorporate different types of sensors in order to improve treatment for a number of other heart conditions, inter alia enabling medicines to be delivered to the exact spot where they are needed.
Igor Efimov reveals that the next step is a device with multiple sensors, and not just more electrical sensors. Sensors that measure acidity, for instance, could provide an early warning of a blocked coronary artery. So far, the researchers have tested their technology on beating rabbit hearts outside the body. The next stage will be to demonstrate that this approach can work in live animals before it can be tested on people. Although devices made in this kind of custom-manufacturing process would probably be more expensive than mass-produced medical implants, using ALM to print the basic heart model will bring the cost down considerably and help to ensure that the technology becomes available to patients who need it. In any case, argues Stanford University materials scientist Zhenan Bao, for these kinds of life-or-death applications, the market is likely to bear the cost, given the rich information that the device will provide, enabling early treatment of potentially serious conditions. The idea of incorporating IT devices into organs is becoming more commonplace and there could be many medical applications, such as devices to assist bladder control or mitigate conditions of the nervous system. In a less life-and-death field, the technology could also be used for body digitisation with a view to producing tailor-made clothing.
