What Is Cardiac Cell Therapy?

In its simplest form, cardiac cell therapy is simply the use of stem cells to regenerate new heart tissue. Stem cells were originally used to grow your heart before you were born. Stem cells capable of growing new heart tissue reside in all of us. Through the use of trial-tested technologies, your own stem cells can be used to grow and repair your cardiac tissue.

The most difficult aspect of this therapy was developing a way to isolate your stem cells and put them to use to grow new heart tissue. And thanks to years of research, this process has been developed and tested in clinical trials with favorable results.

What Is The Procedure?

There is a wide variety of methods of placing stem cells in the body or near the organ they are intended to help. One procedure tested under trial is through the use of catheters (a specialized tube) and is being implemented in a new state-of-the-art clinic by a U.S. licensed veteran cardiologist. This process requires only a local anesthetic and minimal recovery time (hours vs days). And your own cardiologist is consulted closely to make sure you are a good candidate for the procedure and to monitor your improvements when you return home.

NEW YORK, July 7, 2014 /PRNewswire/ --Advanced Cell Technology, Inc. (OTCQB: ACTC) is a biotechnology company focused on developing and commercializing human pluripotent stem cell technology in the field of regenerative medicine. The company is currently conducting clinical trials for treating dry age-related macular degeneration (AMD) and Stargardt's macular degeneration (SMD), as well as several clinical and preclinical programs for other ocular therapies. Outside of ophthalmology, ACTC also has a preclinical development pipeline focused on autoimmune diseases, inflammatory diseases and wound healing. The company's intellectual property portfolio includes pluripotent human embryonic stem cells (hESCs), induced pluripotent stem cells (iPSCs), and other cell therapy research programs.

As the worldwide population has continued to age, so too has the need for regenerative medicine. In fact, by 2050, the number of people in the world over the age of 65 is expected to rise to 1.5 billion nearly triple the amount today. Unsurprisingly, as this demographic shift occurs over the next 35 years, health care expenditures are projected to increase rapidly as well. For example, in the US, the share of GDP devoted to healthcare is estimated to reach 34% by 2040 from about 18% just a few years ago. Considering the majority of treatments for chronic and/or life-threatening diseases that are available today only treat symptoms rather than offer a cure for the underlying cause, regenerative medicine such as the stem cell therapies being developed by ACTC are aimed at addressing this unmet and growing need.

Macular degeneration (i.e. age-related macular degeneration, or AMD) is a medical condition that results in a loss of vision in the center of the visual field (the macula) because of damage to the retina. This indication is the leading cause of blindness and visual impairment in adults over fifty years of age. Currently, it is estimated that there are approximately 30 million people worldwide who suffer from AMD ranging from early-stage to late-stage (i.e. legal blindness), with an estimated market size of around $30 billion. Further, in an article in the journal, Lancet projected that the number of people globally with AMD will be 196 million in 2020, growing to 288 million by 2040.

Council of Scientific and Industrial Research (CSIR) Centre for Cellular and Molecular Biology (CCMB) Director, Dr Ch. Mohan Rao today claimed that the heart disease can be treated without surgeries in future.

Addressing after inaugurating the 19th Annual conference of the Cardiological Society of India (CSI-AP Chapter) here, Dr Rao said that in the recent research in molecular biology found that 'heart' too have 'stem cells' which will help to automatically build the damaged part of any organ.

He said that further research also going with collaboration of other foreign institutions on how to bring the 'stem cells' out and repair.

Once the solution is found, the cardiac diseases can be healed with surgery, Dr Rao said.

''This development will make the stem cell based therapy replace the chemical based therapy in Cardiology,'' he added.

Irregular eating habits and busy lifestyle are among the major causes of the cordial illness, he said and advised to the youth to follow healthy lifestyle to avoid heart related problems.

While talking about the latest research, he said, ''To reduce the deaths due to cardiac illness the CCMB is working along with the scientists from Japan, the US and Italy to develop the an easier way to treatment.''

Dr Rao also given a clarion call to Cardiology experts to come forward for joint research on cardiac problems.

Encouraging the research in Cardiology, Dr Rao also invited the young medicos to visit the CCMB campus and work with the institute.

Discussing various kinds of heart diseases, he said, ''Dilated Cardiomyopathy is one of the most common heart disease among the children.''

Cardiac diseases to be treated without surgeries soon as stem cells found

Federal funding blocked mainly over opposition to use of blastocysts

PORTSMOUTH Dr. Amy Sievers, an oncologist at Portsmouth Regional Hospital, does stem cell transplants with great success for her patients and is a firm advocate for stem cell research.

Sievers is allowed to do stem cell blood transplants because she does not use the source of controversy, embryonic stem cells. Instead, she can use stem cells from bone marrow, where blood is made. The cells can become new blood for transfusion into patients with blood-related cancers like leukemia.

"When we get past the chemo and radiation, the hope is we can replace blood and give the patient healthy blood and a chance to build a good immune system," Sievers said.

Parents saving cord blood when they give birth is an option, but Dr. Alexandra Bonesho of Core Physicians in Epping said it is very costly for the patient, is not covered by insurance and is not something pediatricians recommend widely unless there is a reason.

"It's not something we use as a practical course of events," Bonesho said. "Cord blood banking is very expensive, less so if the blood stem cells are donated to the National Cord Blood Bank. In most cases, the chance that you will need it for your own child is unlikely, unless there is already a known condition in the family."

For example, if there is a history of leukemia in another child, it may be worthwhile. Bonesho said in a case like that, having the baby's own blood stem cells can be the perfect answer.

"However, chances are good that if there is a sibling, they may also be a good match if a bone marrow transplant is needed," Bonesho said. "However, transplants are not the normal course of treatment in children with leukemia."

That being said, the cord blood could eventually be used for research in the future to find a cure for diseases like sickle cell anemia, Bonesho said.

Federal funding for much stem cell research is blocked mainly over the opposition to using embryonic stem cells. The cells come from blastocysts (fertilized eggs) from an in-vitro facility. The blastocysts are excess and are usually donated by people who have already been successfully treated for fertility problems.

The promise and hazards of stem cell research

A study which had claimed to have come up with a new fast, easy, inexpensive and uncontroversial method of produce stem cells has now been retracted.

According to CNN, scientists had taken a skin cell and coaxed it into acting like an embryo, producing embryonic-like stem cells that could theoretically be turned into any cell in the body. What was described as a 'breakthrough' is how these cells were coaxed, by placing them in an acidic bath.

But the researchers, who had announced the results in January 2014, have now stated in their retraction that their papers had "several critical errors" in their study data.

An investigation into the studies was started by the Riken Center for Developmental Biology in Japan in February 2014, and the institution said its investigators had "categorized some of the errors as misconduct."

In fact, one of the co-authors of the study had also called for a retraction in March, because he questioned some of the data that were used in the experiments, which led to the creation of so-called STAP cells (or stimulus-triggered acquisition of pluripotency cells).

In an editorial accompanying the retraction, it was written that the errors were found in the figures, parts of the methods descriptions were found to be plagiarized, and early attempts to replicate the work failed.

The investigation found that data supposedly representing different cells and different embryos in the study were actually describing the same cells and the same embryos.

The study was published in the journal Nature, which is now accompanied by the retraction of all co-authors.

Fat removed from a heart attack patient during cardiac surgery could be re-injected into their chest to lower the risk of repeat problems, research suggests.

Scientists think that stem cells in fatty tissue could be extracted and inserted directly into the heart, reducing the chance of future attacks.

The stem cells - blank cells capable of acting as a repair kit for the body by replacing worn-out tissue - can improve the functioning of the heart and strengthen crucial arteries and veins, the researchers found.

Usually most of the fat that is found during open heart surgery is removed and then discarded.

Scientists believe fat removed from a heart attack patient during cardiac surgery could be re-injected into their chest to lower the risk of repeat problems. Stock image

But the new study suggests that the fat could be retained and the useful stem cells isolated and injected back into the heart - all while the patient is still on the operating table.

Canadian cardiologist Dr Ganghong Tian, who will present his findings at a European Society of Cardiology conference in Barcelona tomorrow (Sunday), said: During cardiac surgery fat tissue may need to be removed from patients to expose the heart.

We were intrigued to find out whether this mediastinal fat, which would otherwise be discarded, contained stem cells that could be injected back into the heart before closing the chest.

Fat cells removed from heart attack patients could be re-injected into their chest to help repair the organ ...

It sounds like something straight out of science fiction: stem cells from donated placentas are being injected into patients with hard-to-heal injuries. The results have been phenomenal, all by taking advantage of something that would be discarded as medical waste.

The stem cells inside a tiny vial will morph into something totally new once injected into the body. Dr. Brett Cascio is the Medical Director of Sports Medicine at Lake Charles Memorial Hospital and he is using this cutting edge technology in some of his toughest cases. We've know the special nature of stem cells for years, decades, he said, but harvesting them and getting them to do what we want them to do is the difficult part.

Dr. Cascio has treated all sorts of injuries - some that just have a tough time healing. For some reason along the way, their healing either stopped or went haywire and they didn't heal correctly, he said, and they need help on the cellular level to heal their problem.

That is where stem cells come in: not from a live human being, but from a donated placenta. The cells are tested, prepared and frozen until needed. One placenta can help hundreds of patients. You don't reject these cells, said Dr. Cascio, your body recognizes them as a potential healing factor and helps it to heal itself.

That healing is something Chad Theriot was desperate to find after rupturing the longest ligament in his foot while playing basketball. I heard a loud pop, he said, and then instant pain. I knew immediately that something was wrong.

Months passed with Theriot on crutches, in a boot, in pain and unable to be the family man he wanted to be. My wife was having to pick up slack everywhere, he said, at home, at work, with the baby.. I wasn't able to help much.

A second opinion brought Theriot to Dr. Cascio. The plan was to inject stem cells into the bottom of Theriot's foot , having them grow into good, healthy tissue in the place of what was damaged. So if you put them in connective tissue or skin, they can grow into skin-type cells or in muscle, they can grow into muscle-type cells, said Dr. Cascio.

Patients are given twilight anesthesia and the injections are given under X-ray guidance. The actual injection only takes one minute. Two weeks later I was taking unassisted steps and my pain level on a scale from one to ten went from an eight to a two, said Theriot.

That was the first time Theriot walked without help in four months. That was a big day for me, he said, that was a big day for us.

This stem cell technology is still in its early stages, but Dr. Cascio says the future is exciting. These are not magical cells, it's not like pixie dust, but they help the body heal itself and you can get some really amazing results, he said.

According to a new study appearing in the July 3 edition of the journal Cell Stem Cell, researchers from the Johns Hopkins University School of Medicine have uncovered a new genetic variant that could result in certain people having a predisposition to schizophrenia.

While there are many genetic variants that could increase the risk of developing a psychiatric disorder, they are insufficient to cause these diseases, the researchers explained. Now, however, the Johns Hopkins researchers have described a new strategy that could reveal how these so-called subthreshold genetic risks could impact the development of a persons nervous system by interacting with other risk factors.

This is an important step toward understanding what physically happens in the developing brain that puts people at risk of schizophrenia, senior author Dr. Guo-li Ming explained in a statement Thursday. Dr. Ming is a professor of neurology and neuroscience in the Johns Hopkins University School of Medicines Institute for Cell Engineering who worked on the study along with her husband, Dr. Hongjun Song.

In their study, Dr. Ming, Dr. Song and their colleagues explained that they used a multifaceted approach to find out why copy number variants in an area of the genome labeled 15q11.2 are prominent risk factors not just for schizophrenia, but for autism as well. Deletion of this part of a genome is associated with an increased risk of schizophrenia, but possessing extra copies results in an elevated risk of autism.

Their research focused on using a method which allows a patients skin cell to be reprogrammed into induced pluripotent stem cells (iPSCs), which can in turn be coaxed into creating any other type of cell. Using this technology, the study authors obtained stem cells from people with schizophrenia who were missing part of 15q11.2 on one of their chromosomes, ultimately coaxing them into neural progenitor cells, which are found in the developing brain.

By observing the process, the researchers found deficiencies during nerve development that could be linked to the gene CYFIP1, which maintains the structure of a nerve cell. By blocking the expression of this gene in developing mouse embryos, they found defects in the formation of the brains cerebral cortex, which plays a key role in consciousness.

The next step was to determine how this gene could interact with other factors, and they discovered that mutations in a pair of genes within a particular cellular pathway linked to CYFIP1 resulted in a significant increase in schizophrenia risk. According to the study authors, their research supports the belief that multiple factors in a single pathway could interact with one another to impact a patients potential risk for psychiatric disorders.

The reason, the team found, is that CYFIP1 plays a role in building the skeleton that gives shape to each cell, and its loss affects spots called adherens junctions where the skeletons of two neighboring cells connect, the university explained. A lack of CYFIP1 protein also caused some of the mice neurons to wind up in the brains wrong layer.

CHICAGO Bone marrow transplants can reverse severe sickle cell disease in adults, a small study by government scientists found, echoing results seen with a similar technique used in children.

The researchers and others say the findings show age need not be a barrier and that the technique may change practice for some adult patients when standard treatment fails. The transplant worked in 26 of 30 adults, and 15 of them were even able to stop taking drugs that prevent rejection one year later.

We're very pleased,'' said Dr. John Tisdale, the study's senior author and a senior investigator at the National Institutes of Health. This is what we hoped for.''

The treatment is a modified version of bone marrow transplants that have worked in kids. Donors are a brother or sister whose stem cell-rich bone marrow is a good match for the patient.

Tisdale said doctors have avoided trying standard transplants in adults with severe sickle cell disease because the treatment is so toxic. Children can often tolerate it because the disease typically hasn't taken as big a toll on their bodies, he said.

The disease is debilitating and often life-shortening; patients die on average in their 40s, Tisdale said. That's one reason why the researchers decided to try the transplants in adults, with hopes that the technique could extend their lives.

The treatment involves using chemotherapy and radiation to destroy bone marrow before replacing it with healthy donor marrow cells. In children, bone marrow is completely wiped out. In the adult study, the researchers only partially destroyed the bone marrow, requiring less donor marrow. That marrow's healthy blood cells outlast sickle cells and eventually replace them.

Sickle cell disease is a genetic condition that damages oxygen-carrying hemoglobin in red blood cells, causing them to form abnormal, sickle shapes that can block blood flow through the veins. It can cause anemia, pain and organ damage. The disease affects about 100,000 Americans, mostly blacks, and millions worldwide.

Results from the adult study, involving patients aged 29 on average, were published Tuesday in the Journal of the American Medical Association. The usual treatment hadn't worked, a drug called hydroxyurea, and they had transplants at an NIH research hospital in Bethesda, Maryland.

The treatment failed to reverse sickle cell in four of the 30 patients and one died of a disease-related complication. Another patient died suddenly a few weeks ago an elderly man whose transplant four years ago had been a success. Tisdale said that man had lived longer than the normal lifespan for sickle cell patients but that his death was unexpected and an autopsy was to be performed.

Following months of controversy, editors at the scientific journal Nature have retracted two high-profile studies that purported to demonstrate a quick and simple way of making flexible stem cells without destroying embryos or tinkering with DNA.

Several critical errors have been found in our Article and Letter, Nature wrote in a retraction statement issued Wednesday. We apologize for the mistakes.

------------

FOR THE RECORD

July 3, 7:53 a.m.: An article in the July 3 A section about two controversial stem cell studies that were retracted had stated that the decision was made by editors at the journal Nature. The retraction decision was made by the authors of the studies. Additionally, the comments in the retraction statement should have been attributed to the authors of the studies, not to the journal editors.

------------

The two reports described a new way of reprogramming blood cells so that they would revert to a developmentally primitive state and be capable of growing into any type of cell. Researchers from Japan and the United States said they accomplished this feat by soaking the cells in an acid bath for 30 minutes and then spinning them in a centrifuge for 5 minutes.

The resulting stem cells dubbed stimulus triggered acquisition of pluripotency, or STAP had the hallmarks of embryonic stem cells. When the researchers injected them into developing mice, the STAP stem cells grew into heart, bone and brain cells, among others, the research team reported in January.

Scientists in the field of regenerative medicine were giddy at the prospect of using the cells to grow new insulin-producing cells for people with Type 1 diabetes or central nervous system cells for people with spinal cord injuries, to name a few examples. Since these replacement tissues would be generated from a patients own cells, researchers believed they would not prompt the immune system to attack, eliminating the need for patients to take immune-suppressing drugs.

But it didnt take long for some researchers to suspect that STAP stem cells were too good to be true. Critiques posted online gained more currency when labs began reporting that they werent able to replicate the experiments. Then one of the senior researchers who worked on both of the studies called for the papers to be withdrawn until the results could be independently verified.

TAMPA

Twice a week, Gabriela Camargo and her husband, Romulo, get up before dawn to get him dressed, settled in his wheelchair and ready for the two-hour trip to Longwood, near Orlando, for the kind of intense, long-term physical therapy they hope will one day get him walking again.

After Romulo undergoes three hours of guided workouts on advanced exercise machines at Project Walk a therapy center unlike any in the Tampa Bay area, they say they fight the traffic back.

"I-4 is crazy!'' says Gabriela, adding that the couple usually arrives back home in New Tampa about 3:30 p.m.

After about a year of the routine, Gaby, as she's called, decided that she and "Romy'' should open a nonprofit intensive therapy center in Tampa.

"I thought it was a crazy idea,'' said Romy, an Army Special Forces officer who was shot in the neck and paralyzed from the shoulders down during an ambush in Afghanistan in 2008.

But the more he thought about it, the more he liked the plan.

They seem to be on their way, having collected about $216,000 in corporate and individual donations toward the $750,000 they figure they'll need for two years of operating expenses. They hope to open the StayInStep spinal cord injury therapy center in north Tampa in the fall.

Romy, a chief warrant officer 3, remains on active duty until his retirement next spring after 20 years in the service.

In 2011, Dr. Carlos Lima of Portugal, a pioneer in the use of stem cell surgery to stimulate nerve regeneration in spinal cord injury patients, operated on Romy, taking stem cells from tissue inside Romy's nose and transferring them to site of the injury.

July 4th Marks 75th Anniversary of Lou Gehrigs Farewell Speech

ROCHESTER, Minn. Seventy-five years ago, on July 4th 1939, baseball legend Lou Gehrig delivered the famous speech bidding farewell to the ballpark and his fans. Two weeks before Gehrig had been diagnosed with amyotrophic lateral sclerosis (ALS)at Mayo Clinicin Rochester, Minnesota. Accompanied by his wife, Eleanor, Lou left Mayo Clinic with the devastating diagnosis on June 20th 1939, a day after his 36th birthday. He died in June two years later, not quite 38 years old, of the rare neurological disease that would come to bear his name.

MULTIMEDIA ALERT: Journalists, the video package and addition b-roll are available in the downloads. To read the video script click here.

ALS is a type of progressive motor neuron disease that typically strikes at middle to later life and causes nerve cells in spinal cord, brain stem and brain to gradually break down and die. These nerve cells are responsible for muscle function so eventually, ALS can affect the ability to control the muscles needed to move, speak, eat and breathe.

While ALS still evades cure and effective treatment, researchers at Mayo Clinic are conducting Phase I clinical trial in the hope that they can guide newly grown stem cells to become protective of neuromuscular function.

We use fat-derived mesenchymal stem cells from the patient's own body. These cells are modified in the laboratory and delivered through a spinal tap into the fluid around the patient's nervous system to promote neuron survival, explains neurologist Anthony Windebank, M.D, deputy director for discovery in the Center for Regenerative Medicine at Mayo Clinic in Rochester. We hope that the growth factors that they are producing will help protect and promote the survival of nerve cells and therefore slow down or arrest the progression of ALS. If we can halt an ALS patient's loss of cells at 20 to 30 percent, that persons function would be well-preserved," says Dr. Windebank.

In the current phase of the FDA-controlled trial, Dr. Windebank and his team are studying the safety and efficacy of the treatment. If injecting ALS patients with stem cells grown from samples of their own fat tissue is found to be safe, the research would move to a Phase II, randomized, double blind, placebo-controlled trial to allow further study of safety and efficacy on a greater number of patients.

The FDA just approved another clinical trial in which Mayo Clinic will take part. The BrainStorm Phase II trial will look into whether stem cells can be used to actually replace the neurons that have been destroyed by ALS.

July 4th Marks 75th Anniversary of Lou Gehrigs Farewell Speech

A new study shows that adipose-derived human stem cells, which can become vital tissues such as bone, may be highly resistant to the common chemotherapy drug methotrexate (MTX). The preliminary finding from lab testing may prove significant because MTX causes bone tissue damage in many patients.

MTX is used to treat cancers including acute lymphoblastic leukemia, the most common form of childhood cancer. A major side effect of the therapy, however, is a loss of bone mineral density. Other bone building stem cells, such as bone marrow derived stem cells, have not withstood MTX doses well.

"Kids undergo chemotherapy at such an important time when they should be growing, but instead they are introduced to this very harsh environment where bone cells are damaged with these drugs," said Olivia Beane, a Brown University graduate student in the Center for Biomedical Engineering and lead author of the study. "That leads to major long-term side effects including osteoporosis and bone defects. If we found a stem cell that was resistant to the chemotherapeutic agent and could promote bone growth by becoming bone itself, then maybe they wouldn't have these issues."

Stem cell survivors

Originally Beane was doing much more basic research. She was looking for chemicals that could help purify adipose-derived stem cells (ASCs) from mixed cell cultures to encourage their proliferation. Among other things, she she tried chemotherapy drugs, figuring that maybe the ASCs would withstand a drug that other cells could not. The idea that this could help cancer patients did not come until later.

In the study published online in the journal Experimental Cell Research, Beane exposed pure human ASC cultures, "stromal vascular fraction" (SVF) tissue samples (which include several cell types including ASCs), and cultures of human fibroblast cells, to medically relevant concentrations of chemotherapy drugs for 24 hours. Then she measured how those cell populations fared over the next 10 days. She also measured the ability of MTX-exposed ASCs, both alone and in SVF, to proliferate and turn into other tissues.

Beane worked with co-authors fellow center member Eric Darling, the Manning Assistant Professor in the Department of Molecular Pharmacology, Physiology and Biotechnology, and research assistant Vera Fonseca.

They observed that three chemotherapy drugs -- cytarabine, etoposide, and vincristine -- decimated all three groups of cells, but in contrast to the fibroblast controls, the ASCs withstood a variety of doses of MTX exceptionally well (they resisted vincristine somewhat, too). MTX had little or no effect on ASC viability, cell division, senescence, or their ability to become bone, fat, or cartilage tissue when induced to do so.

The SVF tissue samples also withstood MTX doses well. That turns out to be significant, Darling said, because that's the kind of tissue that would actually be clinically useful if an ASC-based therapy were ever developed for cancer patients. Hypothetically, fresh SVF could be harvested from the fat of a donor, as it was for the study, and injected into bone tissue, delivering ASCs to the site.

To understand why the ASCs resist MTX, the researchers conducted further tests. MTX shuts down DNA biosynthesis by binding the protein dihydrofolate reductase so that it is unavailable to assist in that essential task. The testing showed that ASCs ramped up dihydrofolate reductase levels upon exposure to the drug, meaning they produced enough to overcome a clinically relevant dose of MTX.
