US Stem Cell Inc (OTCMKTS:USRM) Explodes Higher Ahead of RMAT Decision – The Oracle Dispatch

US Stem Cell Inc (OTCMKTS:USRM) is a penny player in the stem cell space that caught a massive jolt of bullish energy to start off this week. We didnt see any clear new catalyst emerge, but the move likely hooks into the companys near-term narrative, which is highly entangled with a decision of whether or not to approve the companys application to the FDA for Regenerative Medicine Advanced Therapy (RMAT) Designation for the MyoCell product as part of its MARVEL trial.

According to a press release last month, the trial had previously been placed on Inactive Status as patients were not actively being enrolled. A request was placed to the FDA to reactivate the protocol and consider the therapy for RMAT designation. We have recently heard from the FDA who has notified us that the protocol has been placed on Reactivation Status after reviewing details on the protocol and data collected on patients to date. The FDA has also notified us that they are still reviewing our submission for RMAT.

US Stem Cell Inc (OTCMKTS:USRM) bills itself as a company committed to the development of effective cell technologies to treat a variety of diseases and injuries. By harnessing the bodys own healing potential, we may be able to reverse damaged tissue to normal function.

U.S. Stem Cells discoveries include multiple cell therapies in various stages of development that repair damaged tissues throughout the body due to injury or disease so that patients may return to a normal lifestyle.

USRM is focused on regenerative medicine. While most stem cell companies use one particular cell type to treat a variety of diseases, U.S Stem Cell utilizes various cell types to treat different diseases. It is our belief that the unique qualities within the various cell types make them more advantageous to treat a particular disease.

According to company materials, US Stem Cell, Inc. (formerly Bioheart, Inc.) is an emerging enterprise in the regenerative medicine / cellular therapy industry. We are focused on the discovery, development and commercialization of cell based therapeutics that prevent, treat or cure disease by repairing and replacing damaged or aged tissue, cells and organs and restoring their normal function. We believe that regenerative medicine / cellular therapeutics will play a large role in positively changing the natural history of diseases ultimately, we contend, lessening patient burdens as well as reducing the associated economic impact disease imposes upon modern society.

Subscribe below and well keep you on top of whats happening before $USRM stock makes its next move.

As noted above, the stock shifted into bull mode to start this week. However, traders are scrambling to uncover the catalyst for the move.

We would say the most likely catalyst has to do with expectations surrounding its application for RMAT status with the FDA. That was apparently expected to hit as a decision sometime in May. Today marks the outset of the new month, and we may have either rumors or speculation fueling the idea that one must not wait any longer if one wants to catch the action into that catalyst the idea being, approval would seriously juice this stock higher.

Recent action has seen 33% piled on for shareholders of the company during the trailing week. This is emblematic of the stock. USRM has evidenced sudden upward volatility on many prior occasions. Whats more, the listing has benefitted from a jump in recent trading volume to the tune of 16% over what the stock has registered over the longer term.

According to the company, Thanks to the REGROW component of the Cures Act, the FDA will grant RAT designation for a regenerative medicine therapy that is intended to treat, modify, reverse, or cure a serious or life-threatening disease and demonstrates preliminary clinical evidence that the product has the potential to address unmet medical needs for a disease. We believe that our MyoCell product meets these requirements, as we have demonstrated clinical efficacy in both preclinical and clinical studies, including our most recent MARVEL trial publication.

Earning a current market cap value of $44.2M, USRM has a reported chunk ($271K) of cash on the books, which compares with about $3M in total current liabilities. USRM is pulling in trailing 12-month revenues of $3.1M. In addition, the company is seeing major top line growth, with y/y quarterly revenues growing at 66.6%. We will update the story again soon as developments transpire.

Presidential Symposium at the American Society of Gene and Cell … – Yahoo Finance

FREMONT, Calif., May 3, 2017 /PRNewswire/ --Asterias Biotherapeutics, Inc. (NYSE MKT: AST), a biotechnology company pioneering the field of regenerative medicine, today announced that data from its AST-OPC1 clinical program for severe cervical spinal cord injury will be presented during the Presidential Symposium at the American Society of Gene and Cell Therapy (ASGCT) 20th Annual Meeting, being held in Washington, D.C. during May 10-13, 2017.

"The ASGCT decision to include a presentation on AST-OPC1 in its Presidential Symposium signifies the ground-breaking nature of our program, and reflects the encouraging efficacy and safety data we have seen to date in patients with severe spinal cord injuries that have been treated with AST-OPC1," said Steve Cartt, President and Chief Executive Officer of Asterias. "Data will be presented from our SCiStar study demonstrating the potential of AST-OPC1 to help patients with complete paralysis regain increased arm, hand and finger function, and thus greater ability to live independently."

Jane S. Lebkowski, Ph.D., Asterias' President of R&D and Chief Scientific Officer, will be one of the presenters during the Presidential Symposium session scheduled on Friday, May 12, 2017 at 1:00pm Eastern Time. Dr. Lebkowski's presentation, titled "498 - Safety and Efficacy of Human Embryonic Stem Cell Derived Oligodendrocyte Progenitor Cells (AST-OPC1) in Patients with Subacute Cervical Spinal Cord Injury," is expected to begin at 2:15pm Eastern Time. The abstract for Dr. Lebkowski's presentation at the ASGCT meeting is available online at: http://www.abstractsonline.com/pp8/#!/4399/presentation/1996.

ASGCT is the primary professional membership organization for gene and cell therapy. The Society's members are scientists, physicians, patient advocates, and other professionals. Its members work in a wide range of settings including universities, hospitals, government agencies, foundations, biotechnology and pharmaceutical companies. Its mission is to advance knowledge, awareness, and education leading to the discovery and clinical application of gene and cell therapies to alleviate human disease.

About the SCiStar Trial

The SCiStar trial is an open-label, single-arm trial testing three sequential escalating doses of AST-OPC1 administered at up to 20 million AST-OPC1 cells in as many as 35 patients with sub-acute, C-5 to C-7, motor complete (AIS-A or AIS-B) cervical SCI. These individuals have essentially lost all movement below their injury site and experience severe paralysis of the upper and lower limbs. AIS-A patients have lost all motor and sensory function below their injury site, while AIS-B patients have lost all motor function but may retain some minimal sensory function below their injury site. AST-OPC1 is being administered 14 to 30 days post-injury. Patients will be followed by neurological exams and imaging procedures to assess the safety and activity of the product.

The study is being conducted at six centers in the U.S. and the company plans to increase this to up to 12 sites to accommodate the expanded patient enrollment. Clinical sites involved in the study include the Medical College of Wisconsin in Milwaukee, Shepherd Medical Center in Atlanta, University of Southern California (USC) jointly with Rancho Los Amigos National Rehabilitation Center in Los Angeles, Indiana University, Rush University Medical Center in Chicago and Santa Clara Valley Medical Center in San Jose jointly with Stanford University.

Asterias has received a Strategic Partnerships Award grant from the California Institute for Regenerative Medicine, which provides $14.3 million of non-dilutive funding for the Phase 1/2a clinical trial and other product development activities for AST-OPC1.

Additional information on the Phase 1/2a trial, including trial sites, can be found at http://www.clinicaltrials.gov, using Identifier NCT02302157, and at the SCiStar Study Website (www.SCiStar-study.com).

About AST-OPC1

AST-OPC1, an oligodendrocyte progenitor population derived from human embryonic stem cells, has been shown in animals and in vitro to have three potentially reparative functions that address the complex pathologies observed at the injury site of a spinal cord injury. These activities of AST-OPC1 include production of neurotrophic factors, stimulation of vascularization, and induction of remyelination of denuded axons, all of which are critical for survival, regrowth and conduction of nerve impulses through axons at the injury site. In preclinical animal testing, AST-OPC1 administration led to remyelination of axons, improved hindlimb and forelimb locomotor function, dramatic reductions in injury-related cavitation and significant preservation of myelinated axons traversing the injury site.

In a previous Phase 1 clinical trial, five patients with neurologically complete, thoracic spinal cord injury were administered two million AST-OPC1 cells at the spinal cord injury site 7-14 days post-injury. They also received low levels of immunosuppression for the next 60 days. Delivery of AST-OPC1 was successful in all five subjects with no serious adverse events associated with AST-OPC1. No evidence of rejection of AST-OPC1 was observed in detailed immune response monitoring of all patients. In four of the five patients, serial MRI scans indicated that reduced spinal cord cavitation may have occurred. Based on the results of this study, Asterias received clearance from FDA to progress testing of AST-OPC1 to patients with cervical spine injuries, which represents the first targeted population for registration trials.

Triggering Stem Cells for Accelerated Healing – Anti Aging News

Recent research, led by assistant professor of stem cell biology and regenerative medicine at the University of South Carolina Joseph T. Rodgers, has found a way to increase the bodys ability to heal after injury. The study was published in the scientific journal Cell Reports.

The research was funded by grants from the National Institutes of Health. Funding was also secured from the Donald E. and Delia B. Baxter Foundation, Glenn Foundation for Medical Research, and the Department of Veterans Affairs. The study was co-sponsored by the Department of Neurology and Neurological Sciences at Stanford. Clinical Research

In previous research, Rodgers proved that adult stem cells enter an alert state when the body sustains an injury. Alert stem cells have greater ability to heal and repair damaged tissues.

Rodgers theorized that blood from an injured person could produce a state of alert in another persons stem cells. Using lab mice, he and his team injected healthy mice with blood from their injured counterparts. The stem cells of the healthy mice were observed to adopt the state of alert.

The team was able to expose the chemical mechanism used to signal cells to enter an alert state as the enzyme Hepatocyte Growth Factor Activator (HGFA). HGFA is always present in the bloodstream but does not activate until the body experiences an injury. Once an injury occurs, the enzyme signals adult stem cells to enter the alert state.

Implications for Repair Response in the Injured Body

Once these findings were discovered, Rodgers team decided to investigate what would happen if an injury was sustained while the adult stem cells were already in a state of alert.

HGFA was injected into healthy mice. Several days later, the mice were given skin or muscle injuries. Test subjects were observed to heal faster, regrow missing fur, and return to running on exercise wheels sooner.

This research supports the idea that the presence of HGFA in the bloodstream prepares the body to respond more quickly and efficiently to injury. Similar to the way vaccines prepare the body to fight specific diseases, HGFA readies cells to respond to tissue damage.

Future Applications

In the future, people may be able to use HGFA before they engage in activities that could result in injury, like sports, surgery, or battle. HGFA could also be used in a therapeutic capacity for those with compromised healing abilities, like diabetes patients or senior citizens.

Forthcoming studies will explore how HGFA affects declines in the ability to heal, and how to use it to restore normal healing abilities.

Auto pioneer’s family turns tragedy into discovery with $5 million commitment to bipolar research – Medical Xpress

May 1, 2017 Stem cells derived from skin cells donated by people with and without bipolar disorder are helping researchers make discoveries about the condition at the most basic level. Credit: University of Michigan

Fifty years ago this spring, entrepreneur Heinz Prechter moved his company to Detroit, to answer car buyers' fast-growing demand for sunroofs. But even as his products brought light into more than a million vehicles, he fought darkness in his own life.

He struggled to keep his bipolar disorder hidden, until his suicide in July 2001 shocked the automotive industry.

Heinz's wife, Waltraud "Wally" Prechter, resolved to fight the stigma that led her husband to hide his mental illness, and to address the lack of scientific understanding about the condition and how best to treat it. She channeled her energy into helping the University of Michigan Depression Center do both, by donating and raising money for a U-M bipolar research fund in her husband's name.

Today, U-M named its entire bipolar disorder research program for Heinz Prechter, in honor of a new gift commitment of up to $5 million by the World Heritage Foundation - Prechter Family Fund.

But the gift comes with a challenge to others who care about bipolar disorder: The Prechter family will match every dollar given to U-M bipolar disease research up to $5 million. This will double the value of every donation, and the Prechter family gift will be available to researchers faster, if others step in to support the cause.

Once the challenge is met, the Prechter family's total giving to U-M bipolar research since Heinz Prechter's death will be well over $10 million. Philanthropic gifts, including individual, foundation and corporate gifts, are critical to the effort and account for more than half of the research funding in any given year. The Prechter family set up this gift as a match to encourage more philanthropic support of research into bipolar disorder.

"I think that if you canif you truly believe in somethingyou owe it to yourself to help, to give, and to make a difference. Because ultimately, that is all you leave behind," says Wally Prechter.

Says U-M president Mark Schlissel, M.D., Ph.D., "I deeply appreciate Wally Prechter's commitment to advancing bipolar disease research that will give hope to millions of people around the world. The Heinz C. Prechter Bipolar Research Program will enhance the University of Michigan's longstanding research initiatives and drive new medical discoveries to combat this devastating disorder."

Building new innovation and advancing bipolar science

"When we lost Heinz to his disease, it took Wally's bravery and generosity to help us create incredible good out of such a tragic loss," says John Greden, M.D., who was working with Heinz and Wally Prechter to create the U-M Depression Center at the time of Heinz's death. Greden is the Depression Center's director and a professor of psychiatry at Michigan Medicine, the U-M academic medical center.

"Without Wally Prechter's leadership over the past decade, we would not have been able to develop the world's first bipolar-specific stem cell lines, discover new genetic links, explore environmental factors or bring experts worldwide together as we have," says Melvin McInnis, M.D., who is the Thomas B. and Nancy Upjohn Woodworth Professor of Bipolar Disorder, professor of psychiatry, and director of the newly named Heinz C. Prechter Bipolar Research Program.

The Prechter family is committed to increasing scientific understanding and treatment options that will enable people with bipolar disorder to lead healthy and productive lives. The new gift will grow the endowment that provides for the continuation of the Prechter Longitudinal Study of Bipolar Disorder, which has been ongoing for 11 years.

The Longitudinal Study allows researchers to track symptoms, response to treatment and overall health over time like never before. Already, more than 1,200 dedicated individuals have partnered with the research team to track personal and medical information for this long-term study.

"Our participants are the real heroes," says Wally Prechter. "The goal of the Prechter Program is to identify effective solutions for people with bipolar disorder."

Volunteers can also donate samples of their blood, giving scientists the chance to study tiny differences in DNA that may play a role in how the disorder develops, why it runs in families, how it affects people over time and what makes people vary in their response to treatment.

The "bank" of DNA from hundreds of research participants over the last decade is called the Heinz C. Prechter Bipolar Genetics Repository, and it is the nation's largest privately funded bipolar genetics repository.

"We look forward to fueling new discoveries, and involving hundreds more people with bipolar and their families in the search for better treatments. The new funding, from the Prechters and others who believe in our work, will allow us to accelerate our pace of discovery," says McInnis.

The Heinz C. Prechter Bipolar Research Program will be the umbrella program over the Longitudinal Study of Bipolar Disorder and other bipolar research studies.

About bipolar disorder

Bipolar disorder is a devastating, chronic mental illness with recurring episodes of mania (highs) and depression (lows). The illness causes unusual and dramatic shifts in mood, energy and behavior. Presently, 30 percent of individuals with bipolar disorder attempt suicide during their lives, and 20 percent die by suicide.

Although the direct cause of bipolar disorder is unclear, it has long been understood that genetic, biochemical and environmental factors play a role. Bipolar disorder runs in families, tends to recur throughout the life span and is affected by genes and life experiences.

Stem Cells in Culture Have Tendency to Develop Cancer-Linked Mutations – Genetic Engineering & Biotechnology News

Stem cells that are grown in the lab are known to acquire mutations, but whether these mutations are particularly numerous or risky remains unclear. Mutations acquired in stem cell culture, it is feared, would complicate efforts to deploy stem cells in regenerative medicine. At the least, lab-grown stem cells may need to be screened for deleterious mutations, with special attention devoted to vulnerable portions of the genome or flaws that could lead to dire consequences, such as cancer.

To characterize the mutations that may arise among stem cells in vitro, scientists have been introducing gene-sequencing tests. For example, in a recent study, scientists based at Harvard have determined that human pluripotent stem cells are prone to develop mutations in the TP53 gene, which ordinarily helps suppress cancer. The mutated versions of the TP53 found by the Harvard team, however, tend to drive cancer development.

Details of this work appeared April 26 in the journal Nature, in an article entitled, Human Pluripotent Stem Cells Recurrently Acquire and Expand Dominant Negative P53 Mutations. This article describes how the Harvard team sequenced the protein-coding genes of 140 human embryonic stem cell (hES) cell lines26 of which were developed for therapeutic purposes using Good Manufacturing Practices, a quality control standard set by regulatory agencies in multiple countries. The remaining 114 human pluripotent stem cell lines were listed on the NIH registry of human pluripotent stem cells. This gene-sequencing exercise was followed by computational work that allowed the scientists to identify mutations present in a subset of cells in each cell line.

[We] identified five unrelated hES cell lines that carried six mutations in the TP53 gene that encodes the tumour suppressor P53, wrote the articles authors. The TP53 mutations we observed are dominant negative and are the mutations most commonly seen in human cancers. We found that the TP53 mutant allelic fraction increased with passage number under standard culture conditions, suggesting that the P53 mutations confer selective advantage.

The scientists also mined published RNA sequencing data from 117 human pluripotent stem cell lines, and observed another nine TP53 mutations, all resulting in coding changes in the DNA-binding domain of P53. In three lines, the authors of the Nature paper detailed, the allelic fraction exceeded 50%, suggesting additional selective advantage resulting from the loss of heterozygosity at the TP53 locus.

These findings suggest that cell lines should be screened for mutations at various stages of development as well as immediately before transplantation.

"Our results underscore the need for the field of regenerative medicine to proceed with care," said the study's co-corresponding author Kevin Eggan, Ph.D. "[They] indicate that an additional series of quality control checks should be implemented during the production of stem cells and their downstream use in developing therapies. Fortunately, these genetic checks can be readily performed with precise, sensitive, and increasingly inexpensive sequencing methods."

"Cells in the lab, like cells in the body, acquire mutations all the time," added Steve McCarroll, Ph.D., co-corresponding author. "Mutations in most genes have little impact on the larger tissue or cell line. But cells with a pro-growth mutation can outcompete other cells, become very numerous, and 'take over' a tissue. We found that this process of clonal selectionthe basis of cancer formation in the bodyis also routinely happening in laboratories."

Although the Harvard scientists expected to find some mutations in stem cell lines, they were surprised to find that about 5% of the stem cell lines they analyzed had acquired mutations the TP53 gene, which encodes the tumor suppressor protein P53.

Nicknamed the "guardian of the genome," P53 controls cell growth and cell death. People who inherit p53 mutations develop a rare disorder called Li-Fraumeni Syndrome, which confers a near 100% risk of developing cancer in a wide range of tissue types.

The specific mutations that the researchers observed are "dominant negative" mutations, meaning, when present on even one copy of P53, they are able to compromise the function of the normal protein, whose components are made from both gene copies. The exact same dominant negative mutations are among the most commonly observed mutations in human cancers.

The researchers performed a sophisticated set of DNA analyses to rule out the possibility that these mutations had been inherited rather than acquired as the cells grew in the lab. In subsequent experiments, the Harvard scientists found that P53 mutant cells outperformed and outcompeted nonmutant cells in the lab dish. In other words, a culture with a million healthy cells and one P53 mutant cell, said Dr. Eggan, could quickly become a culture of only mutant cells.

"The spectrum of tissues at risk for transformation when harboring a P53 mutation include many of those that we would like to target for repair with regenerative medicine using human pluripotent stem cells," noted Dr. Eggan. Those organs include the pancreas, brain, blood, bone, skin, liver, and lungs.

However, Drs. Eggan and McCarroll emphasized that now that this phenomenon has been found, inexpensive gene-sequencing tests will allow researchers to identify and remove from the production line cell cultures with concerning mutations that might prove dangerous after transplantation.

The researchers point out in their paper that screening approaches to identify these P53 mutations and others that confer cancer risk already exist and are used in cancer diagnostics. In fact, in an ongoing clinical trial that is transplanting cells derived from induced pluripotent stem cells, or iPSCs, gene sequencing is used to ensure the transplanted cell products are free of dangerous mutations.

Stem cell therapy relieves pain, restores joints – The Herald-News

The 360+ joints in the human body link bones and keep our bodies flexible. Until they become painful. Physical discomfort, where bones meet to form a joint, can be mild to intensely agonizing when the joints cartilage, ligaments, tendons, or muscles become inflamed and sore. Pain in one joint may be the result of an injury, or a condition such as tendonitis. Pain in multiple joints may indicate arthritis or gout.

Many joint pain problems in the knees, hips, and shoulders can be relieved with stem cell injection therapy, according to Dr. Frank Ostir, Director, Ostir Physical Medicine in Joliet. He explains that stem cells have anti-inflammatory properties plus growth factors. They relieve pain and rebuild damaged joints by regenerating into new tissue and cartilage. Stem cells can also heal torn ligaments.

They speed up the bodys own healing abilities. Theres no risk of tissue rejection, and no toxic substances or side effects. This regenerative treatment gives the best results in the shortest amount of time, Ostir says.

This phenomenal advancement in regenerative medicine makes it possible for patients to be pain-free and possibly avoid surgery through a minimally invasive procedure performed in the office. The actual procedure takes about 15 minutes. We used guided imaging from fluoroscopy and ultrasound technology to inject the stem cells to the exact site of affliction. The stem cells are mixed with a local anesthetic and injected through a small needle, to minimize any discomfort.

Ostir continues, The patient usually rests on the day of the injection, and resumes regular activity afterwards. About 80 percent of healing occurs in the first two months of treatment, due to the rate of stem cells replicating. Its our hope that this truly amazing therapy will eliminate the need for drugs and surgery.
