Fat stem cells may help treat kidney ailments

Posted: May 25, 2012 at 8:16 pm

Fat stem cells may help treat kidney ailments BS Reporter / Mumbai/ AhmedabadMarch 06, 2007 In a breakthrough in the stem cell research, scientist from Ahmedabad have developed a technique to encourage a new kind of stem cells called Mesenchymal stem cells generated from fat (adipose tissue) of donors, which can be used in treating kidney diseases. Mesenchymal stem cells generated from fat of donors hold great promise for the treatment of kidney diseases, claims H L Trivedi, director, Institute of Kidney Diseases and Research Center (IKDRC), Ahmedabad. We will soon patent the research, he added. The institute will soon convene a meeting of scientists working on the project and take a decision on securing the patent for the research. A team of scientists from the IKDRC, led by Trivedi, has clinically proved that when presented in the right physical context, certain growth factors encourage the survival and proliferation of fat mesenchymal stem cells grown outside the body. Trivedi says the research offers hope of cent per cent recovery for patients suffering from severe kidney diseases as the mesenchymal stem cells will nullify the rejection rate of the body, thus inducing the body to accept the newly transplanted kidney as part of its own body. Emphasising on the success of mesenchymal stem cells for kidney treatment, Trivedi further said mesenchymal stem cells were the best repair stem cells compared to other stem cells. The worlds first recipient of these kinds of stem cells is a kidney patient - Hetalben Mewada, a 30-year-old housewife from Palanpur in Gujarat, claims the scientist from IKDRC. Speaking about the financial aspect of the kidney treatment, Trivedi said, Mesenchymal stem cells using fat is simple and cheap. The latest invention would cut the cost of surgery drastically and make it affordable for the needy people. It will also reduce the chances of recurrence and complexity in the post surgery situation, he said. Mesenchymal stem cells are available in bone marrow and peripheral blood cells in smaller quantity, but the cells are not economically feasible. Mesenchymal stem cells can be easily derived from fat and is economically viable. Mesenchymal stem cells that are already in the fats are separated and grown through culturing technique in laboratory. IKDRCs scientists carried out a kidney transplant operation using Mesenchymal stem cells derived from fats along with adult hematopoietic stem cells infused into the transplanted kidney to create tolerance or acceptance by the patients. This eliminates the chance of rejection, and the patients would not need medication. Under this procedure, the mesenchymal stem cells act as a big brother to adult hematopoietic stem cells. Mesenchymal stem cells protect these hematopoietic stem cells and help their grafting into different organs by themselves getting grafted and making space for their younger siblings (adult hematopoietic stem cells) to live along with them in their vicinity.

New drug destroys human cancer stem cells without affecting healthy ones

Posted: May 25, 2012 at 8:16 pm

Washington, May 25 : A study led by an Indian origin scientist has discovered a drug that successfully kills cancer stem cells in the human while avoiding the toxic side-effects of conventional cancer treatments.

Unlike chemotherapy and radiation, the drug - thioridazine - appears to have no effect on normal stem cells, according to the scientists at McMaster University.

"The unusual aspect of our finding is the way this human-ready drug actually kills cancer stem cells; by changing them into cells that are non-cancerous," said Mick Bhatia, the principal investigator for the study and scientific director of McMaster's Stem Cell and Cancer Research Institute in the Michael G. DeGroote School of Medicine.

The finding holds the promise of a new strategy and discovery pipeline for the development of anticancer drugs in the treatment of various cancers. The research team has identified another dozen drugs that have good potential for the same response.

To test more than a dozen different compounds, McMaster researchers pioneered a fully automated robotic system to identify several drugs, including thioridazine.

Bhatia's team found thioridazine works through the dopamine receptor on the surface of the cancer cells in both leukemia and breast cancer patients.

This means it may be possible to use it as a biomarker that would allow early detection and treatment of breast cancer and early signs of leukemia progression, he said.

The research team's next step is to investigate the effectiveness of the drug in other types of cancer. In addition, the team will explore several drugs identified along with thioridazine.

The research has been published in the science journal CELL. (ANI)

5 scientists receive stem-cell research grants

Posted: May 25, 2012 at 8:13 pm

Five scientists from the University of California, San Diego and its School of Medicine have been awarded almost $12 million in new grants from the California Institute for Regenerative Medicine (CIRM) to conduct stem cell-based research into regenerating spinal cord injuries, repairing gene mutations that cause amyotrophic lateral sclerosis and finding new drugs to treat heart failure and Alzheimer's disease.

The awards mark the third round of funding in CIRM's Early Translational Awards program, which supports projects that are in the initial stages of identifying drugs or cell types that could become disease therapies. More than $69 million in awards were announced yesterday, including funding for first-ever collaboratively funded research projects with China and the federal government of Australia.

"With these new awards, the agency now has 52 projects in 33 diseases at varying stages of working toward clinical trials," said Jonathan Thomas, JD, PhD and CIRM governing board chair. "Californians should take pride in being at the center of this worldwide research leading toward new cures. These projects represent the best of California stem cell science and the best international experts who, together, will bring new therapies for patients."

The five new UC San Diego awards are:

CIRM was established in November 2004 with the passage of Proposition 71, the California Stem Cell Research and Cures Act. The statewide ballot measure provided $3 billion in funding for stem cell research at California universities and research institutions and called for the establishment of an entity to make grants and provide loans for stem cell research, research facilities, and other vital research opportunities.

The May 24 grants bring UC San Diego's total to more than $112 million in CIRM funding since the first awards in 2006.

"Californians should take pride in being at the center of this worldwide research leading toward new cures. These projects represent the best of California stem cell science and the best international experts who, together, will bring new therapies for patients."

The five new UC San Diego awards are:

With a $1.8 million award, Lawrence Goldstein, PhD, professor in the Department of Cellular and Molecular Medicine, Howard Hughes Medical Institute Investigator and director of the UC San Diego Stem Cell Program, and colleagues will continue their work developing new methods to find and test drug candidates for Alzheimer's disease (AD). Currently, there is no effective treatment for AD. The researchers screen novel candidates using purified human brain cells made from human reprogrammed stem cells. Already, they have discovered that these human brain cells exhibit a unique biochemical behavior that indicates early development of AD in a dish.

Mark H. Tuszynski, MD, PhD, professor of neurosciences and director of the Center for Neural Repair at UC San Diego, and colleagues seek to develop more potent stem cell-based treatments for spinal cord injuries. By combining grafts of neural stem cells with scaffolds placed at injury sites, the researchers have reported substantial progress in restoring functional improvement in impaired animal models. The new $4.6 million grant will fund work to identify the optimal human neural stem cells for preclinical development and, in an unprecedented step, test this treatment in appropriate preclinical models of spinal cord injury, providing the strongest validation for human translation.

Amyotrophic lateral sclerosis or ALS (Lou Gehrig's disease) is a progressive neurological condition that is currently incurable. Gene Yeo, PhD, assistant professor in the Department of Cellular and Molecular Medicine, and colleagues will use a $1.6 million grant to exploit recent discoveries that specific mutations in RNA-binding proteins cause neuronal dysfunction and death. They will use neurons generated from patient cells containing the mutations to identify the unique RNA "signature" of these doomed neurons and screen for drug-like compounds that bypass the mutations to correct the RNA signature to obtain healthy neurons.

Eric David Adler, MD, an associate clinical professor of medicine and cardiologist, studies heart failure, including the use of stem cells to treat it. His $1.7 million award will fund research into Danon disease, a type of inherited heart failure that frequently kills patients by their 20s. Adler and colleagues will turn stem cells created from skin cells of patients with Danon disease into heart cells, then screen hundreds of thousands of drug candidates for beneficial effects. The most promising drugs will subsequently be tested on mice with a genetic defect similar to Danon disease, with the ultimate goal of identifying a suitable candidate for human clinical trials. The research may have broader applications for other conditions with similar pathogenesis, such as cancer and Parkinson's disease.

Biostem U.S., Corporation Announces $5,000,000 Financing Agreement Through Private Placement of Stock

Posted: May 25, 2012 at 8:13 pm

CLEARWATER, FL--(Marketwire -05/24/12)- Biostem U.S., Corporation, (HAIR.PK) (HAIR.PK) (Biostem, the Company), a fully reporting public company in the stem cell regenerative medicine sciences sector, announces a $5,000,000 financing agreement through private placement of stock.

CEO, Dwight Brunoehler, announced today that the company has signed an agreement with a funder to issue 20,000,000 shares of the company's common stock in exchange for $5,000,000 in cash or 25 cents ($.25) per share. No other considerations will be granted to the funder in exchange for the cash payment.

In announcing the funding agreement, Mr. Brunoehler commented, "We consider the eagerness of the funder to acquire Biostem shares at a price above the current market to be a tribute to our proven proprietary technology to enhance hair re-growth using human stem cells. Although we anticipated funding the company through the sale of a convertible debenture, the funder insisted on being able to acquire stock at a set price now, rather than risk having to convert at higher prices later. Although Rule 144 sale restrictions usually cause private placements of stock to be executed at a discount to the market, Biostem feels that its current share price is not truly reflective of the value of its proprietary technology; as well as the fact that the technology is already being employed, and the overall size of the hair replacement marketplace. It was for this reason that the company and the funder were able to come to an agreement to price the private placement above the current share price."

UCI stem cell researcher to receive $4.8 million in state funding

Posted: May 25, 2012 at 8:13 pm

Public release date: 24-May-2012 [ | E-mail | Share ]

Contact: Tom Vasich tmvasich@uci.edu 949-824-6455 University of California - Irvine

Irvine, Calif., May 24, 2012 A UC Irvine immunologist will receive $4.8 million to create a new line of neural stem cells that can be used to treat multiple sclerosis.

The California Institute for Regenerative Medicine awarded the grant Thursday, May 24, to Thomas Lane of the Sue & Bill Gross Stem Cell Research Center at UCI to support early-stage translational research.

CIRM's governing board gave 21 such grants worth $69 million to 11 institutions statewide. The funded projects are considered critical to the institute's mission of translating basic stem cell discoveries into clinical cures. They are expected to either result in candidate drugs or cell therapies or make significant strides toward such treatments, which can then be developed for submission to the Food & Drug Administration for clinical trial.

Lane's grant brings total CIRM funding for UCI to $76.65 million.

"I am delighted that CIRM has chosen to support our efforts to advance a novel stem cell-based therapy for multiple sclerosis," said Peter Donovan, director of the Sue & Bill Gross Stem Cell Research Center.

MS is a disease of the central nervous system caused by inflammation and loss of myelin, a fatty tissue that insulates and protects nerve cells. Current treatments are often unable to stop the progression of neurologic disability most likely due to irreversible nerve destruction resulting from myelin deficiencies. The limited ability of the body to repair damaged nerve tissue highlights a critically important and unmet need for MS patients.

In addressing this issue, Lane who also directs UCI's Multiple Sclerosis Research Center will target a stem cell treatment that will not only halt ongoing myelin loss but also encourage the growth of new myelin that can mend damaged nerves.

"Our preliminary data are very promising and suggest that this goal is possible," said Lane, a Chancellor's Fellow and professor of molecular biology & biochemistry. "Research efforts will concentrate on refining techniques for production and rigorous quality control of transplantable cells generated from high-quality human pluripotent stem cell lines, leading to the development of the most therapeutically beneficial cell type for eventual use in patients with MS."

State awards stem cell grants to medical researchers

Posted: May 25, 2012 at 8:13 pm

SACRAMENTO California's stem cell agency today approved two grants to UC Davis Health System researchers for their innovative work in regenerative medicine.

Kyriacos A. Athanasiou, distinguished professor of orthopaedic surgery and professor and chair of biomedical engineering, and the Child Family Professor of Engineering at UC Davis, is investigating the use of skin-derived stem cells to heal cartilage injuries and debilitating conditions of the knee such as osteoarthritis.

W. Douglas Boyd, professor of surgery, plans to further refine a novel approach to treating cardiovascular injuries suffered during a heart attack by using stem cells and a tissue-like scaffold to repair cardiac damage.

The pair received individual grants totaling approximately $6.6 million from the California Institute for Regenerative Medicine's (CIRM) governing board.

Athanasiou's and Boyd's multi-year grants were among the proposals submitted to CIRM for its third round of Early Translational Awards, which are intended to enable clinical therapies to be developed more rapidly.

"Both of these scientists are conducting exciting research that could have far-reaching implications in health care," said Jan Nolta, director of the UC Davis Institute for Regenerative Cures and the university's stem cell program director. "Dr. Athanasiou is bioengineering new cartilage that could have the same physiological integrity as the cartilage a person is born with. Dr. Boyd is developing a treatment that uses a paper-thin patch embedded with stem cells to harness their regenerative powers to repair damaged heart muscle."

Boyd, who's a pioneering cardiothoracic surgeon, pointed out in his CIRM proposal that heart disease is the nation's number-one cause of death and disability. An estimated 16.3 million Americans over the age of 20 suffer from coronary heart disease, which in 2007 accounted for an estimated 1 in 6 deaths in the U.S. Boyd plans to use bone-marrow derived stem cells -- known as mesenchymal stem cells -- in combination with a bioengineered framework known as an extracellular matrix, to regenerate damaged heart tissue, block heart disease and restore cardiac function, something currently not possible except in cases of a complete and very invasive heart transplant.

An expert in biomedical engineering, Athanasiou is focusing on developing a cellular therapy using stem cells created from an individual's own skin -- known as autologous skin-derived stem cells -- which have shown great promise in animal models. He plans to use the new funding to conduct extensive toxicology and durability tests to determine the technique's long-term safety and efficacy. Such tests are among the many steps needed to advance toward human clinical trials.

Cartilage is the slippery tissue that covers the ends of bones in joints, allowing bones to glide over each other and absorbing the shock of movement. Cartilage defects from injuries and lifelong wear and tear can eventually degenerate into osteoarthritis. According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, osteoarthritis is the most common form of arthritis and affects an estimated 27 million Americans over the age of 25.

"For anyone suffering from osteoarthritis or other debilitating cartilage conditions, Dr. Athanasiou's goal of using stem cells to regenerate new tissue could have enormous quality-of-life and economic benefits," said Nolta, who is the recipient of a prior translational grant from CIRM to develop potential therapies for Huntington's disease . "Dr. Boyd's work is equally promising because he's using a bioengineered structure to encourage cardiac tissue repair, which could have important benefits in the treatment of heart disease."

Di’Anno Wants Former Iron Maiden Bandmate To Undergo Stem Cell Therapy

Posted: May 25, 2012 at 8:12 pm

05/24/2012 . (Classic Rock) Former Iron Maiden singer Paul Di'Anno wants his ex-bandmate Clive Burr to undergo stem cell therapy, despite the costs and risks associated with the procedure.

Burr, the drummer with Maiden from 1979 until 1982, has been in a wheelchair as a result of multiple sclerosis, which has been attacking his nervous system since before he was diagnosed in 2002.

MS reduces the ability of the brain and spinal cord to communicate with each other, resulting in a wide range of potentially severe symptoms. The cause is unknown and there is no cure; but in 2009 researchers made the first breakthrough in reversing symptoms through stem cell therapy.

Di'Anno tells Talking Metal Pirate Radio Burr's condition is "not very good at all." He had a lot to say, read it here.

Old drug could have new use as cancer stem cell killer

Posted: May 24, 2012 at 5:10 pm

Date: Thursday May. 24, 2012 12:48 PM ET

An old drug once used routinely as a treatment for schizophrenia appears to be able to successfully kill human cancer stem cells while leaving healthy cells intact, Canadian researchers have discovered.

The discovery is an important one since traditional chemotherapy and radiationoften fail toeradicate cancer stem cells, which are cells that can lurk in the body and cause certain kinds ofcancer to return.

But a team of scientists at McMaster University has discovered that the antipsychotic medication thioridazine can destroy cancer stem cells by changing them into cells that are non-cancerous. And unlike chemotherapy and radiation, thioridazine appears to have no effect on normal stem cells, which could mean side effects like hair loss.

The team at McMaster's Stem Cell and Cancer Research Institute made their finding while testing hundreds of compounds using an automated robotic stem cell screening system. Thioridazine was one of abouta dozen already-known compounds that the robotic team found had good potential as cancer treatments.

Mick Bhatia, the principal investigator for the study and scientific director of the Institute, says what makes this drug so exciting is that it has already been approved for use in patients.

"I think it is fascinating because the drug has already been used already -- albeit for another purpose; here it is being repurposed for cancer. The fact that all that workup has been done already allows us to move this into the clinic quickly," he says.

The research is published in the science journal, Cell.

The next step is to test thioridazine in clinical trials on cancer patients. The first study will focus on 30 patients with acute myeloid leukemia, or AML, whose disease has relapsed after chemotherapy.

The team wants to find out if the drug can put their cancer into remission, and prevent it from returning, says co- investigator Terry Sachlos.
