ScienceDaily (Feb. 15, 2012) — A UCSF stem cell study conducted in mice suggests a novel strategy for treating damaged cardiac tissue in patients following a heart attack. The approach potentially could improve cardiac function, minimize scar size, lead to the development of new blood vessels -- and avoid the risk of tissue rejection. In the investigation, reported online in the journal PLoS ONE, the researchers isolated and characterized a novel type of cardiac stem cell from the heart tissue of middle-aged mice following a heart attack. Then, in one experiment, they placed the cells in the culture dish and showed they had the ability to differentiate into cardiomyocytes, or "beating heart cells," as well as endothelial cells and smooth muscle cells, all of which make up the heart. In another, they made copies, or "clones," of the cells and engrafted them in the tissue of other mice of the same genetic background who also had experienced heart attacks. The cells induced angiogenesis, or blood vessel growth, or differentiated, or specialized, into endothelial and smooth muscle cells, improving cardiac function. "These findings are very exciting," said first author Jianqin Ye, PhD, MD, senior scientist at UCSF's Translational Cardiac Stem Cell … Continue reading →

NEW YORK, NY--(Marketwire -02/15/12)- Stem cell stocks have performed well of late, outperforming the S&P 500 by a large margin over the last three months. Since mid-November, TickerSpy's Stem Cell Stocks index (RXSTM) has returned more than 20 percent, as favorable news from some of stem cell industry heavyweights has boosted investor optimism in the sector.

The company develops, manufactures, and sells medical products and devices to enable the practice of regenerative medicine. The Company's technology is the Celuion family of products, which processes patients' adipose-derived stem and regenerative cells (ADRCs) at the point of care. In late January, Cytori received an Investigational Device Exemption (IDE) approval from the U.S. FDA to begin the "ATHENA" trial. ATHENA will investigate the use of the Celution System to treat a form of coronary heart disease, chronic myocardial ischemia (CMI).

A new study at Johns Hopkins University has shown that stem cells from patients' own cardiac tissue can be used to heal scarred tissue after a heart attack. This is certainly exciting news considering heart failure is still the No. 1 cause of death in men and women. The study included 25 heart attack victims, 17 of whom got the stem cell treatment. Those patients saw a 50% reduction in cardiac scar tissue after one year, while the eight control patients saw no improvement. The procedure involves removing a tiny portion of heart tissue through a needle, cultivating the stem cells from that tissue, and reinserting them in a second minimally invasive procedure, according to Bloomberg. "If we can regenerate the whole heart, then the patient would be completely normal," said Eduardo Marban, director of Cedars-Sinai Heart Institute who was the study's lead author. "We haven't fulfilled that yet, but we've gotten rid of half of the injury, and that's a good start."

Editor's Choice Main Category: Stem Cell Research Article Date: 15 Feb 2012 - 8:00 PST email to a friend   printer friendly   opinions   Current Article Ratings: Patient / Public: 5 (3 votes) Healthcare Prof: According to a study published in the February issue of the STEM CELL Translational Medicine Journal , a world-first technique for generating adult stem cells (mesenchymal stem cells [MSCs]) has been developed by researchers at the University of Queensland. This new method can be used to repair bone and possibly other organs, and will considerably affect individuals suffering from a variety of serious diseases. Professor Nicholas Fisk, who leads the collaborative study between the UQ Clinical Research Center (UQCCR) and the UQ's Australian Institute for Bioengineering and Nanotechnology (AIBN), explained: "We used a small molecule to induce embryonic stem cells over a 10 day period, which is much faster than other studies reported in the literature. The technique also worked on their less contentious counterparts, induced pluripotent stem cells. To make the pluripotent mature stem cells useful in the clinic, they have to be told what type of cell they need to become (pre-differentiated), before being administered to an injured organ, or otherwise they … Continue reading →

MARLBOROUGH, Mass.--(BUSINESS WIRE)-- Advanced Cell Technology, Inc. (“ACT”; OTCBB: ACTC), a leader in the field of regenerative medicine, announced today that the Wills Eye Institute in Philadelphia has received institutional review board (IRB) approval as a site for the company’s Phase I/II clinical trial for Stargardt’s Macular Dystrophy (SMD), a form of juvenile macular degeneration, using human embryonic stem cell (hESC)-derived retinal pigment epithelial (RPE) cells. Earlier this year, the Company also announced that the IRB at Wills Eye Institute had approved the participation of the institution as a site for ACT’s clinical trial for dry age-related macular degeneration (dry AMD). “We thank Wills Eye Institute once more for providing their IRB and their invaluable contribution to our macular degeneration studies,” said Gary Rabin, ACT’s chairman and CEO. “We are very happy that we can now report that Wills Eye Institute has been approved as a clinical trial site for both our SMD and dry AMD clinical trials. Ranked as one of the best ophthalmology hospitals in the country by U.S. News & World Report, the Wills Eye Institute is a truly world-class institution.
