Scientists watch stem cells at work regenerating tissue

Scientists have for the first time watched and manipulated stem cells as they regenerate tissue in an uninjured mammal, Yale researchers report July 1 online in the journal Nature.

Using a sophisticated imaging technique, the researchers also demonstrated that mice lacking a certain type of cell do not regrow hair. The same technique could shed light on how stem cells interact with other cells and trigger repairs in a variety of other organs, including lung and heart tissue.

“This tells us a lot about how the tissue regeneration process works,” said Valentina Greco, assistant professor of genetics and of dermatology at

Professor suspected of stem cell study fabrication

A stem cell researcher at Seoul National University (SNU) is suspected of fabricating 14 studies submitted to international scientific journals for publication, the school said Monday.

The misconduct of the researcher, if proven to be true, could deal a severe blow to the nation’s efforts to revive its reputation as a world leader in stem cell research following data manipulation in 2005 by then SNU professor Hwang Woo-suk.

“We’re following the matter closely,” a public relations official at the school said. “We are conducting an internal investigation while waiting for the opinion of the international journals.” The researcher is veterinary professor

The Obama era: 58 Mln dollars ready to fund embryonic stem cell research

An agreement on funding stem cell research is closer than previously thought. A change in direction on financing stem cell research by US President Barack Obama has excited the American scientific community, starting with the major universities in California, including the San Francisco State, San Jose’ University, Stanford, and Berkeley. This time it will be the California Institute of Regenerative Medicine (CIRM) to open its wallet, ready to fund grants worth 58 million dollars to groups and researchers studying stem cells.

Patient’s Own Stem Cells Might Treat Heart Attack

Treating a heart attack with the patients’ own bone marrow stem cells boosts blood flow within the heart and may help reduce long-term complications, a new U.S. study finds.
The study included 31 patients who underwent angioplasty and stent placement after a heart attack. Within one week of the attacks, 16 of the patients received infusions of their own bone marrow cells into the coronary artery in which a blockage had caused the event.

The 16 patients received different amounts of bone marrow stem cells — 5 million, 10 million and 15 million cells. The 15 patients in the

US Patients Battle the FDA Over Use of Their Own Cells

American Doctors and Patients Challenge the FDA to Save Lives Rather Than Allow Patients to Needlessly Die
A couple of weeks ago, the American Stem Cell Therapy Association (ASCTA) was formed by a group of doctors, not to debate the pros and cons of embryonic stem cell research and adult stem cell research, but to […]
