Pfizer said Sunday that it was buying the rights to a somewhat controversial cell therapy from Athersys, a biotechnology company — a sign of big pharmaceutical companies’ growing interest in stem cells (…)
The relatively small payment reflects that “it’s really early for cell therapy and there’s more research to be done,” said Ruth McKernan, chief scientific officer of Pfizer Regenerative Medicine, a unit created by the company about 18 months ago to develop treatments based on stem cells (…)
Deep in the brain, buried in the hippocampus and subventricular zone, reside adult neural stem cells, cells that retain the ability to become other types of neural cells and could serve as possible treatments for ailments ranging from vision impairment to Parkinson’s to spinal cord injuries. Doctors, scientists and patients, however, are understandably hesitant to go digging around for them, their location being “a great deterrent,” Sally Temple, founder of the New York Neural Stem Cell Institute, said at the 2009 World Stem Cell Summit here on Wednesday.
Researchers, therefore, are anxious to uncover other, more accessible neural stem cell

The coordinator of the health commission of the Federal-Regional government conference, Enrico Rossi, spoke about the statements made by Undersecretary for Healthcare Ferruccio Fazio on the stem cell ban.
“In the Federal-Regional conference, which met on February 26,” said Rossi, Healthcare Councilman of Tuscany, “the agreement on the Employment, Healthcare, and Social Policy Minister’s proposal between the federal government, the regions, and the autonomous provinces of Trento and Bolzano for 2008 regarding stem cell research, was ratified unanimously, and in that meeting, there were no requests to modify the text in a technical meeting between
“For centuries, scientists have known that certain animals can regenerate missing parts of their bodies. Humans actually share this ability with animals like the starfish and the newt. Although we can’t replace a missing leg or a finger, our bodies are constantly regenerating blood, skin, and other tissues.
The identity of the powerful cells that allow us to regenerate some tissues was first revealed when experiments with bone marrow in the 1950s established the existence of stem cells in our bodies and led to the development of bone marrow transplantation, a therapy now widely used in medicine.
This discovery raised
Adult stem cells tested for defects before being implanted in the injured spinal cords of mice helped the animals recover with no cancerous side effects, according to new research. In recent years, scientists found that some experimental stem cell therapies can cause cancerous tumors. Pre-screened cells could result in potentially life- saving treatments without such side effects.
These new findings were presented at Neuroscience 2009, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health. “We tried to identify induced pluripotent stem cells from adult tissue that would be
