New Strategy Advances Stem Cell Culture Techniques

Stem cells – unspecialized cells that have the potential to develop into different types of cells – play an important role in medical research. In the embryotic stage of an organism’s growth, stem cells develop into specialized heart, lung, and skin cells, among others; in adults, they can act as repairmen, replacing cells that have been damaged by injury, disease, or simply by age.

Given their enormous potential in future treatments against disease, the study and growth of stem cells in the lab is widespread and critical. But growing the cells in culture offers numerous challenges, including the constant need

Stem Cells for Patients with Erectile Dysfunction

After more than a decade of short-term cures to erectile dysfunction, most aimed at symptoms rather than the underlying issues of nerve damage, a new approach has emerged from adult stem cell technology developed by RNL Bio. Dr. Ji Youl Lee and the RNL Stem Cell Technology Institute team, working at St. Mary’s Hospital in Seoul, found in animal studies that adipose (fat) derived adult human stem cells, grown in culture, were very effective in treating cavernous nerve injury.

When rats with cavernous nerve injury, the equivalent of erectile dysfunction in humans, were treated with RNL Bio’s patented

Stem cell therapy works in blind patients in first trial

Scientists have improved the sight of two people who were almost blind by injecting their eyes with stem cells from embryos.

The two women, both registered as blind, saw their vision improve in a matter of weeks after being given the embryo-derived cells in the US safety trial.

The breakthrough holds out the hope of a cure in the future for age-related macular degeneration, which currently affects some 500,000 people in Britain.
The results, published this week in The Lancet, provide a major boost for the field of stem cell reseach.

Stanford creates first PhD program in stem cell science

Stanford University’s Faculty Senate today approved the creation of what officials believe is the first PhD program devoted solely to stem cell science in the nation and, perhaps, the world. The new doctoral program in stem cell biology and regenerative medicine is also the first interdisciplinary doctoral program created by the School of Medicine in recent years.

School officials say the fact that the university is taking the rare step of creating a new doctoral program acknowledges the growing importance of stem cell research in the realm of biomedical science. The senate’s initial approval

“Liposuction leftovers” easily converted to induced pluripotent stem cells

Globs of human fat removed during liposuction conceal versatile cells that are more quickly and easily coaxed to become induced pluripotent stem cells, or iPS cells, than are the skin cells most often used by researchers, according to a new study from Stanford’s School of Medicine. The findings were published online Monday in the Proceedings of the National Academy of Sciences.

“We’ve identified a great natural resource,” said Stanford surgery professor and co-author of the research, Michael Longaker, who has called the readily available liposuction leftovers “liquid gold.” Reprogramming adult cells to function like embryonic stem
