Scientists Identify Critical Process in Stem Cell Development

Scientists at the Gladstone Institutes have discovered that environmental factors critically influence the growth of a type of stem cell — called an iPS cell — that is derived from adult skin cells. This discovery offers newfound understanding of how these cells form, while also advancing science closer to stem cell-based therapies to combat disease.

Researchers in the laboratory of Gladstone Senior Investigator Shinya Yamanaka, MD, PhD, have for the first time shown that protein factors released by other cells affect the “reprogramming” of adult cells into stem cells known as induced pluripotent stem cells, or iPS cells. The scientists

“Stem cell revolution” movie

Featuring beautiful hand-drawn animations and interviews with leading stem cell scientists, STEM CELL REVOLUTIONS charts the history and scientific evolution of stem cell research – from the earliest experiments that first revealed stem cells in the body, to leading current scientific and clinical developments.

Supported by the Wellcome Trust and made by the same team as behind our four short films, Stem Cell Stories, this documentary is a genuinely creative collaboration between scientists and filmmakers.

STEM CELL REVOLUTIONS features eminent international scientists in stem cell research including Nobel Laureate Sir Martin Evans and Sir Ian Wilmut, creator of Dolly the sheep,

Researchers cure mice with damaged spines using human iPS cells

A team at Keio University has used stem cells to cure mice whose hind legs were paralyzed due to spinal cord damage, the researchers reported Wednesday at a Tokyo symposium.
The team transplanted neural stem cells grown from human iPS cells.

Team leader Hideyuki Okano, a physiology professor at Keio, said it is the first time in the world in which the curative effects of “induced pluripotent stem cells,” or iPS cells, have been confirmed.
Currently, there is no effective treatment for spinal nerve damage and treatment using iPS cells gives hope of a cure.

“It is valuable that treatment using human iPS

Wide-ranging applications for pluripotent stem cells

While applications of induced pluripotent stem cells in stem cell therapy may be limited to a few diseases, its applications in drug discovery are wide-ranging, and many more diseases can be targeted, Shinya Yamanaka, Director, Centre for iPS Cell Research and Application, Japan, has said.

The Japanese scientist, whose breakthrough was the creation of embryonic-like stem cells from adult skin cells, believes that the best chance for stem cell therapy lies in offering hope to those suffering from a few conditions, among them, macular disease, Type 1 Diabetes, and spinal cord injuries.

On the other hand, there were multiple possibilities with

StemCells can avoid rejection from the immune system

Last year, Japanese researchers announced that the first human patient would be treated with induced pluripotent stem cells in an attempt to reverse a degenerative eye condition called macular degeneration that leads to vision loss.

Now, a team of scientists headed by biologists at UC San Diego has discovered how induced pluripotent stem (iPS) cells, which are derived from an individual’s own cells, could be programmed to avoid rejection from the immune system.

Their findings, published online ahead of print in the journal Cell Stem Cell, show that iPS cells can differentiate or change into various types of functional cells with
