Tiny circles of DNA are the key to a new and easier way to transform stem cells from human fat into induced pluripotent stem cells for use in regenerative medicine, say scientists at the Stanford University School of Medicine.

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.

Two scientists at the Stanford University School of Medicine who've sussed out ways to see what's usually hidden are winners of this year's NIH Director's Pioneer Awards--the National Institutes of Health's most prestigious award for creative thinkers.

Human embryonic stem cells trigger an immune response in mice, researchers from the Stanford University School of Medicine report. The finding suggests that the effectiveness of human therapies derived from the cells could be limited unless ways are found to dampen the rejection response.
