Abstract from journal Cell on stem cells

This is off topic, but there's big news today regarding the
creation of pluripotent cells from human skin fibroblasts.
Here's the abstract from the Yamanaka study in Cell:
"Successful reprogramming of differentiated human
somatic cells into a pluripotent state would
allow creation of patient- and disease-specific
stem cells. We previously reported generation
of induced pluripotent stem (iPS) cells, capable
of germline transmission, from mouse somatic
cells by transduction of four defined transcription
factors. Here, we demonstrate the
generation of iPS cells from adult human dermal
fibroblasts with the same four factors: Oct3/4,
Sox2, Klf4, and c-Myc. Human iPS cells were
similar to human embryonic stem (ES) cells in
morphology, proliferation, surface antigens,
gene expression, epigenetic status of pluripotent
cell-specific genes, and telomerase activity.
Furthermore, these cells could differentiate
into cell types of the three germ layers in vitro
and in teratomas. These findings demonstrate
that iPS cells can be generated from adult
human fibroblasts."
