Latest Pluripotency Stories
In an effort to sidestep the ethical dilemma involved in using human embryonic stem cells to treat diseases, scientists are developing non-controversial alternatives: In particular, they are looking for drug-like chemical compounds that can transform adult skin cells into the stem cells now obtained from human embryos.
The great promise of induced pluripotent stem cells is that the all-purpose cells seem capable of performing all the same tricks as embryonic stem cells, but without the controversy.
Biologists at UC San Diego have identified the specific region in vertebrates where adult blood stem cells arise during embryonic development.
DURHAM, N.C., Feb. 11 /PRNewswire/ -- For the first time, scientists have performed a detailed long-term evaluation and comparison of two different types of pluripotent stem cells: human embryonic stem cells (hESC) and induced pluripotency stem cells (iPSC).
In the Feb 7 issue of the journal Nature, scientists at the Genome Institute of Singapore (GIS), report that a genetic molecule, called Tbx3, which is crucial for many aspects of early developmental processes in mammals, significantly improves the quality of stem cells that have been reprogrammed from differentiated cells.
SOUTH SAN FRANCISCO, Calif., Jan.
Scientists at the Stanford University School of Medicine have succeeded in the ultimate switch: transforming mouse skin cells in a laboratory dish directly into functional nerve cells with the application of just three genes.
New Method Bypasses Need to Obtain Stem Cells From Embryos WHITE PLAINS, N.Y., Jan. 26 /PRNewswire-USNewswire/ -- The scientist who reprogrammed adult cells into embryonic-like stem cells has been chosen to receive the 2010 March of Dimes Prize in Developmental Biology.
ALISO VIEJO, Calif., Jan. 20 /PRNewswire/ -- Ambry Genetics today introduces their new StemArray(TM) product and services utilizing aCGH technology to cover the entire genome. The Ambry StemArray(TM) offers a higher resolution approach to standard karyotyping for stem cells at comparable costs.
Tissue-specific genes, thought to be dormant or not marked for activation in embryonic stem cells, are indeed marked by transcription factors, with proper marking potentially crucial for the function of tissues derived from stem cells.
