an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.

Embryonic stem cells (ES cells) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage preimplantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells.

Scientists in Japan showed stem cells can now be made quickly just by dipping blood cells into acid.

In female mammals, one of the two X chromosomes is inactivated. Thanks to research using special stem cells, geneticists have been able to provide detailed insight into the molecular mechanism behind this inactivation process.

Researchers have for the first time developed a method to precisely control embryonic stem cell differentiation with beams of light, enabling them to be transformed into neurons in response to a precise external cue.
