Low oxygen levels prevent X chromosome inactivation in human embryonic stem cells
Oxygen levels in the lab can permanently alter human embryonic stem (ES) cells, specifically inducing X chromosome inactivation in female cells, according to Whitehead Institute researchers. Human ES cells have been routinely ...

Female human embryos adjust the balance of X chromosomes before implantation
Dutch researchers have found the first evidence that a process of inactivating the X chromosome during embryo development and implantation, which was known to occur in mice but unknown in humans, does, in fact, take place ...
