For example, aggressive animals had increased activity of some genes for sensing dopamine. (sciencenews.org)
The sex of the stem cells could also be significant, because activity of some genes varies between males and females. (sciencemag.org)
A team from the Centre for Trophoblast Research, which this year celebrates its tenth anniversary, was able to grow the organoids in culture from cells derived from endometrial tissue and maintain the organoids in culture for several months, faithfully reproducing the genetic signature of the endometrium — in other words, the pattern of activity of genes in the lining of the uterus.
