Mouse Reproduction

News today has spread about new stem cell research out of China. Two teams used mouse fibroblasts, a kind of cell found in skin connective tissues, to create induced pluripotent skin cells (iPS), which were then used to create living mice. Their breakthrough research suggests that both cloning full animals from stem cells and the creation of completely pluripotent stem cells from skin cells are both not only possible, but a current reality. The two teams published separately, in Nature and Cell - Stem Cell, both very prestigious journals. The first task for either study was to create stem…
How many times have you heard a guy say "Women - can't live with them, can't live without them." Well, they just might be onto something. At least kind of. You see, living with a woman might just make you fertile longer. New research published in Biology of Reproduction has found that male mice stay reproductively active longer if they live with a female mouse than if they live alone. The study, from the University of Pennsylvania School of Veterinary Medicine, sought to see whether living with a female mouse had any affect on a male mouse's fertility as he aged. To do this, male mice were…
