New oocytes from bone marrow?
The Scientist :: New oocytes from bone marrow?, Jul. 28, 2005
Female mammal eggs can originate in bone marrow!
That is the astounding concept put forth in this article. Among the brilliant steps they took to track down this process, they sterilized wild-type mice, and gave them, and some genetically sterile mice, blood transfusions from fertile mice that have been genetically engineered to express a green fluorescent protein (GFP) from jellyfish, but only in conjuction with a gene marker that occurs in germ or reproductive cells.
Within two days, the fluorescent green oocytes began to appear in the ovaries of the (previously) sterile mice.
