Scientists Claim To Discover That Mice Can Produce Eggs After Birth
A new study by Chinese scientists challenges the standard medical view that women are born with all the egg cells they will ever produce. The Chinese team, led by Kang Zou and Ji Wu of Shanghai Jiao Tong University, claim to have detected the germ-line cells that produce unfertilized eggs, or oocytes, in both young and old mice. These germ-line cells were removed, marked with a green fluorescent protein, grown in a laboratory setting, and then injected into female mice that were sterilized. When the mice were bred, they produced green offspring indicating these offspring were produced from the marked germ-line cells. Other researchers claim the results are exciting, but are careful in calling for the results to be independently reproduced. For more information, see here.
