Researchers create sperm from embryonic stem cells
Researchers at Kyoto University in Japan have created fully functioning sperm from mouse embryonic stem cells. The sperm cells were able to fertilize mouse eggs in vitro, and when the scientists implanted the embryos into surrogate mothers, the mice gave birth to healthy offspring. The research, published in the journal Cell, may someday help treat infertility in humans.
The need and value of studying human stem cells keeps getting more and more apparent.
