Mice Save the Day

Did you know that a mouse’s testicles can produce stem cells similar to embryonic stem cells in humans? Embryonic stem cells are cells that can grow into any type of cell found in the body, which can create new tissue and cure various ailments. While more research needs to be done, this means that — at least for men — mice could possibly provide a limitless supply of fresh stem cells customized to a man’s individual genetic makeup. While the ethical debate over stem cell research continues, this new discovery could be a more widely accepted approach, compared to the more controversial one of using human embryos. So, maybe we should put our brooms away and let these mice stay awhile!
