To Warm a Mother’s Heart

NPR’s stories usually make me snicker, but today on Morning Edition they had an interesting, and beautiful, piece. It was about how scientists have hypothesized that baby cells stay with a mother for many years, perhaps the rest of her life. Even from babies that have been miscarried. The wonderful and beautiful part of it comes in here: these fetal cells have been shown to rush to damaged areas of the mother’s body and repair and defend it. There’s also a “bad hypothesis” where the cells may be responsible for the rarer diseases that occur disproportionally in females. The “good hypothesis” is being supported in research though, while evidence doesn’t seem to support the bad one. You can read more about it and/or listen to the original broadcast on
