The race to understand--and profit from--period blood. MetaFilter By: Kitteh 3 July 2024 at 11:12 Other researchers are examining period blood's potential to treat diseases. The uterus is an incredible organ for many reasons, chief among them is that it repairs itselfβwithout scarringβafter shedding its tissue every month or so during a person's reproductive years. It does this with the help of stem cells, some of which are present in menstrual effluent. There have recently been clinical trials testing the use of these stem cells for conditions such as infertility and severe Covid, and studies showed they helped with wound healing and stimulating insulin production in diabetic lab mice.
