Scientists have discovered that "endometrial regenerative cells" (ERC's) -- in other words, human menstrual blood -- contains stem cells. ERC-derived stem cells seem to have a number of superior traits to both bone marrow derived and umbilical cord derived stem cells, the previous gold standards: they can give rise to a variety of different cell lines without differentiation, they multiply more quickly than other stem cells, they are able to replicate more times without adversely mutating, and they apparently do not need to be closely genetically matched to the recipient. Now some women have even begun banking their menstrual blood to preserve their stem cells through a company called "C'Elle: Your Monthly Miracle" -- check out their FAQ and online video. This follows last May's announcement that menstrual blood derived cells can pretty much cure Duchenne Muscular Dystrophy in mice, a disease for which there is no current therapeutic treatment available.

So there's no need to be scared of them anymore. You can buy them in bulk for about $7 a
