It is said that menstrual blood can also be used to store stem cells. Is it true?/You don't say.

Women's uterus will periodically proliferate and fall off under the action of hormones in the body every month. Its strong vitality and regenerative ability stem from its abundant stem cells, namely endometrial stem cells, which can inject new vitality into aging, pathological and damaged tissues. When storing, it is recommended to choose a large company, which is more reliable. Don't save it. If it is useless when needed, it is a waste of money. For example, I exist in Evans Company in Hangzhou. At the beginning of its establishment, Evans introduced the patent of endometrial stem cells from American stem cell company, and now it has been transformed into its own patent, which is also a major feature project. Baidu answered seriously, I hope you are satisfied.
