During the reproductive years, females have menstruation as a part of their menstrual cycle, when their uterine lining is shed if pregnancy did not occur.
The ability of the uterine lining to re-grow quite fast after menstruation was long questioned by scientists with some of them suspecting that stem cells could be the cause.
Xiaolong Meng of the Bio-Communications Research Institute,conducted a private study in institute in Witchita, Kansas examined cells taken from the menstrual blood of two women and found that stem cells are indeed present in the endometrial tissue.
Scientists revealed that these cells could not only replicate themselves, but also develop into other cell types under certain conditions. Endometrial cells also have similar surface to those of stem cells.
The research team examined the way these cells replicated and said that was even faster than stem cells from umbilical chord.
During the experiments scientists managed to grow nine different types of cells, including heart, liver and lung cells. This gives a great potential for stem cell therapy.
While other methods of regenerative therapy can be rejected by the recipient, cells taken from menstrual blood is seen as better solution.
The U.S.-based company was already started to appeal to women to collect and preserve their menstrual blood for regenerative medicine.
The results of the study are published in the Journal of Translational Medicine.
