Stems cells from menstrual blood help treat damaged womb tissue

A scientist in Wichita, Kansas, has claimed that e has identified a new type of stem cell that can be reproducibly isolated rom menstrual blood collected from healthy female subjects.

Washington, Nov 15 : A scientist in Wichita, Kansas, has claimed that e has identified a new type of stem cell that can be reproducibly isolated rom menstrual blood collected from healthy female subjects.

"We have many problems with our current methods of stem cell therapy, like hose taken from bone marrow. They may be rejected by the recipient and/or ave limited potential to generate new tissue. Now we've found a possible ew way to overcome these difficulties by using cells from menstrual blood," aid Dr. Xiaolong Meng of the Bio-Communications Research Institute in ichita, Kansas.

Cells collected from the menstrual blood of women include types which can be ultured in the laboratory, which replicate almost 70 times in a very rapid ime span.

This replication rate is far faster than cells, which are currently used, aken from umbilical cord blood and bone marrow.

Meng's study has found that cells that thicken the womb wall during a oman's menstrual cycle contain a newly discovered type of stem cell, which ight be used in the treatment of damaged and/or old womb tissue.

The cells are so unique in their ability to develop into at least nine ifferent cells, including heart, liver and lung, that researchers call ndometrial Regenerative Cells (ERC).

Not only do ERC replicate at a phenomenal rate of almost every 20 hours, but hey also they produce unique growth factors at a rate of almost 100,000 reater than cells from umbilical cord blood.

A mere 5ml of menstrual blood collected from a healthy woman provided enough ells which after two weeks of culture provided beating heart cells.

The researchers suggest that the cells could be cultured at a large scale, hereby providing an alternative to the current methods of using bone marrow nd umbilical cord blood, which itself poses threats of rejection.

The study is published in the Journal of Translational Medicine.
