Fixing Broken Hearts With Menstrual Blood


Could "the curse" become the cure? It could happen, if Japanese scientists have their way. Experiments performed at the Keio University school of medicine have succeeded in growing sheets of heart muscle from connective tissue cells harvested from menstrual blood.


According to Shunichiro Miyoshi, a cardiologist with the Keio University team, cells in women's menstrual blood have properties similar to those of embryonic stem cells, which can transform themselves into a variety of different cell types as the body requires.

When it comes to growing heart muscle, however, the connective tissue cells in menstrual blood have a success rate 100 times higher than the 0.2 - 0.3 percent for stem cells taken from human bone marrow. When the researchers cultured the cells derived from menstrual blood for one month, then placed them in close proximity to rat heart muscle cells cultured in vitro, they were astounded to see the transformed connective tissue cells beating right along with the rat cells!

The long term goal of the research is to duplicate in humans what has been achieved in rats - improvements in heart health following heart attacks in rats who were treated with the cultured cells.


Shunichiro Miyoshi suggests that one day in the future, women will be able to culture their own menstrual blood to create a personalized stockpile of cells. By doing so, they will build up a reservoir of repair cells that will not cause a reaction from the body's immune system.

Well ladies, are you up to this? Comfortable with processing your monthly flood and saving it for a "rainy day"? Would you gladly wear a fashion accessory resembling a red colostomy bag? Don't make that face - the life you save just may be your own. Period. (via TODAYonline)

Importance of this breakthrough

One of the functions of the stem cells from menstrual blood is to make new blood vessels. This is because in the endometrium there are huge numbers of blood vessels made monthly. The abilikty of the menstrual derived stem cells, or as company Medistem calls them, Endometrial Regenerative Cells (ERC), to make new blood vessels could be very useful in cardiology.

Dr. Miyoshi's discovery that they actually become cardiac cells that work in a mouse, combined with Medistem's discovery that they make new blood vessels, suggest these cells are a very potent way of advancing medicine.

People dont realize but stem cells of this type DO NOT NEED matching with the recipient. There is company called OSiris that actually is nearing the end stages of the approval process and is expected to reach the market next year with a universal donor stem cell product. I think that the menstrual derived mesenchymal stem cells like Medistem's and Dr Miyoshi's are better because they appear to have a longer proliferative advantage, at least according to the publications.

Menstrual Stem Cells

Now maybe some doctor somewhere can finally fix the DVT in my left leg, after 33 years of severe pain. Oh god, wouldn`t that be GREAT !!!!!!!
