Stem cell research: miracle cells reproducible from menstrual blood?
Japanese, US, Dutch and Australian scientists are researching the production of new stem cells from menstrual blood for people with conditions such as leukemia, infertility (in women), cervical cancer, circulatory disorders, heart attack, heart failure and other cardiovascular diseases. The cells from the menstrual blood are part of the endometrium. It is regularly built up in the shortest possible time as part of the woman's cycle by the organism with many new blood vessels. The researchers would like to use the qualities of the speed of assembly and the resulting high number of blood vessels in the future. And yet another point makes a woman's menstrual blood interesting for use in treatment: the cells are neutral cells. Our immune system does not recognize them as foreign, just like the umbilical cord blood.
The advantage over previous stem cell therapies from bone marrow would then be the non-existent defense reaction and the rapid new formation of blood vessels. Australian gynecologist Caroline Gargett is a pioneer in the field. At the Monash Medical Center in Clayton, Australia, she detected stem cells in the menstrual blood. She is still cautious about the German science magazine "bild der Wissenschaft" (bdw). Further studies should first show what potential these cells really have and how they can be used by us at all.
Because there is currently no thoroughly tested therapy with these cells. Menstrual bleeding is not only seen in natural medicine as a detoxification of the body. Caroline Gargett also points out that there are "an unbelievable number of bacteria" in the mentoring blood: Therefore, the cell cultures must be treated with high doses of atibiotics in advance.
The American company Medistem from Arizona, meanwhile, according to company researcher Thomas Ichim against bdw, is now planning the first clinical study in patients with circulatory disorders. The background to the efforts are experiments on mice in 2008: They had a femoral artery cut. After the cells obtained from menstrual blood were injected, they were able to walk again because new blood vessels formed.
Further research And there are other reasons that give hope for the future, because Dutch researchers at the Utrecht University Medical Center evaluated 18 clinical studies on the subject and described the results as "promising". In 2009, Medistem published an article in the journal Journal of Translational Medicine, in which 4 test subjects with multiple sclerosis tolerated the cells well and showed no response.
Meanwhile, according to Carolin Gargett, there are researchers in Japan and the USA who are working on the further research, so that one day the power of these cells can be used for us. In Germany, unfortunately, the subject currently seems to be overslept. (Thorsten Fischer, naturopath osteopathy, January 20, 2010)
