Through the use of stem cells of the bone marrow and of the blood, the mice have refilled the ovaries that had exhausted or almost exhausted, that is, they have managed to form precursor cells of the egg in the ovary.

For the research, researchers from the Massachusetts General Hospital and the Harvard Medical School of the United States used ovule lost mice ovaries due to chemotherapy. Stem cells were injected, which apparently received an improvement at twenty-four hours, and in two months could not separate an ovary that had been treated and treated with ovarian chemotherapy from a healthy mouse.

This research has given a boost to a debate on the reproduction of women: it is not clear that the ovary is able to build new oocytes throughout life, although until recently it has been considered safe. On the other hand, it can be seen if the obocytes of mouse that have obtained in the investigation are going to be able to mature, that is, to become ovules and, therefore, capable of reproducing. This is the objective of the researchers.
