Several scientists have discovered in the bone marrow a stem cell capable of transforming any tissue or organ of the mammalian body. Until recently it was thought that bone marrow cells could only become blood cells. In recent years, however, scientists have shown that they can develop into muscle cells, bones, brain and other organs.

The research was conducted among researchers from the New York University Schools of Medicine, Yale and John Hopkins. First the stem cells of the bone marrow of a male mouse were purified. Subsequently, several females were subjected to a previously purified stem cell transplant process to remove the bone marrow by radiation. Eleven months later, they saw that the male cells adapted well to the female blood and bone marrow.

To confirm this, we identified the Y chromosome that only appears in the cells of the males and, in addition to the blood and bone marrow, in the lungs, esophagus, lung stomen, esophagus, stomachs, intestines, livers and skin tissues. Now they want to study the mechanism of transformation of cells to look for treatments to combat various diseases.
