Scientists have always thought that bone marrow fat cells only space and no other adverse effects, but American scientists recently announced that the fat cells will significantly slow down the bone marrow to form new blood cells speed, therefore, reduce the number of fat cells may help to accept the bone marrow transplant for cancer patients faster recovery, related to study published in the latest issue of the publication of" Nature "magazine.

by the United States George Daley, Harvard Medical School led the research team found that if the genetically modified mice so that they can make bone marrow fat cells, then, these mice to more effectively to create blood cells. The researchers also found that in the laboratory, inhibition of fat cell formation of compounds can significantly improve the mice's ability to manufacture blood cells.

at birth, full of bone marrow cells to produce blood, but with age, growth, invasion of bone marrow fat cells slowly, "Hatoyama accounted for magpie nests", slowed down the emergence of blood cells.

Daley and colleagues in mice carried out a series of experiments, they found relatively high in fat cells of the mouse tail bones, only 25% of the stem cells can form blood; and other parts of the body bone, 75% of the blood stem cells capable of producing.

researchers used mice fat cells inhibit the formation of compounds, or genetically modified mice so that fat cells can not form, the study found that mice bone marrow can grow faster, even if they are bone marrow After the radiation has been removed. These mice are better able to produce blood progenitor cells, these blood progenitor cells for bone marrow transplant patients after recovery is very important.
