Low Blood Cell Counts Could Be Treated by Regulating Stem Cells.

Megakaryotes may hold the ability to regulate the amount of blood that stem cells produce.

According to new research from the Stowers Institute for Medical Research, hematopoietic stem cells [stem cells that produce blood] are directly regulated by megakaryocytes, the blood cells responsible for healing wounds.  The researchers found that megakaryotes produce two growth factors; one that signals for hematopoietic stem cells to proliferate, and one that keeps them in an inactive state.  This relationship controls the amount of blood being produced in the body.
