Quartet of genes controls growth of blood stem cells

An important element in getting blood stem cells to multiply outside the body is to understand which of the approximately 20,000 genes in the human body control their growth. A research team has studied close to 15,000 of these genes alongside each other. The researchers have succeeded in identifying four key genes which, together, govern the growth and multiplication of the stem cells. (Mehr in: Cancer News — ScienceDaily)
