Hi Linda, There are several types of hormone-like substances that stimulate bone marrow to produce blood cells, called hematopoietic growth factors. For instance, patients with MDS, if experiencing a reduction in the output of red blood cells, may be given a drug called Erythropoietin (Epo or Procrit), a growth factor that promotes red blood cell production. This may help avoid red blood cell transfusions in some people. There are other forms of this drug as well.

It’s encouraging for you and your doctor to see your hemoglobin rising. You’re probably feeling a little more energetic too. What was the name of the injection you received?
