Testosterone increases red blood cell production, said Dr. Mark Tarnopolsky, an exercise researcher at McMaster University in Ontario.
The secretions of several endocrine glands influence red cell production.
The concept of using cytokines to stimulate adult stem cell production is already in use in bone marrow transplants.
Amgen says there is no convincing evidence that Epo does anything in the body besides spur red blood cell production.
A gene that controls red blood cell production evolved quickly to enable Tibetans to tolerate high altitudes, a study suggests.
Likewise, domestic fuel cell production — which will undoubtedly have many critical military applications — depends on a vibrant car industry.
The theory goes that an imbalance in serotonin levels – caused by low brain cell production of serotonin – equates to depression.
This in turn affects red blood cell production: the cells divide, but their nuclei remain immature.
When oxygen needs are satisfied, erythropoietin production is reduced and red cell production diminishes.
EPO is given to patients with conditions that hamper red blood cell production -- usually people being treated for kidney problems, like dialysis patients, or for cancer.
