It has been well established that blood and bone share a unique, regulatory relationship with one another, though the specifics of this relationship still remain unanswered. Erythropoietin (Epo) is known primarily for its role as a hematopoietic hormone. However, after the discovery of Epo receptor outside the hematopoietic tissues, Epo has been avidly studied for its possible nonhematopoietic effects. It has been proposed that Epo interacts with bone both directly, by activating bone marrow stromal cells, and indirectly, through signaling pathways on hematopoietic stem cells. Yet, the role of Epo in regulating skeletal maintenance and regeneration remains controversial. Here, we review the current state of knowledge pertaining to the effects of Epo on the skeleton.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
