Introduction

The formation & development of blood cells, including:

In adults, hematopoiesis is restricted to the pelvis, sternum & vertebrae.

Physiology

  • hematopoiesis in adults <65 years of age is massively polyclonal[2]
  • in adults >75 years, 30-60% of haematopoiesis is accounted for by 12-18 independent clones, each contributing 1-34% of blood production[2]
