Quantitative Assessment of the Yield of Osteoblastic Connective Tissue Progenitors in Bone Marrow Aspirate from the Iliac Crest, Tibia, and Calcaneus

The study demonstrated that osteogenic progenitor cells are available in bone marrow aspirate harvested from the tibia or calcaneus as well as the iliac crest. All three sites are easily accessed, with a low risk of adverse events. However, larger volumes of aspirate may be needed from the tibia or calcaneus to approach the yield of cells from the iliac crest.
