It is still unknown where from osteoblasts are recruited during remodeling of adult human cancellous bone. Still, it is often suggested that they originate from perivascular osteoprogenitors in the bone marrow (BM). Here we propose also the existence of a layer of osteoprogenitors at the periphery of the BM. This proposal is based on electron and light microscopy of the bone surface and of the neighboring BM in human iliac crest biopsies, where we quantified cell densities, ce...
