Abstract

Trabecular bone fragments from femoral heads are sometimes used as bone grafts and have been described as a source of mesenchymal progenitor cells. Nevertheless, mesenchymal stromal cells (MSC) from trabecular bone have not been directly compared with MSC obtained under standard conditions from iliac crest aspiration of the same patients. This is the ideal control to avoid inter-individual variation. We have obtained MSC by a novel method (grinding bone fragments with a bone mill without enzymatic digestion) from the femoral heads of 11 patients undergoing hip replacement surgery and compared them with MSC obtained by standard iliac crest aspiration of bone marrow from the same patients. We have shown that trabecular bone MSC obtained by mechanically fragmented femoral heads fulfil the immunophenotypic and multilineage (adipogenic, osteogenic and chondrogenic) differentiation criteria used to define MSC. We have also differentially compared cellular yields, growth kinetics, cell cycle assessment, and colony-forming unit-fibroblast content of MSC from both sources and conclude that these parameters do not significantly differ. Nevertheless, the finding of slight differences, such as a higher expression of the immature marker CD90, a lower expansion time through the different passages, and a higher percentage of cycling cells in the trabecular bone MSC, warrants further studies with the isolation method proposed here in order to gain further knowledge of the status of MSC in this setting.
