Oxygen tension-mediated regulation of chondrogenic differentiation: application to stem cells based osteochondral repair

Purpose: Multipotent stromal cells (MSC) have been considered promising for the regenerative strategies of articular cartilage. However, the MSC chondrogenic differentiation can ultimately lead to the formation of hypertrophic chondrocytes responsible for the calcification of cartilage. To prevent this MSC-dependent production of a calcified matrix in articular site, MSC hypertrophic differentiation has to be carefully controlled. Given that articular cartilage is avascular, w...

Purpose: Multipotent stromal cells (MSC)-based regenerative strategy is promising for the repair of cartilage, which is an avascular tissue in which cells experience hypoxia. Hypoxia is known to promote the early chondrogenic differentiation of MSC. Therefore, the aim of our study was to determine whether low oxygen tension could be used to enhance the regenerative potential of MSC for cartilage repair.Methods: MSC from rabbits or human adipose tissues (...
