Mechano-hypoxia conditioning with TGF-β3 withdrawal promotes stable, non-hypertrophic chondrogenesis of human mesenchymal stem cells


ABSTRACT: We hypothesize that the combination of mechanical loading with hypoxia culture and TGF-β3 growth factor withdrawal will promote stable, non-hypertrophic chondrogenesis of hBM-MSC embedded in an HA-hydrogel. To this end, we first assessed static hypoxia culture with growth factor withdrawal against static normoxia (20% O2) culture at the global transcriptome and tissue matrix level. We then assess two modalities of mechanical loading (dynamic compression, DC and cyclic hydrostatic pressure, CHP) with growth factor withdrawal against static culture, all under hypoxia. Results showed that Mechanical stimulation and TGF-β3 withdrawal under hypoxia promoted a strong chondrogenic and non-hypertrophic phenotype of hBM-MSC.
