Mesodermal differentiation potential of MSCs. No donor age or gender related differences could be detected for the adipogenic, osteogenic and chondrogenic in vitro differentiation capacity of the MSC preparations as analysed by lineage specific staining (Oil Red O for adipogensis; Alizarin Red for osteogenesis, and Safranain O for chondrogenesis (n = 40); differentiation: A, C, E; negative controls: B, D) and no statistically significant differences could be detected for the lineage specific mRNA expression (LPL (n = 44) and PPARγ (n = 48) for adipogenesis; OPN (n = 17) and AP (n = 41) for osteogenesis; SOX9 (n = 47) and COLL2 (n = 32) for chondrogenesis; F-Q). Two-tailed Student’s t-test and Spearman two-tailed correlation test. Error bars: SD. Scale bars: 100 μm.
