Upregulation of Runx2 and Osterix during in vitro chondrogenesis of human adipose-derived stromal cells.

ABSTRACT: The aim of this study was to create a gene expression profile to better define the phenotype of human adipose-derived stromal cells (HADSCs) during in vitro chondrogenesis, osteogenesis and adipogenesis. A novel aspect of this work was the analysis of the same subset of genes during HADSC differentiation into all three lineages. Chondrogenic induction resulted in increased mRNA expression of Sox transcription factors, COL2A1,COL10A1, Runx2, and Osterix. This is the first report demonstrating significant upregulation in expression of osteogenesis-related transcription factors Runx2 and Osterix by TGF-beta3 induction of HADSCs during in vitro chondrogenesis. These findings suggest that the commonly-used chondrogenic induction reagents promote differentiation suggestive of hypertrophic chondr
