2. Fig. 1
Relative gene expression levels of unstrained hMSCs (Co). Each symbol represents one of 10 sex- and age-matched donors. The figure demonstrates transcriptional heterogeneity and pronounced donor-to-donor variance in hMSCs.

Response of hMSCs to CTS. All mRNA expression levels of the chondrogenic and osteogenic marker genes were significantly up-regulated in the response to CTS (P<0.05), with the exception of FOS (P=0.105).
