Comparison between samples of HSP70 knockdown and controls in terms of ALP activity (A), calcium deposition (B) and real time PCR data of gene expression of Runx2 (C) and Osterix (D) during osteogenic differentiation in hMSCs. One enzyme unit of ALP is the amount of enzyme which releases 1 nmol p-nitrophenol per 15 minutes. Each sample had 104 seeded hMSCs. N = 4. S: scrambled; KD: HSP70 knockdown; HS: heat shock. *P < 0.05; **P < 0.01.
