LLLT promoting osteogenic potential of the co-cultured hBMSCs and HUVECs in late stage of osteogenic induction. A HUVECs, hBMSCs, and the co-cultured hBMSCs and HUVECs were stained with Alizarin Red S (ARS) at 14 days and 21 days after osteogenic induction. B, C Quantification of the ARS staining by MOD at 14 days and 21 days. D, E The expression of the osteogenic genes (ALP, RUNX-2, OCN) was measured by RT-qPCR at 14 days (D) and 21 days (E) after osteogenic differentiation (ns, not statistically significant, *P < 0.05, **P < 0.01, ***P < 0.001)
