Alkaline phosphatase (ALP) activity, qRT-PCR analysis of ALP and RUNX2, and alizarin red S stain. A Quantification of DNA and ALP following 2 weeks of cultivation in osteogenic differentiation media. B Relative mRNA expression of osteogenic genes in each group. C Alizarin red staining reveals the production of calcium during osteogenic differentiation. p < 0.05 compared to the HAp (*), Qct (†), and BMP-2 (‡) groups
