Figure 7. MPMCA does not induce the upregulation of osteogenic markers in osteoblasts. (A–D) MC3T3-E1 cells were subjected to predetermined concentrations of MPMCA for a period of 24 hours. RT-qPCR test was performed to examine the mRNA levels of osteogenic markers (n = 3). *p < 0.05 vs. control group.
