Effects of NR4A2 overexpression on osteogenesis in hPDLMSC spheroids. (a, b) Confirmation of overexpression of NR4A2 in spheroid-cultured hPDLMSC. Transfection of NR4A2 overexpression vector increased NR4A2 protein expression in monolayer and spheroid-cultured hPDLMSCs. (c) Effects of NR4A2 overexpression on ALP, OPN, Col1, and RUNX2 mRNA expression in spheroid hPDLMSCs cultured with OIM. On day 7, the expression of ALP, OPN, Col1, and RUNX2 mRNA was examined by real-time RT-PCR. (compared with control). (d) Effects of NR4A2 overexpression on ALP activity in spheroid-cultured hPDLMSCs cultured with OIM. On day 7, ALP activity was measured. (compared with control). All experiments were performed with samples from four donors.
