Biocompatibility of CGF and iRoot BP Plus extract in hDPSCs. A The proliferation of hDPSCs stimulated by 25% BP, 50% CGF and CGF-iRoot BP Plus. B Effects of 50% CGF, 25% BP, and CGF-iRoot BP Plus on the cell cycle of hDPSCs. C Flow cytometry to evaluate the cell cycle in hDPSCs after treatment with 50% CGF, 25% BP and CGF-iRoot BP Plus. D Effects of 50% CGF, 25% BP and CGF-iRoot BP Plus on the apoptosis rate of hDPSCs. E Flow cytometry analysis of the apoptosis rate of hDPSCs after treatment with 50% CGF, 25% BP and CGF-iRoot BP Plus. (*: P < 0.05, compared with the NC group, **: P < 0.01, compared with the NC group, #: P < 0.05, compared with the CGF-iRoot BP Plus group, ##: P < 0.01, compared with the CGF-iRoot BP Plus group)
