Cell-specific expression of circRNAs (a), the potential role of circRNAs as a miRNA sponge (b) and the circRNA-miRNA network (c) during osteogenic differentiation. (a) A Venn diagram showing the expression pattern of circRNAs in hPDLSCs, hDPSCs and hGFs (or tissue). (b) The function of circRNAs when they act as miRNAs sponges. (c) The mechanism of circRNAs in osteogenic differentiation for hPDLSCs, hGFs, and hDPSCs exerted via a circRNA-miRNA network.
