Fig. 4From: SFRP2 enhances the osteogenic differentiation of apical papilla stem cells by antagonizing the canonical WNT pathwaySFRP2 decreased the expression of Wnt target genes in SCAPs. a, b Real-time RT-PCR showed that the depletion of SFRP2 upregulated the expression of AXIN2 and MMP7. c, d Real-time RT-PCR results showed that the overexpression of SFRP2 decreased the expression of AXIN2 and MMP7. Student’s t test was performed to determine statistical significance. All error bars represent SD (n = 3). *p ≤ 0.05, **p ≤ 0.01Back to article page
