Fig. 7From: Promotion effect of apical tooth germ cell-conditioned medium on osteoblastic differentiation of periodontal ligament stem cells through regulating miR-146a-5pReal-time PCR analysis of osteoblast differentiation-related gene expression. The mRNA expression of ALP (A) and BSP (B) was significantly increased after 7 days in co-culture with APTG-CM, while the mRNA expression of PLAP1 (C) was significantly decreased after 7 days in co-culture with APTG-CM. Data were as mean ± S.D. (n = 3). **P < 0.01; ***P < 0.001Back to article page
