Fig. 1From: miRNA-21 promotes osteogenesis via the PTEN/PI3K/Akt/HIF-1α pathway and enhances bone regeneration in critical size defectsExpression of osteogenic mRNAs in BMSCs in vitro. After BMSCs were infected with Lenti-LacZ or Lenti-miRNA-21 at the indicated time points, BMP-2, Runx2, OCN, OPN, HIF-1α, and VEGF mRNA expression levels were detected by qRT-PCRBack to article page
