Fig. 2From: Identification of key genes and pathways of BMP-9-induced osteogenic differentiation of mesenchymal stem cells by integrated bioinformatics analysisThe volcano plot of differentially expressed genes. The abscissa is − log10 (P.Value) and the ordinates is logFC. The red dots stand for the up-expressed genes, green dots stand for down-expressed gene while the black dots represent genes not differentially expressedBack to article page
