Characterization of proteomic profiles of hPDLSCs during osteogenic differentiation. a Overall profiles of proteins at four time points during osteogenesis of PDLSCs. b Pairwise correlation analyses of samples. The results are presented in the form of correlation matrixes. One matrix represents the overall protein expression of one sample. The colour of the square indicates the magnitude of the correlation, and the colour bar refers to the correlation coefficient. The number inside the square indicates the exact correlation coefficient between any two time points. c The number of DEPs across time points. The red sections of the bar indicate upregulated proteins, and the blue sections of the bar indicate downregulated proteins
