Mesenchymal to pericyte transition (MPT) by different tumor cell-derived conditioned media (TCM). A-B. Representative images of MPT of 10T1/2 mesenchymal cells grown in regular media or different tumor cell-derived conditioned media for 24 h or 72 h. Cells are immuno-stained with pericyte-specific marker α-SMA, X200. C. Imuno-Western blots of α-SMA and desmin in 10T1/2 cells grown in different TCM for 24 h. The bar graphs represent the quantitative analysis from three different experiments. P-values were determined by unpaired student's-test. *p < 0.01 vs control (RM).
