Expression level and tissue distribution of S100P protein. Immunofluorescence staining of S100P in human endometrium at PE (E, F and G), ESE (I, J and K), MSE (M, N and O), and LSE (Q, R and S) are shown; PBS substituted for the primary antibody was used as the negative control (A, B and C); Hoechst was used for nuclei staining (blue) (B, F, J, N and R); S100P fluorescent images (red) (A, E, I, M and O), merged images (C, G, K, O and S), and hematoxylin and eosin (HE) staining (D, H, L, P and T) are shown; higher magnification view of the selected areas in MSE staining (M, N and O) are shown in the lower right corner; scale bars represent 100um.
