Figure 4.
Cellular phenotype and dynamics inside recellularized pericardia. (A–C) Immunofluorescence staining showing expression of αSMA, PCNA, and YAP (all in green fluorescence) in conjunction with Vimentin (in red fluorescence) inside the recellularized pericardial tissue at day 3 and 21 of culturing. In each panel the lower micrographs show the magnification of the boxed insets in the higher photographs. (D) Quantification of total number of cells by DAPI-stained nuclei counting (upper bar graph), PCNA+ cells (middle bar graph) and cells with nuclear localized YAP (nYAP+ cells, low bar graph) at all the considered time points. Statistical analysis was performed with one-way ANOVA with Newman Keuls post-hoc; * indicates P < 0.05 (n = 3).
