Cell proliferation was evaluated by cell counting and CCK-8 assay. A Cell growth curves of three groups, including culture dish, PLGA scaffold, and PLGA@PLL scaffold, were made according to cell counting. B Statistical analysis of cell proliferation according to CCK-8 assay (n = 6). C Cell growth curves of hUC-MSCs seeded on the culture dish, PLGA scaffold, and PLGA@PLL scaffold were made based on cell counting. D Statistical analysis of cell proliferation based on CCK-8 assay (n = 6). E Expression levels of the Ki67 and PCNA genes among the control and the scaffold groups were compared (n = 5). F Expression levels of the VCAM-1 and ICAM-1 genes among the control and the scaffold groups were compared (n = 5). The data were normalized to the internal control β-actin and are plotted. *indicates p < 0.05, **indicates p < 0.01, ***indicates p < 0.001, two-tailed t-test
