Morphology and proliferation of the MSCs obtained. (a) Representative photos of the cell morphology observed in each sample are shown (100x, scale bar = 100 μm), along with representative images of cells with a spindle-shaped or large morphology (400x, scale bar = 100 μm). (b) The means ± SEM of the percentage of spindle-shaped cells and large cells in the MSC cultures. ^∗Statistically significant differences between NLE-MSCs vs. HD-, NLD-, LD-, HE-, and LE-MSCs. ^§Statistically significant differences between BM-MSCs vs. HD-, NLD-, LD-, HE-, and LE-MSCs. (c) Cell proliferation (fold change) was measured after 100,000 cells were cultured for 6 days. After culture, the cells were harvested and counted using trypan blue staining; the viability percentage in all cultures was greater than 98%. ^∗Statistically significant differences with p < 0.05. ^§Statistically significant differences with p < 0.05 between BM-MSCs vs. HD-, NLD-, LD-, and HE-MSCs.
