LESCs cultured following the gold standard or explants culture methodologies with FBS or human HS and s-PRGF sera: (A) Phenotype of cell cultures; (B) Percentage of cells corresponding to each cell size; (C) Cell growth rate represented as the number of cell duplications per day. * Indicates significant differences between the gold standard culture and the indicated treatment. (* p < 0.05). Scale bar in phase-contrast microscopy images, 100 micrometers. LESCs: limbal epithelial stem/progenitor cells; FBS: fetal bovine serum; HS: human serum; s-PRGF: serum derived from plasma rich in growth factors.
