Viability of corneal keratocytes cultured in two different media. A) serum-free medium (FD) supplemented with AH ranging from 0% to 3.125%; B) medium containing serum (FDS) supplemented with AH ranging from 0% to 3.125%; C) comparison of the cell viability between the FD and FDS supplemented with different concentrations of AH. Significant difference (p < 0.05) between the same medium was marked with (*) while (#) denotes significant difference (p < 0.05) between different media. Values were expressed as mean ± SEM, n = 6.
