mRNA expression profile of apoptotic markers, bcl2, bax, caspase 3 and caspase 9 genes of day 14 limbal, conjunctival and oral cultured cells (B). Results were normalized with β-actin. All the experiments were performed in triplicate using 6 samples per group (limbal, conjunctival and oral). Significance denoted, p *<0.05, **<0.01, ***<0.005.
