Quantitative PCR results for oct4, sox2 and nanog markers on day 0 (A) cultured limbal, conjunctival and oral biopsies. Results were calibrated with β-actin. All the experiments were performed in triplicate using 6 samples per group (limbal, conjunctival and oral). Representative FACS plots of day 14 cultured limbal conjunctival and oral mucosal epithelial cells stained with antibodies against OCT4, SOX2 and NANOG (B).
