Quantitative PCR results of hes1, hes3, hes5 and hey1 mRNA expression in day 0 cultured limbal, conjunctival and oral biopsies (A). mRNA expression of hes1, hes3, hes5 and hey1 in day 14 limbal conjunctival and oral cultures (B). Results were calibrated with β-actin. All the experiments were performed in triplicate using 6 samples per group (limbal, conjunctival and oral). Statistical significance denoted, p *<0.05, **<0.01, ***<0.005. To access the data, click or select the words “Appendix 4.”
