Figure 13From: The effect of epiregulin on epidermal growth factor receptor expression and proliferation of oral squamous cell carcinoma cell linesDensity of EGFR and ErbB4 receptors in the H103 cell line. The density of EGFR receptors treated for A 24 hours and B 48 hours, and the density of ErbB4 receptors treated for C 24 hours and D 48 hours. *Represents significant reduction in density of EGFR receptors (student t-test, p-value = 0.049).Back to article page
