EGFR and neoplasm: Cluster S at parental stage has enhanced locomotion, cell adhesion, cell motility, and wound healing, as well as signaling pathways related to tumor migration (PI3K‐Akt,[25] ErbB,[26] and p53 signaling),[22] interaction (ECM‐receptor interaction, CAMs signaling),[21] and immunity (leukocyte transendothelial migration; Figure 3D).
