Marker expression in the surgical safety margin of LGD, HGD and T1 OSCC.

(a) Cell surface expression of E-cadherin, EMP1, 5T4 and N-cadherin in the surgical safety margins of LGD, HGD and T1 OSCC biopsies. (b) Marker expression in LGD, HGD and T1 OSCC surgical safety margins compared to normal tissue. (c) Marker expression in LGD, HGD and T1 OSCC surgical safety margins compared to their respective biopsy samples. (d) Statistical significance of low-grade dysplasia (LGD), high-grade dysplasia (HGD) and T1 OSCC when using healthy oral epithelium (NT), fibroepithelial polyp or the respective surgical margins as a healthy control. Grey boxes show statistically significant results.
