Figure 2

Photo micrograph showing immunohistochemical expression. (a) Membranous expression of PD-L1 in epithelial tumour cells present in the invasive front of oral squamous cell carcinoma (400×) (black arrow heads). (b) Membranous expression of PD-L1 in tumour associated fibroblast cells present in the invasive front of oral squamous cell carcinoma (400×) (black arrow heads). (c) Membranous expression of PD-1 in tumour- infiltrating lymphocytes (TILs) present in the invasive front of oral squamous cell carcinoma (400×) (black arrow heads). (d) Membranous expression of PD-L1 in dysplastic basal epithelial cells of oral leukoplakia (400×) (black arrow heads). (e) Membranous expression of PD-L1 in tumour associated fibroblast cells present subepithelial stroma of oral leukoplakia (400×) (black arrow heads). (f) Membranous expression of PD-1 infiltrating lymphocytes present in subepithelial stroma of oral leukoplakia (400×) (black arrow heads).
