Fig. 1From: Association of HLA-G 3′ UTR polymorphism and expression with the progression of cervical lesions in human papillomavirus 18 infectionsImmunohistochemical staining of HLA-G expression in cervical lesions. (a) normal cervical tissue. The arrow refer to HPV hollowed out cells; (b) CIN1 lesion. The arrow refer to basal cells of the epithelium; (c) CIN2 lesion; (d) CIN3 lesion. Squamous cell abnormalities involving glands; (e) Adenocarcinoma. HLA-G protein is diffusely expressed in cytoplasm and membrane. Positive for HLA-G expression increased from CIN1 to CIN2/3 lesions and was highest in ADC lesionsBack to article page
