AQP1 and cervical carcinoma: AQP1 was predominantly localized to the microvascular endothelial cells in the stroma of mild cervicitis, CIN 2-3 and cervical carcinoma (Figure S1A, Figure S2), and the expression of AQP1 was significantly higher in cervical carcinoma than CIN2-3 and mild cervicitis (Figure S4A).
