Figure 5From: High risk HPV types 18 and 16 are potent modulators of oral squamous cell carcinoma phenotypes in vitroCAL27 morphology was altered by the presence of HPV. CAL27 cells (A) were plated in 96-well plates and allowed to proliferation with 10% FBS for three days. (B) HPV16-, (C) HPV18- and (D) HPV16/18-transfected cells increased in absolute number, confluence, and extent of cell spreading than non-transfected or mock-transfected cells (data not shown) under these conditions.Back to article page
