Figure 7. Tumorigenicity of PEDF-SKOV3 cells on CAM model.
(A) Growth kinetic of PEDF-SKOV3 (grey) or CTRL-SKOV3-derived tumor (black). (B) Photographs (upper panel; magnification ×16.5) and Hemalun Eosin staining (middle panel; magnification ×100) of CTRL-SKOV3 and PEDF-SKOV3-derived tumors at EDD13.5. Enlargement of the black squares was presented in the lower panels (magnification ×400). Tumors are indicated by black arrows, and CAM and tumor vessels by white arrows.
