Tumorigenicity of cell lines in SCID mice. (A) Tumor size and (B) body weight of injected SCID mice were measured twice weekly. ETCC001 does not form tumor while the hTERT expressing ETCC008 form palpable tumors that were less than 30 mm3. (C) Histological images of the tumors performed at the end of the experiment show the epithelial cells arranged in densely packed solid pattern that were well differentiated with varying size and shape (H&E stained, 40X magnification).
