The hybrid clones exhibited variable tumorigenicity. SCCVII/SF-GFP (SCC), hybrid clone D2, and hybrid clone D3 cells were grown in the rear flank of C3H or NSG mice. Tumors were harvested on day 21 (C3H) or day 16 (NSG). (A) Top panel: Individual-value plot of tumor weight (C3H mice). Lower panel: Gross photos of the tumors. The injection site in one mouse receiving the D2 cells could not be identified, and the tissue was not included in the picture. (B) Top panel: Individual-value plot of tumor weight (NSG mice). Lower panel: Gross pictures of the tumors. *p ≤ 0.05, **p ≤ 0.01
