GFM1 and neoplasm: Similar with the hypodermic yielded tumor masses, the weight of primary tumor masses of CD97/EGF1,2,5 kd group (0.6±0.14 g) were significantly lower as compared to SGC wt (2.8±0.26 g) and SGC-NS (2.6±0.28 g) groups on post operative days 42, which again suggested the tumor supporting effect of CD97 small isoform (Figure 3B).
