Spint1a deficiency is required at cell autonomous and non-autonomous levels to enhance SKCM cell dissemination in a zebrafish larval allotrasplantation model. Analysis of dissemination of control and Spint1a-deficient SKCM allotransplants in wild type larvae (a-d) and SKCM allotransplants in wild type and Spint1a-deficient larvae (e-h). a and e Experimental design. b and f Representative images (overlay of bright field and red channels) of SKCM invasion at 5 dpi. Bars: 500 μm. c and g Percentage of invaded larvae for both tumor genotypes. Each dot represents a single tumor and the mean ± SEM is also shown. **p < 0.01, ***p < 0.0001 according to unpaired Student t test. d and h Number of tumor foci per larva. ***p < 0.0001 according to Chi-square Tests
