Fig. 1 Fig. 1. shSK-E17T Ewing sarcoma zebrafish xenografts A) Zebrafish xenografted with GFP-expressing shSK-E17T Ewing sarcoma cells (green) imaged on a fluorescence microscope over consecutive days from 2 hpi to 3 dpi. B) Immunostaining for human Ki67 revealing proliferating tumor cells and C) for cleaved Caspase 3 demarcating apoptotic cells at different time points from 2 hpi to 3 dpi. (B, n: 2 hpi = 5, 1 dpi = 7, 2 dpi = 5, 3 dpi = 6); (C, n: 2 hpi = 6, 1 dpi = 8, 2 dpi = 5, 3 dpi = 7). Scale bars are 250 μm in A and 50 μm in B and C.
