Stimulation of tumorigenic liver growth by tumor-infiltrated neutrophils.
TO(Myc) and Tg(mpx:EGFP) double transgenic larvae were used for norpholino knockdown of Gcsfr to inhibit neutrophil differentiation. Morpholino oligonucleotides were injected into the embryos at 1-2-cell stage. (A-D) Images of the double transgenic larvae after injection of either MO(control) (A,C) or MO(gcsfr) (B,D). These injected embryos were either treated with Dox (C,D) or without Dox from 4 dpf to 7 dpf (A,B). The liver areas are circled. The original magnification was 20x. (E) Neutrophil counts in the liver. (F) Neutrophil density in the liver under different conditions. (G) Quantification of 2D liver size. The quantitative data were based on 5 samples per concentration group. Data are represented as mean ± SD. Asterisks indicate significant difference with P-value < 0.05 by unpaired t-test statistical analysis. Scale bars = 100 µm.
