Immune cell mobilization and emergency hematopoiesis induced with lipopolysaccharide (LPS) injection. (A). Tg(mpeg:H2B-GFP) fish were crossed with Tg(mpx:mCherry) label macrophages (green) and neutrophils (red). The quantification of neutrophil (B) and macrophage (C) numbers and representative images (D) in the caudal hematopoietic tissue (CHT) (orange box) after PBS or LPS injection. Images representative of three independent experiments were shown (n = 20). Scale bar: 200 µm. (E,F) mRNA level of lyzC (E) and mfap4 (F) in the whole larvae injected with PBS or LPS. Results were normalized with ef1α and are presented as means ± SD (D) (n = 3 independent experiments with over 20 larvae each/experiment). *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, Mann–Whitney test. (G,H) mRNA level of csf3 and csf1 in whole larvae injected with PBS or LPS at 8 hpi (G) and 24 hpi (H). Results were normalized with ef1α and are presented as means ± SD (n = 3 biological repeats with 20 larvae in each group). *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, Mann–Whitney test.
