(A) RT-qPCR analysis demonstrated that expression of il6 and its receptor il6R are increased by CoCl2 exposure (*p<0.05, **p<0.01, one-tailed t-test, n≥3).
(B) Morpholino knockdown of il6 diminished the ability of CoCl2 to stimulate runx1;cmyb expression in the VDA over that seen in controls as determined by WISH analysis at 36hpf.
(C) Qualitative phenotypic distribution of embryos from panel 5B (n≥20/condition × 3 replicate clutches).
(D) FACS analysis confirmed that CoCl2 was unable to enhance the number of CD41+ HSPCs in the presence of il6 knockdown (*p<0.05, one-tailed t-test, n≥4).
(E) Injection of dnhif1a mRNA decreased runx1;cmyb expression in the VDA at 36hpf, which could be partially ameliorated by overexpression of il6.
(F) Qualitative phenotypic distribution of embryos from panel 5E (n≥20/condition × 3 replicate clutches.
