Analysis of myeloid cell populations in gcsfr morphants. (A-L) WISH analysis of embryos injected with scramMo or gcsfrMo1 at various time points using antisense probes to specific myeloid genes, as indicated. (M-S) The total number of cells positive for the indicated myeloid markers from embryos injected with either scramMo or gcsfrMo1 was counted, showing mean (dashed red line), 95% CI (solid red lines), and level of statistical significance (*P < .05; **P < .01).
