AT7519 and CDK9 morpholino knockdown has no effect on macrophage accumulation post-injury.

Tg(MPEG1:mCherry) zebrafish underwent tailfin transection and were treated with DMSO (control) or AT7519 at 4 hpi. (a) Example images of DMSO [i] and AT7519 [ii] – treated animals at 24 hpi are shown with cumulative data in (b). ≥22 fish per group over 3 independent experiments. Newly laid Tg(MPEG1:mCherry) zebrafish eggs were also injected with a CDK9 splice-blocking morpholino or mismatched control sequence, then raised to 3 dpf. (c) The embryo tailfin was transected and the fish imaged at various time points with example images shown at 24 hpi for morpholino [i] and control [ii] fish and cumulative data shown in (d). n ≥ 20 fish from 3 independent experiments. Data shown as ±S.E.M. *p < 0.05, n/s: not significant, assessed by two-way ANOVA followed by post-hoc Newman Keuls test.
