Fig. 1 Modulation of Vascular Flow Affects HSC Formation in Zebrafish

(A–M) Effect of blood flow modifiers on runx1/cmyb+ HSC formation. Zebrafish were exposed to chemicals (10 μM) from 10 somites–36 hpf and subjected to runx1/cmyb in situ hybridization. Photomicrographs were taken with Nomarski optics at 40x magnification. Representative examples from after drug treatment are shown.

(L) Effect of todralazine (10 μM; 67 inc/84).

(M) Effect of drug treatment on runx1 expression, quantified by qPCR (mean ± SD).

(N) Effect of drug treatment on the diameter of the dorsal aorta in vivo. Transgenic fli:GFP fish were treated with chemicals and imaged by confocal microscopy at 36 hpf; all treatments were statistically significant from the control (mean ± SD, ANOVA, p < 0.001).
