Fig. 4 Blood flow measurements in live zebrafish embryos. A: Confocal image of the dorsal aorta and cardinal vein, 3 days postfertilization (dpf) AB, lateral view. B: A typical FCS flow measurement in the cardinal vein, showing both experimental curve (red) and fitting curve (black). At the bottom are the residuals of the fit. Experimental curves are fitted with a two flow model representing systolic and diastolic flow. C,D: Blood flow velocity profiles of systolic and diastolic flow, respectively. Results show measurements taken in the dorsal aorta (black) and cardinal vein (red).
