Fig. S4

Figure S4. Fate-mapping of neutrophils from CHT, related to Figure 5.

(A) Schematics of photoconversion. UV converts green fluorescent Dendra2 to red, allowing for fate-mapping.

(B) Photolabeled neutrophils responded to the wound in a control morphant, whereas in a Rac2 morphant, neutrophils did not migrate to the wound, but entered circulation. Locations of wounds were highlighted. Arrow, circulating neutrophil. Images are representative for 6 larvae from 2 separate experiments. Scale bar, 50 μm.

(C) Neutrophil in the CHT at 2dpf Rac2 morphants spontaneously entered circulation 18 h after photo-conversion. Still images from one movie representative for 9 zebrasfish (3 independent experiments) are shown. Location of blood vessel is highlighted. Arrow, circulating photoconverted neutrophils. Arrow head, a circulating non-photoconverted neutrophil. Scale bar, 30 μm.
