Fig. S3 Spatial expression of zebrafish hmgb1b. (A–C) At early developmental stages hmgb1b is ubiquitously expressed, and at tailbud stage it is particularly expressed at the midline (C, white arrowhead). (D and E) During somitogenesis it is still broadly expressed, with the exception of the notochord and somites (E, grey arrow). (F and G) At 24 hpf, hmgb1b expression is restricted to specific regions of the embryos, mainly in the CNS, but is also visible in the spinal cord (SC), in the lateral line primordium (F, blue arrow), in the intermediate cell mass (F, blue arrowhead) and in pectoral fin buds (G, asterisk). (H and I) At 2 dpf the detectable signal is in the rostral CNS, in the pronephric ducts (H, light blue arrow) and in pectoral fin buds (I, asterisk). All panels show whole-mount images. (A, C, D, G and I) Dorsal views; (B, E, F and H) lateral views, anterior to the left. All images are taken at 40× magnification.
