Fig. 2
hspd1 expression is induced after injury. (a) hspd1 expression is induced in lateral line neuromasts by CuSO4-mediated hair cell ablation. Pictures are of embryos collected 5?h post-copper or control treatment, the time point with the largest expression differences. Arrows indicate the induced expression in lateral line neuromasts. The bottom panel is a higher magnification to more clearly show the neuromast-specific expression only seen in a CuSO4-treated embryo. (b) Histological sectioning shows the induced hspd1 expression in a cross-section of a neuromast localised in the trunk. (c) hspd1 expression is induced by caudal fin amputation. Pictures are of embryos collected at 17?h post amputation (or an undissected control), which was the peak of hspd1 expression. Bars = 200??m in a and c, 20??m in b.
