Fig. 1

The distribution pattern of actinotrichia in zebrafish fin. (A) Phase contrast image of the median fin fold in larva at 3?days post-fertilization (dpf). Actinotrichia are radially distributed throughout the whole fin. (B) Magnified view of the box region in (A). (C) Distal tip of the adult caudal fin. Actinotrichia radially extend from the edge of each fin-ray to distal fin tip. White dot lines in (A and C) indicate actinotrichia orientation. (D) Confocal image of the actinotrichia isolated from larval fin. (E) Schematic diagram of the transverse section at the very tip of fin modified from Dane and Tucker (1985) and Wood and Thorogood (1987). Actinotrichia are located inside the epidermis constituted by two epidermal cell layers. Scale bar is 100?μm in (A–C) and 50?μm in (D).
