Fig. 7. Density and placement of actinotrichia at the tip of the fin in 3-week-old fish. (A, B) The actinotrichia of the fin tip in 3-wewk-old visualized with actinodin1-GFP (Kuroda et al., 2018). The fin-rays were visualized using Alizarin Red to set the starting point of transverse section. White dot lines in A and B indicate the positions of transverse sections in C, D, E, and F. (C, D) Transverse sections control (C) and col9a1c(-/-) (D). (E, F) Magnified images of white dashed boxes in C and D, respectively. The section interval was 40 ??m in C and 20 ??m in D. The same actinotrichia were chased from 1 to 6. (G, H) Schematic of actinotrichia arrangement in the fin deduced from the images of the sections. Scale bars: 20 ??m in A, B; 10 ??m in C, D; 5 ??m in E, F.
