Additional analyses of microridge development. (A) Box and violin plot of microridge length in periderm cells at the indicated stages of zebrafish development. For a weighted presentation of this data, see Fig. 1 B. ***, P < 0.001; Kruskal–Wallis test followed by Dunn’s test (n = 15,582 structures in 23 cells from 10 fish at 16 hpf; n = 5,096 structures in 40 cells from nine fish at 24 hpf; n = 4,572 structures in 40 cells from nine fish at 32 hpf; n = 1,309 structures in 19 cells from six fish at 48 hpf). (B) Dot and box plot of average microridge length per periderm cell at the indicated stages of zebrafish development. **, P < 0.01; ***, P < 0.001; Kruskal–Wallis test followed by Dunn’s test (n = 15,582 structures in 23 cells from 10 fish at 16 hpf; n = 5,096 structures in 40 cells from nine fish at 24 hpf; n = 4,572 structures in 40 cells from nine fish at 32 hpf; n = 1,309 structures in 19 cells from six fish at 48 hpf). (C) Scatter plot of average microridge length per cell versus apical cell area at the indicated stages of zebrafish development (n = 15,582 structures in 23 cells from 10 fish at 16 hpf; n = 5,096 structures in 40 cells from nine fish at 24 hpf; n = 4,572 structures in 40 cells from nine fish at 32 hpf; n = 1,309 structures in 19 cells from six fish at 48 hpf). For box plots, middle box line is the median, and lower and upper ends of boxes are 25th and 75th percentiles, respectively.
