Fig. S9 Delays in proto-neuromast formation and deposition upon fgf10 knockdown. (A) Patterns of proto-neuromast deposition at 48 hpf in embryos injected with 1, 2, 4 ng of fgf10-MO. White arrows indicate deposited neuromasts and yellow arrowheads indicate the end of the PLLp migration. (B) Patterns of neuromast deposition in individual embryos. Individual embryos are represented on separate lines in an order determined by the relative position of L2. (C) Average position of each deposited neuromast in embryos injected with 2 ng fgf10-MO. x-axis represents deposited neuromasts, L1 to L6, and y-axis represents distance of each deposited neuromast relative to the distance from the otic vesicle to the tip of the tail. (D) Distance of two adjacent proto-neuromasts deposited in embryos injected with 2 ng fgf10-MO. Data are presented as the average ± s.d. Statistical significance of the differences between each pair of groups was determined by Student’s t-test. **P<0.01, ***P<0.001; ns, not significant.
