Reduction in PGC migration speed during development. (A) PGCs at the gonad region at 24-36 hpf. (B,C) PGC speed (B) and displacement (C) over 60 min (24-26 hpf: 8 embryos, 60 PGCs; 34-36 hpf: 12 embryos, 48 PGCs). (D) PGC clusters at the gonad and the head at 24-36 hpf. (E,F) PGC speed (E) and displacement (F) in ectopic clusters over 60 min (24-26 hpf: 11 embryos, 26 PGCs; 34-36 hpf: 10 embryos, 17 PGCs). (G,H) PGC speed (G) and displacement (H) at the gonad over 60 min (24-26 hpf: 12 embryos, 32 PGCs; 34-36 hpf: 11 embryos, 42 PGCs). Unpaired two-tailed t-test. Data are median ± error bars (IQR). Scale bars: 20 µm.
