Extended Data Fig. 2: Extracellular current measurements from non-migratory to migratory stages.
From: Stretch-induced endogenous electric fields drive directed collective cell migration in vivo

a, Cartoon showing temporal vibrating probe measurements along the migratory path of the neural crest from non-migratory to migratory stages (st13, st15, st17, st20 and st22). Drawing also shows the positions where the measurements were taken from the neural fold to the flanking non-neural ectoderm. b, Results from vibrating probe current density measurements in the neural fold and flank non-neural ectoderm (as indicated). Dots represent mean and shade the standard errors. Two-tailed paired t-test (st13–20) or two-tailed Wilcoxon matched-pairs test (st22), **pst13 = 0.0017, **pst15 = 0.0042, *pst17 = 0.0339, ***pst20 = 0.0008, **pst22 = 0.0078, n = 35 embryos.
