Mean number of gad1b + gad2 (GAD), slc6a5, pax2a, lbx1a, evx1 + evx2 (evx) or Tg(evx1:EGFP) ^SU1 -expressing cells in the spinal cord region adjacent to somites 6–10 in 48 h embryos. SEM is the standard error of the mean. n is the number of embryos analyzed for each data set. p value is from a student’s paired t-test comparing WT and lmx1bb mutant embryos
