Data from E14.5 and E18.5 cohorts were analysed separately by a linear mixed model with maternal STZ and insulin treatment and offspring sex as independent variables, weighted for litter. Values are mean±SEM. E14.5: (n) = control (n = 5 litters comprising 41 embryos), STZ-treated (n = 5 litters comprising 33 embryos). E18.5: (n) = control (n = 11 litters comprising 72 embryos), STZ (n = 10 litters comprising 41 embryos), STZ+Insulin (n = 5 litters comprising 25 embryos).
