Analysis of (a) total granule area, (b) granule areal density, (c) granule diameter, (d) rough endoplasmic reticulum (rER) areal density, and (e) Golgi apparatus dilation in corticotrophs from wild-type (WT), heterozygous (HT) and ANXA1-null mice. Filled bars, male; open bars, female corticotrophs. Data are mean ± SEM (n = 4 for all groups). *P < 0.05 versus wild-type of the same gender.
