There are two types of interrenal cells identified (1) The noradrenaline type, which contain heterogeneous vesicles with electron-dense granules located asymmetrically within the vesicular membrane. (2) The adrenaline type, in which the vesicles are smaller and contain homogenous electron-lucent granules that are separated from the vesicular membrane by a visible -- halo http://dev.biologists.org/content/130/10/2107.full GAID:1227 interrenal BTO:0000808 UBERON:0006856 interrenal tissue TAO:0001345 interrenal bodies An epithelial structure consisting of steroid producing cells interposed with chromaffin cells embedded within the head kidney. The interrenal gland is thought to be the equivalent of the mammalian adrenal cortex in zebrafish. Hsu et al. 2003.[TAO] ZFA:0001345 Structures in fishes homologous to the cortical tissue of the mammalian adrenal gland; they are in close proximity to or imbedded in the head kidney. interrenal gland MESH:D007401 All craniates have groups of cells homologous to the mammalian adrenocortical and chromaffin tissues, but they are scattered in and near the kidneys in fishes. (...) The cortical and chromaffin tissues come together to form adrenal glands in tetrapods.[well established][VHOG] interrenal body interrenal primordium adrenal/interrenal gland head kidney structure with developmental contribution from neural crest
