Cholinergic medullary epithelial cells are not innervated. a Calcitonin gene-related peptide (CGRP)-immunoreactive varicose nerve fibre (arrows) next to a medullary blood vessel (V). However, the ChAT-eGFP-positive cell with an elongated process (arrowhead) is not approached by a nerve fibre. b Non-innervated ChAT-eGFP-positive cell (arrowhead) distant from a medullary protein gene product 9.5 (PGP9.5)-immunoreactive varicose nerve fibre (arrows). a Female aged 25 weeks. b Female aged 17 weeks.
