E18 Rat fetal bronchiolar neuroepithelial bodies (NEBs) marked with different peptides. A, B, and D are perfectly consecutive sections showing the same group of cells (arrows) immunostained for calcitonin gene-related peptide (CGRP) (A), proadrenomedullin N-terminal 20 peptide (PAMP) (B), and adrenomedullin (AM) (D). C, A fetal bronchiolar NEB immunostained for peptidylglycine alpha-amidating monooxygenase (PAM). Magnification, ×1250.
