Neuropeptides play an important role in the regional regulation of blood flow and hormone secretion. Few studies report the presence of peptides in the human placenta. Our experiment evaluates neuropeptides in the human placenta using immunocytochemical techniques. Representative tissue sections from full-term placentae were fixed immediately after delivery and processed into paraffin sections or frozen. They were treated with multiple immunofluorescence, streptavidin-biotin-peroxidase complex and immunogold-silver staining techniques in combination with well-established monoclonal and polyclonal antibodies, using appropriate absorption controls to ensure the validity of the staining. Vasoactive intestinal polypeptide (VIP), calcitonin gene-related peptide (CGRP), neuropeptide tyrosine (NPY), galanin, somatostatin, met-enkephaline, helodermin and substance P-like immunoreactivities were demonstrated within decidual cells. Endothelin-1 was found in both trophoblasts and endothelial cells. Peptide immunoreactivities in the human placenta especially at the decidual interface between mother and fetus supports a role for the diffuse neuroendocrine system (DNES) in the regulation of placental blood flow critical for fetal growth and development.
