title: Vasoactive intestinal peptide regulation of nerve growth factor in the embryonic mouse.
abstract: Vasoactive intestinal peptide (VIP), a regulator of embryonic growth, increased the concentration of nerve growth factor (NGF)-like immunoreactivity in the conditioned medium of cultured explanted embryonic day (E) 9.5 neural tube preparations compared to control preparations. VIP treatment also induced an increase of NGF-like immunoreactivity (NGF-IR) within the neural tube preparation tissue. A 60 kDa isoform was the primary form of NGF detected. VIP is shown to be a regulator of NGF in the E9.5 embryonic mouse and stimulates the release of a high molecular weight isoform of NGF.
