Distribution and ontogeny of VIP-like immunoreactivity in the gastro-entero-pancreatic system of a cartilaginous fish Scyliorhinus stellaris

The presence, distribution and development of vasoactive intestinal polypeptide (VIP)-like immunoreactivity in the gastro-entero-pancreatic system of a cartilaginous fish Scyliorhinus stellaris (L.) was investigated by immunohistochemical methods utilizing mammalian VIP antisera. In the gut VIP-like immunoreactivity was observed in both nerves and endocrine… CONTINUE READING
