TL;DR: Immunoreactive somatostatin (IRS) was measured in acid extracts of human gastrointestinal tissue and showed the IRS in the mucosa to be localised in endocrine-type cells, while in the muscle layer the IRS is present in nerve fibres and neurones of the myenteric plexus.

TL;DR: The presence and heterogeneity of bombesin-like immunoreactivity throughout the human gastrointestinal tract is demonstrated and it is shown for the first time that a proportion of this BLI closely resembles porcine GRP.
