Ultrastructural identification of a new cell type--the N-cell as the source of neurotensin in the gut mucosa.

abstract：:A somatostatin-like substance is demonstrated by light microscopic immunohistochemistry (PAP-method) in perikarya and cell processes of the retina of adult and infant rats. These perikarya are identified according to their size, arrangement and distribution. Each of the first two neuronal orders (receptors, bipolar ce...
