title: Relationships between mast cells and preterminal nerve fibers.
abstract: The observations demonstrate that mast cells do not only show intimate morphological associations to peripheral nerve fibers but also contact basement membranes of capillaries and cell surface coats of organ parenchyma cells. Interpreting these results as a neuro-hormonale feedback system mast cells might be regarded as both receptor organs and regulators of metabolism.
