Abstract

The regulation of the vasculature in the skin is a complex process involving both perivascular nerves and local endothelial-mediated control. In this study, the perivascular innervation in the mystacial pad ofthe rat was characterized based upon immunochemical and lectin binding characteristics and distribution. All of the innervation labeled with anti-protein gene product 9.5 (PGP 9.5), which was used in double- and triple-labeling combinations with the Griffonia simplicifolia lectin (GSA) and antibodies against a variety of neuropeptides, enzymes, and structural proteins. GSA histofluorescence revealed an intricate microvasculature within the rows of tactile vibrissae, which form a natural grid to standardize analyses. Specific features of the vascular organization were confirmed by scanning electron microscopy. Each interval between adjacent vibrissae contained a predictably organized microvascular module composed of separate arterial channels and capillary networks for each of several different structures: papillary muscles, facial muscles, the interior of vibrissal follicle-sinus complexes, vibrissal papillae, and the upper dermis of the intervibrissal fur. Each module was innervated by at least tyro sets of sensory, at least two sets of sympathetic, and at least one possible set of parasympathetic. These sets not only differed in their biochemical characteristics, but also in their relative position within the arterial walls and their distribution among the microvasculature to the various structures. As such, the microvasculature to each type of structure had a particular combination of innervation, suggesting that separate neuronal mechanisms may be involved in regulating the blood flow to different types of targets even within the confines of a small territory of tissue.
