The fine structure of dermal blood vessels of male Wistar rats was studied in paw regions. Electron microscopy revealed a well-developed plexus of fenestrated capillaries in papillary dermis and adjacent to skin appendages. Intravenously injected ferritin escaped from some of these capillaries. It is suggested that these blood vessels play a role in the exchange of substances at sites of high epithelical turnover.
