Perineurial fibroblasts are of mesenchymal origin and form the perineurium. The perineurium plays an important role in maintaining the integrity of the internal peripheral nerve environment by creating a physical barrier that, under physiologic condition, limits the entry of biologically active proteins, infectious agents, and blood-borne cells into the nerve bundles. The perineurial fibroblasts are characterized by distinct ultrastructural features, including nonbranching thin cytoplasmic processes coated by an external lamina and joined at their ends by a tight junction, few organelles, actin and vimentin filaments, and numerous pinocytotic vesicles. Perineurial fibroblasts are initially recruited from the surrounding mesenchyme to form a loose, permeable sheath around axons and Schwann cells, where they are separated by the extracellular matrix.
