  • Title: The effect of extraction of the intrafascicular contents of peripheral nerve trunks on perineurial structure.
    Author: Thomas PK, Bhagat S.
    Journal: Acta Neuropathol; 1978 Aug 07; 43(1-2):135-41. PubMed ID: 676678.
    Abstract:
    The intrafascicular contents have been extracted from the tibial nerve of the rabbit through perineurial incisions. Within 6--8 days following this procedure, the perineurial cells separate from one another, become dissociated from their basement membranes and assume a fibroblast-like appearance. The intrafascicular space becomes populated with endoneurial fibroblasts. With the ingrowth of regenerating axons, bundles of axons and associated Schwann cells become surrounded by cells of fibroblastic appearance which undergo perineurial transformation resulting in the development of multiple small fascicles. The cells of the surrounding perineurium appear to reassume a lamellar organization and to reestablish contacts with each other with the formation of junctional complexes. It is therefore suggested that neural structures may be responsible for the development and maintenance of the structural organization of the perineurium.
