Application of Amniotic Extracellular Matrix Nerve Conduit with Biological Material in the Peripheral Nerve Defect in vivo

摘要

Objective: To evaluate the peripheral nerve regeneration using a nerve conduit of amniotic extracellular matrix (AECM). Methods: 5 mm gap in the rabbit facial nerve was repaired with AECM conduit or with a silica gel conduit. After 7 days, 1 month and 3 months, the medullated nerve fibers and neural conductive velocity were determined. Results: On the 7th day, no neural regeneration was observed. But the neoformative neural fibers across AECM and silica gel were seen in the following 3 months, while the number and conductive velocity of medullated nerve fibers varied significantly at the different time points. Conclusion: AECM could repair the peripheral nerve defect.
