Effect of human amniotic epithelial cells transplantation on the pathological morphology of the injured brachial plexus in rabbits (hematoxylineosin staining, × 400).

(A) In the control group, the rabbit brachial plexus nerve fibers were arranged in neat rows. (B) At 24 weeks after brachial plexus injury in the injury group, the brachial plexus myelin appeared fractured. (C) At 24 weeks after transplantation of human amniotic epithelial cells, the majority of the connective tissue had formed an endoneurium at the surface of the brachial plexus nerve fibers and the endoneurium encased the myelin sheath. Arrows indicate the myelin sheath.
