Effects of tissue-engineered nerve prepared using autologous platelet-rich plasma gel for suspension of Schwann cell-like cells in a poly(lactic-co-glycolic acid) nerve conduit for regenerating nerve fiber myelin sheath in rabbits with sciatic nerve injury (transmission electron microscopy, × 4 000).

Regenerating sciatic nerve fibers from the platelet-rich plasma group (A) demonstrated a thicker and well-arrayed myelin sheath compared with the fibrin group (B). Arrows highlight the myelin sheath.
