Morphology of Schwann cell alignment along oriented electrospun poly(lactic-co-glycolic acid) (PLGA)/chitosan nanofibers.

(A) Morphology of oriented electrospun PLGA/chitosan nanofibers (scanning electron microscopy, scale bar: 1 μm). (B) Morphology of Schwann cells (arrow) cultured on the oriented electrospun PLGA/chitosan nanofibers (scanning electron microscopy, scale bar: 50 μm). (C) S-100 expression (arrow) in Schwann cells cultured on the oriented electrospun PLGA/chitosan nanofibers (scale bar: 50 μm).
