Implantation of HAP stem-cell hair-sphere-containing PVDF-membrane cylinders to C57BL/6J mice rejoined severed sciatic nerves. H&E staining of the severed part of sciatic nerve in implanted mice (A). Immunostained images of paraffin sections, 8 weeks after implantation of HAP stem-cells hair-sphere-containing PVDF-membrane cylinders between the severed sciatic nerve fragments, showed that the HAP stem cells differentiated into neurons (B), and glial cells (C). Right panels = high-magnifications of white boxes, individually. Bar = 100 µm.
