Fig. 6From: The effect of FK506 (tacrolimus) loaded with collagen membrane and fibrin glue on promotion of nerve regeneration in a rat sciatic nerve traction injury modelSciatic nerve segments. All tissues were harvested with a length of 10 mm, and the proximal area was marked with black ink. A Nerve segments of group A at 2 weeks. B Nerve segments of group A at 4 weeks. C Nerve segments of group B at 2 weeks. D Nerve segments of group B at 4 weeks. E Nerve segments of group C at 2 weeks. F Nerve segments of group C at 4 weeks. The collagen membrane is demonstrated to be maintained at both periods (circle) in panels C and FBack to article page
