Fig. 3: Morphology of the reinnervating nerve fibers.
From: Creation of a biological sensorimotor interface for bionic reconstruction
A cross-section of a nerve fiber bundle in the dermal graft. It contains many small- to medium-sized NF-positive nerve fibers (red), however, only some have a myelin sheath as visualized by the anti-MBP staining (green). (n = 12, biological replicates) B Two reinnervated muscle spindles (large arrows) within their respective capsules. They are accompanied by bundles of large, myelinated (S100, green) nerve fibers (NF, red) (*). These types of fibers can also be seen attached to the intrafusal fibers (small arrows), suggesting robust proprioceptive reinnervation. (n = 13, biological replicates) (NF neurofilament, MBP myelin basic protein).
