Schwann Cells Overexpressing FGF-2 Alone or Combined with Manual Stimulation Do Not Promote Functional Recovery after Facial Nerve Injury
Figure 3
Myotopic organization of the facial nucleus and collateral axonal branching as estimated by the pattern of retrograde labeling. In intact animals, simultaneous application of DiI (red), FG (yellow), and FB (blue) to the zygomatic, buccal and mandibular nerve branches, respectively, labels distinct subnuclei with no overlap (a), (b). Two months after entubulation with collagen or collagen plus SC the myotopic organization is lost irrespective whether the animals received MS (c), (d).
