[Retracted] The Use of a Hypoallergenic Dermal Matrix for Wrapping in Peripheral Nerve Lesions Regeneration: Functional and Quantitative Morphological Analysis in an Experimental Animal Model

Figure 4

Representative high-resolution (40x) light microscopy images of toluidine-blue stained semithin transverse sections of regenerated median nerve repaired with end-to-end nerve suture, with (Group A) or without (Group B) a conduit of collagen matrix (OrACELL®) wrapped around the suture into a protective sleeve. Seven months after surgery, in both groups, regrowing myelinated fibers (F) with well-organized myelin sheaths (M) are detected. BAR=20μm.
