FIGURE 7

Histological profile of muscles innervated by repaired peripheral nerves. Figures show the histological pattern of the tibialis anterior and the gastrocnemius muscles stained with picrosirius (upper images for each) and Masson trichrome (lower images for each) methods of each experimental condition (Auto, Nano, and Coll-Nano) and native control (CTR). Observe that the histological pattern of Auto groups was comparable to the native control whereas different degrees of atrophy and even fibrosis can be observed in Nano and especially Coll-Nano groups. Scale bar = 100 μm in each.
