Methylcobalamin Facilitates Collateral Sprouting of Donor Axons and Innervation of Recipient Muscle in End-to-Side Neurorrhaphy in Rats
Figure 5
Cross sections of the distal segments of the ESN repaired nerves.
Representative micrographs of animals 1 (upper row), 3 (middle row) and 6 months (lower row) following ESN were illustrated. Each micrograph was taken from a toluidine blue-stained, semithin cross section of the recipient nerve 1 mm distal to the neurorrhaphy site. The nerve was embedded in plastic. Micrographs from PBS, MeB12 and MeB12+PTN-treated ESN animals are illustrated. Scale bar = 25 µm for all.
