Distal to the graft, the myelinated fiber density was also significantly higher in AG group (27,293.08 ± 195.8 axons/mm2) compared to DC-RA (14,337.13 ± 1324.54 axons/mm2, **p < 0.01) and DC-HX (2289.29 ± 513.73 axons/ ­mm2, #p < 0.01 vs DC-RA and ****p < 0.0001). All animals showed regeneration in the middle of the grafts. Dis- tal to the nerve graft, all animals from AG and DC-RA had myelinated axons, whereas only 3/6 animals of the DC-HX showed positive results (Fig. 4).” The original article can be found online at https://​doi.​org/​10.​1007/​ s00441-​022-​03682-1. * Esther Udina esther.udina@uab.cat 1 Department of Cell Biology, Physiology and Immunology, Institute of Neuroscience, Universitat Autònoma de Barcelona, and CIBERNED, ISCIII, Bellaterra 08913, Spain 2 Barcelona Tissue Bank, Banc de Sang I Teixits (BST), Barcelona, Spain 3 Biomedical Research Institute (IIB-Sant Pau; SGR1113), Barcelona, Spain 13 Vol.:(0123456789) 612 Cell and Tissue Research (2023) 391:611–612 Fig. 4  Histological evaluation of the regenerative potential of the taken at × 1000 magnification; scale bar 10 μm.
