“…Methods including the use of neurotrophic factors (Meyer, Matsuoka, Wetmore, Olson, & Thoenen, 1992;Sendtner, Kreutzberg, & Thoenen, 1990), supportive cell grafts (e.g., SCs; Seggio, Narayanaswamy, Roysam, & Thompson, 2010) or stem cells (Zhang et al, 2010), autografts (den Dunnen & Meek, 2001), and artificial nerve conduits (Nectow, Marra, & Kaplan, 2012;Xu et al, 2003) have been shown to influence axon outgrowth and myelination both in vivo and in vitro.
