Easily applicable techniques are presented to obtain high numbers of enriched canine Schwann cells (cSC) in a short time-window. The potential of adult SC for tissue engineering of peripheral nerves and ex vivo gene therapy is obvious from physiological events taking place after peripheral nerve transection [Haastert, K., Grothe, C., 2007. Gene therapy in peripheral nerve reconstruction approaches. Curr. Gene Ther. 7, 221-228]. The presented techniques were modified from a protocol for cultivation and expansion of adult cSC by others [Pauls, J., Nolte, C., Forterre, F., Brunnberg, L., 2004. Cultivation and expansion of canine Schwann cells using reexplantation. Berl. Munch. Tierarztl. Wochenschr. 117, 341-352] and own experiences in rodent and human SC cultivation and transfection [Haastert, K., Mauritz, C., Chaturvedi, S., Grothe, C., 2007. Human and rat adult Schwann cell cultures: fast and efficient enrichment and highly effective non-viral transfection protocol. Nat. Protoc. 2, 99-104]. A purity of about 80% cSC achieved by immunopanning techniques and selective culture conditions is 2.5 fold higher as previously reported (Pauls et al., 2004). Additionally, highly enriched cSC populations are available in 3-4 weeks, only half the time period reported previously (Pauls et al., 2004). Furthermore, electroporation and genetic modification of cSC is reported for the first time.
