1. Cell Culture

[0196]1.1: Commercially Available Rat Primary Schwann Cells

[0197]Vials of rat Schwann cells (SC) primary culture (Sciencell #R1700) are defrost and seeded at the density of 10,000 cells / cm2 in “Sciencell Schwann cell medium” (basal medium from Sciencell #R1701) in poly-L-lysine pre-coated 75 cm2 flasks. The culture medium is composed of basal medium, 5% Fetal Bovine Serum (3H-Biomedical AB #1701-0025), 1% Schwann cell growth supplement (3H Biomedical AB #1701-1752), 1% Gentamicin (Sigma #G1397) and 10 μM of Forskolin (Sigma #F6886) to promote their proliferation.

[0198]After reaching confluency (4 to 10 days depending on cell batch), Schwann cells are purified by gentle agitation or by thy1.1 immunopanning that allow SC isolation from adherent fibroblasts, to produce cultures that are at least 95% pure. SC are then counted (Tryptan blue method) and seeded in poly-L-lysine pre-coated 75 cm2 flask in the same SC medium. At confluency, cells are rinsed, trypsinized (tryps...
