I have started isolating and culturing primary glial cells from pig. So far it has been working fine, but After certain passage of OPC my cells, as it looks like, not responding to differentiating media into Oligos, or somehow, during passaging it got already differentiated to Astrocytes.. I have been culturing OPC on plates coating with collagen 1 from bovine origin and basal neural media containing 1x Glutamax, 1X B27 and 1X N2 supplement plus PDGF AA (20ng/ml) and hFGF (20ng/ml).. Any suggestion will be highly appreciated..
Thanking you,
Best
