We are having some problems culturing OPCs from the C57BL6 strain compared to the CD1 one. The protocol is as usual: we obtain OPCs from P0s mice brains, culture them in flasks in a mixed culture with DMEM supplemented with serum (FBS), shake them overnight and then seeded in a P96 plate. Does anybody have any clue about different media, serums, time of shaking? Thank you in advance.
