Cell Culture
The mouse Neuro2a cells were purchased from American Type Culture Collection. These cells were cultured in Dulbecco’s Modified Eagle’s Medium (DMEM; HyClone) supplemented with 4 mM L-glutamine, 4.5 g/L glucose, 1.5 g/L sodium bicarbonate, 1 mM sodium pyruvate, 1% penicillin/streptomycin (GIBCO) and 10% fetal bovine serum (FBS; Gibco) Isolation and expansion of mouse mesenchymal stem cells (mouse MSCs)
Mouse MSCs were isolated from the bone marrow of BALB/cA (6-8 weeks), which were purchased from National Laboratory Animal Centre, Mahidol University. Under sterile conditions, both ends of the long bones from femurs and tibias were cut with scissors, so the bone marrow cells were flushed out with DMEM using a syringe with a 21-to 25-gauge needle, followed by several times gentle pipetting. The aspirate is fractioned on a density gradient solution often Percoll or Ficoll (see appendix A) to eliminate some unwanted cell types and debris. The cells in the upper low-density fraction were then plated and enriched using standard cell culture techniques.
After cell seeding for 7-10 days mouse MSCs were selected by plastic adhesion, required the elimination of non-adherent haematopoietic cells by replacing the medium, DMEM/high glucose (Hyclone) supplemented with 20% FBS (HyClone), 2 mM L-glutamine (GIBCO), 1% penicillin/streptomycin (GIBCO) and 103 unit of mouse leukemia inhibition factor (LIF; R&D)
