At postnatal day one of life (P1), pups (
aldh5a1+/+ and aldh5a1−/−) were sacrificed, and the brain gently eviscerated into
Hibernate media supplemented with
penicillin/streptomycin and
B27 medium (Thermo Fisher, Waltham, MA, USA). The cortex and hippocampal regions were dissociated with
Versene (Thermo Fisher) in media (37°C). Cells were maintained in complete medium consisting of Neurobasal
® A Medium (Thermo Fisher) supplemented with B-27
® Serum-Free Supplement,
GlutaMAX™ (Gibco, Thermo Fisher),
antibiotic-antimycotic solution (Gibco, Thermo Fisher), FGF-basic (recombinant human (bFGF)), and
EGF (recombinant human epidermal growth factor; Millipore, Darmstadt, Germany). Cells were expanded in 35-mm and 100-mm dishes coated with
poly-L-ornithine (Sigma, St. Louis, MO). Confluent cells were passaged using
Versene. Tail biopsies from P1 pups were obtained and genotype was determined as described (Hogema et al 2001 (
link)). The neuronal status of these cells was confirmed using Nissl staining, as well as immunohistochemistry for Nestin and Sox2.
