| Collection Summary: | Hypothalamic primary neuronal cell culture Eight to ten neonatal (0 days old) pubs from either control or Ucp2PomcKO mice derived from homozygous Cre-positive parents were used for hypothalamic primary neuronal cell culture. In brief, we carefully removed the brain's hypothalamus and placed it onto a small culture dish containing a small volume of Hibernate-A Medium (Cat# A1247501, Thermo Fisher Scientific). After digestion, the tissues dissociated to single cells with 6 mL of Hibernate-A Medium containing 2.5 % of Trypsin-EDTA for 15 minutes at 37℃. Suspended cells were filtered (40 μm) and centrifuged for 5 min at 1000 rpm. The pellet was re-suspended and plated on XF96 cell culture microplates (Cat# 101085-004, Agilent Technologies) coated with poly-D-lysine (Cat# P6407, Sigma-Aldrich) at a density of 0.2 x104 cells per well. Cells were cultured in Neurobasal-A medium (Cat# 10888022, Thermo Fisher Scientific) supplemented with 1 % penicillin-streptomycin, 2 % B-27 Supplement (Cat# 17504044, Thermo Fisher Scientific), and GlutaMAX-I (Cat# 35050061, Thermo Fisher Scientific), CultureOne supplement (Cat# A3320201, Thermo Fisher Scientific). For control culture, we used either Ucp2fl/fl; Pomc-CreERT2; tdTomato mice which neuronal cultures were treated with vehicle (0.03 % ethanol diluted in medium) or Ucp2+/+; Pomc-CreERT2; tdTomato mice which neuronal cultures were treated with 2 μM 4-hydroxytamoxifen (Cat# H7904, Sigma-Aldrich). After 10 days in culture, primary neuronal cells isolated from control and Ucp2PomcKO mice were treated with 2 μM 4-hydroxytamoxifen for expression of a CreER recombinase. Primary neuronal cells were used for the measurement of mitochondria oxidation two days later. |
