Collection ID:CO001890
Collection Summary:Astrocyte conditioned media (ACM) was obtained from immortalized astrocyte cell lines (a gift from Dr. David Holtzman) that were originally generated from primary astrocytes from P1-2 pups of APOE targeted replacement mice (42). The immortalized astrocytes were conditioned with Neurobasal media supplemented with B27, Glutamax-I, Normocin and 1% penicillin/streptomycin for 24 hours. This ACM was then collected, stored at -80ºC, and thawed prior to use. WT primary cortical neuronal cultures were obtained from embryonic day 17 (E17) C57Bl/6 embryos. Briefly, pregnant mice were euthanized by cervical dislocation and the embryo brains extracted. The meninges were carefully stripped off and the cortices dissected out. The cortices were then enzymatically dissociated in 0.25% Trypsin-EDTA and resuspended in Neurobasal media supplemented with B27, Glutamax-I, Normocin and 1% penicillin/streptomycin. Dissociated cells were counted and 300K neurons per well were plated directly into ACM in poly-D-lysine (PDL)-coated 6-well plates. ACM-treated neurons were then incubated at 37⁰C for 7 days in a humidified chamber with 5% CO2, with 50% media exchange (with newly thawed ACM) once every 3 days.
