title: GSM7595835: Adrenal Medulla P15 stem cells; Mus musculus; RNA-Seq
library_construction_protocol: Mouse adrenals were dissected on ice, surrounding fat and excess adrenal cortex were removed manually. Medullae were placed in an enzymatic digestion mix containing 50μg/ml DNAse I (Sigma, D5025), 10mg/ml Collagenase II (Worthington, LS004177), 2.5μg/ml Fungizone (Gibco, 15290026), 0.1X Trypsin-EDTA (Sigma, 59418C) in 1X Hank's Balanced Salt Solution (HBSS) (Gibco, 14025050) and incubated at 37°C for 15 minutes. Enzymes were inactivated by addition of 10 times volume of serum-containing Base Media: DMEM/F-12 (Gibco, 31330-038) + 5% FBS (Merk, F0804) + 50U/ml Penicillin-Streptomycin (Gibco, 15070063). The cell suspension was centrifuged at 281g for 5 minutes at room temperature, washed twice in PBS and pellets were resuspended in a solution of HBSS 2.5% FBS. An aliquot of 10,000 viable cells were used for the experiment. For Sox2 enriched dataset, cells were sorted for GFP expression.
