All cells were dissociated using accutase (Stem cell technologies) for thirty minutes, then resuspended in Neurobasal/B27 with Y27632 (10μM; Tocris) and sorted on a BD FACS Aria II (SSC gating/FSC gating/DAPI negative exclusion gating for live cells). For post-sort analysis, data was processed using FlowJo (Treestar) software.
