Seven populations of primary cortical cells were sorted based on SOX2 and PAX6 antibody staining, with n≥3 unique specimens and n = 9–16 technical replicates per population. Six populations of 100 in vitro cells were collected based on Cit fluorescence and stage (D26, D54, and D100), with N = 3–11 replicates per population. In vivo and in vitro cells were compared as described below.
