Extended Data Figure 2. hFBCs are mixed neuronal cultures with a substantial representation of cortical neuronal subtypes.

a, Quantile distribution constructed from combined log-gene expression levels of five unstimulated hFBC samples, with associated colour scale (see Methods). b–e, Expression of selected marker genes classified by neuronal subtype (b), glial cell type (c), brain region (d), neural progenitor cell type (e), and non-neural cell type (f).
