EMX1 and autism: In day-35 immature neurons, EMX1 expression in both control and autism neurons was reduced compared with the expression in day-9 and -21 precursors; however, the reduction was significantly more acute in the autism group (dCTA = −148 cells/day in control-iPSCs vs. dCTA = −254 cells/day in autism-iPSCs) (Figure 3C).
