This study demonstrates the polarization of neocortical organoids. By adding rostral (FGF8) and caudal (BMP4/WNT agonists) morphogens, neocortical organoids upregulate and downregulate anterior or posterior homeodomain transcription factors, including SP8 and COUPTF1. With the application of FGF8 or BMP4/WNT agonists, the formation of anterior or posterior organizers was observed in neocortical organoids. Single-cell RNA-sequencing analyses exhibited molecular signatures associated with different lobes/areas found in multiple studies using human fetal tissue.2026/09/09GSE296079GSM9486174GSM8964756GSM9486172GSM9486173GSM9486170GSM9486171GSM8964751GSM8964755GSM9486169GSM8964754GSM9486167GSM8964753GSM8964752GSM948616824676296079Homo sapiens[42624107]
