Our research article, titled “FOXP Genes Regulate Purkinje Cell Diversity in Cerebellar Development and Evolution”, is published in bioRxiv ! In this study, we employ single-cell RNA sequencing and spatial mapping to identify previously unrecognized PC subtypes in the embryonic mouse cerebellum, shedding new light on the molecular heterogeneity of these cells and their relationship to adult cerebellar organization regulated by Foxp genes.
