An astrocyte's intricate morphology is essential for proper brain function, but the intrinsic and extrinsic cues that set astrocyte morphology are largely unknown. In this issue, Tan et al. (https://doi.org/10.1083/jcb.202303138) show that layer-specific expression of neuronal cadherins locally regulates astrocyte morphogenesis and heterogeneity.
星形胶质细胞复杂的形态对于大脑功能的正常运作至关重要,但控制星形胶质细胞形态的内在和外在线索在很大程度上仍是未知的。在本期杂志中,Tan 等人(https://doi.org/10.1083/jcb.202303138)表明,神经元钙黏蛋白的层特异性表达局部调节星形胶质细胞的形态发生和异质性。
