Significant amounts of microRNAs (miRs) are detected in exosomes, but their function during fetal development is poorly understood. In this issue of Developmental Cell, Hayashi et al. (2017) show that exosomal miRs secreted by mesenchymal cells can regulate epithelial KIT progenitor cell expansion during murine salivary gland organogenesis.
大量的 microRNAs(miRs)存在于外泌体中,但其在胎儿发育过程中的功能尚不清楚。在本期《发育细胞》中,Hayashi 等人(2017)表明,间充质细胞分泌的外泌体 miR 可以调节小鼠唾液腺器官发生过程中的上皮 KIT 祖细胞的扩增。
