Abstract:no longer than 150 words) Homeostasis in high-turnover tissues depends on precise yet plastic regulation of stem cell daughter fates. In Drosophila, intestinal stem cells (ISCs) respond to unknown signals to switch from asymmetric to symmetric divisions during feeding-induced growth. Here, we show that this switch is controlled by dynamic reorientation of mitotic spindles by a Jun-N-terminal Kinase (JNK) / Wdr62 / Kif1a interaction. JNK promotes Wdr62 localization at the spindle and represses transcription of … Show more
