Development (2019) 146 (2): dev170589.
Published: 29 January 2019
.... This is particularly true when studying kinases that have pleiotropic functions and multiple substrates. Drosophila neuroblasts (NBs) are rapidly dividing stem cells and an important model system for the study of cell polarity. Mutations in multiple kinases cause NB polarity defects, but their precise functions...

...Xiaosu Li; Yonggang Xie; Sijun Zhu Notch signaling is crucial for maintaining neural stem cell (NSC) self-renewal and heterogeneity; however, the underlying mechanism is not well understood. In Drosophila , loss of Notch prematurely terminates the self-renewal of larval type II neuroblasts (NBs...

Technau The numbers and types of progeny cells generated by neural stem cells in the developing CNS are adapted to its region-specific functional requirements. In Drosophila , segmental units of the CNS develop from well-defined patterns of neuroblasts. Here we...
