In zebrafish, neural stem cells keep producing neurons throughout life. Pasteur scientists reveal how Notch3 signaling coordinates neighboring stem cells to maintain this balance, insights relevant to brain tumours.

Really excited to finally show off our work on the specification of neuroblasts. While it has been a long-standing model for lateral inhibition, we show that Notch does not select the NB, but instead reinforces fate decisions.

Positional cues, not Notch, direct neuroblast selection during early neurogenesis in the Drosophila embryo
Using quantitative live imaging, Green et al. show that proneural gene expression is biased by positional cues and that Notch is activated only after neuroblast selection in the Drosophila embryo. Thi...

In the lab we will study how differences in X-linked gene dosage between the sexes affect fetal growth and survival and contribute to sex differences later in life 👩‍🔬🧪🧬🧫

Choanoflagellates — our closest animal relatives — form multicellular colonies in two ways: cell division AND aggregation.

This previously unknown "mixed multicellularity" suggests our animal origins are more complex than thought.

It shows that #HSPCs expand while staying multipotent thanks to tightly controlled ROS levels regulated by developmental #mitophagy.
