Our new paper is out in @currentbiology.bsky.social! Using 3D reconstructions and volume measurements in Drosophila wing primordia, we show that growth can be uncoupled from cell proliferation and uncover a new time window for growth arrest.

A switch to non-proliferative growth sustains Drosophila wing development during the early pupal stage
Using precise tissue volume quantification, El Marzkioui, Gaugué, et al. show that
wing primordia continue to grow during the early pupal stage, a phase of increased
cell volume driven by insulin/IGF ...

My PhD work is out in Science Advances! We show how DPP drives tissue morphogenesis by encoding local mechanical programs iteratively, unraveling a self-organizing mechanism linking morphogen gradients to tissue dynamics.

Automorphy gets the morph into the morphogen.

We currently have a call for support that has gone out to European labs, to support FlyBase-UK. We are asking our colleagues from labs in the US and other countries to wait for a similar call to them that will go out in the near future, to support the US sites. We thank you for your patience.
URGENT: FlyBase has lost practically all its funding overnight; even user fees are tied up in denied grant funding. 🤬🤯
Any lab using @flybase.bsky.social please donate using the link in post below.
This incredible community, on whose backs our #Drosophila labs depend, can't be left out to dry.

My lab studies bacterial infections. We spend a lot of time looking at (or for) species-specific genetic and genomic databases for hosts and microbes. FlyBase is the best of all—there is literally no comparison. Its existence is under threat. Please donate.
