Next Monday, 3rd Feb at 2:30 pm, we are welcoming Prof. David Strutt from the University of Sheffield. This talk will be in person at PDN. Please come and join us if you are around Cambridge! Looking forward to seeing you soon👋

It's taken a while but final version of Alex's manuscript now out in eLife. We're proud of it – it was a difficult project with hard assays. Even the eLife editor admits it's 'useful' – and I'm not sure how often you see a genuinely useful paper these days?!

Looking for your first or next Postdoc position? Then don't look further, apply to this opportunity to join our lab to tackle the next big challenges in the Wnt signalling field. Experience in protein biochemistry and in vitro cell biology is essential for this post tinyurl.com/2p9rndfy

Interphase cell morphology defines the mode, symmetry, and outcome of mitosis During tissue formation, dynamic cell shape changes drive morphogenesis while asymmetric divisions create cellular diversity. We found that the shifts in cell morphology that shape tissues could conco...

My first post on Bluesky! Very excited to share our work just published in @science.org. We find that “Interphase cell morphology defines the mode, symmetry, and outcome of mitosis” - in angiogenesis and other tissues! www.science.org/doi/abs/10.1... www.science.org/doi/abs/10.1...

Development folks: the next Northern England Developmental Biology @bsdb.bsky.social @biologists.bsky.social meeting will take place on the 10th of July in Sheffield. Great speaker line-up, cheap registration fee and plenty of slots for ECR talks. Registration deadline=31/5, see poster for details

Bonus: This specially extended edition includes actually quite interesting reviewer figure 8.

Planar polarity in the Drosophila pupal wing is oriented by tissue stress but the mechanisms remain unclear. This study uncovers a crucial role for cell flow gradients in promoting planar polarity protein turnover and aligning proximodistal polarity.

New! 15y after the classic Aigouy et al "Cell Flow Reorients the Axis of Planar Polarity in the Wing Epithelium..." from lab of much missed Suzanne Eaton, we provide our take from post-doc Sara Tan "Tissue shear as a cue for aligning planar polarity in the developing Drosophila wing".

Now that my lab has moved to Emory I want you to join us in Atlanta. We have an NIH-funded postdoc position available to study Planar Cell Polarity (PCP) signaling using vestibular hair cells of the mouse as a model.

My quote of the day (or possibly the week/month/year):

‘Building organisms is about bringing #SelfOrganization under control’

I’m going to borrow this to use in my talks

Great – we'll try it (and hopefully report back!)

Don't seem to be many fly cell culture people on here, or maybe they are very shy... But suggestions still welcome while we're in the mood to test new reagents!

Two fields of spiky looking cells under a microscope. Left field has a few bright cells, the right field many bright cells. Left field labelled 'New Batch Effectene' the right field 'Old Batch Effectene'.

Drosophila cell culture people: we've been using Qiagen Effectene to transfect S2 cells with ~30% efficiency, but latest batch is only giving us <1% efficiency (so no use to us!!). Qiagen don't seem to have a solution.

Anyone got suggestions for other (good!) fly cell culture transfection reagents?

The Fat-Dachsous planar polarity pathway competes with hinge contraction to orient polarized cell behaviors during Drosophila wing morphogenesis Morphogenesis involves interactions between biochemical and mechanical cues. Trinidad et al. show that during Drosophila pupal wing morphogenesis, Fat-Dachsous planar polarity competes with tissue tension to control oriented cell behaviors. Moreover, junctional tension stabilizes Fat-Dachsous, supporting the existence of biomechanical feedback.

A little pre-Christmas reading for my planar polarity follower(s) – I’m sure there’s at least one of you!
