New work from @spinalorga.bsky.social & co PAX3 doesn't just pattern the dorsal neural tube, it links metabolism to mechanics PAX3 sustains upper glycolysis and mannose-dependent glycosylation, which cluster N-cadherin & strengthens adherens junctions www.biorxiv.org/content/10.6...

Transcriptional coupling of metabolism and cell mechanics controls human neuroepithelium morphogenesis
Tissue morphogenesis integrates developmental programs with cell mechanics, yet the mechanisms coupling these processes remain poorly understood. We investigated this link during neuroepithelial morph...

Excited to share our new #preprint uncovering how early human forebrain is patterned. Compared to mouse, human dorsoventral and anteroposterior telencephalon patterning is strikingly delayed, which is correlated with SHH and FGF signalling differences. Read it here: www.biorxiv.org/content/10.6...

How can we hope to understand organismal development when it is controlled by huge, complex networks of interacting genes? 
One option is to move away from molecular details and focus on learning representations and rules. Check out the new perspective from me and @jamesbriscoe.bsky.social

Happy to announce that our latest paper is now out! Have you ever wondered how neural tissues control their size? In this paper, we show that cell division orientation is critical in both the cortex and retina. www.science.org/doi/10.1126/...
science.org
Oriented cell divisions induce basal progenitors and regulate neural expansion across tissues and species
A fundamental role for division orientation in progenitor output driving cortical and retinal growth is revealed.
