Tools to analyse early heart morphogenesis in detail are limited. @noelresearchlab.bsky.social &co develop computational package called morphoHeart that allows for integrated 3D analysis of both #heart & extracellular matrix morphology in live #zebrafish embryos 🧪 @plosbiology.org plos.io/42DlqtJ

Maximum intensity projection of a live embryonic zebrafish heart at 72 hours post fertilisation, showing myocardial actin (green; Tg(myl7:LifeActGFP)) and endothelial actin (magenta; Tg(fli1a:Ac-TagRFP)). The image is overlaid in the atrium with 3D reconstructions of the myocardial (light blue), endocardial (pink) and extracellular matrix (orange), and in the ventricle with a 3D reconstruction of the myocardium colour-coded to visualise myocardial thickness.

Spheroids are simple systems with only convex curvature. What about more complex systems? We teamed up with @tobyandrews.bsky.social & @rashmi-priya.bsky.social, and analyzed the ventricular myocardium of Zebrafish hearts ... and it works! 👇 (Directors: high alignment = red, misaligned = blue)

How can we accurately measure features on curved 3D tissues? 📐 Normally we rely on lossy 2D projections, but @juliaeckert.bsky.social's new method detects nematic orientation fields on surfaces of arbitrary geometry We tested it in hearts, and works a charm! 🫀 More in Julia's thread below 👇🏻

The outer ear is a mammalian innovation but where did it come from? In our study in Nature, Mathi Thiruppathy and colleagues find that the outer ear arose from modification of an ancestral gill program first originating in marine invertebrates. www.nature.com/articles/s41... 1/n
