W/ the spirit of St Jordi🐉, I read my favorite book (only 3 chaps, though).
"Scaling: Why is Animal Size so Important?" taught me animal size dictates many parameters, including time. Rather than real clock time, using physiological time helps understand animals comprehensively

Our paper is out! Xenopus embryos follow
#kleiber’s power law between metabolic rate and body mass. But triploids embryos which are made of fewer larger cells have a lower metabolic rate than diploids. 1/3

Can we predict cellular forces just from microscopy ?
We are happy to release a robust method by @SachaIchbiah to create 3D atlases of relative cell mechanics in embryos or tissues from fluorescent images of cell outlines:

3D cell neighbour dynamics in growing pseudostratified epithelia
The 3D shape and dynamic organization of epithelial cells are far more complex than previously believed, but can be explained with simple physical principles based on lateral surface energy minimisation.

Organoids in high-throughput and high-content screenings

Organoids in high-throughput and high-content screenings
Organoids are self-organized three-dimensional (3D) multicellular tissue cultures which derive from cancerous and healthy stem cells, sharing a highly similarity to the corresponding in vivo organs. Since their introduction in 2009, they have emerged as a valuable model for studying early embryogenesis, organ and tissue development, as well as tools in drug screening, disease modeling and personalized therapy. Organoids can now be established for various tissues, including brain, retina, thyroid, gastrointestinal, lung, liver, pancreas, and kidney. These micro-tissues resemble the native organ in terms of gene expression, protein expression, tissue architecture and cell-cell interactions. Despite the success of organoid-based research and the advances in patient-derived organoid culture, important challenges remain. In this review, we briefly showcase the evolution from the primary 3D systems to complex, multilayered 3D structures such as assembloids, gastruloids and ETiX embryoids. We discuss current developments in organoid research and highlight developments in organoid culturing systems and analysis tools which make organoids accessible for high-throughput and high-content screening. Finally, we summarize the potential of machine learning and computational modeling in conjunction with organoid systems.
