Was lovely to see many of you @ I2K! Despite having major FOMO about missing so much stuff this fall (GloBIAS! CytoData! FoundingGIDE! CBIAS!), conferences ARE usually a great way to find @erinweisbart.bsky.social and I. In Episode 19, we talk through great societies/meetings we think you'll enjoy!

Today is the last chance to register for #CytoData2025. Don’t miss a fantastic program covering the full spectrum of image-based profiling!

New work from Iva Buljan @ivabuljan.bsky.social in our lab!
We mapped how human tissue architecture changes with age using ~25k histology slides from 983 donors.
This is the first body-wide atlas of human microanatomy.

Our analysis reveals distinct recurrent CRC trajectories:
🤝 Tumor-CAF metabolic cooperation with immune shielding
🔥 Glycolytic shift with vascular remodeling and myeloid enrichment
Same disease, different mechanisms, suggesting different treatment responses.

GitHub - HartmannLab/MuVIcell: From cell-type stratified features to multicellular coordinated programs From cell-type stratified features to multicellular coordinated programs - HartmannLab/MuVIcell

🧩 To identify which changes co-occur in patients, we built MuVIcell, an open-source Python package that applies the MuVI factor analysis framework to model all spatial, metabolic, morphological, and compositional features per cell type.

⏳ What shifts with pT stage?
Early lesions show high proliferation and fatty acid oxidation capacity. Later, glycolysis rises, stroma and vasculature reorganize, and lymphocytes give way to myeloid cells. Spatial architecture predicts stage better than composition or metabolic state.

Robust multicellular programs dissect the complex tumor microenvironment and track disease progression in colorectal adenocarcinomas Colorectal cancer (CRC) is highly heterogeneous, with five-year survival rates dropping from $\sim$90% in localized disease to $\sim$15% with distant metastases. Disease progression is shaped not only...

🧭 Colorectal cancer doesn’t follow a single path.
Using spatial proteomics on ~500 tumors, we found distinct trajectories from early to late stage, involving the whole tumor microenvironment and its metabolic state.

Check out this opportunity to join my lab as a postdoc! www.ebi.ac.uk/research/pos...

Every year, faculty from EMBL-EBI and the Wellcome Sanger Institute co-develop projects that allow fellows to be part of ✨both✨ of these amazing research institutes.

This project has been in the making for quite some time. CORNETO not only integrates key concepts and methodologies in biological network inference, but also introduces a novel framework for multi-condition analysis. Congrats to the team, and especially to @pablormier.bsky.social for leading this.
