How can we predict spatial transcriptomics from histology images to enable simple, affordable, and reliable analysis of spatially resolved gene expression in routine clinical use? 🤔 Introducing DeepSpot – a deep learning model designed to tackle this! 🧵👇 www.medrxiv.org/content/10.1...

After years of research and continuous refinement, we’re thrilled to share that our paper on the MetaGraph framework — enabling Petabase-scale search across sequencing data — has been published today in Nature (www.nature.com/articles/s41...)
Efficient and accurate search in petabase-scale sequence repositories - Nature
MetaGraph enables scalable indexing of large sets of DNA, RNA or protein sequences using annotated de Bruijn graphs.

Older spot-level spatial transcriptomics datasets shouldn't be forgotten now that new single-cell methods exist. 🧬

Instead of discarding this rich resource, we can bridge the gap.
DeepSpot2Cell helps bridge the gap 👇

Just presented our new multimodal histopathology method "SpotWhisperer" at ICML, one of the largest AI conference.

SpotWhisperer enables spatially resolved annotation of histopathology images using natural language. We achieved this by "transferring" annotations from transcriptomic data. More soon!

🤝 Great collaboration between @bocklab.bsky.social (@moritzbaio.bsky.social, Animesh, Jake), @nonchev.bsky.social, @gxxxr.bsky.social, and pathologist Viktor Kölzer.

SpotWhisperer is at #ICML25 FM4LS workshop. Visit our poster on Saturday (19 July 2025) if you're interested & attending ICML. (6/6)

🚀 Excited to share that we've generated the largest digital spatial transcriptomics dataset using DeepSpot - over 56 million spatial transcriptomics spots from 3 780 TCGA samples across skin melanoma, renal cell carcinoma, lung adenocarcinoma, and lung squamous cell carcinoma cohorts. #pathology

First place award at the Autoimmune Disease Machine Learning Challenge organized by the @broadinstitute.org and CrunchDAO. Our approach outperformed competitors worldwide in predicting single-cell spatial transcriptomics from H&E images. 🎉
