Most tumours are never profiled with spatial transcriptomics, but nearly all are imaged. DeepSpot-M bridges that gap and as a first demonstration, we used it to build a virtual spatial transcriptomics atlas of 28,664 TCGA slides across 32 cancers, the largest resource of its kind
Our virtual spatial transcriptomics atlas of 11,000 patients across 32 cancer types is featured in the AI for Science collection on @hf.co, together with DeepSpot-M.

🚀 Check out our new population-scale virtual spatial transcriptomics atlas, generated with DeepSpot-M by computationally augmenting TCGA retrospective histopathology archives spanning 28,664 images from 10,865 patients across 32 cancer types. huggingface.co/datasets/rat...

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
