How much hands-on lab expertise gets lost? We developed a multimodal AI agent that turns videos into protocols and detects procedural errors. Making science accessible. Great collaboration with #Google.

In labs, hands-on expertise is often lost because it's not written down. We leverage multimodal AI agents to capture & share expertise by analyzing video and speech to generate protocols, detect errors, and guide researchers. #AI #TeamMassSpec

Our extensive documentation and tutorials make scPortrait easy to use and accessible.
And as part of @scverse.bsky.social it’s compatible with existing tools like scanpy, squidpy, bento-tools or Moscot 🚀🐍

We also ship a benchmark dataset of Golgi morphologies and use it to compare image featurization tools: #ConvNeXt, #SubCell, #CellProfiler

✨ Embedding images into transcriptome atlases ✨
We use scPortrait to embed single-cell images from a @10xgenomics.bsky.social Xenium ovarian cancer dataset into the #SCimilarity transcriptome atlas (R2 = 0.65), recovering meaningful cell types

✨ Morphology defined cell states ✨
Image embeddings generated with scPortrait resolve intra- vs extratumoral macrophages with distinct morphologies, linked to anti-inflammatory vs fibroblast-like programs

✨ Transcriptomes from images ✨
Using optimal transport + flow matching, scPortrait generates gene expression directly from CODEX images, capturing canonical marker expression like TCL1A in germinal centers in the tonsil

With standardized single-cell image datasets in place, the key question is: what new biology can we unlock?
We highlight three use-cases for scPortrait

mannlab.bsky.social

The new .h5sc format provides fast random access to single-cell images for ML training.
It follows #FAIR data principles (findable, accessible, interoperable, reusable) and integrates with @scverse.bsky.social tools via AnnData.

The scPortrait pipeline transforms raw input images step by step:
• stitch FOVs
• segment & extract cells
• output standardized .h5sc single-cell image datasets

From messy pixels → inputs ready for training 🖥️

Problem: microscopy images are messy, fragmented, and hard to use for ML
Solution: scPortrait standardizes them into a new .h5sc single-cell image format turning 🔬microscopy images into a reusable resource for integrative cell modeling

Microscopy images are:
📈 easy to acquire across scales (organism → subcellular)
🖥️ information-rich (cellular architecture, tissue structure, perturbation responses)
= 🚀 ideal fuel for foundation models of cell behavior

AI has had major breakthroughs (#alphafold #chatgpt) & computational models can now detect patterns in complex datasets without external guidance 🧠🖥️

🧬 biological datasets often contain entangled information making them complex to interpret →🧠🖥️ + 🧬 = unlock new biology

Tomorrow’s large scale cross-modality models will further unlock biology, but they need standardized inputs. With @sophia-maedler.bsky.social & @nik-as.bsky.social, we built #scPortrait, @scverse.bsky.social package to turn microscopy images into single-cell image datasets for multimodal modeling

mannlab.bsky.social
Our preprint on scPortrait is out! We built a framework + format to turn microscopy into standardized single-cell image datasets. #scPortrait scales >100M cells, integrates with @scverse.bsky.social, & enables cross-modality modeling from morphology to transcriptomics

Congratulations on the inaugural of #AITHYRA, the new Biomedical AI institute in Vienna. Thank you for the invitation to speak at the symposium and the fascinating discussions on AI × proteomics. #AIforLifeScience

Withdrawal of the stem-cell niche WNR (Wnt-Noggin-R-spondin) cocktail in organoid cultures decreased proliferation and stemness, as well as improved differentiation, moving organoids toward more tissue-like states.

scDVP’s high-resolution enabled us to observe fine-grained protein abundance changes along the colon crypt axis. For instance, the abundance gradient of CA1 was only visible in organoid transplants and in vivo tissue.

mannlab.bsky.social
We further employed scDVP to explore differences in individual intestinal epithelial cells. This dataset comprised about 2,700 proteins across cell types, and confirmed clearer stemness-to-differentiation programs after organoid xenotransplantation.

mannlab.bsky.social
Led by @freddyomics.bsky.social‬ and @hausmannannika.bsky.social‬, we created a spatial human colon resource consisting of almost 8,000 protein groups across distinct cell types! This reference enabled us to assess cell populations of human colon organoids and establish a colon stemness signature.
