A spatial transcriptomics analysis led by my student Zaira reveals the distinct nature (gene expression, tumour cell states and local microenvironments) of radionecrosis and recurrence in glioblastoma. 👏

🚨 new glioblastoma preprint alert!

we present the first spatially resolved single cell atlas comparing radionecrotic changes (RN) and recurrent IDH-wildtype glioblastoma (GB) –– shedding light on a long-standing diagnostic challenge.

What if you could get a glimpse of the future of your health, today?

Our scientists have developed a new generative AI model, trained using large-scale health records, that can estimate how human health may change over time.

Watch to find out more.

How does tumour heterogeneity arise? How can we predict cancer cell plasticity? In 2 new studies, we trace #glioblastoma heterogeneity to a spatial cancer cell trajectory w. multimodal cell atlassing bit.ly/4mkrWgs & predict plasticity w. snRNA/ATAC+deep learning bit.ly/3FbI6Ic 🧵

Our experience with the multimodal seg is similar as yours- works great for many cell types or tissues, but not all.

Plus there can be contaminating transcripts on top.
moritzgerstung.bsky.social
Thank you! Yes, we believe segger has an edge over membrane-based segmentation because it also recognises the co-occurrence of transcripts. You can also use 10x multi-modal instead of nuclear segmentation as seggers input.

Some classical statistics today.

ebmstate, an R package for multistate models with empirical Bayes covariate effect estimation.

Developed by Rui Costa during his postdoc in my group.

1/ New preprint! 🍳

@elihei.bsky.social and our team at @embl.org , @dkfz.bsky.social, and @mskcancercenter.bsky.social built #segger - a fast, accurate cell segmentation tool for spatial transcriptomics that assigns transcripts to their cell origins!

Also tagging Elyas Heidari @elihei.bsky.social here who led this fantastic work.

A great thanks goes to all the other authors and contributors from the Gerstung, Stegle and Peer labs who made this work possible.
moritzgerstung.bsky.social
Andrew Moorman and other members of @danapeer.bsky.social's lab helped carry out a rigorous assessment based on various 10x Xenium data sets with bespoke segmentation stainings, providing the ground truth to demonstrate segger's superior performance.

Segger is a super fast graph neural network algorithm, which makes cell segmentation much more reliable and faster.

Spatial transcriptomics holds great promise to understand biological tissue function, but the assignment of transcripts to cells has been a substantial bottleneck.

For this reason, Elyas Heidari, a student in my lab and in @steglelab.bsky.social built segger.

Amazing work. We‘re all walking laboratories for somatic evolution.

Resharing here a recent X post. In this preprint, we introduce an improved version of NanoSeq, a duplex sequencing protocol with <5 errors per billion bp in single DNA molecules, and use it to study the somatic mutation landscape of oral epithelium in >1000 people. 1/ www.medrxiv.org/content/10.1...
Somatic mutation and selection at epidemiological scale
As we age, many tissues become colonised by microscopic clones carrying somatic driver mutations ([1][1]–[10][2]. Some of these clones represent a first step towards cancer whereas others may contribu...

Safe travels! We’re still waiting for the snow you got yesterday to arrive but chances look slim. Probably better travel wise.

Thanks. Was on a bit of a social media hiatus, but this place looks like a new hope.
