🚨 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.

Join us:

With @abigailsuwala.bsky.social we are looking for a postdoc to drive our spatial transcriptomics analysis efforts of brain tumours.

If you enjoy multidisciplinary biomedical research, big data and coding, you are in the right place.

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. 👏

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.

Integrated in vivo combinatorial functional genomics and spatial transcriptomics of tumours to decode genotype-to-phenotype relationships - Nature Biomedical Engineering A method integrates perturbation mapping with 10X Visium spatial transcriptomics to map tumour genetic complexity and heterogeneity.

This is a great set of methods for studying combinatorial effects of cancer mutations on spatial phenotypes.

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.

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.

Back then, the implementation was very clunky and could only be done by R experts.

ebmstate now makes the inference much easier with only a few lines of code.

From great collaborations come great things. Excited to share Segger, the solution to segmentation of spatial transcriptomics (ST) data, with the @steglelab.bsky.social and @moritzgerstung.bsky.social labs, spearheaded by the great Andrew Moorman and Elyas Heidari www.biorxiv.org/content/10.1...

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.

Segger comes as robust open-source software and has already been tested by many in the community. github.com/EliHei2/segg...

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.

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...

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...

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.

Congratulations! Looking forward to seeing the outputs of your scientific ingenuity becoming multiplied.
