Our benchmark + guidelines for atlas-level differential gene expression of single cells is online:

Bottom line: Use pseudobulk + DESeq2 in simple and pseudobulk + DREAM in more complex settings.

I am excited to share my first work in @schapirolab.bsky.social on Multiple Myeloma (MM) in collaboration with the Standal Lab from NTNU Norway. We use Imaging Mass Cytometry (IMC) on bone marrow biopsies from MM and precursor patients (details below): www.biorxiv.org/content/10.1...
Highly multiplexed imaging recovers immune and metabolic niches in multiple myeloma associated with disease progression and bone involvement
Multiple myeloma (MM) is a cancer arising from genetically aberrant plasma cells (PCs) that remain dependent on the bone marrow (BM) microenvironment for disease establishment and progression. Here, w...

And for anyone who has considered contributing to an open source package: don't be scared to propose changes.

Even if it's not a complete and perfect solution, whoever is maintaining the package will help you in get to the right solution and they will be incredibly grateful.

For people like me who don't have a team behind a package like CellCharter, contributions like these mean a lot. So thank you Lukas :)

And congratulations, it's not always easy to jump into an existing codebase and propose changes.

RCS measures how large a cell niche (aka spatial domain aka spatial cluster) is compared to what would be normally expected.

This pushed me to completely rewrite the system for generating and plotting boundaries for cell niches.
The new system is now more efficient, consistent, and visually clear.

A few weeks ago, we released CellCharter v0.3.5.

Among some bug fixes, we received our first contribution from an external contributor: @loggas.bsky.social !

He designed a new metric called Relative Component Size (RCS).

Here it is! Bonsai. Now there is really no more excuse for using t-SNE/UMAP. Bonsai not only makes cool pictures of your data. It actually rigorously preserves its structure. No tunable parameters. Incredible work by @dhdegroot.bsky.social.
I'm so excited about this!

An alternative to tSNE & UMAP for more accurate data visualization:

Tree representations for distortion-free visualization and exploratory analysis of single-cell omics data.

The trees are constructed to accurately represent true distances between the objects in the high-dimensional space.

In an unprecedented move, the US National Institutes of Health has begun mass terminations of research grants that fund active scientific projects because they no longer meet “agency priorities”.

Exclusive: NIH to terminate hundreds of active research grants
Studies that touch on LGBT+ health, gender identity and DEI in the biomedical workforce could be terminated, according to documents obtained by Nature.

Does anyone have a good universal membrane marker besides NaKATPase and CD98, that ideally stains epithelium/cancer similarly strong as stroma/immune cells? Antibody will be used for spatial proteomics (cyclic IF), goal is a good whole cell segmentation downstream
