We explore where the early field of spatial miRNomics stands, what’s missing, and why incorporating miRNAs matters for building richer spatial transcriptomic maps.

Our latest work is now live on bioRxiv! We use copy number variation inference to uncover tumor clonality from imaging-based spatial transcriptomics data. Check it out: doi.org/10.1101/2025...
In Situ Inference of Copy Number Variations in Image-Based Spatial Transcriptomics
Copy number variations (CNVs) drive cancer progression. So far, spatial CNV inference has relied on whole transcriptome-based sequencing technologies. However, advances in image‐based spatial transcriptomics (iST) now enable high-plex gene measurement in situ. Here, we introduce an approach that adapts CNV inference to iST data, enabling spatial mapping of malignant clones and the tumor microenvironment, at single-cell resolution. Additionally, we assess how panel size and detection efficiency influence CNV inference. ### Competing Interest Statement S.M.S is co-founder of spatialist AB, a spatial omics consultancy company.

Our field has lost an amazing scientist, mentor, and old friend. Benny, along with Mike Hoffman, had a brilliant idea in the early 1980s. The first oncogenes were being cloned and they realized if we wanted to understand their roles in cancer, we needed to understand their normal function 1/n 🧪

Immagine you could image two cellular structures in the same fluorescent channel and still reliably get them separated afterwards…
What would you do with this?

Now… what would you do if that also worked with 4 structures at once? 👇 #MicroSplit #preview🧵
