1/5 Cell identity is written in the proteome, not in the DNA, and not always in the RNA. Out on bioRxiv today: The first cell type-resolved, MS-based proteomic atlas of the human body. www.biorxiv.org/content/10.6...

Are you saying their are proteins being made not transcribed from any RNA? And there is RNA not encoded by DNA?

Excited to share a new preprint from the lab led by @lukekoblan.bsky.social and William Colgan in which we describe our efforts to define a quantitative cell fate map of mouse embryogenesis! www.biorxiv.org/content/10.6...

One key component of Perturb-Multi is in vivo Perturb-seq of formaldehyde-fixed tissue, enabled by the Flex reagents from @10xGenomics.

Perturb-Multi generates rich, multimodal data that can generate fundamentally new insights about the impact of genetic perturbations on tissue function. Check it out!

We used lentiviral delivery of sgRNAs to create genetic mosaic organs, separately knocking out hundreds of genes in the liver of a single mouse.

Perturb-Multi is a platform for pooled genetic screens in intact mammalian tissue with spatial (MERFISH and multiplexed immunofluorescence) and scRNA-seq-based phenotyping.

In collaboration with @weallen1 and Xiaowei Zhuang, we have developed Perturb-multi: biorxiv.org/content/10.1...

A platform for multimodal in vivo pooled genetic screens reveals regulators of liver function

Organ function requires coordinated activities of thousands of genes in distinct, spatially organized cell types. Understanding the basis of emergent tissue function requires approaches to dissect the...
