The Single-Cell Muscle Project (scMuscle) aims to collect, analyze, annotate, and provide to the research community skeletal muscle transcriptomic data. This includes tools to visualize and re-analyze these data in a consistent and repeatable manner.
If you have a dataset that you would like to see included in a future version of this project, please fill out this survey! Any species, any age, any disease, any muscle-related cell line or organoid!
We used more than 100 single-cell and single-nucleus RNA sequencing datasets, from 14 different research groups, to build an integrated transcriptomic reference of murine skeletal muscle. The resulting compendium has ~365,000 cell/nucleus, which we have annotated using a suite of existing software tools (see linked preprint for more details).
Here, you'll find all of the R scripts used for the analysis and visualization (R_scripts/) as well as some of the supplemental resources we generated (supplemental_data/). These resources include metadata details, outputs from differential gene expression analysis, and some other useful gene lists.
You will also find the development version of the code used in our web application (web_app/), as well as details on different versions of the data (data_versions/)
