ASCT+B Cell Types Data from Azimuth Reference Data With Summaries


ASCT+B tables represent cell by gene (CxG) relationships that are also captured in the HuBMAP Azimuth references. This site provides the cell type typology for all existing Azimuth annotated reference datasets; the Azimuth cell type typology trees can be visualized in the ASCT+B Reporter.

We also provide easy access to results for comparing CxG in ASCT+B vs. CxG in Azimuth. In Jan 2022, Azimuth supports single-cell RNA-seq data exclusively. As more experimental data becomes available and additional types of data are supported (e.g., proteins, lipids, metabolites), data differences will decrease.

Azimuth Cell Type Typologies and Counts

In Jan 2022, eight molecular reference maps for human are available via Azimuth. For each we provide the cell type typology as a file that can be visualized in the ASCT+B Reporter together with a table that lists the annotation level and the number of cell types for each unique cell in the organ-specific Azimuth reference, see Table 1.

Comparison of CxG in ASCT+B vs. Azimuth

Table 3 shows the comparison of the CxG matrix in ASCT+B tables vs. CxG matrix in Azimuth for each organ in Jan 2022. An automatically generated, up-to-date comparison is available here; this xls also contains separate sheets with cell types that are not (yet) covered in the ASCT+B tables. Details on how the comparison is calculated are on GitHub. Note that not all Azimuth cell types have CL IDs; in these cases, matching is done based on cell type names.
