Database details • clustermole

We will load clustermole along with dplyr to help with summarizing the data.

library(clustermole)
library(dplyr)

You can use clustermole as a simple database and get a table of all cell type markers.

markers <- clustermole_markers(species = "hs")

Each row contains a gene and a cell type associated with it. The gene column is the gene symbol (human or mouse) and the celltype_full column contains the detailed cell type string including the species and the original database.

Number of cell types

Check the total number of the available cell types.

length(unique(markers$celltype_full))
#> [1] 3039

Number of cell types by source database

Check the source databases and the number of cell types from each.

Number of cell types by species

Check the number of cell types per species (not available for all cell types).
