Pick a cell type to discover which genes define its identity — and how that definition shifts across 12 human organs. Built on CellTypist regularized ML classifier weights.
How to read this atlas
A discriminative gene is one that distinguishes this cell type from the others in the same organ — not just a gene that happens to be switched on.
Shared / universal identity = genes that define the cell type in many organs — bright across a whole row of the heatmap.
Tissue-adapted identity = genes that define it in only one organ — a single bright cell in a row.
