CellMarker Search By Gene

Search the CellMarker 2.0 database for cell types that express a given marker gene. Returns curated cell type annotations from single-cell RNA-seq studies and experimental literature. CellMarker 2.0 covers >500 cell types across >400 tissue types in human and mouse. Use this to identify which cell types a gene marks, enabling cell type annotation in scRNA-seq analysis. Example: CD3D marks T cells, CD68 marks macrophages, EPCAM marks epithelial cells.
