Description

Tabula Sapiens is a benchmark, first-draft human cell atlas of nearly 500,000 cells from 24 organs of 15 normal human subjects. This work is the product of the Tabula Sapiens Consortium. Taking the organs from the same individual controls for genetic background, age, environment, and epigenetic effects and allows detailed analysis and comparison of cell types that are shared between tissues. Our work creates a detailed portrait of cell types as well as their distribution and variation in gene expression across tissues and within the endothelial, epithelial, stromal and immune compartments.

Reference

Name Description Type Data type Size
obs
assay Type of assay used to generate the cell data, indicating the methodology or technique employed. vector category 483152
assay_ontology_term_id Experimental Factor Ontology (EFO:) term identifier for the assay, providing a standardized reference to the assay type. vector category 483152
batch A batch identifier. This label is very context-dependent and may be a combination of the tissue, assay, donor, etc. vector category 483152
cell_type Classification of the cell type based on its characteristics and function within the tissue or organism. vector category 483152
cell_type_ontology_term_id Cell Ontology (CL:) term identifier for the cell type, offering a standardized reference to the specific cell classification. vector category 483152
dataset_id Identifier for the dataset from which the cell data is derived, useful for tracking and referencing purposes. vector category 483152
development_stage Stage of development of the organism or tissue from which the cell is derived, indicating its maturity or developmental phase. vector category 483152
development_stage_ontology_term_id Ontology term identifier for the developmental stage, providing a standardized reference to the organism’s developmental phase. If the organism is human (organism_ontology_term_id == 'NCBITaxon:9606'), then the Human Developmental Stages (HsapDv:) ontology is used. If the organism is mouse (organism_ontology_term_id == 'NCBITaxon:10090'), then the Mouse Developmental Stages (MmusDv:) ontology is used. Otherwise, the Uberon (UBERON:) ontology is used. vector category 483152
disease Information on any disease or pathological condition associated with the cell or donor. vector category 483152
disease_ontology_term_id Ontology term identifier for the disease, enabling standardized disease classification and referencing. Must be a term from the Mondo Disease Ontology (MONDO:) ontology term, or PATO:0000461 from the Phenotype And Trait Ontology (PATO:). vector category 483152
donor_id Identifier for the donor from whom the cell sample is obtained. vector category 483152
is_primary_data Indicates whether the data is primary (directly obtained from experiments) or has been computationally derived from other primary data. vector bool 483152
self_reported_ethnicity Ethnicity of the donor as self-reported, relevant for studies considering genetic diversity and population-specific traits. vector category 483152
self_reported_ethnicity_ontology_term_id Ontology term identifier for the self-reported ethnicity, providing a standardized reference for ethnic classifications. If the organism is human (organism_ontology_term_id == 'NCBITaxon:9606'), then the Human Ancestry Ontology (HANCESTRO:) is used. vector category 483152
sex Biological sex of the donor or source organism, crucial for studies involving sex-specific traits or conditions. vector category 483152
sex_ontology_term_id Ontology term identifier for the biological sex, ensuring standardized classification of sex. Only PATO:0000383, PATO:0000384 and PATO:0001340 are allowed. vector category 483152
size_factors The size factors created by the normalisation method, if any. vector float32 483152
soma_joinid If the dataset was retrieved from CELLxGENE census, this is a unique identifier for the cell. vector int64 483152
suspension_type Type of suspension or medium in which the cells were stored or processed, important for understanding cell handling and conditions. vector category 483152
tissue Specific tissue from which the cells were derived, key for context and specificity in cell studies. vector category 483152
tissue_general General category or classification of the tissue, useful for broader grouping and comparison of cell data. vector category 483152
tissue_general_ontology_term_id Ontology term identifier for the general tissue category, aiding in standardizing and grouping tissue types. For organoid or tissue samples, the Uber-anatomy ontology (UBERON:) is used. The term ids must be a child term of UBERON:0001062 (anatomical entity). For cell cultures, the Cell Ontology (CL:) is used. The term ids cannot be CL:0000255, CL:0000257 or CL:0000548. vector category 483152
tissue_ontology_term_id Ontology term identifier for the tissue, providing a standardized reference for the tissue type. For organoid or tissue samples, the Uber-anatomy ontology (UBERON:) is used. The term ids must be a child term of UBERON:0001062 (anatomical entity). For cell cultures, the Cell Ontology (CL:) is used. The term ids cannot be CL:0000255, CL:0000257 or CL:0000548. vector category 483152
