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.

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 |

tissue | Specific tissue from which the cells were derived, key for context and specificity in cell studies. | 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 |
