Name: | caudal hematopoietic tissue |
---|---|
Synonyms: | |
Definition: | Tissue that lies between the caudal artery and the caudal vein plexus where definitive hematopoiesis occurs after 48hpf and before the hematopoietic progenitors migrate to the thymus and kidney. |
Ontology: | Anatomy Ontology [ZFA:0005898] |
Name: | has fewer parts of type |
---|---|
Synonyms: | decreased number of, has decreased number of, has fewer physical parts of type |
Definition: | The bearer of this quality has_part < n AND has_part > 0 of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. |
Ontology: | Phenotypic Quality Ontology [PATO:0002001] |
Name: | hematopoietic stem cell |
---|---|
Synonyms: | colony forming unit hematopoietic, hematopoietic progenitor cell, hemopoietic progenitor cell, hemopoietic stem cell, HSC |
Definition: | A stem cell from which all cells of the lymphoid and myeloid lineages develop, including blood cells and cells of the immune system. |
Ontology: | Anatomy Ontology [ZFA:0009014] |
Tag: | ameliorated |
---|---|
Definition: | This annotation denotes a significantly rescued phenotype resulting from an additional reagent or mutation. |
