The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:The process of hematopoiesis occurring outside of the bone marrow (in the liver, thymus, and spleen) in the postnatal organisms.
Comment:During fetal life, the formation of cellular blood components occurs mainly in the liver, shifting to the bone marrow postnatally. SOme pathological conditions associated with a severe reduction of marrow hematopoiesis are associated with extramedullary hematopoiesis.
