Teleost growth factor independence (gfi) genes differentially regulate successive waves of hematopoiesis

► The paper analyses gfi-factors, gfi1aa and gfi1b, in zebrafish hematopoiesis. ► gfi1aa regulates the expression of gata-1 and primitive hematopoiesis. ► gfi1b regulates definitive hematopoiesis and its lineages.
