To enable more precise analyses of zebrafish hematopoietic progenitor cells, we have created zebrafish kidney stromal (ZKS) cell lines. Culture of kidney marrow with ZKS cells results in the maintenance and expansion of hematopoietic precursor cells. Hematopoietic growth is dependent upon ZKS cells, and we show that ZKS cells express many growth factors previously demonstrated to be important in maintaining mammalian hematopoietic cells. In the absence of exogenous growth factors, ZKS cells maintain early hematopoietic precursors and support differentiation of lymphoid and myeloid cells. With the addition of zebrafish erythropoietin, ZKS cells also support the differentiation of erythroid precursors. The development of robust in vitro assays now provide the means to track defined, functional outcomes for prospectively isolated blood cell subsets in the zebrafish.
