Abstract
A method for the culture of hematopoietic cells and/or production of human cytokines using immortalized human stromal cell lines is provided. These immortalized stromal cell lines condition media such that the ability of the hematopoietic stem cells to self-replicate and/or differentiate is maintained by the media or the ability of the committed progenitors to expand and/or differentiate is maintained by the media. Further provided are irradiated and non-irradiated immortalized human stromal cells that synthesize cytokines, such as, IL-7, IL-8, IL-11, FLT3L, SCF, LIF, M-CSF, TGF-beta 1, GM-CSF, MIP-1alpha, G-CSF, and MCP-1.
