title: Directed differentiation of human embryonic stem cells to dendritic cells.
abstract: Embryonic stem cells represent a pluripotent population of cells capable of self-renewal, large-scale expansion, and differentiation in various cell lineages including cells of hematopoietic lineage. In this chapter, we describe a three-step cell culture method for directed differentiation of human embryonic stem cells (hESCs) to dendritic cells (DCs) that includes (1) hESC differentiation into hematopoietic progenitors by coculture with OP9 stromal cells, (2) expansion of myeloid DC precursors in suspension bulk cultures with granulocyte monocyte-colony stimulating factor (GM-CSF), and (3) differentiation of myeloid precursors to DCs in the serum-free medium with GM-CSF and interleukin-4 (IL-4). The method employs cell culture conditions selecting an almost pure population of myeloid DC precursors and does not require isolation of hematopoietic progenitors. With this method, hESCs can be differentiated to functional DCs within 30 days at an efficiency of at least four DCs per single undifferentiated hESC. Directed differentiation of DCs from hESCs could be useful for studying cellular and molecular mechanisms of DC development and potentially for the generation of antigen-presenting cells for cellular immunotherapy.
