In mice, mature CD8+ T cells expressing and T-cell receptors were generated from ES cells after PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/13485127 co-culture on OP9-expressing Notch ligand, delta like 1 (OP9-DL1). Additionally, T-cell progenitors generated after stimulation by Flt-3 ligand and IL-7 were capable of reconstituting the T-cell compartments in sublethally irradiated Rag2-/- mice [71]. OP9-DL1 co-cultures with both iPS cell lines derived from murine splenic B cells and MEF also resulted in T-cell development with traceable CD44 and CD24 in addition to CD4 and CD8 markers, but are not committed to the CD19+ B-cell lineage in the presence of Flt-3 ligand and IL-7 [72]. In the presence of Flt-3 ligand, IL-15, IL-6, IL-7 and SCF, co-cultures of mouse ES cells with OP9 stromal cells generated natural killer cells with CD94/NKG2 receptors to combat certain tumor cell lines and major histocompatibility complex (MHC) class I-deficient lymphoblasts [73]. Co-culturing of human ES cells with OP9 cells induced CD34highCD43low cells, and subsequent culture of CD34highCD43low cells in OP9-DL1 cells in the presence of Flt-3 ligand, IL-7 and SCF generate functional T 2-Chloro-5-aminomethylthiazole cells that have a response to phytohemagglutinin stimulation [74]. After 10-day co-cultures of OP9 stromal cells with iPS cells derived from adult human dermal fibroblasts, CD34+ cells were harvested and subsequently cocultured on MS-5 stromal cells for another 21 days in the presence of SCF, Flt-3 ligand, IL-7 and IL-3, which were then capable of generating CD45+CD19+CD10+ pre-B cells Ethyl (4,5,6,7-tetrahydrothiazolo[5,4-c]pyridin-2-yl)carbamate hydrochloride [75]. Additionally, using human pluripotent stem cells, Ni and colleagues demonstrated that the generation of CD45+CD56+ and CD117 D94+ natural killer cells can inhibit HIV-1 infection [76], a possible potential to treat immunologic diseases in humans.Macrophages are differentiated from monocytes and function to regulate both innate and adaptive immunity to combat foreign particles including pathogens by stimulating the response of immune cells, such as lymphocytes. The putative surface markers for macrophages are CD11b (Mac-1), CD14 (ligand receptor of lipopolysaccharide), CD115 (colony-stimulating factor 1 receptor) and F4/80 (a highly glycosylated proteoglycan extracellular antigen). In mice, after EB formation of CCEG2 and D3 ES cell lines, the generated HPCs drive the development of macrophage that expresses F4/80 marker in the presence of Epo, IL-1, IL-3 and macrophage CSF [27]. From bone marrow-derived iPS cells, macrophages were generated after co-culture with OP9 stromal cells and further induced differentiation in the presence of fetal calf serum and macrophage CSF. These iPS-derived macrophages showed similar expression of F4/80 and CD11b surface markers and phagocytic capacity with those bone marrow-derived macrophages [77]. In humans, co-culture of ES cells with S17 cells, a mouse bone marrow-derived ijms17122034 stromal cell, were able to generate CD15-expressing macrophage progenitor cells [78]. After differentiating human ES cells by EB formation, monocytes and macrophages were induced in culture medium containing macrophage CSF and IL-3 [79].
