Flt-3 Ligand/FLT3L Products

Flt-3 Ligand, also known as FLT3L, is a cytokine that promotes the differentiation or expansion of multiple hematopoietic cell lineages including monocytes, immature dendritic cells, and early B cell lineage cells. It synergizes with other cytokines to promote the myeloid differentiation and mobilization of hematopoietic stem cells, to induce NK cell development, and to induce terminal B cell maturation. Flt-3 Ligand/FLT3L is expressed as a dimer by T cells and bone marrow and thymic fibroblasts. Both transmembrane and soluble forms of Flt-3 Ligand/FLT3L signal through the tyrosine kinase receptor Flt-3/Flk-2.
