IL11 is a multifunctional cytokine produced by stromal cells such as fibroblasts, epithelial cells and osteoclasts. It is expressed in a wide variety of tissues including thymus, lung, bone, connective tissue and central nervous system. IL11 plays an important regulatory role in hematopoiesis by stimulating growth of myeloid, erythroid and megakaryocyte progenitor cells. It also regulates bone metabolism, inhibits production of proinflammatory cytokines and protects against gastromucosal injury. Alternative Names: Interleukin 11 protein, AGIF protein, IL 11 protein, IL-11 protein, IL-11 protein, IL11, IL-11, Adipogenesis inhibitory factor protein, IL 11
