Macrophage inflammatory protein-1 alpha (MIP-1 alpha), also known as CCL3, is a member of the CC family of chemokines and is most closely related to CCL4 or MIP-1 beta. Mouse MIP-1 alpha signal through CCR1, CCR3, CCR5, and D6 receptors (Menten et al.). MIP-1 alpha exhibits a variety of proinflammatory activities in vitro, including leukocyte chemotaxis, cytokine production, and mast cell activation, and it inhibits the proliferation of hematopoietic stem cells in vitro and in vivo (Cook). MIP-1 alpha plays a critical role in macrophage recruitment into wounds and in tissue repair (DiPietro et al.). It has been demonstrated that blockade of the CCL3/MIP-1 alpha-CCR1 pathway blocks the recruitment of CCR1-expressing CD4+ T cells to the liver, showing a therapeutic potential for treating T cell-mediated liver diseases (Ajuebor et al.).

Human Recombinant IL-3 (CHO-expressed)

Supplier: STEMCELL Technologies

Interleukin 3 (IL-3) is a species-specific pleiotropic cytokine that promotes the survival and proliferation of pluripotent hematopoietic stem cells and lineage-committed progenitor cells and their differentiation into mature cells of most lineages, including basophils, neutrophils, eosinophils, macrophages, dendritic cells, erythrocytes, and megakaryocytes (Yang et al.; Dorssers et al.; Broughton et al.). IL-3 is produced by activated T cells and has a physiological role in inflammation and allergies by promoting the secretion of inflammatory mediators such as histamine, IL-4, and IL-6 by basophils and eosinophils (Broughton et al.). The IL-3 receptor consists of a unique alpha subunit (CD123) and a beta common subunit (βc or CD131) that is shared with the receptors for IL-5 and GM-CSF, and is the principal signal transduction subunit for these cytokines. IL-3 binding to the heterodimeric receptor activates JAK/STAT, MAPK, and PI3K signaling pathways (Woodcock et al.).

Human Recombinant Oncostatin M

Supplier: STEMCELL Technologies

Oncostatin M (OSM) is a member of interleukin 6 (IL-6) family of cytokines and bears close resemblance to leukemia-inhibitory factor (LIF) and granulocyte colony-stimulating factor (G-CSF) in amino acid sequence and its modulation of differentiation in a variety of cell types (Rose and Bruce). OSM signals through type I receptor (consisting of gp130 and LIF receptor (LIFR)) and type II receptor (consisting of gp130 and OSM receptor (OSMR)), which eventually activate the JAK/STAT pathway (Auguste et al.; Gómez-Lechón). OSM is primarily produced by activated T cells and monocytes, and also by activated macrophages, neutrophils, mast cells, and dendritic cells. OSM is also produced within the bone microenvironment by cells of both hematopoietic and mesenchymal origin including osteocytes and osteoblasts. OSM is involved in differentiation, cell proliferation, hematopoiesis, and inflammation, and also has been shown to have implications in liver development, bone formation and resorption (Sims and Quinn; Tanaka and Miyajima).
