Recombinant Human CCL23 (M1236-25ug)

Chemokine (C-C motif) ligand 23 (CCL23), also known as MPIF-1, is a small cytokine belonging to the CC chemokine family (1). It is most closely related to CCL15. CCL23 is predominantly expressed in lung and liver tissue but is also found in bone marrow, placenta and cells of the myeloid lineage (2). CCL23 induces endothelial cell migration and tube formation. It also enhances the expression of MMP-2 mRNA and protein levels in endothelial cells. CCL23 may play a direct role in angiogenesis (3). It is highly chemotactic for resting T cells and monocytes and slightly chemotactic for neutrophils and has also been attributed to an inhibitory activity on hematopoietic progenitor cells (2). CCL23 has been shown to suppress the low proliferative potential colony-forming cells that give rise to granulocyte and monocyte lineages.
