 CXCL1 is secreted by human melanoma cells, has mitogenic properties and is implicated in melanoma pathogenesis.CXCL1 is expressed by macrophages, neutrophils and epithelial cells, and has neutrophil chemoattractant activity.CXCL1 plays a role in spinal cord development by inhibiting the migration of oligodendrocyte precursors and is involved in the processes of angiogenesis, arteriogenesis, inflammation, wound healing, and tumorigenesis.
