趋化因子CXCL7（英语：Chemokine (C-X-C motif) ligand 7，CXCL7）是一个人类基因。其编码的蛋白质为趋化因子（C-X-C基序）配体7 Chemokine (C-X-C motif) ligand，是一种CXC趋化因子类细胞因子，其蛋白异型体为β-血小板球蛋白或原血小板碱性蛋白（英语：Pro-Platelet basic protein，PPBP）。

这种蛋白在血小板活化时被大量释放 ，能刺激多种过程，包括有丝分裂、细胞外基质的合成、糖代谢和纤溶酶原激活物的合成。

Chemokine (C-X-C motif) ligand 7 (CXCL7) is a human gene.

The encoded protein, Chemokine (C-X-C motif) ligand is a small cytokine belonging to the CXC chemokine family. It is an isoform of Beta-Thromboglobulin or Pro-Platelet basic protein (PPBP).

It is a protein that is released in large amounts from platelets following their activation. It stimulates various processes including mitogenesis, synthesis of extracellular matrix, glucose metabolism and synthesis of plasminogen activator.
