Figure Lengend Snippet: Fig. 7 A novel mechanism underlying the contribution of primary cancer to lung metastatic niche formation in breast cancer. Primary cancer- secreted CXCL17 increases the accumulation of CD11b+Gr-1+ MDSCs in the lungs, which produce PDGF-BB, resulting in enhanced angiogenesis in the lung tissue before cancer cells’ arrival. In addition, CXCL17 also drives CD11b+Gr-1+ MDSCs to exhibit supportive activity for cancer extravasation and survival by PDGF-BB production under cancer cell arrival
