Bone metastasis continues to be the greatest challenge in treating patients with prostate cancer despite ongoing research. In bone, prostate cancer tumors hijack normal bone remodeling processes to drive cancer progression. However, it is unclear how these interactions drive bone-metastatic prostate cancer growth in the bone environment. To understand the mechanisms associated with bone-metastatic prostate cancer regulation of mesenchymal stem cells (MSC), we previously identified that bone-metastatic prostate cancer induces MSC expression of the pro-inflammatory chemokine CXCL8 and its mouse functional homologue Cxcl1. To date, there has been little to no information about the role of CXCL1/8 in MSC biology …
