Abstract:
BACKGROUND:Prostate cancer metastases to bone are associated with significant morbidity and mortality. Presently, there is little known about the biological interaction between prostate cancer cells and bone. Development of an animal model using adult human bone will enhance our ability to study the biology of prostate cancer metastasis to bone. METHODS:Bone was harvested from patients undergoing total joint arthroplasty and implanted in the hindlimbs of pre-treated SCID mice. Two months after bone implantation 4 x 104 prostate cancer cells (PC-3 or LAPC-4) were injected near the bone implantation site. The animals were sacrificed approximately 8 to 12 weeks after the injections of the cells. Complete histological analysis including immunostaining was performed. RESULTS:Both the PC-3 and LAPC-4 prostate cancer cells homed to the human bone implant, specifically the reconstituted bone marrow cavity. Analysis of the bone-tumor interaction after injection of PC-3 cells revealed strong labeling for PTHrP, TNF alpha and IL-6, consistent with osteoclast recruitment and osteoclast activity. These cells also were positively stained for CK18. After cellular injection of LAPC-4 cells, there was strong labeling for TNF alpha, IL-6, and IL-1 (osteoclast recruitment and osteolytic activity). PTHrP staining was also noted. The bone cells were strongly stained for osteocalcin, and the tumor cells for PSA. CONCLUSIONS:These data suggest that the tumor cells may induce an osteolytic response to enhance their ability to metastasize to bone. This animal model allows us to study the biologic interaction between prostate cancer cells and human bone and may enhance our understanding of the events associated with prostate cancer metastasis to bone.
