Bone Abstracts

In prostate cancer TGFβ promotes invasion and metastatic potential. One well-known cellular source of TGFβ in the bone metastatic site is the bone-forming osteoblasts. Here we have studied the effects by human osteoblast-derived factors on metastatic potential in cells from the human bone metastatic prostate cancer cell line PC-3U and the primary prostate cancer cell line 22Rv1. Osteoblast-derived factors resulted in a morphological effect with an increase of long ce...
