  • We tested the hypothesis that the stromal cells from PZ and transitional zone (TZ) have differential effects on the ability of tumorigenesis. (jcancer.org)
  • Stromal cells isolated from the PZ and TZ of normal human prostates mixed with DU145 cells subcutaneously injected into athymic nude mice. (jcancer.org)
  • The C-Kit inhibitor, imatinib mesylate, was administrated to confirm the effect of stromal cells on the tumorigenesis. (jcancer.org)
  • The volume and weight of tumors were significantly higher in mice transplanted with DU145 and stromal cells from PZ. (jcancer.org)
  • These effects of the stromal cells in the PZ on DU145 cells could be blocked using imatinib mesylate. (jcancer.org)
  • In malignancy, the adoption of mesenchymal phenotype by the malignant cells allows stromal invasion and subsequent intravasation to blood- or lymphatic vessels, a route that is a prerequisite for metastasis. (bso14.org)
