Tumor Rejection by Modulation of Tumor Stromal Fibroblasts
Interleukin (IL)-4-secreting tumors are rejected in mice, an effect that is thought to be immune mediated. However, solid tumors are embedded in a stroma that often contains tumor-promoting fibroblasts, a cell population whose function is also affected by IL-4. Here we show that IL-4-secreting tumors grew undiminished in IL-4 receptor (R)-deficient (IL-4R-/-) mice. In IL-4R+/+ mice they were lo...
متن کاملCancer-associated stromal fibroblasts promote pancreatic tumor progression.
Pancreatic adenocarcinoma is characterized by a dense background of tumor associated stroma originating from abundant pancreatic stellate cells. The aim of this study was to determine the effect of human pancreatic stellate cells (HPSC) on pancreatic tumor progression. HPSCs were isolated from resected pancreatic adenocarcinoma samples and immortalized with telomerase and SV40 large T antigen. ...
متن کاملPancreatic Cancer Cells through Tumor-Stromal Interactions Radiation to Stromal Fibroblasts Increases Invasiveness of Updated Version
Radiotherapy represents a major treatment option for patients with pancreatic cancer, but recent evidence suggests that radiation can promote invasion and metastasis of cancer cells. Interactions between cancer cells and surrounding stromal cells may play an important role in aggressive tumor progression. In the present study, we investigated the invasive phenotype of pancreatic cancer cells in...

متن کاملStromal Fibroblasts in Cancer
Tumors are highly complex tissues composed of neoplastic cells and, in the case of carcinomas, stromal cell compartments containing a variety of mesenchymal cells, notably fibroblasts, myofibroblasts, endothelial cells, pericytes, and a variety of inflammatory cells associated with the immune system. Fibroblasts and myofibroblasts often represent the majority of the stromal cells within various...
