Researchers at Emory University are studying pancreatic stellate cells, so named because of their star-like appearance, isolated from mouse models of pancreatic cancer. The scientists are probing the tumor microenvironment that includes these cells, which are a type of fibroblast. Pancreatic stellate cells can secrete molecules that help tumors grow and suppress the immune system’s response.
