UT Southwestern Medical Center researchers have identified two distinct populations of cells known as antigen-presenting cancer-associated fibroblasts (apCAFs) that appear to support the survival and growth of malignant tumors. Their findings, reported in Cancer Cell, could one day lead to new therapies for notoriously hard-to-treat cancers, including pancreatic cancer and advanced colorectal cancer (CRC) that has spread throughout the abdomen, known as peritoneal metastasis.
