Possible origins of pancreatic cancer revealed
Pancreatic cancer is the fourth-leading cause of cancer death in the United States, killing an estimated 35,000 Americans each year. One of the reasons pancreatic cancer is so deadly is that it is hard to detect it in the early stages, and that’s partly because scientists aren't sure from which cell(s) it arises.Now, in findings that could help answer that question, MIT cancer biologists have identified a subpopulation of cells that can give rise to this disease. They also found that tumors can form in other, more mature pancreatic cell types, but only when they are injured or inflamed, suggesting that pancreatic cancer can arise from different types of cells depending on the circumstances. “By the time pancreatic disease is typically diagnosed, it’s already very advanced and non-curable. Our new findings can help scientists focus their drug development efforts and lead them to new ways to detect the disease in...
