909-Progenitor Niche in Benign-to-Malignant Transition
The paper details a scientific study identifying a progenitor-like cell state that serves as a critical intermediate during the development of pancreatic ductal adenocarcinoma (PDAC). These high-plasticity cells emerge following tissue injury and oncogenic KRAS activation, forming a self-reinforcing cancer-like niche that mimics the malignant environment. Research shows that this state is a site of intense conflict between tumor-promoting mutations and suppressive forces like p53, which normally works to dismantle these niches and restore tissue balance. By using mouse models and human tissue…
