Puesta a punto de un modelo in vitro para analizar el efecto de la presión en el crecimiento y morfología de células pancreáticas tumorales crecidas en 3D.

, 2023
Up until today, pancreatic cancer is one of the deadliest and fastest-killing cancers. A late diagnosis, the lack of effective therapies and the tumor’s chemoresistance are the principal causes of such elevated mortality rates. Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and its noticeable resistance to ...
