Core Tip

Core Tip: We optimized the endoscopic ultrasound puncture process to obtain pancreatic cancer tissue and cultivate pancreatic cancer organoids. Adequate material from the first puncture, rapid and accurate puncture operations, and rapid entry of puncture samples into the culture stage are important factors for successfully cultivating pancreatic cancer organoids. Organoid activity is the key to long-term expansion.
