Clinical applications and optimization of patient-derived organoids in intestinal diseases

Since the first successful establishment of organoids from adult intestinal stem cells, organoid technology has rapidly developed. With advances in normal organoid technology, intestinal disorders, such as colorectal tumors and inflammatory bowel disease, have been major target diseases for patient-derived organoid (PDO) development. PDO biobanking for colorectal cancer has subsequently been developed, and some reports have shown the possibility of using PDO models to predict anticancer drug responses. However, to apply these models to real-world practice, we need more long-term clinical follow-up data from further large-scale PDO biobanks, as well as advanced technology for more rapid and efficient PDO establishment. In addition, in the field of regenerative medicine, the implantation of healthy intestinal PDOs to refractory tissue defects could be a new treatment strategy to accelerate the healing and repair of mucosal defects. This PDO technology could also be applied to inflammatory bowel diseases and serve as a very useful model for drug development via high-throughput screening of useful candidate drugs.
