[Effects of biomechanics on colorectal organoid culture]

In recent years, organoids have become a crucial model for studying the physiopathological processes in tissues and organs. The emergence of organoids has promoted the research on the mechanisms of the occurrence and clinical translation of diseases. Among these organoid models, colorectal organoid models are increasingly mature. Colorectal cancer is a common gastrointestinal malignant tumor worldwide, posing a serious threat to human health. Colorectal organoids provide a new model for studying the pathophysiology, drug sensitivity, and precision medicine of colorectal cancer. The conventional culture systems of colorectal organoids focus more on the role of biochemical factors, neglecting the fact that the gut is also influenced by biophysical signals in vivo. Therefore, in this review, we discuss the theories related to colorectal organoids and biomechanics and expound the effects of biomechanics on colorectal organoid culture.
