Insights into Modeling Inflammatory Bowel Disease from Stem Cell Derived Intestinal Organoids.

Inflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC), is a multifactorial, immune-mediated condition marked by chronic gastrointestinal inflammation. This condition significantly impairs patients' quality of life and represents a major public health challenge globally. Pathogenesis of IBD arises from complex interplay among genetic predisposition, environmental factors, immune dysregulation, and microbial dysbiosis. Although significant strides have been made in unraveling these mechanisms, existing therapeutic options remain inadequate in addressing the full spectrum of clinical needs, underscoring the urgent demand for innovative strategies. Regenerative medicine has emerged as a promising frontier, offering novel tools for therapeutic development. We briefly consolidated current knowledge on IBD pathogenesis and treatments, emphasized the pivotal potential of human intestinal organoids (including adult stem cell-derived organoids and pluripotent stem cell- derived organoids) as a robust platform for mechanistic studies and treatment exploration. Leveraging this technology, we aim to advance personalized and next-generation therapies for IBD.
