Gastric cancer organoids and their convergence in engineering approaches

Gastric cancer research has rapidly progressed due to interdisciplinary advances in stem cell biology and bioengineering. Gastric organoid models, particularly those derived from adult stem cells, have emerged as powerful tools that recapitulate the cellular complexity of the human stomach. This review highlights the development of various gastric organoid platforms, with a specific focus on the convergence of engineering strategies to overcome the limitations of conventional organoid systems. We explore how CRISPR-based functional genomics, matrix innovations, co-culture systems, microphysiological systems (MPS), and big data integration are collectively enhancing organoid models. Furthermore, we examine how artificial intelligence may refine the clinical relevance and precision of gastric organoid models. By assessing both current capabilities and future directions, this review offers a perspective on how gastric organoid systems may reflect human physiology more accurately and improve therapeutic outcomes.
