Current Status of Intestinal Stem Cell Research: Mechanisms, Intestinal Diseases, and Organoid Development

Area of Science:

• Gastroenterology and Regenerative Medicine
• Stem Cell Biology
• Molecular and Cellular Biology

Background:

• Intestinal stem cells (ISCs) are crucial for maintaining intestinal homeostasis and repair.
• ISC research has significantly advanced understanding of intestinal physiology and disease pathology.
• ISCs are implicated in various diseases and are targets for novel therapeutic strategies.

Purpose of the Study:

• To provide a comprehensive review of the current state of intestinal stem cell (ISC) research.
• To elaborate on the multi-level regulatory mechanisms governing ISCs.
• To summarize the involvement of ISCs in diseases and their applications in organoid technology.

Main Methods:

• Literature review and synthesis of current research on intestinal stem cells.
• Analysis of regulatory mechanisms including niche cells, signaling pathways, gut microbiota, extracellular matrix, and epigenetic regulation.
• Summary of ISC involvement in colorectal cancer, inflammatory bowel disease, radiation injury, and short bowel syndrome.

Main Results:

• ISCs are regulated by complex multi-level mechanisms involving niche, signaling, microbiota, ECM, and epigenetics.
• ISCs play significant roles in colorectal cancer, inflammatory bowel disease, radiation-induced intestinal injury, and short bowel syndrome.
• ISC-derived organoid technology offers promising avenues for disease modeling and therapeutic development.

Conclusions:

• Continued research into ISC regulation and function is essential for understanding intestinal physiology and pathology.
• Integrating advanced technologies like organ-on-a-chip and gene editing will accelerate clinical translation of ISC discoveries.
• This review serves as a valuable reference for researchers advancing the field of intestinal stem cell biology.
