Bowel Regeneration: Bench to Bedside

Area of Science:

• Regenerative medicine
• Bioengineering
• Stem cell biology

Background:

• Pediatric intestinal failure from short bowel syndrome causes significant morbidity and mortality.
• Current treatments like parenteral nutrition and transplantation have limitations and complications.
• Native intestinal adaptation is insufficient for severe cases.

Purpose of the Study:

• To review current bowel regeneration strategies for pediatric intestinal failure.
• To examine cellular, biological, structural, and tissue engineering approaches.
• To discuss emerging technologies and their clinical translation potential.

Main Methods:

• Conceptual framework progressing from native adaptation to tissue engineering.
• Review of stem cell biology, biomaterials, mechanotransduction, and bioengineering.
• Discussion of gene editing, 3D bioprinting, and organoid-scaffold systems.

Main Results:

• Bowel regeneration field has rapidly expanded over two decades.
• Multiple strategies are being developed, integrating cellular and structural approaches.
• Emerging technologies show promise for future clinical applications.

Conclusions:

• Significant hurdles in vascularization, innervation, and scaling remain.
• Regenerative approaches are poised to transform pediatric intestinal failure management.
• The future trajectory suggests a fundamental shift in treatment paradigms.
