Cell-based therapy for preventing postoperative adhesion and promoting regeneration after hepatectomy

Area of Science:

• Regenerative Medicine
• Surgical Innovation
• Hepatology

Background:

• Postoperative adhesion is a significant complication following abdominal surgeries, including liver resections.
• Adhesions complicate reoperations, increase morbidity, and are particularly problematic after repeated hepatectomy for recurrent liver cancer.
• Current adhesion prevention methods are suboptimal.

Purpose of the Study:

• To evaluate a novel cell sheet therapy using fetal liver mesothelial cells (FL-MCs) for preventing postoperative adhesions.
• To assess the impact of FL-MC sheets on liver regeneration after repeated hepatectomy.
• To address the dual challenges of adhesion formation and impaired liver recovery in repeated hepatectomy models.

Main Methods:

• Development of a novel mouse model for repeated hepatectomy.
• Application of a fetal liver mesothelial cell (FL-MC) sheet post-surgery.
• Assessment of adhesion formation and liver regeneration parameters.

Main Results:

• The FL-MC cell sheet significantly reduced postoperative adhesion formation.
• FL-MC sheets promoted hepatocyte proliferation and improved liver regeneration after hepatectomy.
• The cell sheet therapy demonstrated potential for addressing both adhesion and regeneration issues.

Conclusions:

• Fetal liver mesothelial cell sheets offer a promising dual therapeutic strategy for repeated hepatectomy.
• This approach could mitigate complications from adhesions and enhance liver function recovery.
• FL-MC cell sheets represent a novel solution for improving outcomes in liver surgery patients.
