Stem cell therapy for faecal incontinence: Current state and future perspectives.

Area of Science:

• Regenerative Medicine
• Gastroenterology
• Biomedical Engineering

Background:

• Faecal incontinence is a prevalent condition with significant quality of life impacts.
• Current treatments for faecal incontinence are often inadequate, necessitating novel therapeutic approaches.
• Stem cell therapy has emerged as a potential treatment modality since 2008.

Purpose of the Study:

• To review and summarize existing literature on the use of stem cells for treating faecal incontinence.
• To assess the safety and efficacy of stem cell therapies in preclinical and clinical settings for faecal incontinence.
• To explore the combination of stem cells with bioengineering for anal sphincter repair.

Main Methods:

• A narrative review of published studies on stem cell therapy for faecal incontinence.
• Inclusion of preclinical research involving muscle-derived and mesenchymal stem cells.
• Analysis of available clinical trial data and bioengineering approaches.

Main Results:

• Preclinical studies indicate safety and repair of anal sphincter injuries with stem cell injections (muscle-derived, mesenchymal).
• Encouraging functional outcomes have been observed in animal models.
• Bioengineered constructs using stem cells and scaffolds have been successfully created and implanted.
• Limited clinical evidence suggests adipose-derived stem cells and myoblasts are safe and show promising results.

Conclusions:

• Stem cell therapy demonstrates potential for treating faecal incontinence, with promising safety and functional results in early studies.
• The combination of stem cells with bioengineering offers a novel approach to creating functional anal sphincter constructs.
• Further extensive research in both animal models and human clinical trials is essential to validate these findings and establish stem cell therapy as a viable clinical option for faecal incontinence.
