Cell-Based Therapies in Lower Urinary Tract Disorders.

Area of Science:

• Regenerative Medicine
• Urology
• Biomaterials

Background:

• Cell-based therapies for bladder reconstruction emerged in the 1990s with bladder smooth muscle cell isolation.
• Current approaches involve implanting native or stem cell-derived cells as injectables or grafts.

Purpose of the Study:

• To critically review literature on cell types for non-drug, non-bowel bladder replacement therapy.
• To discuss limitations and potential improvements for novel bladder regenerative therapies.

Main Methods:

• Literature review of cell-based strategies for urinary bladder disorders.
• Analysis of native cell types and stem cell-derived cells for bladder repair.
• Evaluation of tissue-engineered constructs and extracellular matrix applications.

Main Results:

• Muscle-derived cells are consistently identified as a promising therapeutic option for future bladder repair.
• Various cell types and delivery methods (injectables, grafts) have been explored for bladder restoration.
• Tissue-engineered constructs require further validation in preclinical and clinical settings.

Conclusions:

• Muscle-derived cell therapy represents a promising avenue for bladder abnormalities.
• Current tissue-engineered constructs need more evidence to demonstrate long-term clinical efficacy.
• Future ideal therapies should address diverse bladder abnormalities effectively.
