A Preliminary Study on Evaluating Reparative Regeneration Potential of Human Amniotic Fluid Stem Cells Spheres in Stress Urinary Incontinence Rats
A preliminary rat study compared human amniotic-fluid stem cells delivered as single cells versus spheres after pudendal-nerve injury. Approximately 150-micrometer spheres formed over 16-20 hours produced better leak-point pressure and intercontraction intervals than single cells.
