Abstract (original English)

Umbilical cord-derived mesenchymal stem cells (UC-MSCs) are a clinically attractive regenerative and immunomodulatory platform that combines ethical accessibility, low immunogenicity, rapid expansion, genetic stability, and a potent paracrine secretome. This study aimed to synthesize evidence on safety, efficacy, and translational readiness by conducting a focused PubMed review (2014-2024) restricted to clinical studies and trials, using predefined inclusion and exclusion criteria and structured data extraction. Across indications, UC-MSCs show a consistent safety profile and signals of benefit mediated by tissue repair and immune regulation: in musculoskeletal disease they improve osteoarthritis pain and function and may slow osteonecrosis; in hepatology they sustain gains in decompensated cirrhosis, mitigate acute allograft rejection, and aid recovery from ischemic-type biliary lesions; as induction in renal transplantation they are feasible with early graft benefits; in type 2 diabetes responders improve glycemic control and inflammation, while maternal and obstetric factors can shape intrinsic cell properties; in neurology, studies in cerebral palsy, chronic spinal cord injury, and traumatic optic neuropathy report motor, sensory, and visual improvements; in COVID-19-related acute respiratory distress syndrome (ARDS) trials show better oxygenation, radiological recovery, qu
