| Popis: | Purpose: Owing to the safety and cost effectiveness of conditioned medium (CM), its therapeutic effects have attracted significant attention from many researchers. To date, numerous studies have been conducted on CM; however, little has been done with regard to erectile dysfunction (ED). In this research, the potential of human mesenchymal stem cell-derived CM (MSC-CM) for the treatment of ED was investigated. Materials and Methods: A high concentration of MSC-CM was prepared through 3D spheroid culturing with bone marrowderived MSCs and cut-off filtering. The composition of CM was analyzed using biochemical assays, and the effect of the preparation process on the quality of CM was investigated. The therapeutic effects of MSC-CM were evaluated through animal studies using a cavernous nerve (CN) injury rat model. Results: 3D spheroid culturing afforded a 278-fold increase in the total protein content of CM, as compared to that from 2D cultures; the protein concentration increased by 19 times on increasing the centrifugation time for cut-off filtering. Biochemical assays indicated that the CM contains various types of angiogenic, neurotrophic, and anti-inflammatory factors. Histological assay results showed that MSC-CM has angio- and neuro-trophic effect in a CN injury rat model in vivo, and these therapeutic effects appear in a dose-dependent manner. Conclusions: The experimental results confirmed the therapeutic effect of MSC-CM in healing damaged cavernosal tissue and restoring erectile function. These results successfully demonstrated that MSC-CM has significant potential for the treatment of ED. |
