Abstract (original English)

Background: We aimed to examine the therapeutic efficacy of exosome-enriched conditioned media (CM), known for its high concentration of extracellular vesicles (EVs), in comparision with mesenchymal stromal/stem cells (MSCs) in treating non-obstructive azoospermia. Materials and methods In this experimental study, we used adipose tissue-derived MSCs (AT-MSCs), bone marrowderived MSCs (BM-MSCs), and BMCM containing EVs to treat busulfan-induced azoospermia in animal models. The study included thirty adult male Balb/C mice and two female enhanced green fluorescent protein-positive (eGFP+/+) Balb/C mice for experimental groups and stem cell culturing. Groups consisted of an intact control, an azoospermia group, an AT-MSC therapy group, a BM-MSC therapy group, a BMCM therapy group, and a spontaneous healing group. Testes were removed from all mice, and histomorphometry and flow cytometry analyses were performed 60 days post-treatment. Additionally, protein structure extraction, protein-protein docking analysis, and data visualization were conducted. Results Histomorphometry and flow cytometry showed that most seminiferous tubules in the therapy groups exhibited normal morphology and restored spermatogenesis, unlike the azoospermia group. In silico protein docking analysis revealed that exosome factors in BM-MSCs positively impacted spermatogenesis. The BM-MSC and BMCM therapy group
