摘要: 睾丸衰老的主要特点为睾酮合成能力以及生精功能逐渐下降,不仅会影响男性生育力,也与衰老相关慢性疾病关系密切。因此,延缓睾丸衰老对于改善中老年男性健康和生活质量至关重要。干细胞是具有强大的自我更新能力和多向分化潜能的细胞群体,近年来,其基础与临床应用研究不断深化,推动了细胞疗法的发展。干细胞移植目前已被用于治疗多种疾病,在衰老与再生医学领域也受到广泛关注。干细胞移植在治疗睾丸衰老中也具有巨大的应用前景。本文将回顾干细胞移植治疗睾丸衰老的相关研究历程与进展,并探讨临床转化面临的瓶颈以及疗效优化策略,以期为睾丸衰老的干细胞疗法研发及临床转化提供新思路。Abstract: Testicular aging is mainly characterized by a gradual decline in the capability of testosterone synthesis and spermatogenesis, which not only affects male fertility, but also correlates with aging-related chronic diseases intimately. Therefore, delaying testicular aging plays a significant role in improving the health and quality of life of middle-aged and elderly men. Stem cells are a cell group with potent self-renewal capability and multi-directional differentiation potential. In recent years, the research of stem cells in basic and clinical application has been carried out in-depth, which has accelerated the development of cell therapy. Currently, stem cell transplantation has been employed to treat multiple diseases, which has captivated widespread attention in the field of aging and regenerative medicine. Stem cell transplantation has demonstrated promising prospects in the treatment of testicular aging. In this article, research profile and progress of stem cell transplantation in the treatment of testicular aging were reviewed, and bottleneck issues encountered in clinical translation and strategies for optimizing clinical efficacy were discussed, aiming to provide novel ideas for the research and development and clinical translation of stem cell therapy for testicular aging.
