Abstract: Various studies have been widely conducted on conditioned medium for the development of anti-aging preparations, including the utilization of stem cells, which present a promising alternative solution. This narrative review aims to understand the latest developments in various conditioned medium stem cell applications for anti-aging on the skin. A search of the Scopus database yielded publications of interest. The research focused on articles published without restrictions on the year. After finding 68 articles in the search results, they moved on to the checking phase. Upon comprehensive literature review, 23 articles met the inclusion criteria, while 45 articles were deemed ineligible for participation in this research. The results of the review indicate that conditioned medium from various stem cells has demonstrated success in reducing risk factors for skin aging, as proven in various tests. The successful reduction of the risk of skin aging has been established in vitro, in vivo, and in clinical trials. Given the numerous studies on the progress of exploring and utilizing conditioned medium, it is expected to provide a solution to the problem of skin aging.
Keywords: conditioned medium, stem cell, anti-aging, skin aging

Abstract: Pearl oysters have been extensively utilized in pearl production; however, most pearl oyster shells are discarded as industrial waste. In a previous study, we demonstrated that the intraperitoneal administration of pearl oyster shell-derived nacre extract (NE) prevented d-galactose-induced brain and skin aging. In this study, we examined the anti-aging effects of orally administered NE in senescence-accelerated mice (SAMP8). Feeding SAMP8 mice NE prevented the development of aging-related characteristics, such as coarse and dull hair, which are commonly observed in aged mice. Additionally, the NE mitigated muscle aging in SAMP8 mice, such as a decline in grip strength. Histological analysis of skeletal muscle revealed that the NE suppressed the expression of aging markers, cyclin-dependent kinase inhibitor 2A (p16) and cyclin-dependent kinase inhibitor 1 (p21), and increased the expression of sirtuin1 and peroxisome proliferator-activated receptor gamma coactivator 1 (PGC1)- α, which are involved in muscle synthesis. These findings suggest that the oral administration of NE suppresses skeletal muscle aging. Moreover, NE administration suppressed skin aging, including a decline in water content. Interestingly, oral administration of NE significantly extended the lifespan of SAMP8 mice, suggesting that its effectiveness as an anti-aging agent of various tissues including skeletal muscle, skin, and adipose tissue.

多学科协作诊疗模式(MDT)是21世纪以来国内外新出现的最重要的医学模式之一。目的是使传统的个体式、经验式的医疗模式转变为小组协作共同决策的模式,其可以针对特定疾病,整合医疗资源,依托多学科团队,以求能够为患者制定最佳的诊断和治疗方案,并在深入交流的过程中提高各个专科的水平。

一位援疆医生讲述了自己的故事:一天夜里,他接诊了一名遭遇车祸的病人,肝脏破裂,生命垂危。虽经全力抢救,病人终因失血过多而死亡。当医生告诉家属这个坏消息后,家属不仅没有责怪医生,反而向医生道谢,然后要求把切下的破碎肝脏带回去,和死者一起埋葬。丧事办完后,家属又来到医院结清所有费用。此举令这位医生十分感动。从此,每当遇到危重患者,他都没有后顾之忧,总是愿意冒险一搏。
