Diabetic nephropathy (DN) is considered as one of the most serious complications resulting from diabetes mellitus and end-stage of renal failure globally. Up to 40% of diabetic patients will develop DN. The involvement of mesenchymal stem cells (MSCs) in diabetic renal lesions management has been established in many animal models of DN. The aim is to evaluate the capability of MSCs and their culture medium (CM) to alleviate DN in streptozotocin (STZ)-induced diabetic rat model. Female albino rats were made diabetic and were further categorized into 4 subgroups of 15 each: DN group, DN group received fibroblasts, MSCs group received one dose of 1 × 106 cells of MSCs, and CM group received one dose of 500 μl of CM. In all groups, the treatment was delivered by intravenous injection (IV) into the tail vein. MSCs insinuated themselves into the injured kidney as detected by CD44 expression. Biochemical and histological results showed that MSCs and/or CM effectively attenuated DN manifestations in rat model through their possible anti-inflammatory (tumor necrosis factor-α and transforming growth factor-β1 were decreased), anti-apoptotic (Bcl2 was increased while Bax and caspases were decreased), and anti-oxidant role (malondialdehyde was decreased while glutathione and catalase were increased). These results provide a potential therapeutic tool for DN management through the administration of the CM from MSCs that ameliorates the effects of diabetes. It is also possible to treat DN using CM alone thus avoiding cell transplantation.

间充质干细胞及其培养基在减轻糖尿病肾病大鼠肾损伤中的作用

糖尿病肾病(DN)被认为是全球范围内由糖尿病和肾功能衰竭终末期引起的最严重的并发症之一。多达 40% 的糖尿病患者会发展为 DN。间充质干细胞 (MSCs) 在糖尿病肾脏病变管理中的参与已在许多 DN 动物模型中得到证实。目的是评估 MSCs 及其培养基 (CM) 在链脲佐菌素 (STZ) 诱导的糖尿病大鼠模型中减轻 DN 的能力。将雌性白化大鼠制成糖尿病并进一步分为 4 个亚组,每组 15 只:DN 组,DN 组接受成纤维细胞,MSCs 组接受一剂 1×106 个 MSCs 细胞,CM 组接受一剂 500 μl CM。在所有组中,治疗均通过尾静脉静脉注射 (IV) 进行。通过 CD44 表达检测到,MSCs 将自身潜入受伤的肾脏中。生化和组织学结果表明,MSCs 和/或 CM 通过其可能的抗炎作用(降低肿瘤坏死因子-α 和转化生长因子-β1)、抗凋亡(Bcl2 增加,而 Bax 和caspase 减少)和抗氧化作用(丙二醛减少而谷胱甘肽和过氧化氢酶增加)。这些结果为 DN 管理提供了一种潜在的治疗工具,通过施用来自 MSC 的 CM 来改善糖尿病的影响。也可以单独使用 CM 治疗 DN,从而避免细胞移植。生化和组织学结果表明,MSCs 和/或 CM 通过其可能的抗炎作用(降低肿瘤坏死因子-α 和转化生长因子-β1)、抗凋亡(Bcl2 增加,而 Bax 和caspase 减少)和抗氧化作用(丙二醛减少,而谷胱甘肽和过氧化氢酶增加)。这些结果为 DN 管理提供了一种潜在的治疗工具,通过施用来自 MSC 的 CM 来改善糖尿病的影响。也可以单独使用 CM 治疗 DN,从而避免细胞移植。生化和组织学结果表明,MSCs 和/或 CM 通过其可能的抗炎作用(降低肿瘤坏死因子-α 和转化生长因子-β1)、抗凋亡(Bcl2 增加,而 Bax 和caspase 减少)和抗氧化作用(丙二醛减少,而谷胱甘肽和过氧化氢酶增加)。这些结果为 DN 管理提供了一种潜在的治疗工具,通过施用来自 MSC 的 CM 来改善糖尿病的影响。也可以单独使用 CM 治疗 DN,从而避免细胞移植。抗细胞凋亡(Bcl2 增加而 Bax 和半胱天冬酶减少)和抗氧化作用(丙二醛减少而谷胱甘肽和过氧化氢酶增加)。这些结果为 DN 管理提供了一种潜在的治疗工具,通过施用来自 MSC 的 CM 来改善糖尿病的影响。也可以单独使用 CM 治疗 DN,从而避免细胞移植。抗细胞凋亡(Bcl2 增加而 Bax 和半胱天冬酶减少)和抗氧化作用(丙二醛减少而谷胱甘肽和过氧化氢酶增加)。这些结果为 DN 管理提供了一种潜在的治疗工具,通过施用来自 MSC 的 CM 来改善糖尿病的影响。也可以单独使用 CM 治疗 DN,从而避免细胞移植。
