文题释义:
人脐带间充质干细胞:
具有较高的分化潜能,在骨、软骨、肌肉、肌腱、韧带、神经、肝、内皮和心肌等组织工程方面具有广阔的临床应用前景。有报道从人脐带中分离出间充质干细胞,其细胞含量、增殖能力优于骨髓间充质干细胞,免疫原性低于骨髓间充质干细胞,并且具有取材方便、无伦理学争议等优点,因此越来越受到研究工作者们的关注。
皮肤溃疡:一般是由创伤、微生物感染、肿瘤、循环障碍和神经功能障碍、免疫功能异常或先天皮肤缺损等引起的局限性皮肤组织缺损。临床上静脉曲张所致溃疡、中小动脉缺血性溃疡难以愈合,往往继发感染,经久不愈,甚至截肢。

 

摘要
背景:
人脐带间充质干细胞对于皮肤溃疡的治疗需进行更多方面的评估。
目的:探讨人脐带间充质干细胞促进小鼠皮肤溃疡愈合的可能性。
方法:取C57小鼠20只,随机分成对照组和实验组,每组10只。用无菌剪刀在小鼠背部建立纵行皮肤创面模型,创面约2.5 cm×2.0 cm大小,深度约5 mm。造模后,实验组创周和创面注射1 mL人脐带间充质干细胞悬液,对照组注射等量生理盐水。每天测量两组小鼠溃疡面积,计算创面愈合率,并于移植0,7,14 d取小鼠皮肤溃疡周围组织,免疫组织化学检测血管内皮生长因子的表达,免疫荧光染色检测抗细胞核抗体MAB1281表达用于评估人脐带间充质干细胞在溃疡周围的残留率。
结果与结论:①实验组溃疡愈合时间短于对照组(P < 0.05);②实验组创面血管内皮生长因子表达量明显高于对照组(P < 0.05);③移植后0 d人脐带间充质干细胞残留最多,随着皮肤溃疡的愈合,人脐带间充质干细胞在溃疡周围残留量逐渐减少;④结果表明,人脐带间充质干细胞在小鼠体内可能通过旁分泌血管内皮生长因子的方式促进局部血管新生,进而促进皮肤溃疡愈合。

Abstract:

BACKGROUND: More assessments are required on the use of human umbilical cord mesenchymal stem cells in the treatment of skin ulcers.
OBJECTIVE: To explore the feasibility of human umbilical cord mesenchymal stem cells to promote skin ulcer healing in mice.
METHODS: Twenty C57 mice were randomized into control and treatment groups (n=10 per group). A longitudinal skin wound model was made on the back of the mouse with sterile scissors. The wound surface was about 2.5 cm×2.0 cm in size and the wound depth was about
5 mm. After modeling, 1 mL of human umbilical cord mesenchymal stem cells was injected into the wound in the treatment group, while the same volume of normal saline was given in the control group. The ulcer area of the two groups was measured every day, and the wound healing rate was calculated. The peri-ulcer tissue was taken at 0, 7, and 14 days after transplantation. The expression of vascular endothelial growth factor was detected by immunohistochemistry. The anti-nuclear antibody MAB1281 was detected by immunofluorescence staining to assess the residual rate of human umbilical cord mesenchymal stem cells around the ulcer.
RESULTS AND CONCLUSION: The skin ulcer in the treatment group healed more quickly than that in the control group (P < 0.05). The expression of vascular endothelial growth factor was higher in the treatment group than the control group (P < 0.05). There were more residual human umbilical cord mesenchymal stem cells at the day of transplantation, while the number of residual cells gradually reduced with the healing of skin ulcer. These findings indicate that human umbilical cord mesenchymal stem cells maybe promote the neovascularization by paracrine approaches, and thus facilitate the healing of skin ulcer in mice.
