文题释义:
脐带间充质干细胞:
是一类发育早期具备全能细胞特点的造血干细胞此外的另一类细胞,具有自我更新、多向分化潜能,细胞能调节机体免疫,而在脊髓损伤、糖尿病足以及免疫性疾病中得到应用。
肺癌化疗:其在肺癌的治疗中发挥不可替代的地位,随着化疗药物的不断发展以及不同药物的联合使用,使得肺癌患者生存期得到进一步延长。但是,化疗药物在杀灭肿瘤、抑制癌细胞增殖的同时对正常组织也会出现不同程度的损害,尤其是对于分裂增殖较快的细胞,导致患者治疗依从性较差,毒副反应发生率较高。

 

摘要
背景:
间充质干细胞具备多向分化潜,能促进细胞植入和免疫调节,研究人脐带间充质干细胞分离鉴定方法及移植后对肺癌小鼠化疗的影响能为肺癌治疗提供新的思路。
目的:观察人脐带间充质干细胞分离、鉴定方法及移植后对肺癌小鼠化疗的影响。
方法:取新鲜的新生儿脐带,利用组织块培养法和酶消化法分离、鉴定人脐带间充质干细胞。将Balb/C裸小鼠肺癌模型20只,随机分为化疗组和人脐带间充质干细胞移植组,两组均给予化疗治疗,人脐带间充质干细胞移植组化疗期间联合移植人脐带间充质干细胞治疗。
结果与结论:①瘤质量、肠黏膜组织形态及血常规指标:与单纯化疗的肺癌模型小鼠相比,人脐带间充质干细胞移植组胃肠道红润、有光泽,肠黏膜光滑、完整,瘤质量和血常规指标稳定(P < 0.05);②结果证实:通过组织块培养法和酶消化法能获得成熟的人脐带间充质干细胞,与化疗联合应用可明显减少胃肠道的损害,稳定外周血象。

Abstract:

BACKGROUND: Mesenchymal stem cells have pluripotent differentiation, and can promote cell engraftment and immune regulation. Therefore, we attempt to use human umbilical cord mesenchymal stem cells as a new source for treatment of lung cancer by exploring cell isolation, identification and transplantation combined with chemotherapy for lung cancer in mice.
OBJECTIVE: To investigate the isolation and identification of human umbilical cord mesenchymal stem cells and its transplantation combined with chemotherapy for lung cancer in mice.
METHODS: Human umbilical cord mesenchymal stem cells were isolated from fresh umbilical cord of newborns and identified using tissue culture and enzyme digestion. Twenty Balb/C nude mouse models of lung cancer were randomly divided into two groups: mice in chemotherapy group were given chemotherapy, and those in combined group given combination of chemotherapy with human umbilical cord mesenchymal stem cell transplantation.
RESULTS AND CONCLUSION: Compared with the chemotherapy group, the gastrointestinal tract was rosy and shiny, intestinal mucosa was smooth and complete, and tumor mass and blood indexes significantly decreased in the combined group (P < 0.05). To conclude, mature human umbilical cord mesenchymal stem cells can be obtained by tissue culture and enzyme digestion, and the cell transplantation combined with chemotherapy can significantly reduce gastrointestinal tract damage and the make peripheral hemogram in a stable level.
