文题释义:
脐血单个核细胞:
脐血中的单个核细胞含有大量间质干细胞、未成熟的干/祖细胞、内皮祖细胞等,可作为干细胞移植的重要来源。人脐血干细胞移植可用于治疗多种疾病,如急性心肌梗死、卵巢早衰、血管性痴呆、迟发脑病及各种妇科疾病。
卵巢早衰:是指女性在未满40岁,由于卵巢功能衰竭而导闭经、雌激素分泌下降、促性腺激素升高、不孕、围绝经期综合征的一种多病因疾病。

 

摘要
背景:
干细胞移植成为近年来成为治疗卵巢早衰的热点之一;脐血中的单个核细胞含有大量间质干细胞、未成熟的干/祖细胞、内皮祖细胞等,可作为干细胞移植的重要来源。
目的:观察人脐血单个核细胞移植对裸鼠放射性卵巢早衰的治疗作用。
方法:将120只雌性BALB/C裸鼠随机分为4组,空白对照组不进行任何干预;模型组、静脉移植组、原位移植组进行60Coγ射线照射,0.5 Gy/d,持续30 d,建立卵巢早衰模型;造模成功后,模型组双侧卵巢注入10 µL DMEM,静脉移植组尾静脉注射10 µL人脐血单个核细胞(1×1013 L-1),原位移植组在双侧卵巢注入10 µL人脐血单个核细胞(1×1013 L-1)。细胞移植30 d后,检测各组血清中雌二醇、卵泡激素、黄体生成素、抑制素B及血管内皮生长因子水平,病理观察裸鼠卵巢组织细胞凋亡及静脉移植组细胞存活情况。
结果与结论:①血清指标检测结果:与空白对照组比较,模型组雌二醇、抑制素B、血管内皮生长因子水平降低(P < 0.01),卵泡激素、黄体生成素水平升高(P < 0.01)。与模型组比较,原位移植组雌二醇、抑制素B、血管内皮生长因子水平升高(P < 0.01),卵泡激素、黄体生成素水平降低(P < 0.01);静脉移植组卵泡激素、黄体生成素水平降低(P < 0.05,P < 0.01);②细胞凋亡:与模型组比较,静脉移植组、原位移植组可有效减少颗粒细胞的凋亡(P < 0.05);③细胞存活:人脐血单个核细胞移植后可在裸鼠卵巢中存活;④结果表明:人脐血单个核细胞移植治疗裸鼠卵巢早衰,可调节内分泌水平,抑制卵巢细胞凋亡。

Abstract:

BACKGROUND: Stem cell transplantation, in recent years, has become a preferred treatment for premature ovarian failure. Umbilical cord blood mononuclear cells containing a large number of mesenchymal stem cells, immature stem/progenitor cells, and endothelial progenitor cells can be used as an important source of stem cell transplantation.
OBJECTIVE: To study the therapeutic efficacy of human umbilical cord blood mononuclear cell transplantation on radioactive premature ovarian failure in nude mice.
METHODS: 120 female BALB/C nude mice were randomly divided into four groups: blank control group without any intervention; model group, intravenous transplantation group, and in situ transplantation group exposed to 60Co γ rays, 0.5 Gry per day, for 30 days. After 30 days, premature ovarian failure models were made in the latter three groups. Then, nude mice in the latter three groups were given bilateral ovary injection of 10 µL DMEM, tail vein injection of 10 µL human umbilical cord blood mononuclear cells (1×1013/L), and bilateral ovary injection of 10 µL human umbilical cord blood mononuclear cells (1×1013/L), respectively. Thirty days after cell transplantation, serum levels of estradiol, follicle hormone, luteinizing hormone, inhibin B and vascular endothelial growth factor were detected, cell apoptosis in the ovary tissue and cell survival were observed pathologically.
RESULTS AND CONCLUSION: After modeling, the serum levels of estradiol, inhibin B and vascular endothelial growth factor were significantly reduced (P < 0.01), while follicle hormone and luteinizing hormone levels increased (P < 0.01). After transplantation, these indexes were all improved in the in situ transplantation group (P < 0.01), and reduced follicle hormone and luteinizing hormone levels were visible in the intravenous transplantation group (P< 0.05,P < 0.01). Compared with the model group, in situ transplantation and intravenous injection of human umbilical cord blood mononuclear cells could effectively reduce cell apoptosis in the ovary tissue (P < 0.05), and transplanted cells were able to survive in the ovary of nude mice. All these findings show human umbilical cord blood mononuclear cell transplantation do have curative effects on premature ovarian failure in nude mice through the inhibition of apoptosis and the regulation of hormone secretion.
