    • 摘要: 一、造血干细胞造血干细胞是一群具有自我更新、增殖、分化能力的细胞,它可以分化为各类造血祖细胞,并在造血因子的调控下逐级分化发育为各类成熟的血细胞,如白细胞、红细胞、血小板等。二、造血干细胞移植造血干细胞移植,是患者先接受超大剂量放疗或化疗,以清除体内的肿瘤细胞、异常克隆细胞,同时破坏了自身的免疫系统,然后再回输采自自身或他人的造血干细胞,重建患者的造血功能和免疫功能,达到治疗某些疾病的目的。

    • 摘要: 目的:探讨X射线全身照射后小鼠骨髓造血干/祖细胞(HSCs/HPCs)损伤和其中CD47表达水平的变化,初步阐明CD47在HSCs/HPCs电离辐射损伤中发挥的作用.方法:将C57BL/6小鼠分为未照射组和照射组,其中照射组分为照射后18 h组、5 d组、11 d组和6周组,每组5只.除未照射组小鼠外,其他小鼠均一次性给予3.0或9.0 Gy X射线全身照射.在照射后相应时间点处死小鼠,流式细胞术检测各组小鼠骨髓HSCs与HPCs的百分率.检测照射后各时间点各组小鼠HSCs和HPCs中CD47表达水平.结果:未照射组小鼠HSCs中CD47表达水平高于骨髓成熟造血系细胞1倍以上(P0.05);HPCs占lineage-negative(lin-)细胞百分率或占全骨髓细胞百分率降低(P0.05);照射后18 h组小鼠HSCs占lin-细胞百分率升高(P<0.01),照射后11 d组小鼠HSCs占全骨髓细胞百分率降低(P<0.01).照射后18 h组小鼠HPCs中CD47低表达亚群的百分率明显低于CD47高表达亚群(P<0.01).照射后5 d组、照射后11 d组和照射组后6周组小鼠HPCs中CD47低表达亚群的百分率与CD47高表达亚群的百分率相近.结论:全身电离辐射造成了小鼠骨髓组织损伤,在骨髓细胞中HSCs/HPCs百分率降低,其机制可能与照射后HSCs中CD47表达一过性升高有关联.

    • 摘要: 目的:探索体外诱导小鼠胚胎干细胞(mESC)产生具有T淋巴谱系潜能造血祖细胞的关键步骤和操作技巧,进一步明晰及优化诱导策略,提高功能性血液细胞的体外再生效率.方法:将Runx1和Hoxa9串联重组质粒转染mESC产生iR9-mESC,体外依次诱导可先后产生拟胚体(EB)、诱导性生血内皮细胞(iHEC)、诱导性造血祖细胞(iHPC),随后移植免疫缺陷鼠可检测到受体小鼠中枢和周围淋巴器官中供体来源的T淋巴细胞.其中,在体外培养mESC,电转获得同源重组iR9-mESC,诱导分化形成EB、iHEC及其分选、流式检测和移植等步骤设置不同操作方法对照组.结果:体外培养iR9-mESC时,培养在小鼠胚胎成纤维细胞上比在明胶上更能维持mESC的多能性状态;电转时细胞量为1.2×106能保证电转后培养过程中单个克隆不融合,便于筛选鉴定目的克隆;用巴氏吸管轻柔吹打收集EB保证球状EB的完整性,可以提高诱导分化过程中形成iHEC的比例;分选前免疫磁珠富集CD31+细胞,能提高目的细胞纯度,缩短分选时间,增加细胞活性;尾静脉移植可增加移植成功率和移植细胞数目的准确性.结论:mESC体外诱导分化产生T谱系潜能的造血祖细胞过程中,细胞培养浓度、操作方法细节、工具的使用、分选和移植方法的选择都会影响诱导过程中iHEC和造血祖细胞的含量和谱系特异性,需要针对各分化步骤和时间节点精准操作.

    • 摘要: 目的 探讨异位子宫内膜组织自然杀伤细胞和造血祖细胞(HPCs)对子宫内膜异位症(EMs)合并不孕术后妊娠结局的影响.方法 选择116例EMs合并不孕症患者作为研究对象,采集患者异位子宫内膜组织和外周血,分离异位子宫内膜组织和外周血单个核细胞,采用流式细胞术检测子宫自然杀伤细胞(uNKs)和外周循环自然杀伤细胞(pbNKs)表型,同时检测异位子宫内膜组织和外周血HPCs比例,分析异位子宫内膜组织HPCs与妊娠结局的关系.结果 116例患者中,50例(43.1%)于术后自然妊娠(自然妊娠组),66例(56.9%)于术后行辅助生殖技术(ART).66例行ART的EMs合并不孕症患者最终妊娠(辅助妊娠组)46例(69.7%),未妊娠(未妊娠组)20例(30.3%).uNKs主要表型为CD56bright CD16-,pbNKs主要表型为CD56dimCD16+;未妊娠组、辅助妊娠组和自然妊娠组CD56brightCD16-和CD56dimCD16+的uNKs细胞和pbNKs细胞比例差异均无统计学意义(均P>0.05).辅助妊娠组和自然妊娠组异位内膜组织CD34+ HPCs比例明显高于未妊娠组,差异具有统计学意义(P<0.05);但3组外周血HPCs比例差异无统计学意义(均P>0.05).异位子宫内膜组织HPCs细胞比例预测ART妊娠的曲线下面积(AUC)为0.889(95% CI:0.788~0.953),预测EMs患者术后总体妊娠的AUC为0.821(95%CI:0.739~~0.886).结论 异位子宫内膜组织HPCs细胞比例在EMs术后成功妊娠和未妊娠的MEs患者中存在显著差异,有望成为预测EMs术后妊娠结局的预测指标之一.

    • 摘要: 造血干细胞(hematopoietic stem cell,HSC) 一直被认为处于造血级联的顶端,通过维持自身的自我更新并逐级向下分化成熟,为机体源源不断地提供各种成熟的血细胞.基于HSC移植后分化成熟的变化规律为主要技术方法的研究表明,HSC维持着整个造血系统的稳定,并且在分化发育过程中存在多种不同的模型.然而,从根本上来讲这些研究结果反映的是HSC应对外界压力的应激反应,与正常稳态情况下HSC对于整个造血系统的维持作用并不相同.而最新的一系列利用不同的实验模型对造血祖细胞(hematopoietic progenitor cell,HPC)在造血稳态维持中的作用进行了研究,发现HPC才是造血稳态维持的“主力军”.本文将对目前存在争议的关于HSC和HPC在稳态造血系统维持中作用的最新研究进展作一评述.

    • 摘要: 目的:研究吲哚-3-甲醇(I3C)对小鼠骨髓造血细胞辐射损伤的保护作用及机制。方法(1)密度梯度离心法获得CD45.1亚型C57BL/6J小鼠骨髓有核细胞,经0 mol/L、10-8 mol/L~10-3 mol/L I3C处理后,接受不同剂量(0 Gy、1 Gy、4 Gy)的137Csγ-射线照射;继续培养18 h后采用生物发光法检测细胞活力。(2)设空白对照组和10-6 mol/L I3C组,经上述3种剂量射线照射后,接种于甲基纤维素半固体培养基中培养7 d,观察骨髓粒-单核巨噬细胞集落(CFU-GM)形成情况。(3)取24只CD45.2亚型小鼠接受8 Gy 137Csγ-射线照射作为受体,CD45.1亚型小鼠骨髓有核细胞(供体)设空白对照组、4 Gy照射组和4 Gy照射+10-6 mol/L I3C组。将供体与竞争者(CD45.2亚型)骨髓细胞混和后,接种于受体小鼠体内(每组8只),流式细胞术检测受体小鼠外周血细胞中供体来源的细胞比例。(4)细胞设空白对照组、10-6 mol/L I3C组、1 Gy照射组和1 Gy照射+10-6 mol/L I3C组。培养24 h后收集细胞,提取蛋白后Western blot法检测各组核因子NF-E2相关因子(Nrf2)、血红素加氧酶(HO)-1表达。结果(1)I3C浓度>10-4 mol/L时出现明显的细胞毒性作用(P>0.05);相同剂量射线照射下,10-7~10-6 mol/L I3C可减轻射线对细胞的损伤;因此选取10-6 mol/L为本研究I3C的实验浓度。(2)相同剂量射线照射下,10-6 mol/L I3C组CFU-GM形成数量较空白对照组明显升高(P<0.05)。(3)流式细胞结果显示,4 Gy照射组细胞移植后,受体小鼠外周血中供体细胞比例较对照组明显降低(P<0.05),而10-6 mol/L I3C预处理的供体小鼠细胞移植后,受体小鼠中供体细胞比例较4 Gy照射组升高(P<0.05)。(4)Western blot结果显示,1 Gy照射+10-6 mol/L I3C组Nrf2和HO-1蛋白表达水平明显高于其他3组(P<0.05)。结论 I3C可以减轻辐射引起的小鼠造血细胞损伤和功能下降,其机制可能与激活Nrf2/HO-1通路有关。%Objective To investigate the protective effect of indole-3-carbinol (I3C) on radiation-induced mouse bone marrow hematopoietic cell injury and the involved mechanisms. Methods (1) The bone marrow nuclear cells (BMNCs) from CD45.1 subtype of C57BL/6J mice were collected by a density gradient centrifugation method. The BMNCs were pretreated with a series doses of I3C (0 mol/L, 10-8 mol/L-10-3 mol/L) and then exposed with radiation of 137Csγ-ray (doses of irradiation were 0 Gy, 1 Gy and 4 Gy). After 18-hour culturing, the bioluminescence method was used to detect the cell viability. (2) These cells were divided into control group and 10-6 mol/L I3C group. Both groups were received the irradiation (0 Gy, 1 Gy and 4 Gy) and inoculated into the methylcellulose semi-solid culture medium to incubate 7 days, the colony forming unit-granulocyte monocytes (CFU-GM) were observed. (3) Twenty-four CD45.2 subtype mice used as the receptor were exposed with 8 Gy radiation. The CD45.1 BMNCs were divided into control group, 4 Gy irradiation group, 4 Gy irradiation and 10-6 mol/L I3C group. Donor cells were harvested from C57BL/6J (CD45.1) mice after they received various treatments, and were then mixed with competitive BMNCs from C57BL/6J (CD45.2) mice. The mixed cells were transplanted into recipient mice (8 mice/group). Flow cytometry was used to analyze the proportion of donor cells in peripheral blood of receptor. (4) The cells were divided into control group, 10-6 mol/L I3C group, 1 Gy irradiation group, 1 Gy irradiation with 10-6 mol/L I3C group. After 24-hour culturing, Western blot assay was used to detect the expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and hemeoxygenase-1 (HO-1). Results (1) I3C showed a significant cytotoxic effect on the BMNCs when its concentration was above 10-4 mol/L. 10-7-10-6 mol/L I3C could reduce the radiation injury of BMNCs under the same dose of irradiation. Therefore, 10-6 mol/L I3C was chosen for subsequent experiments. (2) The CFU-GM was significantly higher in 10-6 mol/L I3C group than that of control group (P<0.05). (3) Results of flow cytometry showed that the proportion of donor cells in receptor was significantly higher in 4 Gy irradiation group than that of control group, which decreased the engraftment capability of irradiated HSCs (P<0.05), although the engraftment capability of irradiated HSCs improved after 10-6 mol/L I3C treatment. (4) I3C significantly enhanced the increased protein expression of Nrf2 and HO-1 caused by radiation (P<0.05). Conclusion I3C has a protective effect on hematopoietic cells following radiation-induced injury, which may be related with activating the Nrf2/HO-1 signal pathway.

Methods Seventy-two C57BL/6 mice were randomly divided into control group and irradiated groups (2, 4 and 6 Csγ-ray irradiation, n=18 for each group). Mice of control group received sham irradiation, and the rest accepted 2, 4 and 6 Gy137Csγtotal body irradiation, respectively. After 14-day, 35-day and 56-day irradiation, the peripheral blood samples were collected by balls enucleation. The number of bone marrow nuclear cells, hematopoietic stem and progenitor cells were counted. Results The peripheral blood of irradiated mice showed significant changes in the number of white blood cells (WBC), red blood cells (RBC), platelets (PLT) and hemoglobin (HGB) in a dose-response relationship. Compared with the control group, the numbers of BMNCs and hematopoietic progenitor cells (HPCs) were significantly lower in irradiated group. At 35 d and 56 d after 6 Gy irradiation the numbers of BMNCs and HPCs were significantly lower than those of control group (P<0.05). There were no significant differences in numbers of BMNCs and HPCs between irradiated groups (2 and 4 Gy) and control group. The number of bone marrow hematopoietic stem cells (HSCs) was significantly lower in irradiated group than that in control group after 14-d and 56-d irradiation (P<0.05). Conclusion 137Csγ-ray irradiation has some damage in mouse hematopoietic system. The damage caused by radiation is persistent to hematopoietic stem cells.
