    • 摘要: 2021年1月-2021年6月,我有幸在日本国立成育医疗研究中心(National Center for Child Health and Development,NCCHD)的器官移植中心学习。NCCHD器官移植中心在国际知名的移植专家笠原群生(Mureo Kasahara)教授及阪本靖介(Seisuke Sakamoto)教授的带领下开展儿童肝脏移植、肾脏移植、小肠移植及肝细胞移植。经过这6个月的学习,对于儿童器官移植的体会有所加深。因此,将我的学习见闻及体会与大家分享。

    • 摘要: 目的:探讨巨噬细胞在Fah-/-小鼠肝损伤过程中的作用以及对肝细胞移植效率的影响.方法:观察Fah-/-小鼠撤药后肝损伤过程中巨噬细胞的活化情况,并采用脂质体将巨噬细胞清除后,用脾脏注射的方法将同品系野生型小鼠的成熟肝细胞移植入Fah-/-小鼠体内,评价肝再生效率以及病理学的变化.同时体外分离小鼠骨髓巨噬细胞,将其与原代肝细胞共同回输入Fah-/-小鼠体内,观察细胞再植的效率以及小鼠肝功能的影响.结果:H&E染色与免疫组化染色显示,在撤除药物NTBC[2-(2-硝基-4-三氟甲基苯甲酰基)-环己烷-1,3-二酮]后造成的肝损伤过程中,F a h-/-小鼠肝脏内伴随着内源肝细胞的损伤与巨噬细胞的增殖;采用脂质体对巨噬细胞清除的效率约为50%;清除巨噬细胞后进行原代细胞移植发现在细胞移植第4周,清除巨噬细胞组进行扩增的细胞克隆数目与大小均多于对照组;将小鼠巨噬细胞与原代肝细胞按1:5比例同时回输入Fah-/-小鼠体内,免疫组化染色显示巨噬细胞与原代肝细胞混合注入后肝细胞再植效率降低,且肝损伤较对照组更为严重.结论:巨噬细胞会阻碍Fah-/-小鼠肝细胞移植过程中细胞的增殖.

    • 摘要: BACKGROUND: Hepatocyte transplantation has achieved some success in animal experiments for the treatment of metabolic diseases and acute liver failure. However, the clinical efficacy of hepatocyte transplantation is unsatisfactory. The difference between the experimental results and the clinical efficacy may be related to the hepatocyte transplantation approach. OBJECTIVE: To evaluate the therapeutic effects of hepatocyte transplantation by the intubation via the intubation of the splenic artery and intrasplenic injection in rats with acute hepatic failure, providing more optimal transplantation approaches and methods. METHODS: Hepatocytes were isolated and cultured by the modified Seglen's method (two-step). Acute hepatic failure was induced by D-gal in Sprague-Dawley rats (provided by the Experimental Animal Center of Chongqing Medical University in China). After 24 hours, an intubation tube was inserted into the splenic artery in 65 rats with acute hepatic failure, which was successful in 60 rats. Then these 60 rat models were randomly divided into three groups (n=20 per group). Intrasplenic injection group received about 2×107 hepatocytes through intrasplenic injection and 0.4 mL of Hank's solution through the splenic artery. Splenic artery group received 0.4 mL of Hank's solution through intrasplenic injection and 2×107 hepatocytes through the splenic artery. Model group received 0.4 mL of Hank's solution through intrasplenic injection and 0.4 mL of Hank's solution through the splenic artery. Survival rate and liver function of the rats was observed within 14 days after transplantation. The distribution of CFDA-SE-labeled hepatocytes transplanted via the splenic artery was observed under fluorescence microscope at 7 days after transplantation, and meanwhile, the distribution and proliferation of transplanted hepatocytes in the spleen were observed using hematoxylin-eosin staining. Synthesis of albumin in the spleen was observed by immunofluorescence staining. RESULTS AND CONCLUSION: (1) 80%-90% hepatocytes survived after isolation. (2) At 14 days after transplantation, the survival rates of rats in the three groups were significantly different: intrasplenic injection group> splenic artery group> model group. (3) The liver function of rats was significantly improved in the intrasplenic injection group and the splenic artery group, especially in the former group. (4) CFDA-SE-labeled hepatocytes (green fluorescence) were scattered in the rat spleen and liver at 7 days after transplantation via the splenic artery. (5) At 14 days after transplantation, immunofluorescent staining of albumin demonstrated some positive cells in the rat spleen in the intrasplenic injection group and splenic artery group. (6) At 7 days after transplantation, transplanted hepatocytes were concentrated and colonized in the red pulp of the spleen. In conclusion, hepatocyte transplantation through catheterization of the splenic artery via carotid route can improve the survival of rats with acute hepatic failure and ameliorate the hepatic function, but intrasplenic injection is significantly superior to the injection via the splenic artery.%背景:肝细胞移植在治疗代谢性疾病和急性肝衰竭的动物实验中取得了一定成功, 然而肝细胞移植的临床疗效却并没有动物实验理想.造成实验模型与临床疗效的差异可能与肝细胞移植途径有一定关系.目的:探讨经颈动脉途径脾动脉插管注射与脾脏直接注射两种方法行肝细胞移植治疗急性肝衰竭大鼠的疗效, 得出更加优化的移植方法.方法:在Seglen改良两步法的基础上稍加改进分离培养肝细胞.采用D-氨基半乳糖诱导大鼠 (重庆医科大学实验动物中心提供) 急性肝衰竭24h后, 65只大鼠经颈动脉途径脾动脉插管, 60只插管成功后随机分为3组:脾脏直接注射组 (n=20) 大鼠经脾脏直接注射约2×107个肝细胞、脾动脉注射0.4m Lhank's液;脾动脉注射组 (n=20) 大鼠经脾脏直接注射0.4 mL Hank's液、脾动脉注射2×107个肝细胞;模型对照组 (n=20) 经脾脏直接注射0.4 mL Hank's液、脾动脉注射0.4 mL Hank's液.移植后14 d内观察各组大鼠的生存率及肝功能变化;移植后7d, 荧光显微镜观察经脾动脉移植肝细胞的体内分布情况, 苏木精-伊红染色观察移植肝细胞在脾内的分布和增殖情况;移植后14 d, 免疫荧光染色观察白蛋白合成情况.结果与结论: (1) 大鼠肝细胞分离存活率达80%-90%; (2) 3组大鼠生存率的比较差异有显著性意义, 脾脏直接注射组14 d存活率显著高于脾动脉注射组, 脾动脉注射组14 d存活率高于模型对照组; (3) 脾脏直接注射组、脾动脉注射组大鼠肝功能均明显改善, 尤其以脾脏直接注射组最为显著; (4) CFDA-SE荧光标记的肝细胞经脾动脉移植7 d后, 受体大鼠脾脏和肝脏可以看到散在绿色荧光分布; (5) 移植14 d后, 脾脏直接注射组、脾动脉注射组脾脏内有肝细胞白蛋白绿色荧光信号; (6) 移植7d后, 脾脏直接注射组、脾动脉注射组肝细胞在脾脏红髓中簇集在一起并定植下来; (7) 结果表明, 经大鼠颈动脉途径脾动脉插管移植肝细胞能提高急性肝衰竭大鼠的存活率和改善其肝功能;脾脏直接注射法优于脾动脉途径注射法.

    • 摘要: Objective To investigate the inducing effect and mechanism of semimature dendritic cell ( smDCs ) on transplantation tolerance of hepatocytes differentiated from mouse embryonic stem cells (ESCs), and to study the connections between smDCs and regulatory dendritic cells (regDCs).Methods ESCs of 129 mouse labelled green fluorescent protein ( GFP) were induced to hepatocytes by using previous methods.Meanwhile, bone marrow mononuclear cells of 129 mouse were induced to smDCs and regDCs.Moreover , the hepatocytes differentiated from 129 mouse ESCs were transplanted into liver of BALB/c mouse 3 days after infusing smDCs and regDCs suspension of 129 mouse into BALB/c mouse by tail vein respectively.After that, the growth status and survival time of transplanted cells in the recipient and infiltration of lymphocytes in transplant sites were observed.Furthermore, Foxp3 expression of peripheral blood CD4+T cells was also tested.Results In the control group , the transplanted cells in liver of BALB/c mouse survived only about 1 week.In contrast, the transplanted cells of smDC groups and regDCs groups survived about 4 weeks and the transplant sites of smDC groups also had less CD 3 +T cells.The morphology of smDCs were similar with regDCs.The expression of MHC-Ⅱ, CD40, CD80 and CD86 on smDCs and regDCs were moderate.Moreover, the Foxp3 expression of peripheral blood CD 4+T cells in smDC groups was higher than that in the control groups , from 1.11% up to 5.38%.The Foxp3 expression in regDC groups rose to 3.87%.Conclusion The smDCs could induce transplantation tolerance of hepatocytes differentiated from 129 mouse ESCs in the recipient.The mechanism was associated with high level of Foxp3 +Tregs, which could be increased by means of smDCs appropriate expression of MHC -Ⅱ, CD40, CD80 and CD86.The smDCs and regDCs were the same type of tolerance dendritic cells.%目的:观察半成熟树突状细胞( smDCs )在小鼠胚胎干细胞( ESCs )来源的肝细胞移植中诱导免疫耐受的作用及机制,并分析smDCs与调节性树突状细胞( regDCs )之间的关系。方法将绿色荧光蛋白( GFP)标记的129系小鼠ESCs按前期方法向肝细胞诱导分化,同时诱导129系小鼠骨髓单核细胞向smDCs和regDCs分化。将smDCs、regDCs分别预先输入BALB/c小鼠体内,3 d后再将ESCs分化的肝细胞移植入BALB/c小鼠肝实质内。观察移植细胞生存时间、生长状况、局部免疫反应情况;检测分析受体血CD4+T细胞Foxp3表达情况等。结果对照组小鼠肝实质内移植细胞仅生存1周,smDCs组与regDCs组生存时间可达4周,移植部位CD3+T细胞浸润较对照组明显减轻;smDCs与regDCs在形态和表型方面相似,二者均中度表达MHC-Ⅱ、CD40、CD80、CD86;smDCs组受体小鼠外周血CD4+T细胞Foxp3表达量明显升高由1.11%上升至5.38%;regDCs组Foxp3表达量亦有所升高达3.87%。结论 smDCs能诱导ESCs源性肝细胞移植耐受,其机制可能与Foxp3+Tregs产生相关。 smDCs与regDCs作用类似,且均中度表达MHC-Ⅱ、CD40等,推测为同一类型的耐受性树突状细胞。
