1Genomics identifies medulloblastoma subgroups that are enriched for specific genetic alterations显示文摘Thompson MC Fuller C Hogg TL Dalton J Finkelstein D Lau CC Chintagumpala M Adesina A Ashley DM KeUie SJ Taylor MD Curran T Gajjar A Gilbertson RJ 2006中国神经肿瘤杂志2006,4,1:17
2人肝癌细胞系P2-HCC的建立及体外诱导分化特性的初步研究显示文摘目的:从人肝细胞癌中分离肝癌细胞并对其体外诱导分化特性进行分析,试图得到有关导致肝癌发生的“癌干细胞”的相关资料。方法:首先将人原发性肝癌组织小块在裸鼠皮下过继接种,然后将生成的肿瘤进行原代培养并得到单层生长的肿瘤细胞系,利用体外诱导实验对其形态及分子表型的变化情况进行观察和分析。结果:所分离获得的细胞系具有肝肿瘤细胞的特征,但也表达某些干细胞的分子标志如c met。体外诱导分化实验提示胰岛素/氢化可的松、二甲亚砜可能具有诱导该细胞向成熟肝细胞方向分化的作用,诱导后的细胞又重新表达葡萄糖6 磷酸酶,白蛋白表达明显升高。结论:人P2 HCC细胞具有强大的增殖能力,体外实验提示其具有一定的向成熟肝细胞分化的潜能。这些细胞的发生与肝癌干细胞及肝细胞的关系尚待进一步研究。朱海英 张朵 谢东甫 王新民 周旭宇 Joseph T Lau 胡以平 2005第二军医大学学报2005,26,3:16
3Update on the applications and limitations of alpha-fetoprotein for hepatocellular carcinoma显示文摘Alpha-fetoprotein(AFP)is an oncofetal glycoprotein that has been used as a tumor marker for hepatocellular carcinoma(HCC)in combination with ultrasound and other imaging modalities.Its utility is limited because of both low sensitivity and specificity,and discrepancies among the different methods of measurements.Moreover,its accuracy varies according to patient characteristics and the AFP cut-off values used.Combination of AFP with novel biomarkers such as AFP-L3,Golgi specific membrane protein(GP73)and des-gamma-carboxyprothrombin significantly improved its accuracy in detecting HCC.Increased AFP level could also signify severity of hepatic destruction and subsequent regeneration and is commonly observed in patients with acute and chronic liver conditions and cirrhosis.Hereditary and other non-hepatic disorders can also cause AFP elevation.Hira Hanif Mukarram Jamat Ali Ammu T Susheela Iman Waheed Khan Maria Alejandra Luna-Cuadros Muzammil Muhammad Khan Daryl Tan-Yeung Lau 2022World Journal of Gastroenterology2022,28,2:9
4人胎肝干细胞在重症联合免疫缺陷小鼠损伤肝脏中的植入显示文摘目的:从孕4.5~6周的人胚胎肝脏中分离培养肝干细胞,并观察其在重症联合免疫缺陷(SCID)小鼠损伤肝脏中的植入.方法:从孕4.5~6周的人胚胎肝脏中分离干细胞并进行体外长期培养,用RT PCR方法检测肝干细胞相关分子标志以及八聚物结合蛋白4(Oct-4)的表达,然后植入经四氯化碳(CCl4)造成急性肝损伤的SCID小鼠体内,在移植后2、l0、17d分别对受体鼠肝脏冰冻切片进行荧光观察和H-E染色.结果:所建立的胎肝细胞系不仅表达二肽水解酶Ⅳ(DPPⅣ)、白蛋白(Alb)、细胞角蛋白(CK)19、γ-谷氨酰转肽酶(γ-GT)、CK18、肝细胞生长因子受体(c-met)、干细胞因子受体(c-kit)等肝干细胞相关标志,还表达干细胞转录因子Oct-4.在细胞移植后2 d,肝脏冰冻切片未见绿色荧光;移植后10 d和17d肝脏冰冻切片见散在的绿色荧光.对同一切片做H-E染色,发现绿色荧光部位为肝板内的多个成熟肝细胞.结论:从人胚胎肝脏中分离的干细胞能够植入SCID小鼠的损伤肝脏.苏娟 李文林 陶欣荣 朱海英 王新民 李建秀 田棣 余宏宇 Joseph T Lau 胡以平 2005第二军医大学学报2005,26,3:4

6小鼠单纯肝切除后再生肝组织内大小核分裂相和卵圆细胞的观察显示文摘目的:探究C57小鼠单纯2/3肝切除后肝组织内与再生和肝干细胞有关的病理形态学变化及其意义。方法:在4个对照组(正常组、假手术组、倒千里光碱组和倒千里光碱2/3肝切除组)的参照下,观察实验组C57小鼠单纯2/3肝切除后不同时间肝脏病理形态变化(核分裂相和卵圆细胞等)和CK19、AFP免疫组化检测情况。结果:单纯2/3肝切除后小鼠均出现不同程度的成熟肝细胞通过大核分裂相分裂增生、轻重不等的小胆管/终末胆管增生反应和个别例中有类似于倒千里光碱肝切除模型组的卵圆细胞增生;尤其还有大小核分裂相分布等一些文献未提及的形态学改变。结论:本研究提出肝流域假说的初步设想:肝内成体干细胞存在于小胆管/终末胆管附近,是肝主质细胞的重要源头;在其向中央静脉方向的流向上产生各级分化程度不同的子代(自卵圆细胞到小肝细胞、成熟肝细胞),沿肝板形成该流域干流;而经由血流到达肝脏的过客性干细胞可不同程度地在不同区段作为该流域的支流汇入干流并转分化为肝系细胞。余宏宇 李文林 谢东甫 张朵 肖承志 孙志勇 何金 孙静 苏娟 李建秀 朱明华 Joseph T Lau 胡以平 2005第二军医大学学报2005,26,3:3
