目的:研究胃良恶性病变组织中PSCA和Oct-4的表达及其临床意义。方法:58例胃癌、20例癌旁组织、36例淋巴结转移灶及80例不同类型胃良性病变组织常规制作石蜡包埋切片,PSCA和Oct-4染色方法均为EnVision免疫组织化学法,比较其在不同病理类... 目的:研究胃良恶性病变组织中PSCA和Oct-4的表达及其临床意义。方法:58例胃癌、20例癌旁组织、36例淋巴结转移灶及80例不同类型胃良性病变组织常规制作石蜡包埋切片,PSCA和Oct-4染色方法均为EnVision免疫组织化学法,比较其在不同病理类型中的表达情况。结果:胃癌病例PSCA,Oct-4阳性率明显高于癌旁组织及不同类型胃良性病例(P<0.05或P<0.01),PSCA和Oct-4阳性表达癌旁组织和良性病例均呈不同程度不典型增生;淋巴结转移灶与相应原发灶比较,两者阳性率无明显差异(P>0.05);浸润深度T1+T2、无淋巴结转移、淋巴结转移N1站及无远处转移病例PSCA和Oct-4表达阳性率明显低于浸润深度T3+T4、淋巴结转移、淋巴结转移N2+N3站及远处转移病例(P<0.05或P<0.01)。结论:PSCA和Oct-4表达与胃癌侵袭能力、淋巴结转移及远处器官转移有密切关系,提示PSCA,Oct-4表达可能是反映胃癌生物学行为和预后的重要标记物。 展开更多

The endometrium is the inner mucosal lining of the uterus that undergoes extensive cyclic growth, regeneration, differentiation, and shedding throughout the menstrual cycle in response to steroid hormones. It repeatedly undergoes approximately 450 cycles of degeneration and regeneration in a woman's lifetime. Endometrial abnormalities can be associated with repeated embryo implantation failure, recurrent spontaneous abortion, and other physiological features responsible for female infertility. This significant regenerative capacity may occur as a result of tissue-resident stem cell populations within the endometrium. Indeed, the existence of endometrial stem cells was only observed in humans and rodents through several isolation and characterization methods in the last few years. Although endometrial stem cells share various biological characteristics with other types of mesenchymal stem cells, they also show some differences in phenotype, self-renewal, and multilineage differentiation potential. Extensive studies over many years on endometrial stem cells will provide new insights into the physiology and mechanisms underlying various gynaecological diseases related to endometrial abnormalities such as female infertility, endometriosis, and endometrial cancer. Here we summarized recent studies about cellular origins and biological characteristics of endometrial stem cells. We also reviewed various recent studies to improve our understanding of their physiological roles. Many preclinical studies on their potential therapeutic applications to various endometrial diseases that could lead to reproductive dysfunction were also reviewed. 展开更多
