Most researchers reported that neuroendocrine cell's were the results of stem cell's multi-directional differentiation, like epithelial cell, which is originated from endoderm multipotential stem cells.

多数研究认为，神经内分泌（neuroendocrine，NE）细胞和上皮细胞均来自内胚层多潜能干细胞，是肿瘤发生过程中干细胞多向分化的结果。

BACKGROUND: Oxygen-derived free radicals are produced during non-enzymatic glycosylation of diabetic protein and accompanied with decrease in nitrogen monoxide synthesis so as to cause the calcium increase in cell,evacuation of pykno-granule and apoptosis induced by activating endoenzyme.

背景：糖尿病蛋白质非酶糖化过程中可产生大量的氧自由基，同时伴有一氧化氮合成下降，致使细胞内钙增加，胞内致密颗粒排空、激活胞内酶而启动细胞凋亡的发生。

ABSTRACT: Objective To detect expression of epidermal growth factor receptor variant Ⅲ in human suprarenal epithelioma to explore its relation with the genesis and development of suprarenal epithelioma.

Many human suprarenal epithelioma tissues express EGFRvⅢ. EGFRvⅢ may play certain role in the genesis and development of human suprarenal epithelioma.

EGFRvIII在肾透明细胞癌组织中存在高表达，与肾透明细胞癌的发生、发展有一定关系。

To date,it has been documented after transfusion of unirradiated blood components to at least 87 patients:in patients with severe combined immunodeficiency,thymic hypoplasia,and Wiskott Aldrich syndrome premature newborns and those with erythroblastosis fetalis; patients with hematologic malignancies including Hodgkin\'s and non-Hodgkin\'s lymphomas,acute myelocytic and lymphoblastic leukemias,chronic lymphocytic leukemia,and aplastic patients with solid tumors including neuroblastomas, glioblastoma,rhabdomyosarcoma,cervical carcinoma,small cell lung cancer,and germ cell tumor;patients after cardiac surgery and cholecystectomp-60;and in an apparently healthy 22-year-old woman.

目前为止，输注未辐照血液成分后，至少引起了87例TA-GVHD的发生，主要见于以下病人：严重的免疫缺陷病人、胸腺发育不全、Wiskott Aldrich综合症、早产儿、胎儿红细胞增多症、何杰金与非何杰金氏淋巴瘤等恶性血液病人、急性粒细胞性和淋巴细胞性白血病、慢性淋巴细胞性白血病、成神经细胞瘤等实体瘤病人、横纹肌赘瘤、宫劲癌、小细胞肺癌、微细胞瘤、心脏和胆囊手术病人。

In the late of April of the second year, male inflorescences unbound and pollinated. When female inflorescences accepted the pollen grains, ovary development was increased in early May. With the development of either of the two ovule, funiculus, integument and nucellus were differentiated. Embryo sac mother cell came into being and the meiosis begins. Then fuctional megaspore developed into matured embryo sac that contain eight nucleuses. In the end of May, double fertilization generated.

次年，4月下旬，雄花序解螺旋散粉，雌花序开花授粉；5月上旬，雌花序授粉后，迅速增长，子房膨大，两个胚珠分化出珠柄、珠被和珠心，珠心中产生孢原细胞；5月中下旬，大孢子母细胞形成并减数分裂，功能性大孢子形成成熟的八核胚囊；5月底，发生双受精。

Genes important for male gametogenesis involved in highly con-served landmark events such as meiotic recombination, formation of the synaptonemal complex, sister chromatid cohesion, spermiogenesis during postmeiotic stages, and checkpoints and factors required for the meiotic cell cycle .

精子发生中的重要基因与一系列精子发生过程中阶段性的细胞事件密切相关，例如减数分裂重组、联会丝复合物的形成、姊妹染色体的结合、减数分裂后精子的变态以及减数分裂周期中的关键点和必需因子等。

Female gametogenesis in higher plants undergoes various developmental changes, including the de novo formation of germline cells, the differentiation of the megaspore mother cell, meiosis, megaspore selection, and the development of the embryosac.

高等植物雌配子体的形成涉及孢原细胞和大孢子母细胞的确立与分化、大孢子发生、功能大孢子以及胚囊的形成和发育等多种复杂调控过程。随着当代生物技术及功能基因组学的发展，近年对雌配子体发育的研究已从细胞学描述逐渐过渡到对基因和发育调控分子机理的探索。
