Cell proliferation and viability were assayed 48h after transfection, and MDA-7 demonstrated selective inhibition of tumor cell growth, inhibitory rates of A549, Hela and HepG2 cell lines were 25%, 20% and 19%, respectively, but had no significant effect on human fetal kidney derived 293 cell line. Hela cell was screened by G418 for 2 weeks after pcDNA3-MDA-7 and monolayer colony was counted, its monolayer colony formation was 30% of cells transfected with pcDNA3. 0 vector. CMV-driven MDA-7 adenovirus vector was constructed. 293 showed no significant apoptosis during adenovirus packaging and the unpurified adenovirus titer was about 1×10〓pfu/ml. Cos 7, A549, Hela, HepG2 and Hep3B cell was infected with Ad-GFP at different MOI.
二。黑色素细胞分化相关蛋白-7（MDA-7）的克隆及功能研究：利用RT-PCR方法从5月龄人胚胎脾细胞扩增MDA-7的编码序列，经测序鉴定序列与文献报道一致后，与真核表达载体pcDNA3.0连接，构建pcDNA3-MDA-7表达载体，瞬时转染293、A549、Hela和HepG2细胞后抽提细胞总RNA，RT-PCR结果显示表达载体可介导MDA-7在不同细胞系中有效表达；转染48h后测定细胞增殖和活力，MDA-7可选择性抑制肿瘤细胞的增殖，对A549、Hela和HepG2细胞的抑制率分别为25％、20％和19％，但是对人胚肾来源的293细胞生长无明显影响。pcDNA3-MDA-7载体转染Hela细胞后，以G418筛选2周后计数单层细胞集落形成数，计数仅为转染pcDNA3.0空载体的细胞的30％左右。

CCSK is a rare type of renal neoplasm in childhood and its diagnosis relies mainly on histopathology and immunohistochemistry. It is important to be familiar with the morphological variants of CCSK to avoid confusion with other similar lesions, such as Wilm's tumor, congenital mesoblastic nephroma, malignant rhabdoid tumor of kidney, primitive neuroectodermal tumor.
CCSK是一种罕见的儿童期恶性肾肿瘤，诊断主要依靠组织病理学和免疫组化，熟悉其形态学变异有利于与其它类似病变如肾母细胞瘤、先天性中胚叶肾瘤、肾恶性横纹肌样瘤、原始神经外胚叶肿瘤等鉴别。

Results There were 8 angiomyolipomas, 2 leiomyomas, 2 multilocular cystic nephromas, 1 hemangioma and 1 mesoblastic nephroma. Only multilocular cystic nephroma and leiomyoma have special characteristics that can be determined from RCC.
典型的平滑肌瘤和多囊性肾瘤在CT上有可与肾癌鉴别的特征性表现：平滑肌瘤为规则圆形，边界清楚，密度均匀，CT值略高于肾实质，无钙化，弱强化；多囊性肾瘤为边界清楚的包块，可见边缘锐利含多个分隔的肿块，分隔之间为囊腔，囊内容物的CT值与水相似或稍高，而错构瘤、海绵状血管瘤、慢性肾脓肿、中胚层肾瘤在CT上无法与肾癌鉴别。

metanephrogenic blastema：生后肾原基
(2)生后肾原基:生后肾原基(metanephrogenic blastema)是中肾嵴尾端的中胚层组织受输尿管芽的诱导而产生的. 中肾嵴的细胞密集并呈帽状包围在尿管芽的末端,即成为生后肾原基. 生后肾原基的外周部分演变为肾的被膜,内侧部分形成多个细胞团,
-
mesomere：中节
肾脏是由中胚层的中节(mesomere)形成的生肾节(nephrotome)组成的. 在无羊膜动物,肾脏的发生要连续经过前肾(胚胎期)和背肾(成体)两个阶段;在羊膜动物则需经历3个阶段,即前肾、中肾和后肾阶段(图10-59).
-
metanephros：后肾
3.后肾 后肾(metanephros)发育为成体的永久肾. 人胚第5周初,当中肾仍在发育中,后肾即开始形成. 第11~12周,后肾开始产生尿液,其功能持续于整个胎儿期. 尿液排入羊膜腔,组成羊水的主要成分. 由于胚胎的代谢产物主要由胎盘排泄,
