The developing tooth is a particularly good model for studies on the regulation of organogenesis, including morphogenesis as well as cell differentiation.

脊椎动物器官在发育过程中的形态发生和细胞分化都是由上皮细胞和外胚间充质细胞的相互作用所调控的。

Firstly,the presence and location of AAT in amphioxus was studied by Westernblotting and immunohistochemical methods.The results first revealed that AATpresent in amphioxus,a cephalochordate.Also it was demonstrated that AATdistributed in cellular plasma in hepatic diverticulum,the pouch that protrudesforward as an outpocketing of the digestive tube and extends along the right side ofthe posterior part of the pharynx,which has long been considered to be the precursorof vertebrate liver.In vertebrate,AAT is primary synthesized in liver.

我们首先利用免疫组化和Western blotting方法，研究了AAT在文昌鱼的组织表达和定位，首次在头索动物文昌鱼中证明了AAT的存在，结果显示，AAT定位于文昌鱼肝盲囊的细胞浆内，从AAT在文昌鱼中的合成部位来看，在功能上文昌鱼的肝盲囊等同于脊椎动物肝脏，肝盲囊是在发育分化过程中消化道组织向右前方突出沿着咽后部向前扩展和延伸形成的一个囊袋状结构。

The usually paired female or hermaphroditic reproductive organ that produces ova and, in vertebrates, estrogen and progesterone.

卵巢通常成对的雌性或雌雄同体动物的生殖器官，产生卵细胞，脊椎动物的此类器官产生雌性激素和孕激素

In the endangered vertebrates, 37% species of them are threatened by overdevelopment , and many wild animals are hunted and killed for the food material or the daily necessities and so on.

在濒临灭绝的脊椎动物中，有37％的物种是受到过度开发的威胁，许多野生动物被猎杀而做为食材或生活用品等。

Louis Mazzatenta The Institute of Vertebrate Paleontology and Paleoanthropology, part of the Academia Sinica in Beijing, houses the fossilized teeth of the dinosaur Beipiaosaurus.

古人类学和古生物学脊椎动物的学会，部分的中国的学术界在北京，库房存放恐龙化石的牙齿标本。

It has been caused much attention by many geologists at home and abroad. Based on the rich dinosaur resources in Henan Province, the author has obtained some important results through the scientific study and protection research of dinosaurs and,these results can help to discover more and more complete dinosaurs and other vertebrate fossils, to promote and raises the research level on the systematic paleontology and dinosaurs in Henan Province, and thus provides important scientific data on stratigraphy, paleogeography and paleoenvironment of Mesozoic basins, which can accelerate to build protection system at all levels and geological parks, all these can bring about a great advance in environment protection, tourism economy, agriculture, industrial production and social civilization.

以河南丰富的恐龙化石资源为依托，通过对恐龙化石的调查、发掘，科学特征和保护研究，不仅可获得一批重要的科研成果，促使发现更多更完整的恐龙化石和其它脊椎动物化石，促进和提升河南省恐龙研究水平，为中新生代盆地地层学和古地理、古环境研究提供重要的科学素材，而且可促进地质遗迹保护和地质公园建设，带动生态环境保护、旅游经济等方面的发展，达到促进地区经济效益增长和社会进步之目的。

Pantothenic acid(vitamin B5) The precursor of coenzyme A,pantothenic acid is essential for several fundamental reactions in metabolism.

泛酸在新陈代谢的一些基本反应中是必不可少的，它是水溶性的维生素B族的成员之一，由植物和细菌合成，而脊椎动物不能合成泛酸。

Parthenogenesis occurs naturally in some species, including invertebrates and lower plants. It happens more rarely in some vertebrates.

某些生物天生具有单性生殖的能力，包括无脊椎动物和低等植物，但单性生殖在脊椎动物中较为罕见。
