ObjectiveThis experiment attempted to determine the effects of the teratogen cyclopamine on the Shh signaling pathway in axolotl embryos. Groups of axolotl embryos that had undergone gastrulation were ...

PURPOSE: The objective of this experiment is to study the effect of lithium chloride treatment on early blastula xenopus embryos.INTRODUCTION: When the developing embryos of many organisms such as the ...

The development of chick embryos has been studied since Aristotle. It is one of the most intensely studied organisms. One reason for this is that there are great similarities between avian and mammali ...

This experiment allows you to observe the development of a chick embryo outside its shell. Cultured chicks are also more accessible for manipulation. Compare the extent of bone mineralization of contr ...

In order to repeat a published experiment or have someone else repeat yours it is important to use the same materials. For developmental studies that means knowing the precise point in development tha ...

ABSTRACTFibroblast growth factor (FGF) signaling plays a signifigant role in embryonic development. Particularyl FGFs are implicated in mediating epithelial-mesenchymal interactions by means of regula ...

ObjectiveThis experiment explores the ability of the chick chorioallantoic membrane (CAM) to support an excised limb bud from a donor embryo. The chick system will allow observation of general cartila ...

Abstract Choriallantoic membrane (CAM) limb grafting functions as a method to isolate the inductive events of limb formation. Experimenters have the ability to isolate and culture tissues outs ...

The chicken is a classic organism used to illustrate the principles of basic embryology. One of the developmental systems which has been examined in great detail is the circulatory system. In the deve ...

Objective:The purpose of this experiment was to explore the effects of the growth factors bFGF and VEGF on blood vessel formation within the chorioallantoic membrane (CAM) of chick embryos. Background ...

ObjectiveThe purpose of this experiment is to observe the effect of caffeine on the heart rate of three day old chick embryos by directly treating them with five different concentrations of caff ...

Green fluorescent protein (GFP) is responsible for the bioluminescence of the Pacific Northwest jellyfish Aequorea victoria. In A.victoria the 27-kDa protein absorbs blue light from a photoprotein tha ...

More than 22 million American women smoke and approximately 25% of these women continue to smoke during pregnancy (Lambers and Clark 1996). Cigarette smoke has long been associated with increased heal ...

动物的受精作用所涉及的反应 在哺乳动物、鸟类、爬行动物，受精作用发生在雌性动物的生殖系统内，而在两栖类、鱼类、无脊椎动物，受精作用发生在体外。不管是何种情况，受精作用都具基本相同的过程：精卵间的接触、精子对卵被的穿透、精子与卵子质膜的融合、卵的激活。涉及的反应包括：顶体反应、皮层反应、原核融合等。1．顶体反应 是受精作用的反应之一，受钙离子的调节。反应过程较长，包括顶体受体的激活、 ...

动物来源：1909年C.C.Little用小鼠作毛色基因研究时培育而来。最初命名为drb，后来改名为dba，继而改为DBA。 1929～30年从这小鼠中分离出DBA/1和DBA/2，1948年到美国Jackson Lab.，成为DBA/2J亚系。七十年代到日本实验动物中央研究所，1987年自日本日本实验动物中央研究所引入到中科院上海实验动物中心。 动物外部特征：淡棕色 遗传基本组成：a/ab/bd ...
