In the present review, we focus on some of the recent advances and some key developmental events revealed in the fertilization process, including the role of the egg apparatus in guiding pollen tube orientation, sperm cell movement to their targeting cells, interaction between gametes, egg cell activation, and onset of embryogenesis and endosperm development.

本文着重讨论受精作用的若干重要发育事件，包括受精前卵器细胞对花粉管向胚珠定向生长的近距离引导信号，精子的靶向运动，精、卵细胞相互作用和配子融合后卵细胞的激活与中央细胞发育的启动等。

Observing the mature embryo sac of the mutant: It was found thatthe embyo sac appeared in typical polygonum type and more than 90% of the embryo sac hadintegral inner structure. They had egg apparatus, two polar nucleus and three antipodal cells , and their position in the embryonic sac was normal .

幼穗分化、成熟胚囊观察发现，90％以上的胚囊具有完整的内部结构，有卵器、两个极核及多个反足细胞，且位置正常，胚囊呈现典型的蓼型结构；同时还观察到雌、雄器官的发育是同步的。

There are commonly eight nuclei in the embryo sac: the egg apparatus at the micropylar end, made up of an gee nucleus and two synergid nuclei; three antipodal cells at the oppsite chalazal end that probably aid embryo nourishment; and two polar nuclei in the center that fuse to form the primary endosperm nucleus.

通常胚囊中有8个核，卵器在珠孔端，由卵和两个助细胞组成；3个反足细胞在合点端，可能为胚胎提供营养；胚囊中央有2个极核，融合在一起形成最初的胚乳核。

Has 3 cells in the micropyle end: 2 help the cell and 1 egg cell.

在珠孔端具有3个细胞：2个助细胞和1个卵细胞。

结论原代心肌细胞可以作为组织工程学研究的种子细胞，它能够在聚酯类支架材料上种植、固定并生长，在体外成功构建工程化的心肌组织，为终末期缺血性心脏疾病的临床治疗带来希望。

Among of these, the research of TEHV has taken positive progress,but the research of EHT just started recently ,it is still facing a series of problem.At first,it is the selection of planting cells,how to take high degree of purity about cardiomyocytes should be overcome;Second,it is the selection of scaffolds,the biomechanical properties of scaffold been used still can,t meet the requirement.

首先是种子细胞的选择，如何获取纯度较高的心肌细胞，还需从各种种子细胞中进行筛选；其次是支架材料的选择，目前应用的材料在生物力学特性上还不能满足临床使用的要求，还无法承受左心室巨大压力的冲击，因此还有待进一步的研究和改进。
