The spinal cord, report Gaillard et al.1 in the current issue. Although the grafting of tissue to the brain has been explored as a strategy forrepairing the injured nervous system for over 100 years2, the current paper1 demonstrates a remarkable and complex set of long-distance,topographically appropriate axonal projections to a variety of targets distributed throughout the nervous system.

Gaillard等在当前的杂志中报告了放置入损伤的成年小鼠的运动皮质的胚胎皮层的移植物，令人震惊的是，它恢复了投射向远到脊髓的靶区的排列。

These mammary stem cells ensure the regeneration, galactopoiesis and degeneration of mammary gland in repeated pregnancy and birth.

因此，研究大鼠胚胎期和出生早期乳腺的各个发育阶段的形态学特点、各种细胞成分的组成和分布规律，以及乳腺干细胞在各个时期的特点将帮助我们更深入地了解乳腺的发生、发育以及乳腺干细胞的生物学特性，并有助于了解乳腺干细胞与乳腺发育、再生、癌变之间的关系。

This paper expounded the situation of animal somatic cell nuclear transfer and biological functions of centrosome and analyzed the inheritance mechanism of centrosome during gametogenesis and fertilization.

文章在分析哺乳动物体细胞克隆存在的问题和简介中心体结构功能的基础上，综述了中心体在配子和受精卵发育过程中的遗传机制，同时阐述了体细胞克隆胚胎中心体及其相关蛋白的研究现状。

The journal covers the research advances of the dynamics and mechanisms of sexual processes in all plants, including meiotic mechanisms, male and female gametogenesis and their related gene expression, fertilization mechanisms, gamete recognition, control of early embryogenesis and biotechnological applications in sexual reproduction etc.

该杂志涵盖了所有植物有性繁殖过程的动力学与机制的研究进展，包括减数分裂机制、雌雄配子形成与它们相关的基因表达、授精机制、偶合子识别、早期胚胎形成控制以及生物技术在有性繁殖中的应用等等。

Part I Cbx4 promotes SUMO modification of DNA methyltransferase 3a Dnmt3a is one of de novo DNA methyltransferases in mammals, which are responsible for the generation of somatic methylation patterns during embryogenesis and gametogenesis.

第一部分：Cbx4促进DNA甲基转移酶3a的SUMO化修饰 Dnmt3a是哺乳动物中的一个起始性甲基转移酶，负责在胚胎发育和配子发生过程中创建各类细胞的甲基化谱式。

To further understand mechanisms that control male gametogenesis and embryo development,we performed an genetic screen for mutations that caused distorted Mendelian segregation in Ac/Ds transposon system in Arabidopsis thaliana.

通过卡那霉素抗性(由突变体中标记基因编码)非孟德尔分离，从Ds插入的拟南芥突变体库中筛选到一个雄配子体发育突变体：ovp1和一个早期胚胎发生突变体eed1，我们对这两个突变体的表型和相关基因进行了研究。
