The whole embryonic developmental course results from the ordinal expression of a large number of genes according time and space. Many developmental mechanisms have been determined in the embryonic stage. Therefore, study on the regulative mechanism of embryonic development is important for elucidate principles of biologic growth, development and evolution.
整个发育过程都是大量的基因按照一定的时间、空间和次序表达的结果，其中许多调控机制在胚胎发育阶段就已经决定，因此，研究胚胎发育调控机制对于阐明生物的生长、发育和起源进化具有重要意义。

Using GSA-〓 lectin histochemistry, the first appearance of microglia occurred at E13, usually stained as scattered amoeboid cells. From then on, the number of microglia increased steadily, reached a peak at postnatal day 7 (P7), and then reduced gradually to adult level. Generally the morphological form of microglia undergoes transformation from early rounded or ameboid to adult resting ramified as they differentiate during development.
使用凝集素GSA-〓亲和组织化学染色，本实验最早观察到小胶质细胞在胚胎13天（E13），为散在分布的圆形或阿米巴样细胞，随后细胞数量逐渐增多；总体而言小胶质细胞的形态遵循着由圆形或阿米巴样逐渐转向纤细分枝状的演变规律，不同阶段细胞形态各有其特点，在不同区域也存在差异；小胶质细胞的数量在生后第七天（P7）达到高峰，其后开始逐步降低直至成年。

Conclu sion:(1)Surface densities of PCNApositive cells reached their peaks on 14th day after birth,but the number of apoptotic cells reached its peaks on 21st day p ostnatal,so the apoptotic peak was late the proliferating peak for a week,and related to the particular period in cycle of seminiferous epithelium;(2)The spe rmatogium were found move from center to the periphery of the seminiferous tubule and arrange disorder to order;(3)The spermatogonium remained replicating activ ity of DNA during the developing stage.
生精细胞凋亡的高峰要滞后其增殖峰1周左右，而且与其所处生精周期的特定阶段有关；（2）精原细胞在胚胎发育过程中向曲细精管周边迁移，其排列由无序到有序；（3）在生后各发育阶段中，精原细胞始终保持DNA复制的能力。

Thus gp130 is the common signal transduction molecule. Gp130 molecule expresses universally on many tissues including immune system, hemapoietic system, and nerve system. Gp130 has an essential role in the function and regulation of the above systems, especially in the development of hemapoietic system. The signal transduced by gp130 is necessary during the differentiation and proliferation of hemapoietic cells. It is evidenced that the embryo of gp130 gene-knockout mouse was dead due to a serious impediment of the development of hemapoietic system.
Gp130在人体组织细胞上广泛性表达，介导和调节机体的免疫、造血以及神经系统的生理功能，尤其是在造血系统的发育过程中，具有极其重要的作用，动物实验表明，敲除小鼠的gp130分子基因可以使其在胚胎的早期阶段产生严重的造血系统障碍，最终导致流产，由此表明在造血细胞的分化、发育和生物学行为中，gp130介导的信号是必不可少的。
