An experiment was performed to compare effect of different cell media on embryonic germ cells derived from primordial germ ridge of Kunming albinotic strain mouse.

以昆明白品系小鼠胎儿生殖嵴为材料，以不同的培养液分离培养胚胎生殖细胞，发现小鼠胎儿肝细胞条件培养液的效果好于未添加白血病抑制因子的基础培养液，而差于添加了1 000 IU/mL LIF的基础培养液。

Allantois and surrounding tissues of 8.5 day post coitum embryos, the hindhut and surrounding tissues of 9.5 dpc and 10.5 dpc embryos, the gonadal ridges and surrounding tissues of 11.5 dpc and 12.5 dpc embryos were collected and digested with 0.25%pancreatin-0.02%EDTA, then the cells were cultured in the plastic petridishes which are pretreated with 0.1% gelatine.

实验方法：取胚龄8.5 d胎鼠尾端尿囊及周围组织，取胚龄9.5~10.5 d胎鼠后肠及周围组织，取胚龄11.5 d，12.5 d胎鼠生殖嵴及周围组织，分别经0.25%胰酶-0.02%EDTA消化并接种于0.1%明胶包被的培养皿中。

The typical pathological characteristics of SPTs may result from gradual degenerative changes induced anoxemia in some SPT's areas. The heterogeneity of SPTs on different antibody markers showed that the SPTs may be originated from pancreatic embryonic stem cells, and result from immature differentiation of the pluripotential stem cells during pancreatic genesis.

SPT典型病理特征是由于肿瘤组织不同区域相对缺血、缺氧所造成的退行性变的结果，SPT表达多种组织来源的抗原，反映其可能来源于胰腺干细胞及与其发育密切相关的胚胎神经嵴的神经前体细胞，且在发育过程中发生分化不成熟的结果。

During the early stage of embryogenesis, FoxD1 was mainly expressed in the somites, kidney progenitor cells, brain progenitor cells and intestine.

在胚胎发育早期，FoxD3在未迁移神经嵴前体细胞、体节、耳后的基板、头部和躯干的神经嵴细胞、松果体中表达。

Heart malformation, such as PTA, DORV, VSD and aortic arch malformation, were detected when neural crest were taken out before they migrated into 3, 4, 6 pharyngeal gland. Interestingly, the types of malformation were related with the length of neural crest destroyed; PTA was detected if the length exceeds two somites, while DORV would be detected if the length less than two somites. These results indicate that CNCCs are very important to the conotruncal development.

研究发现，如果在迁移之前切除散发到第3、4、6咽弓的神经嵴细胞，就会出现永存动脉干、主动脉骑跨、右室双出口、主动脉弓畸型和室间隔缺损等心血管畸形，且切除的长度与畸形的种类相关，如切除长度大于两个体节可产生永存动脉干，切除长度小于两个体节则产生右室双流出道，由此可见，心脏神经嵴细胞对于心脏圆锥部的发育意义重大。

This same anatomic configuration also allows some movement between the crest and the septum, and it is this instability that explains the frequent posttraumatic findings of a displaced quadrilateral septal cartilage from the groove of the crest.

同时这样的解剖特点，也使得鼻中隔和腭嵴之间有一定的活动度，正是这种结构的不稳定性可以解释为什么在创伤后经常容易发现四边形的鼻中隔从腭嵴凹槽上脱位。

同时这样的解剖特点，也使得鼻中隔和腭嵴之间有一定的活动度，正是这种不稳定的结构可以解释为什么在创伤后经常轻易发现四边形的鼻中隔从腭嵴凹槽上脱位。

Zygomaticoalveolar crest is the major site to sustain stress , which indicates that the fixation of zygomaticoalveolar crest should be strengthened and bony zygomatic process support should be rebuilt .

颧牙槽嵴是腓骨瓣上颌骨重建后咀嚼压力的主要受力部位，腓骨瓣上颌骨重建时要加强颧牙槽嵴的固定，重建骨性颧突支柱。

AIM: To construct a three-dimensional finite element model of human mandibular alveolar atrophy, which uses to analysis the biomechanical characters of atrophic alveolar ridge.

目的：利用螺旋CT建立牙槽嵴萎缩的下颌骨三维有限元模型，用于萎缩牙槽嵴的生物力学分析。

Lugalbanda was a god and shepherd king of Uruk where he was worshipped for over a thousand years.

Lugalbanda 是神和被崇拜了一千年多 Uruk古埃及喜克索王朝国王。

I am coming just now,' and went on perfuming himself with Hunut, then he came and sat.

我来只是现在，'歼灭战perfuming自己与胡努特，那麼，他来到和SAT 。
