We also have captured the primary spermatocytes and round spermatids from rat testis sections by the application of the Laser Capture Microdissection technique.

RSB-66基因就是从初级精母细胞消减圆形精子细胞得到的SSH文库中得来的，这个蛋白质可能在精子发生过程中起重要作用。

With the development of embryo, Myf5 expression decreased gradually in somites in the anterior region, but remained strong in the newly formed somites; After 30 somites formed, MyoD expression decreased in the somites except the caudal somites. At the hatching stage, MyoD and Myf5 were expressed in head muscle cells and fin muscle cells. In the growing fish, Myf5 was expressed in the skeletal muscle and intestine, and in adult flounder, Myf5 was only expressed in muscle. In the growing fish and adult fish, MyoD was only expressed in muscle.

在胚胎发育早期，Myf5在近轴中胚层中表达，体节发生过程中，Myf5在体节中表达，MyoD基因最早在分节板的体节前细胞中表达，随后在近轴细胞、体节中表达；随着胚胎的发育，Myf5在成熟体节中表达量降低，在新生体节中表达较强；MyoD自30个体节时期后只在新生的尾部体节中表达，在成熟的体节中表达量降低；在孵化期，MyoD和Myf5在头部及鳍的肌肉、尾部的体节中表达；生长期的牙鲆中，Myf5在骨骼肌和肠中表达，成体牙鲆中，Myf5只在肌肉中表达；生长期的牙鲆及成体牙鲆中，MyoD只在肌肉组织中表达。

At 24 h, Ang1 was expressed mainly in the lens, optic cup, mesencephalon, ventral part of hindbrain, and myotomes in the somites, while zfTie2 was mainly expressed in intersomitic vessels including dorsal aorta and axial veins, and sprouting vessels from the dorsal aorta in the trunk.

采用多聚酶链式反应，扩增了长约280bp的斑马鱼血管发生素1 cDNA部分序列，作为探针，以原位杂交法测定了血管内皮细胞生长因子和血管发生素1及其相应受体flk1和Tie2的表达。

Results:Compared with the untreated fibroblast from hypertrophic scar, the rough endoplasmic reticulums were decreased, the ribosome were appeared degranulation and depolymerization and lysosomes were lncreased respectively.

结果：Mat可使增生性瘢痕成纤维细胞的超微结构发生变化；细胞内粗面质网减少，核糖体有部分脱粒、解聚现象，溶解体酶，核染色质浓缩集聚至核膜周边，出现凋亡早期的改变。

Lipid scrambling in resealed ghosts occurs in the absence of cell shrinkage and microvesicle formation, processes that are generally attributed to Ca(2+)-induced lipid scrambling in intact erythrocytes.

重封血影细胞中的脂质紊乱在细胞皱缩缺失和微泡形成时发生，此过程在完整的红细胞中通常归因于Ca(2+)诱导的脂质紊乱。

The fusing of bone marrow stromal cells and neuronal cells results in the change of cell phenotypes.

骨髓间质细胞与神经元的融合导致细胞表型发生变化。

It is suggested that PAMs may be in thelower activity at the early stage of postinoculation,and it may be in the disorder ofglycometabolism,fat metabolism and constructive metabolism after PRRSV infection.

表明PRRSV感染早期肺泡巨噬细胞处于低功能状态，PRRSV感染可造成肺泡巨噬细胞糖类代谢和能量代谢发生障碍，合成代谢及物质运输等功能低下。

Within the cell, further division of labor occurs between the organelles.

在细胞内，进一步的分化发生在细胞器之间。

The callus started to produce near the surface of the wound from the remaining immature xylem cells including xylem parenchyma cells and xylem ray parenchyma cells...

愈伤组织由靠近伤口表面未成熟的本薄壁组织细胞和木射线细胞分裂产生，维管形成层在愈伤组织内层发生，且是一个渐进的过程。

Moreover, re-expression of FHIT in FHIT-deficient cancer cell lines induced apoptosis, cell cycle arrest, and suppression of tumorigenity in nude mice reviewed in ref.

FHIT蛋白在FHIT缺失肿瘤细胞系中的重新表达可诱发裸鼠发生细胞凋亡，细胞周期停滞，并抑制了肿瘤生成。
