In addition, using RT-PCR to detect expression of centrin homogene during Urechis unicinctus spermatid deferentiation and early embryonic development. The result revealed that (1) expression of HsCEN1 homogene is present during spermatid defferentiation including spermtid and sperm, but not in adult tissues including body wall tissue,intestinal mucous memberane cells and cell in coelom succus;(2) expression of HsCEN1 homogene is not present in unfertilized oocytes but present in that of released polar bodies after fertilization and parthenogenesis oocytes treated with A23187;(3) expression of HsCEN1 homogene is present during early embryonic development including two-cell stage,multicell stage,gastrula to trochophora.

我们还用RT-PCR方法检测了Centrin同源基因在单环刺螠精子分化过程和早期胚胎发育过程的表达，结果显示：在单环刺螠精子发生过程中的精细胞、精子团、精子中都有表达，而在成体的体壁组织、消化道组织、体腔球中则没有表达；在未受精卵中没有表达，而在受精后释放极体的受精卵和经A23187孤雌激活的卵中则有表达；在单环刺螠的早期发育过程——二细胞胚胎、多细胞胚胎、原肠胚、早期担轮幼虫——中都有表达。

Bone marrow-derived mesenchymal stem cells are capable of chondrogenesis, making them a possible source of cells for injectable cartilage tissue engineering. There exist different ideas on the ability of mesenchymal stem cells's chondrogenesis in monolayer culture. Because of this, the effect of adult rabbit's bone marrow-derived mesenchymal stem cells chondrogenesis in monolayer culture was studied. The mesenchymal stem cells was isolated from adult rabbit's bone marrow and monolayer cultured. TGF-β1, Vit-C and Dexamethasone were used. Immunohistochemistry analyses and histological staining of H-E, Methylaniline blue and Alcian blue were performed to identify the expression of collagen type Ⅱ and cartilage associated matrix. The results showed that the induced cells expressed and produced collagen type Ⅱ and cartilage associated matrix. This suggests that the differentiation of adult rabbit's marrow-derived mesenchymal stem cells into chondrocyte in monolayer culture is feasible and may be induced by TGF-β1, Vit-C and Dexamethasone.

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。

Results: Embryoid bodies grew well in Collagen Gel, the differentiated cells grew into the gel gradually; electronmicroscope showed that some induced cells were rich in Golgi's bodies and endoplasmic reticulums, a few secretory granules were also visible, which was similar to human adult thyrocyte.

The quantity of CD3+ cells in the EdNSC, AdNSC of cloning goattransplantation group and control group had no statistics difference(P＞0.05) at acute and chronic period.Overall, in our study, We got the conclusions as follow: 1,The EdNSC, AdNSCof cloning goat and the AdNSC of the non-cloning goat were successful obtained;EdNSC growed faster than AdNSC in the same cell culture method. 2,The braincontusion and laceration model of cloning goats were successful established by freefalling of 50 gram of steel ball accelerate strike on the goat brain from 100cm height.3, EdNSC and AdNSC transplantation both had obvious therapeutic effect on braincontusion and laceration of cloning goats; The therapeutic effect of EdNSCtransplantation was better. 4, Allograft of stem cells has acute and chronicimmunological rejection and autografting of stem cells has no acute and chronicimmunological rejection.
