It was a new mousegene in GenBank and named as SRG-L(spermatogenesis related gene expressed in the latestages of spermatogenic cells). The sequence of this cDNA has been deposited in GenBankwith the Accession No. AY352586. 2. Analyses of expression characteristics of SRG-L during mouse spermatogenesis.The results of RT-PCR and Northern Blotting indicated that no expression signal of thisgene could be observed in primitive type A spermatogonia and type B spermatogonia. Asignal first appeared in diplotene/pachytene spermatocytes, and was significantlyintensified in round spermatids and elongating spermatids, findly went down to beundetectable in mature spermatozoa.

RT-PCR和Northern Blotting分析表明：该基因在早期A型和B型精原细胞中不表达，从双线期初级精母细胞阶段开始表达并逐渐上调，在粗线期初级精母细胞、圆形精子细胞及长形精子细胞中均检测到高水平的mRNA，但在成熟精子中消失，具有明显的阶段特异性表达特征，并且组织特异性表达分析显示该基因在睾丸组织中的呈高表达。

This process aims at recapitulating the normal embryologic development of the organ of interest. The main difference between in vivo technology and in vitro technology is: in vitro technology emphasis on in vitro cell culture. It has special value for the specific tissue such as articular cartilage.

体内组织工程技术与体外组织工程技术的目标相同，都是实现组织完全再生；区别在于其达到再生的方法：体外组织工程技术强调细胞的体外培养，并使这些细胞产生功能，这对有些组织有特殊价值，如软骨。

The leaf epidermis structures of 6 species of Rhododendron had been observed under LM and SEM. The results show that all share together common features as follows: the leaf blades are typical back-abdomen bifacial types, the upper epidermis are formed by two or three layer bigger cells which inside layer cell is bigger than outside one, and the upper epidermis are covered with thicker cuticle.

Three-dimensional Matrigel constructs contained aleolar forming units comprised of cells displaying AE2 cellular ultrastructure while expressing the SpC gene and gene product. The addition of tissue-specific growth factors induced formation of branching, sacculated epithelial structures reminiscent of the distal lung architecture.

通过对细胞亚微结构的观察和对SpC基因及其表达产物的分析，研究者发现培养体系中肺组织形成单位中具有能向肺泡II型上皮细胞分化的细胞；而通过添加组织特异性的生长因子，他们还发现这一做法会促进培养组织形成具有分支和囊状上皮结构的类似终末肺泡组织的形态结构。

A 46-year-old man presented with a gradually growing nodule on the left dorsal foot, which had been present for over 10 years. In the beginning, the lesion was treated as a keloid. Because of poor response to treatment, biopsy was arranged. Sections showed a dermal tumor composed of numerous foamy cells, hyalinized wiry collagen, spindle cells and entrapped collagen. The foamy cells were positive for KP1(CD68) and negative for S-100 protein and HMB-45. The histological and immunohistochemical results were consistent with the diagnosis of lipidized fibrous histiocytoma.

CGRP content in myocardium gradually enhanced from normal group to controls group, and model group's was the highest. We found immunopositive neurons and nerve fibers of nNOS and CGRP by immunochemistry in normal myocardium. They were mainly round-shaped and oval-shaped, also tadpole-shaped、 shuttle-shaped、triangle-shaped、ring-shaped and irregular-shaped. Nv of neurons and nerve fibers in atria were more than in ventricle in some degree; Those in right part of heart were more than in left. Morphology of CGRP neurons changed in model group, the number of ring-shaped neurons increasing, while the round-shaped and oval-shaped decreasing, and Nv and Sv of model group were markedly less than normal. Expression of nNOS mRNA was overly higher than normal group, but CGRP was opposite.
