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.

骨髓基质干细胞的软骨分化潜能使其可能成为可注射组织工程化软骨研究的种子细胞，为探讨体外培养的骨髓基质干细胞在平面诱导条件下软骨分化的可行性，我们进行下列实验：获取并体外平面培养成体兔骨髓基质干细胞，应用TGF-β〓、Vit-C和地塞米松对其软骨分化诱导，诱导后的骨髓基质干细胞行细胞爬片组织学和Ⅱ型胶原免疫组化，结果证实，诱导后骨髓基质干细胞可分泌Ⅱ型胶原，组织学染色可见类似于软骨细胞，由此证明体外培养的骨髓基质干细胞在平面诱导条件下可以软骨分化，其软骨诱导因子为TGF-β〓、Vit-C和地塞米松。

The results showed that:(1) Many proliferating cells were distributed unevenly in the ventricular zone of telencephalon, and the [3H] labeled cells were found to be populated in the lateral ventricular zone of neostriatum at brain level L12~L14,forming proliferation "hot spots";(2) Having underwent mitosis twice, the proliferative cells in the VZ began to migrate laterally 6 days after intramuscular injection of [3H] thymidine, and these migrating precursor cells terminated at their targets and differentiated into new neurons on the 30th day.

结果发现：①端脑室带区中存在不均匀分布的[3H]标记细胞，大量标记细胞分布在端脑尾侧新纹状体水平(L1～L14)的VZ，形成标记细胞的&热点&区；②标记细胞经两次有丝分裂后，大约在肌肉注射[3H]的第6天后开始从VZ向外迁移，在30天左右到达目的脑区并分化成为成熟神经元。

The therapy groups displayed significant improvements in neuromotor functions and survivals of neuron and oligodendrocyte compared with control groups. These results demonstrated the neuroprotect roles of GGF2, and cationic liposome-mediated GGF2 transgene therapy has potential possibility.

结果：1、大鼠LFP致伤后3—7天，GGF2 mRNA在海马CAl区、CA2区、CA3区、DG及皮层表达明显增加。2、阳离子脂质体介导GGF2转基因治疗可促进大鼠伤后行为学的恢复，可促进损伤区神经元及少突胶质细胞的存活。3、原核表达方法得到GGF2重组蛋白。

The coarse needle-like or nubby Al9FeNi phase existed in the cast microstructure of high content Fe and Ni alloy 2618(2#). After hot extrusion, it was broken into coarse multi-angle Al9FeNi particles. The contents of Fe and Ni have no effect on aging characteristic and the hardness of the alloy after aging.

含锆的高铁、镍2618合金经熔体高温过热处理后(4#)，在合金铸态组织中获得均匀细小的针片状Al_9FeNi相，热挤压后获得均匀细小的颗粒Al_9FeNi相；弥散Al_3Zr粒子的存在可使2618合金得到细小的再结晶晶粒组织，该合金既可获得较高的高温强度，还可获得较高的延伸率。

The results showed that the lower agglutination titers were observed at day 7 and up to higher levels over 〓 or 〓 at day 21 induced by the vaccine of recombinant pilin and the recombinant fused protein respectively. Above results suggested that the good immunogenicity of the two recombinant vaccines could match with both the D.
