SCs divided and proliferated in three-dimensional fashion, demonstrating long olivary, triangular or long fusiform shape with obvious prominence. Furthermore, The SCs connected end-to-end with each other or aligned in clusters and the protein granules secreted on cellular surface were also showed.

雪旺细胞分裂增殖呈三维生长，细胞形态多为长梭形，纺锤形或长三角形，突起显著，细胞呈端对端的相互连接或排列成束状或栅栏状，细胞表面蛋白颗粒分泌良好。

Methods BMSCs isolated from rabbit iliac bone marrow were culture-expanded in vitro. The injectable tissue-engineered bone constructed from autologous PRP, FG, and BMSCs was cultured in vitro, and its biological characteristics were observed including the time of gel formation, histological features, seed cell survival and microscopic structures. Results The constructed injectable tissue-engineered bone began gel formation within 20 to 30 s, and after a week-long culture, the gelatine began to degrade, and numerous well viable fusiform cells could be seen to adhere to the bottom of the Petil dish, Scanning electron microscopy identified globular and olivary cells embedded in the fibrin glue, and numerous small particles could be seen around of the cells.

从兔髂骨处抽取骨髓体外培养BMSCs并诱导向成骨细胞分化，抽取兔自体动脉血提取PRP，以FG、BMSCs、PRP共同构建可注射型组织下程骨并体外培养观察其生物学特性如凝胶形成时间，组织学特点、细胞存活情况及其超微结构特征等结果构建的可注射型组织工程骨可在短时间内形成凝胶，体外培养1周时其中细胞生长良好，电镜下见纤维蛋白网格结构致密，种子细胞及血小板颗粒分布广泛。

Results: nk 4r immunoreactivity was found extensively localized in neuronal somata and neurite of cerebral cortex, and mainy in layer ⅲ,ⅴ. double labeling experiments confirmed that 100% nk 4r immunoreactive neurons co expressed neun, but not gfap.

结果：nk 4r免疫阳性产物在皮层的锥体细胞层分布最多，在皮层内、外颗粒层、多形层也广泛分布，其阳性产物表达于神经元胞体和突起上，免疫荧光双标结果观察到nk 4r与神经元胞核特异性标记物neun共存（100%，146/146，双标细胞数目/nk 4r阳性细胞数目），且不与星形胶质细胞标记物gfap共存。

Results: The number of BrdU-positive cells in the subventricular zone and in the subgranular zone of dentate gyrus,and the numbers of ChAT-positive cells in medial septumand diagonal band of the basal forebrain were significantly decreased in lead exposed group P
