纤维所成的

The results are as follows: 1The collagenous fibers are arranged in a crass-crossed network of three dimentions. The network in an area of less than 500 μm is like a small board called a microboard. All microboards anastomose each other, forming a microboard network; 2The so-callcd collagenous fibers or lamellae about 4—9 μm thick under the LM are really th...

We identified that in vitro ASM promotes fibrocyte chemotaxis and chemokinesis (distance of migration after 4.5 hours, 31 mum [2.9 mum] vs 17 mum [2.4 mum], P =.0001), which was in part mediated by platelet-derived growth factor (mean inhibition by neutralizing antibody, 16% [95% CI, 2% to 32%], P =.03) but not by activation of chemokine receptors.

Rat dermal fibrobalasts and human neofetus dermal fibroblasts were cultured in vitro to evaluate the biocompatibility of the chitosan films.

为考察壳聚糖对皮肤成纤维细胞的相容性，采用流延法制备了纯壳聚糖膜和含甘油的壳聚糖膜，并在所制备的壳聚糖膜上进行了大鼠皮肤成纤维细胞和人胎儿皮肤成纤维细胞的体外培养。

Primary culture of goat mammary gland cells could be derived by outgrowth of migrating cells from fragment of tissue. Fibroblast and epithelial cells could be pured according to their different sensibility to trypsin. Complex cultures treated by 0.25% trypsin in Hanks' for 5~7min at 37℃, the dispersed cells were mainly fibroblasts,then the rest treated by 0.15% trypsin-0.02% EDTA in Hanks'for 5~8min at 37℃, the majority cells harvested were mammary epithelial cells.

用组织块培养法可获得良好的山羊乳腺细胞原代培养物；培养的山羊乳腺成纤维细胞比上皮细胞对胰蛋白酶更敏感，据此可在传代过程中将二者分离纯化，获得纯细胞系；混合培养物先用0.25%胰蛋白酶在37℃消化5~7min 所收集的细胞主要为成纤维细胞；再加0.15%胰蛋白酶-0.02鞹A 消化液在37℃继续消化5~6min 所回收的细胞绝大多数为上皮细胞，经过2~3 代，即可得到纯化的乳腺上皮细胞系。

On the termination date, the cultured explants were all examined by Western blot, HE and transmission electron microscope. Our results showed that after 12-days in culture, the cultivation treated with AS-ODN reduced the synthesis of AMBN and had a deformed dental cusp with thinner enamel matrix. Ultrastructure analyses showed that there was hardly any cisternae of the rough endoplasmic reticulum in the ameloblasts at the tip of the cusp of AS-ODN treatedexplants. However, on average the enamel matrix was thinner compared with that in the control group. Furthermore, the collagen fibers in extracellular matrix were found disorganized. These findings seemed to provide a direct experimental evidence that tended to indicate that the arrested AMBN translation in cultured tooth germs might result in the delay of the tooth development.

经用Western蛋白印迹检测表明，所设计的反义核酸对AMBN InRNA具有良好的封闭效果并成功阻断了牙胚对AMBN的表达；在缺乏AMBN情况下，与对照组相比，实验组牙胚在体外可以继续生长发育至钟状晚期，出现成釉细胞和成牙本质细胞的分化，成釉细胞可以分化成为分泌期型成釉细胞，胞浆中缺少合成蛋白质所必需的粗面内质网和高尔基氏体，缺乏溶酶体，表明对蛋白合成和脚的能力降低；实验组牙胚有牙尖形成和基质分泌，但牙尖形态异常，基质形成减少，牙尖周围基质最厚处为O.6卜m，明显薄于对照组的5.spin，基质中胶原纤维粗细不等，排列稀疏， 3 第四军医大学硕士学位论文未见钙化现象，充分证明了AMBN在牙胚发育中参与釉质基质形成和矿化过程，影响胶原纤维和牙本质基质的合成，促进成釉细胞对蛋白质的合成和釉质基质蛋白降解。

To understand the infectivity by porcine endogenous retrovirus with porcine skin fibroblast cell in vitro and in vivo, porcine skin fibroblast cell established by our laboratory were co-cultured with neo/HEK293 cell for the infection of RERV in vitro, and were subcutaneously transplantated to SCID (severe combined immuno-deficiency) mice for the infection of PERV in vivo, laying the foundation for valuation of biologic safety of xenotrans-plantation. The event of neo/HEK293 cells infected by PERV occurred during co-culture of porcine skin fibroblast cells with neo/HEK293 cells, expanding the rang of the infection of porcine endogenous retrovirus. Afterpig cells transplantated subcutaneously in SCID mice, the microchimerism (78.57%) of pig cells occurred widel, and there was phenomena of integration of PERV provirus (85.71%) in several organs or tissues remote from the injected sites, indicating infection of PERV in SCID mice in vivo. yet, there is no evidence of active viral replication in analysis of PERV env RNA of these tissues or organs.
