The vascular changes interfere with diffusion of nutrients from plasma into adjacent perivascular tissue and cells. 这些血管变化干扰了营养物质从血浆中向血管周围邻接的组织和细胞扩散。
The pathological characteristics are as follows: 1. perivascular cuffs of inflammatory cells infiltrates, especially around the small venules in cerebral parenchyma, spinal cord and subarachnoid cavity; 发病动物病理改变如下:1.脑、脊髓实质及蛛网膜下腔小静脉周围炎性细胞浸润,呈袖套状改变;
The result showed that in embryonic bone, BMP was mainly distributed in the periosteum, Perichondrium, chondroblasts. osteoblasts, perivascular messenchymal cells, osteogenic cells. 结果显示:BMP在胎儿软骨膜、骨膜、成软骨细胞、成骨细胞和血管周围等部位有大量分布;
In transverse section, they consisted of 6~ 11 cuboidal endothelial cells. The postcapillary venules were surrounded by perivascular cells. 在横断面上,它们由6~11个立方状内皮细胞围成,1~3层血管周围细胞包绕整个外周。
Perivascular infiltrate of memory lymphocytes and mature dendritic cells in MG thymomas MG合并胸腺瘤患者的记忆淋巴细胞和成熟树突状细胞的血管周围浸润
The release of small cytoplasm fragment: The long processes of the cells can protrude into the perivascular space and then the end of the processes departs from the cells, finally the cytoplasm fragments that contain secretary granules enter the sinusoid from the capillary pore. 以胞质小块释放入血窦:有突起的细胞将突起伸入血管间隙,末端与细胞脱离形成含分泌颗粒的胞质小块,经内皮窗孔进入血窦;
In the retinoic acid induced cleft palate group, strongly expression of dense type and distribution on the palatal median crest and perivascular mesenchymal cells, the expression of palatal anterior part more than the posterior part. 在维甲酸诱导腭裂组中,致密型强表达分布于腭突正中嵴处以及血管周围的间充质细胞中,前部腭突多于后部。
