产品概述
人角膜成纤维细胞
Cat NO.: CP-H131
-
产品名称:人角膜成纤维细胞
-
组织来源:眼角膜组织
-
产品规格:5×10⁵Cells/T25培养瓶
-
细胞简介:
人角膜成纤维细胞分离自眼角膜组织;角膜位于眼球前壁的一层透明膜,约占纤维膜的前1/6,从后面看角膜呈正圆形,从前面看为横椭圆形。角膜厚度各部分不尽相同,中央部最薄。角膜有十分敏感的神经末梢,如有外物接触角膜,眼睑便会不由自主地合上以保护眼睛。为了保持透明,角膜并没有血管,透过外界空气、泪液及房水获取养份及氧气。角膜分为五层,由前向后依次为:上皮细胞层、前弹力层、基质层、后弹力层、内皮细胞层。成纤维细胞(Fibroblast)是疏松结缔组织的主要细胞成分,由胚胎时期的间充质细胞分化而来。成纤维细胞较大,轮廓清楚,多为突起的纺锤形或星形的扁平状结构,其细胞核呈规则的卵圆形,核仁大而明显。成纤维细胞功能活动旺盛,细胞质嗜弱碱性,具明显的蛋白质合成和分泌活动,在一定条件下,它可以实现跟纤维细胞的互相转化;成纤维细胞对不同程度的细胞变性、坏死和组织缺损的修复有着十分重要的作用。刚分离的角膜成纤维细胞呈圆形、折光性良好,悬浮于培养基中。30min细胞贴壁,其中部分开始伸出伪足,表现为小的突起;6h后细胞基本贴壁完全,伸展成梭形,胞核清晰,分布较均匀,散在生长,不聚集成团;细胞生长迅速,5-7天即呈融合状态,细胞排列紧密,有的交叉重叠生长,平坦、胞体较大,细胞质透明,细胞核较大,呈椭圆形,颜色淡。细胞融合,并彼此连接成网状;细胞呈突起的纺锤形或星形的扁平分布。角膜成纤维细胞在生理条件下的主要功能包括:构造和维持角膜的正常形态,合成和释放细胞外基质以及组织损伤后及时大量聚集修复损伤组织。
