什么是破骨细胞

破骨细胞(osteoclast,亦称bone-resorbingcells)是骨细胞的一种,行使骨吸收(boneresorption)的功能。破骨细胞与成骨细胞(osteoblast,亦称bone-formingcells)在功能上相对应。二者协同,在骨骼的发育和形成过程中发挥重要作用。  破骨细胞

骨细胞的基本信息

骨细胞(英语:Osteoblast),名称来自希腊语“ὀστέο”(骨),和“βλαστάνω”(发芽)的组合形式,是具有单核的细胞 ,它们可以合成骨骼。 然而,在成骨作用中,成骨细胞的功能则是连接细胞。 单个细胞不能制造骨骼。 一组有组织的成骨细胞与由一个细胞单元组成的骨骼通常称为骨单位 。成骨细

关于细胞外基质的生物学合成介绍

  哺乳动物中,细胞外基质的成分由成纤维细胞及成骨细胞(Osteoblast)合成,其中前者位于皮肤、肌腱及其它结缔组织中,后者位于骨骼中。胶原蛋白、非胶原糖蛋白等物质在这些细胞中被合成,并通过胞外分泌(Exocytosis)释放到其外部,在胞外完成组装。例如,胶原蛋白在组装前以原骨胶原(Proco
