We talked last time about extracellular matrix and this complex protein-carbohydrate gel that surrounds all cells.
我们上次谈到过的细胞外基质,是一种蛋白和碳水化合物的复合物胶冻,它环绕在细胞周围
It indicates how information flows in cells and indicates a lot about the work that a cell does in maintaining and recreating itself, and maintaining its environment.
这个图展示了信息如何在细胞内传递,以及细胞,在维持 复制自身,和维持其周围环境所需起的作用
They also allow their populations of proteins on the surface of each cell that allow it to interact with its environment, they're receptors and cell adhesion receptors like I talked about last time.
它们同时也使得,这些细胞表面的蛋白质群,使得细胞能够和周围环境进行互动,它们是受体和细胞粘附受体,我上次也说过的
The connective tissue is one of those four main types of tissue, they're supporting material - supporting tissues that surround other cells in the body and give the cell - and give the body much of its mechanical property.
结缔组织是四种主要组织类型中的一种,它们是支持物--是,包围在体内其它细胞周围的支持组织,并赋予身体大部分的机械性能
Well, it's true that it's not stuck to plastic but it is stuck to other materials The other materials that it's stuck to include other cells that surround it and this complex matrix which surrounds all of the cells in our body called extracellular matrix and I'll get to that in just a few moments.
体内的细胞不会贴在塑料片上,但是它们会和别的材料黏联在一起,这些材料包括,细胞和周围细胞间的黏联,细胞同细胞外基质的黏联,我们身体中包围在细胞周围的物质,称为细胞外基质,后面我会详细讲到
