So aspirin can reduce pain and swelling in damaged tissues.

The cells of this surrounding sheet have become different in some way and they develop into the placenta and the extra embryonic tissues.
环抱在周围的这一层细胞,已经开始逐渐分化,最终成为胎盘,及额外的胚胎组织
We have tissues like the brain which are assembled to do functions that are different from any other groups of cells in the body.
像我们的脑组织,它们的功能,就截然不同于身体其他部分的细胞功能
Extracellular matrix in most tissues is abundant in collagen and other proteins like collagen.
大部分组织中的细胞外基质,都富含胶原蛋白和其他类似蛋白
and tissues are collections of cells that are working in synchrony for some function.
组织则是一些,同步完成相同功能的细胞的集合
Here I just show tissues at two levels of magnification and when we think about tissues we're going to be interested in a couple of different characteristics.
这里我就给你们展示一下,从两个不同水平看到的组织,当我们研究这些组织时,我们将会对它一大堆不同的特点产生兴趣
The main function of all your cells, and all your tissues, and all your organs is to maintain this homeostasis, which allows you to live in a changing environment.
你所有细胞,所有的组织,所有的器官最主要的功能,就是维护这个内稳态,使你能够以不变应万变
Fibroblasts are specialized cells that exist in connective tissues.
成纤维细胞是,出现在结缔组织中的特化细胞
So action potentials are used by tissues in different ways to send signals from one cell to another or from one end of one cell to another end of the cell.
所以组织以不同的方式利用动作电位,将信号从一个细胞传递到另一个细胞,或从一个神经末梢到另一个神经末梢
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
Now one of the new technologies that's evolving, that we're going to talk about in the last half of the course, is taking cells that have been propagated in this way outside the body and encouraging them to form new tissues.
现在,与此相关的新技术正在蓬勃发展,我们将在这学期的后半部分讨论到它,这项技术,让细胞在体外增殖,并促使它们形成新的组织
We'll talk about cells and how they work, how cells in different parts of the body are different, why, and how they contribute to tissues at a very sort of simple level so that you can understand this as we start thinking about using cells for engineering purposes.
我们将会谈论细胞,它们如何工作,身体不同的部位细胞有怎样的不同,为什么它们有所不同,以及这些细胞如何,以十分简单的方式形成组织,这样当我们开始考虑用细胞,来满足工程目的时,你会更容易理解
