Others? Tissue culturing - now what has to be engineered in tissue culturing?
还有别的吗,组织培养技术,组织培养是如何应用生物医学工程学的呢

The extracellular matrix or the collagen gel gives the tissue integrity, and in part, determines its mechanical properties.
细胞外基质或者说胶原蛋白凝胶,使组织成为一个整体,在某种程度上,决定了组织的机械性能

-
often a biologist can discriminate between different kinds of cells that they see in section of a tissue for example, merely by its shape and the characteristics that it has.
生物学家经常可以在组织切片上,仅凭所看见的细胞形状来区分不同细胞,如果举例来说的话,仅通过细胞的形状和特性就足够
-
You get the idea here, is to deliver the gene that you're interested in directly to the tissue where it's being used and in this case, the idea is to introduce a gene that's missing.
但首先你要明确,这种思路是用来将,某个目的基因直接导入,它原本就能被利用的组织中的,此例中是导入一种缺失的基因
-
The other is that this kind of adherence gives the tissue a property that's useful, in this case the property is it can serve as a barrier to nutrients from entering our body.
另外这种黏附,给予组织一种非常有用的属性,这种属性表现为组织成为,营养物质进入身体过程中的屏障

There are cells within your body that are always in the process of division and forming new cells, and sometimes this is for a tissue where cells only have a finite lifetime.

-
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

If I looked within the skin, one of the lower layers of your skin, the connective tissue layer, you'd find many fibroblasts there and they're just waiting in a more rounded shape than this, just waiting to do their job.
如果观察皮肤,更深处的一层细胞,结缔组织层,就能看到许多成纤维细胞,它们平时形状接近圆形,时刻准备着去完成自己的任务
-
What extracellular matrix you have in any particular tissue is there because there's a balance between it being produced by one kind of cell and digested by another, and you're in this sort of state of dynamic equilibrium.
特定组织中,细胞外基质的多少,取决于一个,分泌与降解的平衡,这是一种动态的平衡关系
-
This is introducing a gene, it's a natural gene but it's not - it's a natural gene that's found in humans and is actually expressed all over your body in different levels, but you're concentrating it or over expressing it in one particular region of tissue in order to have a particular effect.
通过导入一个基因,这是一个天然基因但--,是一种于人体内发现的天然基因,在全身细胞中都有不同程度表达,但需要集中在组织的某一特定区域,表达或过表达,才能达到特定疗效
-
It allows us to look not just at the anatomy of what's going on inside your body like an x-ray does, but to look at the chemistry, the biochemistry of what's happening inside a particular organ or tissue in your body.
这种方法不仅能够像X射线那样,使我们从解剖学的角度观察体内的情况,还能了解到,在体内特定的组织和器官中,发生的化学 确切说是生物化学过程
