The same way cells that form the limb become more like muscle cells or skin cells, or the structures that become the limb.
同样的,形成上肢的细胞,变得越来越像肌肉或皮肤细胞,或者上肢的其他结构
If we injected it into a muscle let's say, and your muscle cells took up this plasmid.
比如说,如果我们将其注射入肌肉内,则肌肉细胞就可以吸收这些质粒
Then, your muscle cells would start producing Hepatitis B surface antigen and your immune system recognizing that's a foreign protein would start responding to it.
于是,肌肉细胞将会,开始制造乙肝表面抗原,然后免疫系统就会识别出,那是外来蛋白质并且产生免疫应答
Because muscle can use and frequently is using glucose as a source of energy.
因为肌肉细胞可以利用糖分,通常将糖作为能量来源
The cells that take an electrical signal, which is coming down your nerve and convert it into a muscle contraction work this way, so 'neuro' nerve, muscle junctions act based on ligand-gated ion channels.
依靠相同的工作原理,细胞将来自于神经的,电信号传递到细胞收缩肌中,所以神经和肌肉关节运动,都基于配体门控离子通道
So organs are made up of combinations of tissues where all the tissues are collections of cells that are doing some function, nervous tissue, muscular tissue, epithelial tissue, those are examples of tissues that form organs.
所以器官是由各种组织组合而成,所有的组织都是,具有某些功能的细胞集合,神经组织,肌肉组织,上皮组织,这些都是由组织构成器官的例子
We're going to come back and talk about the action potential a little bit more when we talk about how the heart works, because the heart when its contracting, the muscle cells also use action potentials to initiate contraction.
我们讲心脏工作原理时,会回头再多讨论一点动作电位,因为心脏收缩时,肌肉细胞也利用动作电位来启动收缩
