But before we do that, I'd like you to think that at any given time when you're sitting there, in your 70 trillion cells, the extracellular matrix signaling to your nucleus, the nucleus is signaling to your extracellular matrix and this is how your balance is kept and restored.
但在那之前，我需要你们想一想， 你们坐在这儿的每一分每一秒， 你们体内那700亿细胞中的 细胞外基质正向细胞核发出信号， 细胞核也想细胞外基质发出信号回应， 由此你们的机体保持平衡。
