Cancers express particular enzymes that they use to cut through the extracellular matrix to be invasive .
癌症表达特异蛋白酶,通过它穿过细胞外基质,从而进行浸润。
This enables the cell to capture material from the extracellular environment and to respond to cues detected by externally oriented receptors .
这就使细胞能从细胞外的环境中捕获原料,并且回应那些能被外部指向型受体接收的信息。
To obtain single cells for tissue engineering , researchers have to first break tissue apart , using enzymes that digest the extracellular material that normally holds cells together .
