无需活细胞的制药革命：在试管里造出蛋白质
For decades, making many medicines has meant growing living cells. Scientists fill huge steel tanks with bacteria or yeast, feed them sugar, and wait for the tiny organisms to produce the proteins we need. The method works, but it is slow, fussy, and easily ruined if the cells get sick.
Now researchers are exploring a different path called cell-free biomanufacturing. Instead of keeping cells alive, they break the cells open and take out only the working parts, the molecular machines that actually build proteins. These parts are then put to work directly in a tube.
