Over time, they become elevated and develop into papules, and then into small fluid-filled vesicles.

然后会进展为丘疹和小而紧张的水疱。

Cells do this by enclosing their contents in tiny sacks, called vesicles.

细胞将自己包裹在一个小袋子里，这个小袋子叫做囊泡。

These tiny little vesicles are found throughout nature.

这些微小的囊泡存在于整个自然界中。

Those vesicles then get transported to an organelle within the cell called the lysosome.

之后囊泡被运输到细胞内被称为溶酶体的细胞器中。

Within 1 to 2 days the vesicles begin to crust over and form scabs.

一到两天内水疱会变硬成痂。

A vesicle is a little ball, like a tiny little balloon.

囊泡是个小球，像个小小的气球。

And the cell has tens of thousands of these little vesicles at any one time.

细胞在任何时候都有数以万计的这些小囊泡。

Their lab had already been doing a lot of work with programming cells to create tiny structures called gas vesicles.

他们的实验室已经对编辑细胞做了大量研究，来制造“气泡囊”这种微型结构。

In a fraction of a second, the mucus vesicles swell and burst, and the protein fibers unravel.

在几分之一秒内，黏液囊膨胀并破裂，蛋白质纤维解开了。

They started by getting this to work on the gas vesicles alone.

他们开始研究，让气泡囊单独经历这一过程。
