Alright, as a quick recap, esophageal cancer is the uncontrolled growth of esophageal epithelial cells.

得！快速回顾一下：食管癌指是食管上皮细胞不受控生长。

They're actually tucked into tiny pockets hidden behind the stratified squamous epithelial cells on your tongue.

Not only that, but whole deal is lined with epithelial tissue that has more folds than an origami octopus.

不仅如此，它整个都布满了上皮组织，比折纸章鱼有褶皱。

The other way epithelial cells can necrose is via nephrotoxins, which are substances that tend to damage the epithelial tubular cells.

另一种上皮细胞坏死方式是由于肾素，这些物质往往损坏肾小管上皮细胞。

The CPE specifically targets the tight junctions that connect epithelial cells lining the intestines to one another.

So, during ovulation, the follicle ruptures and releases the egg, which inadvertently leads to epithelial cell damage.

And all of your epithelial tissues are avascular — meaning they don't have a blood supply.

你所有上皮组织都是无血管，这意味着它们没有血液供应。

Now, one of the best studied receptors is the epithelial sodium channel, which, as you might guess, is specific to sodium.
