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，比折纸章鱼有更多的褶皱。

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的方式是由于肾毒素，这些物质往往损坏肾小管上皮细胞。
