Your toothpaste contains cellulose gum, the same stuff that plants' cell walls are made of.

你牙膏里含有纤，植物细胞壁也是由纤构成。

Ribs, brisket, pork shoulder, all cuts of meat that have tons of connective tissue, the molecular glue that supports all those muscle fibers.

肋骨，牛腩，肩肉，所有肉块都有大量组织，支撑所有这些肌肉纤分子。

This, Dr Vollrath and his coauthor Mi Ruixin made from a fibrous protein-rich glue of the sort produced naturally by spiders and silkworms.

这是由沃拉斯博士和他合著者Mi Ruixin用一种富含纤蛋白制成，这种是由蜘蛛和蚕自然产生。
