Description
Yichen Wang and six colleagues engineer silkworms to spin silk containing spider egg case protein. Spider egg case silk is hard, water-resistant, and highly moisture absorbent, but spiders cannot be farmed at scale. Silkworms share a similar spinning system, making them ideal bioreactors for spider proteins.
Using a piggyBac transposon system, the team inserted the egg case silk gene from the spider Nephila clavata into the silkworm's heavy-chain expression system. The silk glands produced a new transgenic silk with significantly higher initial modulus and moisture absorption. The authors present the result as a reference for large-scale production of spider egg case proteins, with prospects for environmentally friendly fiber materials.
