Transgenic silkworms that weave recombinant proteins into silk cocoons
To utilize this capacity for mass production of useful proteins, transgenic silkworms were generated that synthesized recombinant proteins in the silk gland and secreted them into the silk cocoon. The silk gland is classified into two main regions: the posterior (PSG) and the middle silk gland (MSG). By controlling the expressed regions of the ...

The Journey of Silk: From Cocoon to Couture
Reeling the Silk: Workers then soak the cocoons in hot water to soften the sericin—the protein that holds the silk fibers together. This step allows the delicate fibers to be unwound or "reeled" onto reels. Each cocoon can produce between 600 to 900 meters of silk filament, but it takes threads from several cocoons to make a usable yarn.
