Silk glands are epithelial tubes made of giant cells. These cells have giant polyploid nuclei (blue) made of thousands of genome copies, and are wrapped around a lumen (yellow), in which they dump silk proteins

🚨New paper! 🚨
@jasminealqassar.bsky.social led this work on the silk glands of the pantry moth.

These two long tubes inside the caterpillar continuously make a ton of silk
How does this special organ work?

Transgenic Plodia larvae expressing the very bright mBaoJin (mStayGold variant) in its silk glands.

Also some gorgeous 3xP3:mCherry staining of larval ocelli and glia.

Preprint alert from the lab
@jasminealqassar.bsky.social led this elegant study of gene expression in the silk glands of our favorite alternative "silk worm", the pantry moth.

Mega-polyploid cells with thousands of genome copies just to express a handful of proteins
