Inkjet Printing: Inkjet Printing of Regenerated Silk Fibroin: From Printable Forms to Printable Functions (Adv. Mater. 29/2015)

Cells “spin” a mineralized spiderweb: BMP-2-loaded silk material is inkjet-printed into a spiderweb pattern on a Petri dish and seeded with mesenchymal stem cells (MSCs) by F. G. Omenetto and co-workers, in work on page 4273. Upon culture in osteogenic media, the osteo-inductive print topographically controls the differentiation of MSCs, resulting in the localized formation of mineralized tissue-like material (stained with Alizarin red in the front cover picture).
