Programmed Fabrication of Vesicle‐Based Prototissue Fibers with Modular Functionalities (Adv. Sci. 16/2025)

Vesicle-Based Prototissue Fibers The cover image features the fabrication of free-standing vesicle-based prototissue fibers as if we were writing with a pen. In article number 2409066 by Tomoya Kojima, Kouichi Asakura, Pierangelo Gobbo, and Taisuke Banno, the fibers with well-controlled lengths and diameters are developed, showing modular functionalities such as magnetic manipulation and spatiotemporal directional signal transduction under connection with different fiber modules.
