Microvascular Scaffolds: A Biomimetic 3D‐Self‐Forming Approach for Microvascular Scaffolds (Adv. Sci. 9/2020)

Inspired by drying‐driven curling of apple peels, hydrogel‐based micro‐scaled hollow tubules are proposed in article number 1903553 by Yuguang Zhang, Xiaoming Sun, Helder A. Santos, Wenguo Cui, and co‐workers for biomimicking microvessels with diameters of 50–500 μm, which promote microcirculation and improve the survival of random skin flaps. The 3D‐shape‐morphing technique is of great flexibility and potential to lay the foundation for the construction of complex vascular networks, such as Y‐branches, anastomosis rings, and triangle loops.
