Electrospun hydrogel fibrous scaffolds based on photocrosslinkable gelatin exhibit not only hydrogel properties, but maintain a micro three-dimensional (3D) space structure, as presented by Y. Zhang, H. A. Santos, W. Cui, and co-workers on page 1604617. The structure surpasses conventional hydrogels in promotion of 3D cell growth on and migration into the scaffolds and vascularization, and is good for repairing random skin flaps.
