(Chinese Academy of Sciences Headquarters) A research team led by Dr. DU Xuemin at the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences created a new shape-morphing scaffold, enabling programmed deformation from a 2D planar cell-laden structure to a well-defined 3D tubular shape, which facilitated the facile 3D endothelialization of small-diameter vascular grafts.
