His research has significant implications for tissue engineering and regenerative medicine.

Latest Patents

One of Yu-I Shen's latest patents is titled "Three-dimensional vascular network assembly from induced pluripotent stem cells." This invention describes a method for generating early vascular cells, including endothelial cells and pericytes, from human induced pluripotent stem cells (hiPSCs). Unlike isolated endothelial progenitor cells, the differentiated endothelial cells mature and exhibit functional characteristics. When encapsulated in synthetic hydrogels, these early vascular cells respond to matrix cues and self-assemble into three-dimensional structures. They also adapt to hypoxic microenvironments, undergoing vasculogenesis to form complex 3D networks.

Another significant patent is "Functional vascularization with biocompatible polysaccharide-based hydrogels." This invention addresses the slow vascularization of functional blood, which limits the transplantation of tissue constructs and the recovery of ischemic and wounded tissues. The patent highlights the challenge of blood vessel ingrowth into polysaccharide-based hydrogel scaffolds. A synergistic effect of multiple angiogenic growth factors was established, demonstrating that the co-encapsulation of VEGF with other growth factors induces the formation of larger and more numerous blood vessels than any individual growth factor alone. This approach may lead to rapid, efficient, and functional neovascularization.
