Abstract: A display device and a projector are provided. The display device includes a pixel light-emitting panel and multiple color conversion panels. The pixel light-emitting panel includes an N1 number of light-emitting pixel units distributed in an array, and the light-emitting pixel units are driven to emit light through a driver. A first color conversion panel includes an N2 number of first color pixels and an N3 number of first transparent pixels. The first color pixels and the first transparent pixels are disposed relative to the light-emitting pixel units. A second color conversion panel includes an N4 number of second color pixels and an N5 number of second transparent pixels. The second color pixels and the second transparent pixels are disposed relative to the light-emitting pixel units. The lights generated by at least part of the light-emitting pixel units sequentially pass through the first color pixels and the second transparent pixels to achieve the color conversion.

Abstract: Early vascular cells (EVCs), including endothelial cells and pericytes, are generated from hiPSCs. Unlike the isolated endothelial progenitor cells, the differentiated ECs mature and are functional. When encapsulated in synthetic hydrogel, EVCs respond to matrix cues and self-assembled to form three-dimensional EVCs. Moreover, these EVCs respond to hypoxic microenvironment and undergo vasculogenesis to form complex 3D networks.

Abstract: Slow vascularization of functional blood limits the transplantation of tissue constructs and the recovery of ischemic and wounded tissues. Blood vessel ingrowth into polysaccharide-based hydrogel scaffolds remains a challenge. A synergistic effect of multiple angiogenic GFs was established; the co-encapsulation of VEGF plus other growth factors induced more and larger blood vessels than any individual GF, while the combination of all GFs dramatically increased the size and number of newly formed functional vessels. Rapid, efficient, and functional neovascularization may be achieved.

Abstract: Modified polysaccharides and crosslinked modified polysaccharide compositions are described. Methods of using the crosslinked modified polysaccharide compositions to deliver proteins, oligonucleotides, or pharmaceutical agents are also disclosed.
