专利号:US-2025043248-A1 优先权日:2023-08-04 标题:Preparation method and use of hydrogel material for growth of blood vessel organoids 发明人:SUN DI; SUN JIAMING; WANG ZHENXING; LEI SHIZE 权利人:UNION HOSPITAL TONGJI MEDICAL COLLEGE HUST 摘要:The present disclosure provides a preparation method and use of a hydrogel material for growth of blood vessel organoids (BVOs). The preparation method of the hydrogel material includes: (1) synthesis of gelatin methacryloyl (GelMA), and (2) synthesis of ns-GelMA-PEO. The hydrogel material may be used for in vitro cultivation of BVOs. The hydrogel material ns-GelMA-PEO prepared by the present disclosure may significantly improve the survival and budding abilities of BVOs. The ns-GelMA-PEO provides a novel solution for in vitro cultivation of BVOs, and may well support the growth and differentiation of organoids.

Such macromers and such hydrogels form additional aspects of the disclosure, as do a wide variety of methods for tuning and for using such hydrogels.
专利号:US-2023096053-A1 优先权日:2019-12-06 标 题:Genetically-targeted chemical assembly: building functional structures and materials in living cells, tissues, and animals 发明人:DEISSEROTH KARL A; BAO ZHENAN; LIU JIA; RAMAKRISHNAN CHARU; KIM YOON SEOK; TOM ARIANE C 权利人:UNIV LELAND STANFORD JUNIOR 摘要:Compositions and methods are provided for genetically modifying cells to guide in situ chemical synthesis of electroactive, conductive, or insulating polymers on plasma membranes, organelle membranes, or subcellular surfaces of cells. In particular, compositions and methods are provided for genetically modifying excitable cells such as neurons, muscle cells, and endocrine cells to guide in situ chemical synthesis of polymers on the extracellular side of the plasma membrane. The subject methods can be used in various applications, for example, to assemble polymers in vivo at targeted locations to modulate electrical conduction and create new electrical conduction pathways, allow cell-type-specific neuromodulation, provide a conductive structure on cells for connection to electrodes, sensors, or other external electronic and electrochemical devices, and create a durable structure to replace damaged tissue for use in regenerative medicine.
