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.
专利号:US-12435312-B2 优先权日:2022-02-28 标 题 :Quantifying cell-derived changes in collagen synthesis, alignment, and mechanics in a 3D connective tissue model 发明人:MORGAN JEFFREY R; WILKS BENJAMIN T 权利人:UNIV BROWN 摘要:Described herein are in vitro quantitative methods directed to 3D extracellular matrix (ECM) organization and mechanics. The methods do not require application of an external force, anchorage, or a scaffolding material in order to culture ECM tissue constructs, and the methods enable quantitative measurements without crosstalk noise from variables attributable to external forces, anchorage, and scaffolding material.
