SYSTEM AND METHOD FOR COATING OR IMPREGNATING A STRUCTURE WITH CELLS THAT EXHIBIT AN IN VIVO PHYSIOLOGIC FUNCTION

摘要

Systems and methods are provided for coating or impregnating a structure with cells that exhibit an in vivo physiologic function. The system includes a specimen holder for holding the structure and cells, as well as a pressure/flow control system that is fluidly coupled to the specimen holder so as to form a flow loop through which fluid traverses. The pressure/flow control system generates and maintains dynamic fluid pressure and flow conditions within the specimen holder and is capable of independently controlling fluid pressure and flow rate in the specimen holder.

1. A method, comprising:
providing a tubular structure; placing cells in contact with the tubular structure; and placing the tubular structure and cells in a system that exposes the tubular structure and cells to dynamic conditions in an ex vivo fluid environment effective to promote the cells to exhibit an in vivo physiologic function, wherein the system comprises:
a specimen holder for holding the tubular structure and cells,a pressure/flow control system that is fluidly coupled to the specimen holder so as to form a flow loop through which fluid traverses, wherein the pressure/flow control system generates and maintains dynamic fluid pressure and flow conditions within the specimen holder and is capable of independently controlling fluid pressure and flow rate in the specimen holder, anda control system for sending control signals to the pressure/flow system.
