Abstract

Cell constructs and culture methods are essential tools in tissue engineering. The cell construct should be equivalent to the native cartilage it is intended to replace. Thus, three-dimensional cell constructs are usually composed of a high density of cells and dense extracellular matrix. However, dense constructs suffer from a lack of passive nutrient supply, gas exchange, and removal of degraded debris. We have developed a novel hydrostatic pressure/perfusion culture system that improves the quality of neo-tissues, providing an auto-mated and affordable system for clinical applications. We have also developed a semipermeable membrane pouch that contains a fragile amorphous cell carrier. Although amorphous material is difficult to handle, it is a useful medium in which to deliver cells to the desired site via injection. We evaluated phenotypes of bovine articular chondrocytes embedded in a collagen type I gel enclosed within membrane pouches perme-able to molecules of various sizes. Constant or cyclic hydrostatic pressure was externally applied to the medium phase with a new culture system. Accumulation of cartilage specific matrix was promoted with a 500-kDa cutoff membrane pouch and cyclic hydrostatic pressure at 0.5 MPa, 0.5 Hz. This new method will be useful in the delivery of engineered cells to a desired tissue in regenerative medicine. © 2011 Cognizant Comm. Corp.
