Abstract
The methods described herein are for conserving highly expanded cells that have functional properties such as potential for use in neotissue constructs. For example, highly expanded chondrocytes that can be used to construct neocartilage exhibiting functional properties similar to native articular cartilage. The methods and systems feature processes that form functional, human cartilage using cells that have been expanded to at least 1.5×105 times or P3 or greater. This enables a large quantity of engineered cartilage implants to be produced from few cells.
