Adipose tissue-derived stromal cells (ASCs) are promising tools for the new therapeutic field of regenerative medicine. Many research teams are intent on producing these cells for therapeutic purposes. The cell production must follow strict rules for safety and for constant quality of the cell product to ensure a reliable effect in patients. These rules are grouped under the generic term Good Manufacturing Practices. In this chapter, we describe the general concepts of ASC production for therapeutic use, explaining new terms such as traceability and qualification. We also introduce general requirements for the installation, equipment, material, and staff for the cell production. Then, we outline a general strategy for building a cell culture process. Finally, as an example, we describe the use of CellStack™ chambers and specific tube sets that allow for producing cells beginning with the stromal vascular fraction under near-closed conditions.
