Outline of Final Research Achievements

Adipose tissue-derived mesenchymal stem cells (ASCs) are useful raw materials for regenerative medicine products. We have established an adipose tissue-derived mesenchymal stromal cell line (ASCL) from ASC, and aim to produce regenerative medical products using platelet-like cells (ASCL-PLC) which differentiated from ASCL. In this study, we developed a large-scale culture method of ASCLs for the manufacture of regenerative medical products. We were able to obtain platelet-like cells (ASCL-PLCs) from ASCLs and to determine specification and test methods of ASCL-PLCs. We believe that the results obtained in this study will accelerate the development of regenerative medicine products.
