Autologous cultured adipocytes (ANTG-adip) is produced by well-established techniques including cell harvesting from lipoaspirates, expansion of adipose tissue derived stem cells, and differentiation into pure and immature adipocytes. This was an open-label, dose-escalation study. Patients are given subcutaneous injection of ANTG-adip and followed for 12 weeks according to the clinical trial protocol.
