Abstract
Defects in soft tissue may arise from trauma, chronic diseases, tumor resection, and congenital anomalies. Current practices of autologous grafting and native or synthetic fillers including silicone gel or saline implants have limitations and, like most foreign substances, do not represent long-term solutions. In this chapter, we discuss some of the latest findings in the field of soft tissue regeneration and interventional adipogenesis. We suggest that the field can be advanced by the (1) identification of critical areas of clinical demand and corresponding strategies for different clinical entities; (2) translational approaches that promote angiogenesis and survival of adipose tissue grafts; (3) scale-up of bioengineered adipose tissue grafts; (4) development and adoption of large animal models for testing adipose tissue grafts; and (5) establishment of success criteria for adipose tissue regeneration including the maintenance of volume and shape over time.
