Cell encapsulation, a strategy whereby a pool of live cells is entrapped within a semipermeable membrane, represents an evolving branch of biotechnology and regenerative medicine. For example, over the last 20 years, male and female gametes and embryos have been encapsulated with or without somatic cells for different purposes, such as in vitro gametogenesis, embryo culture, cell preservation and semen controlled release. Beside that, cell encapsulation technology in alginate, which is a natural biodegradable polymer that mimics the extracellular matrix and supports both cell functions and metabolism, has been developed with the aim of obtaining three-dimensional (3D) cultures. In this context, adipose-derived stromal vascular fraction (SVF) has attracted more and more attention because of its enormous potential in tissue regeneration. In fact, the SVF represents a rich source of mesenchymal cells (ADSCs), potentially able to differentiate into adipocytes, chondrocytes, osteoblasts, myocytes, cardiomyocytes, hepatocytes, and neuronal, epithelial and endothelial cells. These cells are ideal candidates for use in regenerative medicine, tissue engineering, including gene therapy and cell replacement cancer therapies. As long as technological resources are available for large-scale cell encapsulation intended for advanced therapies (gene therapy, somatic cell therapy and tissue engineering), the state-of-the-art in this field is reviewed in terms of scientific literature.
