Therapeutic Potential of Adipose Stem Cells.

Adipose stem cells (ASCs) have gained attention in the fields of stem cells regenerative medicine due to their multifaceted therapeutic capabilities. Promising preclinical evidence of ASCs has supported the substantial interest in the use of these cells as therapy for human disease. ASCs are an adult stem cell resident in adipose tissue with the potential to differentiation along mesenchymal lineages. They also are known to be recruited to sites of inflammation where they exhibit strong immunomodulatory capabilities to promote wound healing and regeneration. ASCs can be isolated from adipose tissue at a relatively high yield compared to their mesenchymal cell counterparts: bone marrow-derived mesenchymal stem cells (BM-MSCs). Like BM-MSCs, ASCs are easily culture expanded and have a reduced immunogenicity or are perhaps immune privileged, making them attractive options for cellular therapy. Additionally, the heterogeneous cellular product obtained after digestion of adipose tissue, called the stromal vascular fraction (SVF), contains ASCs and several populations of stromal and immune cells. Both the SVF and culture expanded ASCs have the potential to be therapeutic in various diseases. This review will focus on the preclinical and clinical evidence of SVF and ASCs, which make them potential candidates for therapy in regenerative medicine and inflammatory disease processes.
