Quick answer

Adipose-derived stem cells (ADSC) are adult mesenchymal stem/stromal cells isolated from fat tissue. They can self-renew and differentiate into a limited range of cell types, and they secrete factors that influence surrounding tissue. They are obtained from the stromal vascular fraction and usually expanded in culture.[1][2]

Biology

ADSC belong to the adult stem cell class: multipotent rather than pluripotent.[1] Research on fat graft survival proposes that ADSC support angiogenesis and protect grafted fat through secreted factors rather than by becoming fat cells themselves.[3]

How they are obtained

Fat is harvested by liposuction, processed into SVF, and the adherent stromal cells are expanded in culture. The resulting product is more uniform than SVF but requires a licensed manufacturing environment.[2]

Evidence

Established clinical use of adult stem cells is limited to hematopoietic transplantation; ADSC applications in aesthetics, orthopedics and other fields remain largely investigational.[1]

Regulation and safety

Culture-expanded ADSC are regulated as biological products in most countries. The U.S. FDA warns consumers about unapproved stem cell products.[4]
