New Insights into Lidocaine and Adrenaline Effects on Human Adipose Stem Cells

Background Adipose stem cells have gained great interest in plastic and reconstructive surgery with their ability to improve engraftment after fat transfer for soft tissue filling. It is therefore essential to know the effect of the drugs commonly used during the lipoaspiration procedure, such as lidocaine and adrenaline. Indeed, these drugs are infiltrated at the fat donor site for local anesthesia and for reduction of bleeding. This study analyzed the effects of these drugs on the viability of adipose-derived stem cells and on their inflammatory status.
