The Age Factor in Postbariatric Body Contouring Surgery Outcome.

Background: Increasing life expectancy will likely lead greater numbers of older patients to seek postbariatric body contouring plastic surgery. The impact of age on body contouring plastic surgery outcome is undetermined.

Methods: A retrospective cohort study of 317 postbariatric body contouring plastic surgery cases was performed.

Cryopreservation of Stromal Vascular Fraction Cells Reduces Their Counts but Not Their Stem Cell Potency.

Unlabelled: Adipose-derived stem cells are derived from the nonfat component of adipose tissue termed the stromal vascular fraction (SVF). The use of freshly isolated autologous SVF cells as an alternative to adult stem cells is becoming more common. Repeated SVF administration for improved clinical outcomes is complicated by the need for repeated liposuction.

Fas-L promotes the stem cell potency of adipose-derived mesenchymal cells.

Fas-L is a TNF family member known to trigger cell death. It has recently become evident that Fas-L can transduce also non-apoptotic signals. Mesenchymal stem cells (MSCs) are multipotent cells that are derived from various adult tissues.
