Expanded Stem Cells, Stromal-Vascular Fraction , and Platelet – Rich Plasma Enriched Fat: Comparing Results of Different Facial Rejuvenation Approaches in a Clinical Trial
In a previous study, the authors demonstrated that treatment with expanded adipose-derived stem cells or stromal vascular fraction
(SVF)-enriched fat modify the pattern of the dermis in human beings, representing a skin rejuvenation effect. Considering that expanded stem cells require
a cell factor, the authors wanted to assess similar results by replacing them with platelet-rich plasma (PRP), which is easier to obtain and for which an empirical regenerative effect has been already described.
