Abstract
A recent paper in Cytotherapy presented an interesting soft-tissue augmentation technique that caught our attention. We believe that the method is creative but complicated to practice. We note that the authors used platelet-rich plasma (PRP) solely as the source of growth factors. In fact, PRP itself can serve as a scaffold to carry cells. Considering the unique properties of PRP, we propose an alternative technique that may not only simplify the procedure but also yield promising results. The specific reasons are explained in this letter. In addition, we comment on the use of heparin as an anticoagulant for PRP production.
