 Evidence no. 3 platelet gel from cord blood. A research group led by the investigator proposing the present project has recently developed a novel method PCT no. WO 2010007502 A2, 21 January 2010 to obtain platelet gel from the newborns blood remaining in the placenta after delivery, aka umbilical cord blood or placental blood. The main advantages so far identified in platelet gel derived from cord blood platelets as compared to platelet gel derived from adult platelets relate to the lack of microbiological contamination in the former and to a different profile of growth factors concentrations, the main difference consisting in a higher content of VEGF and lower content of TGF in cord blood platelet gel. Recent modifications performed have led to a procedure in which platelet gel from cord blood can be prepared and stored in a small plastic bag rather than in tubes or dishes, which can be easily cryopreserved, stored, transported to sites of clinical use and applied to the skin ulcer without breaking the sterility chain. This paves the way for a broader use of allogeneic cord blood platelet gel inside and outside hospitals.
