Introduction: The use of umbilical cord (UC) blood has many advantages in regenerative medicine. Platelet-rich plasma (PRP) is a source of growth factors where its dynamics over time has been evaluated in peripheral blood, however, its evaluation in UC blood has not been studied. Objective: to evaluate the kinetics of PDGF-BB release from PRP obtained from UC blood. Materials and methods: in vitro experimental study. UC blood samples were collected from 6 term deliveries of healthy pregnant women between 18 and 36 years of age who attended the Cayetano Heredia National Hospital in Lima-Peru. Lima-Peru. The samples obtained were centrifuged at 900 g for 10 minutes to prepare the PRP. It was divided into 4 aliquots: (i) without activator and (ii) 1 hour, (iii) 24 hours and (iv) 48 hours, the last three being activated with 10% calcium gluconate (GLu.Ca). The quantification of PDGF-BB was evaluated by ELISA. Results: The means (standard deviations) of PDGF-BB concentration measured at 1 hour, 24 hours and 48 hours were 6127.9 ± 101.6, 6197.5 ± 34 and 6176.8 ± 63.3 pg/ml respectively. The kinetics of PDGF-BB released by PRP showed constant values during the 48 hours. Conclusions: PDGF-BB release from PRP obtained from UC blood was rapidly induced and remained constant and sustained during the first 48 hours after activation.
