Comparison between human cord blood serum and platelet-rich plasma supplementation for Human Wharton's Jelly Stem Cells and dermal fibroblasts culture

We carried out a side-by-side comparison of the effects of Human cord blood serum (HcbS) versus embryonic PRP on Human Wharton's Jelly Stem Cells(hWMSC)and dermal fibroblasts proliferation. Human umbilical cord blood was collected to prepare activated serum (HCS) and platelet-rich plasma (CPRP). Wharton's Jelly Stem Cells and dermal fibroblasts were cultured in complete medium with10% CPRP, 10%HCSor 10% fetal bovine serumand control (serum-free media). The efficiency of the protocols was evaluated in terms of the number of adherent cells and their expansion and Cell proliferation. We showed that proliferation of fibroblasts and mesenchymal stem cells in the presence of cord blood serum and platelet-rich plasma significantly more than the control group (p≤0/05). As an alternative to FBS, cord blood serum has been proved as an effective component in cell tissue culture applications and embraced a vast future in clinical applications of regenerative medicine. However, there is still a need to explore the potential of HCS and its safe applications in humanized cell therapy or tissue engineering.
