The transplantation of human stem cells seeded on biomaterials holds promise for many clinical applications in cranio-maxillo-facial tissue engineering and regenerative medicine. However, stem cell propagation necessary to produce sufficient cell numbers currently utilizes fetal calf serum (FCS) as a growth supplement which may subsequently transmit animal pathogens. Human platelet lysate (HPL) could potentially be utilized to produce clinical-grade stem cell-loaded biomaterials as an appropriate FCS substitute that is in line with clinically-applicable practice. The goal of this study was to investigate whether HPL can be successfully used to propagate human mesenchymal stem cells (HMSCs) seeded on clinically-approved collagen materials under clinically-applicable conditions using FCS as a control.
