Stem cells from human exfoliated deciduous teeth (SHED) can be used as a potential clinical material. But the use of xenogeneic ingredients, especially fetal bovine serum, will increase the risk of zoonotic disease transmission during the use of animal-derived products. Human-platelet-lysate (hPL) was used in human cell expansion with reliability in clinical applications. This study aimed to explore the feasibility and effect of HPL in the cultivation of SHED. We use proteomics to interpret the impact of HPL on the protein profile of SHED. Propagation, differentiation, qPCR and immunofluorescence were used to detect the effect of HPL on SHED.
