Abstract

Objective: In this study, we aimed to determine the suitable concentrations of human platelet lysate (HPL) and platelet-richplasma (PRP) for maintaining the in vitro proliferative and angiogenic potential of inflamed dental pulp stem cells.Materials and methods: (LPS)-induced inflamed dental pulp-derived stem cells (iDPSCs) were treated withdifferent concentrations of HPL and PRP (10% and 20%) followed by determination of viability using Alamar Blue assay.Expression of angiogenesis-, adhesion-, and inflammation-regulating genes was also analyzed using RT-qPCR array.Furthermore, expression of growth factors at protein level in the cell culture microenvironment was measured using multiplex assay.Results: Viability of iDPSCs was significantly (p Conclusion: This study suggests that 20% HPL could be optimum to stimulate angiogenesis-related factors in iDPSCs whilemaintaining their viability.Clinical relevance: This data may suggest the potential use of 20% HPL for expanding DPSCs scheduled for clinical trials forregenerative therapies including dental pulp regeneration.
