Abstract (original English)
Background The dentin-pulp complex (DPC) is composed of the odontoblastic layer and associated stromal components. It serves key functions in immunological homeostasis and tissue regeneration of dental tissues. Human dental pulp stem cells (hDPSCs) have emerged as pivotal cells for DPC regeneration. Current research frontiers primarily focus on developing novel strategies to increase the odontogenic differentiation potential and regenerative efficacy of hDPSCs. This study aims to boost the capacity of hDPSCs to regenerate DPC through mitochondrial transplantation. Methods Mitochondria were isolated from donor hDPSCs and transplanted into recipient hDPSCs (Mito-hDPSCs) in the same passage. Subsequently, cell viability and mitochondrial transplantation efficiency were evaluated via CCK-8, β-galactosidase staining, mitochondrial imaging, and flow cytometry. Furthermore, Mito-hDPSCs' metabolic capacity was assessed by mitochondrial membrane potential assays and cellular oxidative phosphorylation assays. Moreover, Alkaline Phosphatase (ALP) activity, Alizarin Red S (ARS) staining, RT-qPCR, and Western blotting (WB) were performed to assess Mito-hDPSC's odontogenic differentiation potential. Moreover, a nude mouse model was used to assess how Mito-hDPSCs induce DPC regeneration in vivo. RNA-Seq analysis was conducted to examine the expression of signaling pathways in Mito-hDPSCs. In
