Abstract (original English)

Migration of dental pulp stromal cells (DPSCs) significantly responds to wound healing after pulp injury. Deriving from low compliance characteristics, pulp tissue regeneration is challenging and depends on the microenvironmental signals. Exosomes can maintain and carry bioactive proteins that are crucial in cell communication. Adipose tissue-derived stromal vascular fraction (AD-SVF), a heterogeneous group of progenitor cells, is a promising source of exosomes. Discover the impact of exosomes derived from an adipose-derived stromal-vascular fraction (AD-SVF Exo) on human dental pulp stromal cells (hDPSCs) migration. Methods: In-vitro design involving AD-SVF Exo applied to hDPSCs cultivated until 80% confluence and 3rd-4th passage. AD-SVF Exo isolation through size exclusion chromatography (SEC). The AD-SVF Exo was characterized using Nanoparticle Tracking Analysis (NTA) and flow cytometry assays. hDPSCs were exposed to AD-SVF Exo (0% as the control group, 0.1%, and 1% as the experimental group), subjected to a scratch wound assay, and observed at 6, 24, and 48 h. hDPSCs cultured expressed mesenchymal stem cell mesenchymal stem cell (MSC) markers and formed loose colonies with characteristic spindle-shaped morphology. AD-SVF Exo consisted of marker proteins CD9 and CD63, and NTA measurement demonstrated a diameter of 103 ± 24 nm in diameter with 1,6 x 10 8 particles/ml. Based o
