Abstract (original English)
Cell fate determination and terminal differentiation are shaped by intrinsic molecular programs that coordinate lineage-specific gene expression. In mesenchymal stem cells (MSCs), variability in osteogenic efficiency among distinct tissue sources remains poorly understood and cannot be fully explained by differentiation conditions alone. Increasing evidence indicates that post-transcriptional regulatory mechanisms, particularly those mediated by microRNAs (miRNAs), are closely associated with differentiation outcomes. Here, we investigated whether intrinsic miRNA expression landscapes are associated with lineage-associated differences in late-stage mineralization, in the context of potential donor-related variability of human MSCs. Dental pulp stem cells (DPSCs) and processed lipoaspirate (PLA)-derived MSCs were cultured under identical osteogenic induction conditions and analyzed longitudinally throughout differentiation. Both cell populations fulfilled established mesenchymal phenotypic criteria and successfully initiated osteogenic commitment. However, DPSCs exhibited significantly enhanced extracellular matrix mineralization at mid-to-late stages of differentiation, suggesting divergence at later stages of extracellular matrix mineralization rather than at early lineage commitment. Temporal small RNA sequencing performed at days 0, 7, 14, and 21 revealed progressive remodel
