Summary: The study aimed to investigate the role of VEGFR-2 in odontoblast differentiation of dental pulp stem cells (DPSCs) by knocking down the expression of VEGFR-2. The results showed that VEGFR-2 is crucial for odontoblast differentiation in DPSCs, and deficiency of VEGFR-2 may impair the differentiation of odontoblast cells.

Summary: This study represents the first assessment of hormetic dose responses by human dental pulp stem cells, focusing on cell renewal and differentiation. The study found that hormetic dose responses are commonly observed in this model, involving a wide range of chemicals including pharmaceuticals, dietary supplements/extracts from medicinal plants, and endogenous agents. The study evaluated the mechanistic foundations, study design considerations, and therapeutic implications of the hormetic dose responses in hDPSCs.

Summary: Human iPSCs are differentiated into HSCs with growth factors for in vitro modeling. The protocol yields iPSC-HSCs with phenotypic and functional characteristics of primary HSCs, suitable for high-throughput in vitro studies. Coculturing iPSC-HSCs with hepatocytes allows for the formation of 3D hepatic spheroids, enabling modeling and drug screening studies.

Summary: This study compared the stem cell properties and pulp regenerative potential of DT-DPSCs and PT-DPSCs from the same individual. The results showed that DT-DPSCs exhibited higher expression of stem cell markers and angiogenic factors compared to PT-DPSCs. DT-DPSC-derived conditioned medium also promoted increased cell proliferation, migration, and angiogenesis. Furthermore, the regenerated pulp tissues in both DT-DPSCs and PT-DPSCs groups were similar. Therefore, DT-DPSCs could be a potential alternative to PT-DPSCs for pulp regenerative therapy.

Summary: This study analyzed the lipid composition of human Dental Pulp-Derived Stem Cells (DPSCs) and investigated the role of lipid rafts during multilineage differentiation. The results showed that mono-unsaturated fatty acids were the most representative species in the acyl chains of DPSCs. Moreover, disrupting lipid rafts prevented AKT activation and lineage-specific mRNA expression during multilineage differentiation, indicating the importance of lipid raft integrity in DPSCs differentiation.

Summary: Magnetic nanomaterials have a growing impact in the field of biology and medicine due to their versatility in drug delivery, cell targeting, and imaging. This study investigates the use of uncoated nickel nanowires as a mechanically-responsive substrate for inducing osteogenic differentiation of adipose derived-mesenchymal cells (ASCs) through magneto-mechanical stimulation. Preliminary results show a significant increase in osteogenic differentiation of ASCs exposed to a specific magnetic field, while adipogenic differentiation remains unchanged.

Summary: This study evaluated the effects of three different bone substitute biomaterials (BSBs) on human dental pulp stem cells (hDPSCs). The results showed that the BSBs did not alter cell proliferation, stemness markers expression, or induce any inflammatory responses. Furthermore, the formulation of the BSBs also influenced the biological properties of the stem cells.

Summary: Obesity is a major global health issue that is reaching concerning levels. Excessive consumption of high-energy foods can lead to metabolic dysfunction and the development of obesity-related diseases. Recent research has revealed the role of tight epigenetic reprogramming in the development of adipocytes, and it is of interest to explore whether the epigenetic mechanisms vary in different tissues. This study investigates the contribution of DNA methylation to the adipogenic potential of dental pulp stem cells (DPSCs) and periodontal ligament stem cells (PLSCs) during adipogenic differentiation in vitro, providing insights into the factors influencing cell differentiation and potential strategies for regulating adipocyte expansion.

Summary: The study revealed that periodontal ligament (PDL) cells exhibit dynamic proliferative characteristics during orthodontic tooth movement-induced tissue remodeling, with proliferative cells likely undergoing further division and contributing to tissue remodeling. Additionally, proliferating cells expressed various molecular markers, indicating the lineage plasticity of PDL cells in vivo.

Summary: Polymeric nanoparticles have been widely used as a delivery vehicle for active compounds in various medical applications due to their biocompatibility, stability, controlled release, and reduced toxicity. This study investigates the interaction between two types of polymeric nanoparticles (PLGA and PLGA/chitosan) and two types of stem cells (OKSCs and SHEDs) in the oral cavity. The results show that nanoparticle uptake depends on stem cell type, incubation time, particle concentration, and surface properties.
