Summary: The study demonstrates that autologous platelet-rich plasma (PRP) can enhance migration, proliferation, and osteogenic differentiation of dental pulp cells, and this process is strengthened by activating autophagy. Inhibiting autophagy weakens the effects of PRP on cells, while an autophagy activator enhances the promoting effects of PRP.

Summary: The fabrication of PCL/CS-PRF core-shell nanofibrous scaffold via coaxial electrospinning showed improved mechanical properties and sustained release of PRF. In vitro experiments demonstrated higher ALP activity, calcium deposition, and osteogenic differentiation on the scaffold containing PRF. This suggests that PCL/CS-PRF core-shell scaffolds have potential for bone tissue engineering applications.

Summary: Tannic acid was used as a green cross-linker to improve the properties of platelet-rich fibrin (PRF). The results showed that increasing the cross-linker concentration led to changes in scaffold structure, decreased degradation rate, and increased mechanical strength. The cross-linked scaffolds exhibited good biocompatibility and antibacterial effect.

Summary: The study revealed various cell populations in human dental pulp, including dental pulp stem cells, T cells, macrophages, etc., which support each other through growth signals. Pulp cells have the greatest communication with other cell types, while T cells have the least. T cells and endothelial cells play a role in monitoring bacterial invasion through specific receptor expressions. These findings provide insights into the cellular composition of normal dental pulp.

Summary: This study examined the effects of platelet-rich fibrin (PRF) scaffolds and autologous uncultured bone marrow mononuclear cells on osteochondral regeneration in rabbits. The histological characteristics of the PRF scaffolds were assessed, and the results showed that the combination of autologous PRF and uncultured bone marrow mononuclear cells promoted the healing of articular cartilage and subchondral bone in the rabbit knees.

Summary: The aim of this study was to compare chitosan and cobalt incorporated chitosan scaffold in terms of material characteristics, cytotoxicity, and cell adhesion potential. The results showed that cobalt incorporated chitosan scaffold had an amorphous, porous surface and formed chelation with chitosan. XTT analysis demonstrated that the experimental scaffold was non-cytotoxic. Cell seeding assay revealed enhanced cell adhesion to the cobalt incorporated chitosan scaffold at a 1:1 ratio of 100 mL of 100 mu mol/L cobalt chloride solution in 100 mL of 2% chitosan solution.

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: Platelet-rich fibrin (PRF) has potent anti-inflammatory activity, however, the components responsible for this effect are unknown. In this study, we investigated whether the lipid fraction of PRF also exhibits anti-inflammatory properties. Our results show that lipids from PRF can significantly reduce the inflammatory response of ST2 bone marrow stromal cells and primary bone marrow macrophages. These findings suggest that the lipid fraction is at least partially responsible for the anti-inflammatory activity of PRF in vitro.

Summary: In this study, an oxygen-releasing PCL/SP-PVA scaffold was developed and used as a platform for osteogenic differentiation of dental pulp stem cells. The scaffold showed no inhibitory effect on cell growth and provided a suitable matrix for osteogenic differentiation. The results support the use of oxygen-releasing scaffolds as a potential strategy to accelerate bone regeneration.

Summary: The study successfully synthesized phosphate-terminated polyamidoamine dendrimer (PAMAM-PO3H2) and demonstrated their potential as analogs of NCPs for repairing etched dentin. The combination of PAMAM-PO3H2 and PAMAM-COOH shows promise as a feasible therapeutic method for treating dentin caries and dentin hypersensitivity, as indicated by various characterization techniques.

Summary: This study develops a novel contrast agent for noninvasive gastrointestinal tract imaging to detect pH change. The agent, composed of gold nanoclusters and diatrizoic acid, is highly sensitive to acid-base response. The study demonstrates that the agent can detect pH change in the gastrointestinal tract through optical/CT double-modal imaging.

Summary: This study investigated the expression and role of Substance P (SP) in reparative dentinogenesis. It was found that SP contributes to odontoblastic differentiation by binding to the neurokinin-1 receptor (NK1R). These findings provide important insights into the process of reparative dentin formation.

Summary: Programmed response, carrier-free, and multimodal therapy drug delivery systems (DDS) offer promising solutions to address multidirectional cytotoxic effects, inefficient antitumor effects, and severe side effects in cancer therapy. In this study, a carrier-free DDS called IFNa1b-ICG-DOX (IID) was developed using a one-step method without any additional reagents, combining interferon a1b (IFNa1b), indocyanine green (ICG), and doxorubicin (DOX). The system achieved smart and programmed drug delivery through stimuli-responsive controlled release triggered by low pH and near-infrared (NIR) light. In vivo, the larger size and positive charge of IID in low pH environments facilitated its accumulation in tumor tissue, and NIR light could be used to control the release of the drugs, enabling efficient combined chemotherapy, photothermal therapy, and immunotherapy.
