The significant immunomodulatory capacity of mesenchymal stem cells (MSCs) is increasingly being recognized, making them valuable for the treatment of autoimmune disorders. MSCs influence immune cell behavior during therapy through intercellular communication mediated by extracellular vesicles (EVs). Moreover, MSC-derived apoptotic vesicles (apoEVs) can also exert immunomodulatory functions. This study compared the effects of dental follicle stem cells (DFSCs) and smaller apoptotic vesicles (apoSEVs) derived from DFSCs on the proliferation of peripheral blood mononuclear cells (PBMC), as well as their impact on T cell subpopulations and inflammatory factor expression. The results showed that apoSEVs derived from DFSCs significantly enhanced PBMC proliferation, inhibited Th1, Th17, and Treg cell populations, and reduced IFN-γ and TNF-α expression levels. These findings demonstrate that apoSEVsapoSEVs from DFSCs can effectively regulate immune responses in a manner similar to that of DFSCs themselves.

Purpose: To evaluate the efficacy and underlying mechanism of advanced optimal pulse technology intense pulsed light (AOPT) in low-energy triple-pulse long-width mode (AOPT-LTL) for melasma treatment.
Methods: An in vivo guinea pig model of melasma was established through progesterone injection and ultraviolet B radiation. Three sessions of AOPT-LTL treatment were performed weekly.

Background/aims: Despite medical advances in recent decades, the mortality rate of advanced liver cirrhosis remains high. Although liver transplantation remains the most effective treatment, candidate selection is limited by donor availability and alcohol abstinence requirements. Bone marrow-derived mesenchymal stem cell (BM-MSC) transplantation has shown promise for the treatment of advanced cirrhosis.

The adult human neural stem cell (ahNSC)-conditioned medium (CM) contains various secreted factors that promote tissue repair and neuroprotection. This study aimed to identify the key secreted proteins in ahNSC-CM and investigate the role of tissue inhibitor of metalloproteinases-1 (TIMP-1) in wound healing, angiogenesis, and neuroprotection against oxygenglucose deprivation. Cytokine array and liquid chromatography- tandem mass spectrometry analysis of ahNSC-CM revealed that monocyte chemoattractant protein-1 (MCP-1) and TIMP-1 were highly abundant.

Microfluidic devices offer more accurate fluid flow control and lower reagent use for uniform nanoparticle synthesis than batch synthesis. Here, we propose a microfluidic device that synthesizes uniform iron oxide nanoparticles (IONPs) for highly efficient intracellular delivery. The 3D-printed device was fabricated, comprising two inlets in the T-shaped channel with an inner diameter of 2 mm, followed by a helical mixing channel with a single outlet.

Aim: To investigate the functional significance of mitophagy in age-related osteogenic decline and the underlying mechanisms using in vivo and in vitro models.
Materials And Methods: An alveolar bone defect model in aged mice and a serial passaging-induced ageing model of human periodontal ligament stem cells (PDLSCs) were established. Osteogenic potential in mice was assessed by micro-CT, immunofluorescence, immunohistochemical analyses and histological staining.
