Tissue Repair Mechanisms of Dental Pulp Stem Cells: A Comprehensive Review from Cutaneous Regeneration to Mucosal Healing.

Repairing and regenerating tissue barriers is a key challenge in regenerative medicine. Stem cells play a crucial role in restoring the structural and functional integrity of key epithelial barrier surfaces, including the skin and mucosa. This review analyzes the role of dental pulp stem cells (DPSCs) and their derivatives, including extracellular vesicles, conditioned medium, and intracellular factors, in accelerating skin wound healing.

Tailored Extracellular Vesicles from Dental Stem Cells: Advances in Specific Modifications for Enhanced Therapeutic Applications.

Extracellular vesicles(EVs) derived from dental stem cells have emerged as a key focus in regenerative medicine, owing to their remarkable ability to promote tissue repair and regeneration. Recent advancements revealed that targeted modifications can significantly boost their functional properties, creating new possibilities for the regeneration field. This article provides an overview of the most recent progress in EVs derived from dental stem cells research, with a particular emphasis on diverse engineering strategies such as genetic, chemical, and physical techniques, and their role in enhancing therapeutic performance.

Pathogenesis and therapeutic applications of microglia receptors in Alzheimer's disease.

Microglia, the resident immune cells of the central nervous system, continuously monitor the brain's microenvironment through their array of specific receptors. Once brain function is altered, microglia are recruited to specific sites to perform their immune functions, including phagocytosis of misfolded proteins, cellular debris, and apoptotic cells to maintain homeostasis. When toxic substances are overproduced, microglia are over-activated to produce large amounts of pro-inflammatory cytokines, which induce chronic inflammatory responses and lead to neurotoxicity.

Apoptotic mesenchymal stem cells and their secreted apoptotic extracellular vesicles: therapeutic applications and mechanisms.

Mesenchymal stem cells (MSCs), an accessible and less ethically controversial class of adult stem cells, have demonstrated significant efficacy in treating a wide range of diseases in both the preclinical and clinical phases. However, we do not yet have a clear understanding of the mechanisms by which MSCs exert their therapeutic effects in vivo. We found that the transplanted MSCs go an apoptotic fate within 24 h in vivo irrespective of the route of administration.

Potential of dental pulp stem cells and their products in promoting peripheral nerve regeneration and their future applications.

Peripheral nerve injury (PNI) seriously affects people's quality of life. Stem cell therapy is considered a promising new option for the clinical treatment of PNI. Dental stem cells, particularly dental pulp stem cells (DPSCs), are adult pluripotent stem cells derived from the neuroectoderm.

Association of Systemic Immune-Inflammation Index with Non-Alcoholic Fatty Liver Disease: A Population-Based Cross-Sectional Study.

Background: The aim of this study was to explore the relationship between systemic immune-inflammation (SII) index with non-alcoholic fatty liver disease (NAFLD) in the general population of the United States (U.S.).

[A clinical study of impedance graph in verifying tracheal intubation].

Objective: To evaluate the clinical usefulness of impedance pneumography in determining the tube placement during endotracheal intubation.

Methods: Thirty-six endotracheally-intubated patients for elective operations underwent general anesthesia and endotracheal intubation, and then a second identical tube was inserted into the esophagus under laryngoscopic control. The ventilation circuit was then attached either to tracheal or esophageal tube.
