This study found that stem cells from mouse dental pulp and vibrissae shared similar marker profiles, but dental pulp stem cells expressed a broader range of stem cell markers, suggesting their potential use in regenerative medicine.

This report presents no new clinical results; it discusses the application of ACell MatriStem™, a porcine urinary bladder-derived extracellular matrix, in wound healing.

This study suggests that fibroblast growth factors FGF-4, FGF-8, and FGF-9 may play redundant roles as signals in epithelial-mesenchymal interactions during multiple stages of tooth development in mice.

This study introduced a theoretical model suggesting that the morphological transition from bud to cap in tooth germ development is driven by mechanical interactions among cells.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

This study found that stem cells derived from root apical papilla in extracted wisdom teeth demonstrated the strongest potential for osteogenic differentiation compared to those from dental pulp and dental follicle.

This review discusses the current understanding of tooth-derived stem cells for periodontal tissue engineering and highlights the heterogeneity and lack of standardization in selecting appropriate stem cell populations; it reports no new experimental results.

This article reviews the use of mesenchymal stem cells and biomimetic scaffolds in regenerative medicine, highlighting promising in vitro and in vivo outcomes, but it reports no new clinical results.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This review discusses how dental pulp stem cells and their derivatives may accelerate skin wound healing by modulating inflammation, promoting angiogenesis, optimizing extracellular matrix structure, and enhancing tissue formation, with implications for translating these findings into therapies for skin and mucosal repair.

Keratin could help create enamel-regenerating toothpaste in a few years.

This study found that the keratin matrix in mammalian hard α-keratins is crucial for maintaining stiffness in water by controlling intermediate filament hydration.

This study suggests that MMP-9 plays a significant role in extracellular matrix remodeling during hair canal formation in mice, as indicated by delayed hair shaft emergence and hair canal development in MMP-9 knockout mice.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This study found that matrix progenitor cells in hair follicles move in a conveyor-belt-like fashion along the dermal papilla, changing their transcriptional states and lineage potential as they differentiate into inner hair follicle layers.

Dental procedures and treatments show promise but need more research for conclusive results.

This study found that the deletion of Med1 in dental epithelia causes a shift from dental to hair tissue development, suggesting the importance of Med1 in maintaining tissue-specific lineage.

This study suggests that a novel micropatterned dermal–epidermal matrix (μDERM) enhances keratinocyte function and epidermal morphology, offering potential improvements in skin substitute design for wound healing applications.

This study found that human dermal papilla cells are embedded in a basement membrane-like extracellular matrix, which is essential for their aggregation and function, as supported by evidence that Matrigel enhances dermal papilla cohesion and gene expression compared to collagen I, which promotes cell dispersion.

This study indicates that porcine acellular dermal matrix may aid hair follicle regeneration in mice by enhancing the expression of SDF-1 and the Wnt3a/β-catenin signaling pathway.

In this study with a rat muscle defect model, decellularized muscle matrix demonstrated better integration, neovascularization, and myogenesis compared to commercially available acellular dermal matrices, and also showed trends toward reduced inflammation and fibrosis after 30 and 60 days.

This study found that mesenchymal progenitor cells from human hair roots seeded onto polymer scaffolds stimulated the production of mineralized proteins, enhancing bone-like structures, with optimal results at a pore size of 35 µm.

This study suggests that although hydroxyapatite gel has strong bactericidal effects, its combination with platelet-enriched blood autoplasm does not enhance antibacterial activity in endodontic treatment for chronic apical periodontitis.

Mutations in keratin genes may link hair disorders to dental decay.

This study observed that a novel extracellular matrix hydrogel made from human fibroblast-derived matrix improved wound healing in animal models, showing significant effects such as hair follicle formation, reduced inflammation, enhanced pro-healing growth factor levels, and interaction with macrophages, compared to traditional collagen hydrogels.

In this study, it was found that dental pulp cells from extracted teeth can be preserved at room temperature for up to five hours without affecting their viability or proliferative potential.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

This study describes previously unknown immune characteristics of the normal human nail, highlighting its similarities to the hair follicle immune system and suggesting an immune privilege in the proximal nail matrix that both provides autoimmunity protection and presents infection susceptibility.
