This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

This review discusses the life cycle and homeostasis of hair follicles, highlighting their development and the complex signaling between dermal and epithelial cells, but it reports no new clinical results.

This study found that perifollicular vascularization around the dermal papilla adjusts dynamically to physiological changes, with minoxidil enhancing vessel mobilization and aging processes inhibiting it, highlighting potential targets for treating hair loss and skin aging.

This study identified the dermal sheath as a driver of hair follicle regression through muscle contraction, essential for reuniting niches and stem cells to regenerate tissue structure during homeostasis.

This study suggests that cold atmospheric microwave plasma treatment may promote hair renewal by activating β-catenin and YAP/TAZ signaling in human dermal papilla cells.

This study found that epithelial cell metabolism exhibits distinct heterogeneity based on cell density, particularly during the pre-epithelial transition stage where clusters of high and low mitochondrial potential cells emerge.

This pilot study found that intraovarian platelet-rich plasma administration significantly improved the euploidy rate of embryos in infertile women with previous IVF failures.

This study developed and tested continuous implanters for dermal papilla cell aggregates, finding that the bar-cartridge type implanter is the most effective design for continuous cell implantation in androgenetic alopecia research.

This article reviews the stages and regulation of the hair cycle, highlighting molecular regulators involved, but it does not present new research findings.

Using a combination of specific cell cycle regulators is better for safely keeping hair root cells alive indefinitely compared to cancer-related methods.

This study observed that a 3D culture model of hair follicle cells showed an anagen-like phase between days 3 to 6 and transitioned to a catagen-like phase by day 7, highlighting cell differentiation and structural development over time.

This study observed that cultured dermal papilla cells showed distinct functional properties from dermal fibroblasts, including lower proliferation rates, higher adhesion to collagen type IV, and different cell-matrix interactions.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

This study used two-photon microscopy to reveal that the dermal papilla is crucial for hair follicle regeneration and cannot be replaced by neighboring cells, providing new insights into stem cell behavior.

This study found that the expressions of CDK inhibitors p21waf1/cip1 and p27kip1 were higher during the anagen phase compared to telogen, suggesting a role in follicular epithelial cell differentiation.

This study reports a case of cystic panfolliculoma, highlighting the role of epithelial-mesenchymal interactions in its pathogenesis and explaining its histological resemblance to trichofolliculoma.

This study explores the clinical significance of the intravesical prostatic protrusion/prostate volume ratio in diagnosing bladder outlet obstruction but reports no new results.

In this study, injectable platelet-rich fibrin (i-PRF) was found to enhance the proliferative, migratory, and hair-inducing abilities of dermal papilla cells more effectively than platelet-rich plasma through the TGF-β/Smad pathway.

This study suggests that the attachment and interaction between dermal papillae and the hair bulb matrix are crucial for normal hair follicle growth and development in vitro.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.

This study developed the iCOUNT tool, which provides insights into stem cell behavior by tracking cell division events and molecular consequences in human and mouse neural stem/progenitor cells.

This study found that dermal papilla cells from human hair follicles form multi-layered aggregates when cultured in vitro, contrasting with the monolayer growth of dermal fibroblasts.

This report describes an unusual case of proliferating trichilemmal cyst with trichoepitheliomatous change in a young woman, differing from its typical presentation in elderly women.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

This study found that perifollicular vascularization adapts to physiological changes, with minoxidil enhancing capillary growth around the dermal papilla and aging-related factors inhibiting it, suggesting potential interventions for hair loss.

This study identified the dermal sheath as a key component of the hair follicle niche, essential for outer root sheath regression during the hair cycle, highlighting its importance in hair follicle support and regulation.
