This study identified and isolated highly proliferative canine keratinocytes in vitro, finding that follicular keratinocytes showed distinct proliferative capacity and marker expression indicative of putative epithelial stem cells.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

This report describes common skin CT features of rosacea identified using a reflective confocal microscope, facilitating more objective diagnosis but highlights the need for further clinical exploration.

This study found that canine bulge-derived keratinocytes are highly proliferative and can reconstitute pilosebaceous structures, indicating their potential utility in studying human stem cell biology and hair disorders.

This study found that short-term treatment with ROCKi significantly increased keratinocyte stem cell proliferation without affecting their stemness, suggesting a potential safe approach for improving in vitro keratinocyte cultures for clinical applications.

This article reviews a new method to accurately estimate proliferative and migratory epithelial cell numbers post-wounding but reports no experimental findings; the authors suggest its relevance to skin stem-cell biology research.

This case study describes a middle-aged woman diagnosed with a proliferating trichilemmal tumor on her scalp, emphasizing the importance of comprehensive diagnostic approaches and highlighting surgical excision as the primary treatment.

This study found that physoxia improved hair follicle functions in co-cultures of dermal papilla cells and melanocytes by enhancing their biological activities and promoting hair growth and pigmentation.

This report describes the sonographic characteristics of a proliferating trichilemmal tumor in the subungual region, identifying it as a heterogeneous mass with echogenic foci, potentially representing keratin and cholesterol.

In this study, chitosan membranes enhanced melanocyte proliferation and survival by supporting both cell-cell and cell-substrate interactions, unlike polyvinyl alcohol membranes which only facilitated cell-cell interactions.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

This study found that STAT3 directly inhibits the sheep FST gene and cell proliferation, shedding light on the molecular mechanisms of hair follicle development and wool characteristics.

This study identified a novel MTS24-positive murine keratinocyte population with increased colony-forming ability, suggesting these cells may serve as a new reservoir of proliferative progenitor or stem cells in hair follicles.

This study found that hair follicle stem cells from the bulge region in mice and humans can be isolated and cultured to maintain their phenotype and high proliferative capacity, suggesting their potential as an accessible source for tissue engineering and regenerative therapies.

This review discusses the unique characteristics and possible pathophysiology of spiny keratoderma, reporting no new clinical results, but suggests that some therapies might alleviate symptoms.

This study found that nanofat injections significantly improved scar characteristics, including collagen deposition, epidermal thickness, and vascularity, due to its anti-inflammatory and immunomodulatory properties.

This review discusses how fibroblast metabolic processes and life span are influenced by the malate dehydrogenase shuttle system and highlights factors affecting fibroblast proliferative activity, without presenting new experimental results.

This study found that scalp hair follicles had higher expression of cytokeratin 15 and distinct hair layers compared to other body regions, highlighting differences in hair follicle characteristics.

This study found that reconstructed human epidermis from infant skin is more susceptible to UV damage than that from older children, with notable changes in skin cell characteristics during the early years of life.

This publication provides a standardized nomenclature for classifying microscopic lesions in laboratory rat and mouse skin, aiming to harmonize international toxicological research.

This case report documents a rare instance of a trichilemmal cyst occurring on the plantar surface of the foot, highlighting the necessity of histological examination for accurate diagnosis when clinical or radiological presentations are atypical.

This article reviews the skin condition myxedema associated with hypothyroidism, highlighting its characteristic non-pitting, glycosaminoglycan-rich nature, and reports no new results.

This study reported that imaging characteristics of sebaceous nevus vary significantly by age group, revealing dynamic developmental changes that can be effectively identified through dermoscopy and reflectance confocal microscopy, offering noninvasive diagnostic potential.

This study found that hair follicle micro-graft transplantation significantly improved scar remodeling outcomes in 40 patients, with greater reductions in scar volume, lower scar scores, and enhanced skin characteristics compared to punch excision alone, potentially due to activation of the PI3K-AKT pathway.

This study found that Wnt5a expression may suppress cell differentiation and induce an inflammatory response in HaCaT keratinocytes, which could be relevant to psoriasis development.

In this study, PRP significantly accelerated early wound healing in rabbits, with faster closure and improved tissue characteristics compared to controls, although both groups achieved near-complete healing by four weeks.

This study found that the loss of transcription factor Ovol2 in epidermal and hair follicle stem cells leads to migration defects, which are partially improved by deleting the EMT-inducing Zeb1.

This study found that knockdown of PCAT1 inhibited hair follicle regeneration in nude mice by disrupting the miR-329/Wnt10b axis and Wnt/β-catenin signaling, highlighting PCAT1's role in promoting follicle regrowth.

Mechanical stretching can improve or hinder skin regeneration depending on duration.

This study found that cells from the upper hair follicle exhibited more active growth compared to other segments in vitro, suggesting their potential as a source of hair follicle stem cells.
