This study found that most completely excised basal cell carcinomas in the head and neck were nodular, with a 2.7% recurrence rate, particularly in median areas, likely due to anatomical and histopathological factors.

In this study, dermal papilla cells from rat vibrissae showed potential for treating CNS injuries by secreting neurotrophic factors and promoting neuronal differentiation more effectively than bone marrow mesenchymal stem cells.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

This study found that keratin coatings from human hair may improve the colony-forming efficiency of human mesenchymal stem cells by moderating donor variability, suggesting a potential use in clinical applications.

This study established a stable cell line for CRF1 receptor screening, which can be used to develop functional cosmetics and modulators potentially affecting hair re-growth.

In this study, saw palmetto supplements showed varied effects on cell growth in vitro and did not significantly inhibit growth in the hamster flank organ model despite a notable trend.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

This article discusses the bi-compartmental organization of hair follicle stem cell niches for balancing stem cell cycling and organ growth and proposes similar structures may exist in other adult stem cell niches but reports no new experimental results.

This study suggests that the cell membrane complex in hair cuticles contains hydrophilic regions with disulfide bonds allowing polymer uptake and hydrophobic lamella-like lipid layers.

In this study with mice, simultaneous inactivation of Smad4 and PTEN genes led to rapid development of invasive forestomach squamous cell carcinomas, mirroring human esophageal SCCs.

In this study, the deletion of Smad4 and PTEN genes in mice was associated with rapid and invasive squamous cell carcinoma formation in the forestomach, modeling human esophageal cancer progression.

In this study, researchers found that CCCA in women of African descent is associated with molecular changes, including dysregulation of fatty acid metabolism and fibrosis pathways, suggesting potential targets for new treatments.

In this study, the researchers reported that activin B combined with bone marrow-derived mesenchymal stem cells enhanced wound healing and hair follicle regeneration in rats by promoting cell migration through the ERK and JNK pathways.

This review addresses the role of skin-resident adult stem/progenitor cells in skin homeostasis, disease, and cancer development, and reports no new research results.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This study found that mammary resident macrophages play a key role in mammary tissue development by influencing cell division and maintaining mammary stem cell activity through the TNF-α-Cdk1/Cyclin B1 signaling pathway, highlighting their importance in the mammary stem cell niche.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

This review discusses the role of various genetic regulators in maintaining human mesenchymal stem cell stemness and highlights strategies for ex-vivo expansion, but reports no new clinical findings.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This review discusses current knowledge of keratinocyte stem cell dynamics, including their regenerative roles and potential applications beyond wound healing, but presents no new clinical findings.

This review discusses the regulation and dynamics of the Wnt/β-catenin signaling pathway in development, pluripotency, and cancer, highlighting potential mechanisms and future research directions, but reports no new results.

This study used cashmere goats to reveal distinct intermediate states of dermal papilla cells, each with specific roles in hair growth, shedding, and regeneration.

This symposium reported that DNA damage accumulation in aging stem cells affects genome integrity, highlighting novel mechanisms like Bmi1's role in DNA repair and the involvement of BATF in lymphoid differentiation.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This study found that the microRNA miR-22 is a key regulator of the hair cycle, influencing hair loss by promoting the transition from growth to rest phases and repressing keratinocyte differentiation.

In this study, fibronectin coating on a low-adhesive substratum increased cell aggregation, growth, and motility, enhancing the formation of hair follicle dermal papilla spheroids.

The researchers reported that in hairless mice, epidermal cell division orientations and epidermal thickness varied by body site, with dorsal and ear epidermis primarily dividing parallel to the basement membrane, unlike hind paw and tail epidermis.

This study found that inhibiting the TRPV3 channel may significantly promote hair growth and suggests a potential therapeutic approach for hair loss and related skin diseases.
