In this mouse study, severe selenoprotein deficiency in epidermal cells was linked to skin abnormalities, disrupted hair follicle development, and progressive alopecia, highlighting the role of selenoproteins in skin and hair health.

This study demonstrated that a c-Kit-CreER-driven mouse model confirms melanocyte stem cells as a genuine source of melanoma, paralleling human melanoma in heterogeneity and gene signatures.

This study found that combining adult germinative epidermal cells with non-inductive dermal cells can stimulate hair follicle neogenesis, effectively altering the cells' status to enhance induction.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

This study observed that the loss of H3K9me3, via the ablation of Suv39h1, Suv39h2, and Setdb1 in embryonic mouse epidermis, disrupts skin development processes such as keratinocyte differentiation and hair follicle formation, highlighting H3K9me3's crucial role in epidermal morphogenesis.

This study found that donor age and culture medium significantly impact the quality of human full-thickness skin models, with implications for their use as animal model alternatives in research.

This paper discusses advancements in forensic hair analysis, emphasizing a novel DART–HRMS method that improves the accuracy and efficiency of detecting drug use timelines.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.

In this study, co-grafting human keratinocytes with murine dermal papilla-enriched cells produced hair follicle-like structures, but without regular hair formation, suggesting anomalous folliculogenesis.

In this study, lipid peroxides were found to induce apoptosis in hair follicle cells and advance the catagen phase in mice, suggesting a potential mechanism for alopecia development.

This study reports the cloning and sequencing of two type II hair-specific keratin genes, ghHb1 and ghHb6, located on chromosome 12q13, which are expressed during hair growth.

This study found that large excisional wounds in rats across seven strains do not regenerate new hair follicles, unlike in mice, possibly due to differences in epidermal competence and transcriptional profiles.

This study found that bikunin is expressed in human keratinocytes and may play a role in regulating keratinocyte function during mitosis or inflammation.

Fibroblasts can be turned into melanocytes for potential skin treatments.

This study suggests that using ex vivo dermatoscopy can improve the accuracy of scalp biopsy processing by correctly guiding tissue bisection and potentially reducing laboratory costs and turnaround time.

This study highlights a comprehensive approach for authenticating and assessing the quality of herbal medicines using a combination of physiological, morphological, and molecular techniques, including HPTLC, ICP-MS, UV spectroscopy, and DNA barcoding, to ensure the standardization of herbal medicinal products, particularly Eclipta alba.

This study observed unexpected heterogeneity among pigment cells in human scalp hair follicles, identifying immature melanocyte populations outside traditional pigment production zones, raising questions about their potential roles beyond melanin synthesis.

This study found that adipose-derived stem cell extracellular vesicles reduced wrinkles and promoted cell proliferation in UVB-induced photoaging in mice by decreasing oxidative stress and inflammation.

This study found that DPG promoted wound healing in rat skin, with increased collagen I density, particularly evident within the first 14 days after injury.

This study reviewed literature on using vegetable oils to prevent skin aging, highlighting their antioxidant properties and their role in combating free radicals, which leads to extrinsic aging, while also noting Brazil's important contribution to this field with its rich natural resources.

This review examines histochemical and immunohistochemical markers to differentiate apocrine and eccrine sweat glands, highlighting their distinct markers, though it reports no new clinical findings.

This study identified at least four distinct fibroblast populations in adult human skin, each with unique functional properties, suggesting potential therapeutic applications for wound healing and fibrosis-related diseases.

This study suggests that keratin 9 expression in nonpalmoplantar keratinocytes can be induced by signals from palmoplantar fibroblasts, potentially enabling the use of nonpalmoplantar epidermis to treat palmoplantar wounds.

This review compiles epidemiological data on actinic keratoses and suggests promoting strategies like early diagnosis and photoprotection to prevent progression to skin cancer, but it reports no new clinical findings.

This study demonstrated that epidermal neural crest stem cells and bone marrow-derived stem cells migrated toward inflammatory brain lesions in rats and were successfully tracked using noninvasive MRI.

Stem cells in developing hair follicles move to specific areas as they mature.

This study found that Dock5 plays a crucial role in keratinocyte function and wound healing, with its expression reduced in diabetic models but improving healing when restored.

This review presents clinical and preclinical evidence supporting innovative regenerative approaches to treat vitiligo, as existing treatments lack a specific cure and predictable long-term repigmentation outcomes.
