In this study, researchers found that two dominant haplotypes in the EDA2R/AR intergenic region have likely been shaped by demographic changes and selection during human evolution, particularly notable in African and non-African populations.

This study found that TLR2 expression in hair follicle stem cells is crucial for hair follicle maintenance and regeneration, with TLR2-dependent activation potentially offering new therapeutic approaches for hair loss prevention through mechanisms involving immune pathways and CEP administration.

In this study, the researchers found that a 28-day topical treatment with a postbiotic ferment complex notably altered the scalp microbiome in women with sensitive scalps, increasing certain bacterial species and decreasing others, while also reportedly alleviating symptoms of sensitive skin syndrome in all participants.

This study found that Nubian ibex have developed genetic adaptations in response to their desert environment, including enhanced skin barrier, DNA repair, viral response, and metabolism of toxic compounds.

This study found that keratin-75, discovered in enamel tissue, is secreted by ameloblasts using an unconventional pathway involving the ER-Golgi-Intermediate-Compartment and Golgi, differing from typical cytokeratin localization.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This study found that storing horse hair follicles in RNAlater® at cool or room temperature for up to a week did not affect RNA integrity, suggesting it allows for flexible sample transport without immediate freezing.

This study observed that inflammatory stimuli significantly altered gene expression in rat theca-interstitial cells, affecting pathways related to growth and androgen production, which are central features of polycystic ovary syndrome.

This pilot study suggests that a new preparation of platelet-rich plasma gel may improve symptoms and tissue regeneration in patients with en coup de sabre scleroderma, though further trials are needed to clarify its role.

This review discusses the molecular mechanisms of Hutchinson-Gilford progeria syndrome and evaluates current research trends, available mouse models, and prospects for developing therapies, but reports no new clinical findings.

This study found significant differences in gene expression between newborn and adult skin, with infant skin notably increasing processes related to ECM organization, cell adhesion, and collagen fibril organization.

This study found that activating the Sonic hedgehog pathway in scarring wounds can remodel the dermis to promote hair follicle regeneration, highlighting a potential new approach to enhance healing.

In this study, researchers identified that upon tissue injury in a mouse model, epidermal cells at the wound edge convert to an embryonic-like state with SOX11 and SOX4 playing a central role in modulating epidermal development and cell migration genes.

This study found that JunB, a transcription factor, is crucial for maintaining epidermal-pilosebaceous stem cell homeostasis by regulating progenitor cell behavior and preventing sebaceous gland dysfunction.

This study reports the creation of rat liver stem cell lines that can differentiate into hepatocytes and suggests they might be useful for pharmacological and regenerative medicine applications.

This study found that Hoxc gene expression can reprogram mesenchymal dermal papilla cells, enhance epithelial stem cell regenerative potential, and promote region-specific hair follicle regeneration through Wnt signaling.

In this study, researchers developed a wearable red and blue LED patch and a sprayable fibrin gel to treat infected wounds at home, demonstrating effective infection control and enhanced wound healing in diabetic mice and minipigs.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This study found that basement membrane components and structures in mouse hair follicles are highly specialized for specific inter-tissue interactions, with laminin α5 playing a crucial role in hair cycle regulation and anchoring.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

This study found that in adult mouse skin, reduced levels of histone H3 K4/K9/K27me3 during hair follicle stem cell quiescence are linked to proper tissue homeostasis.

This study found that the transcription factor Gata6 plays a crucial role in adult mouse hair follicle regeneration by promoting the renewal and preventing DNA damage of rapidly proliferating progenitor cells.

This study found that the DNA methylation status of skin samples from cashmere goats was higher during the telogen stage compared to the anagen stage, identifying genes potentially important for hair follicle development and growth.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

In this study, researchers found that deleting Caspase-9 in hair follicle stem cells delayed apoptosis, leading to accelerated wound repair and new hair follicle regeneration by maintaining apoptotic cells as signaling centers.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This study, using multimodal profiling in mice, found that various tissues contain unique γδ T cell subsets adapted to their environment, revealing their functional diversity, lineage relationships, and similarities to CD8+ tissue-resident memory T cells.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents no new clinical results.

This study reports that dynamic interactions between stem cells and their niche, influenced by macro-environmental factors, regulate regenerative behavior in integument pattern formation.

This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.
