In this study, researchers identified ten key genes involved in the periodic development of hair follicles in cashmere goats, highlighting the importance of the Wnt signaling pathway and cell cycle in this process.

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.

This study found that thymic stromal lymphopoietin (TSLP) promotes hair growth after skin injury by enhancing the proliferation of specific stem cells in hair follicles.

This study observed that deleting ARNT in keratinocytes of mice reduced zigzag hair production and altered hair follicle differentiation, likely by affecting the expression of specific cyclin-dependent kinase inhibitors.

This review discusses various skin conditions affecting women throughout their lives and highlights the pharmacist's role in advising on management and treatment, but it reports no new clinical results.

This research detailed a single-cell atlas showing dynamic hair follicle stem cell states associated with the hair cycle during aging in mice, highlighting differences in chromatin landscape linked to stem cell differentiation and quiescence, and providing a foundation for future exploration of aging reversal.

This study identified genes potentially involved in the development and differentiation of skin appendages in Atelerix albiventris, noting significant enrichment of immune-related genes in hair-type tissues.

In this study, Satura® Rosta remedy was found to significantly increase hair follicle size, hair root volume, and skin thickness in mice, potentially by prolonging the anagen phase, with notable hair regrowth observed in older mice with alopecia.

This study discusses two cases of acneiform skin eruptions associated with the use of the EGFR inhibitor ZD1839 in prostate cancer treatment, emphasizing the need for dermatologists to be aware of potential skin reactions.

This study reviews the development of a mouse model using pyroxylin to induce localized hair growth and shorten the hair cycle's resting phase, suggesting it as a platform for evaluating hair growth treatments, though further research is needed for human application.

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.

The study found that safflower extract may help protect human follicle dermal papilla cells from cisplatin-induced damage, suggesting its potential as an adjuvant in chemotherapy to mitigate hair follicle cell damage.

This study suggests that the growth arrest of nevus melanocytes is not due to oncogene-induced senescence but rather to collective cell interactions, similar to those in normal tissue size regulation.

This study found that hair-type tissues in hedgehogs show higher enrichment of immune-related genes compared to spine-type tissues, suggesting that spines evolved to protect against injuries and infections.

This study found that Ecklonia cava extract increased skin hydration and decreased redness, suggesting potential benefits for protecting and repairing scalp skin from pollutant-induced damage.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This study found that K15 is variably expressed in sheep and mouse hair follicles, with specific patterns suggesting a role in the early stages of keratinocyte differentiation.

In this study, transgenic mice expressing a truncated form of latent transforming growth factor-β-binding protein exhibited altered hair cycles due to increased active transforming growth factor-β, impacting keratinocyte proliferation and hair cycle phases.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

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.

In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.

In this study, constitutive expression of Del1 in mice did not affect wound healing but was associated with increased hair growth following anagen induction.

This study reveals that stem cell descendants in mouse hair follicles can return to their niche to retain stemness and function as primary stem cells for future hair cycles.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.

This article reviews various hair growth and hair loss treatments, noting limited new developments since FDA-approved drugs but highlights recent cosmetic surgery and potential cell-based therapies; it reports no original findings.

This randomized control trial reported that mesenchymal stem cell-derived exosomes significantly increased hair density and thickness in patients with androgenic alopecia, with a mean increase of 35 hairs/cm² over 12 weeks compared to the placebo group, which showed minimal hair density changes.

This study demonstrated that cryogelation of human hair keratin allows the development of 3D scaffolds with tunable properties, supporting cell adhesion and proliferation for potential biomedical applications.
