In this study, researchers reported that hair follicle stem cells maintain quiescence through a PIEZO1-dependent mechanism that senses mechanical forces and translates them into localized calcium influx, involving a transcriptional network that regulates cell adhesion and cytoskeleton-related genes.

In this study, researchers demonstrated that follicular tight junctions in porcine skin form a barrier to nanoparticle penetration, particularly in upper regions, which supports its use as a model for human skin.

This study observed that hair follicle cuticular cells undergoing keratinization were significantly thicker than those in a normal hair shaft, due to incomplete loss of cytosol.

This study suggests that the interaction between folliculin and plakophilin-4 (p0071) may play a role in folliculin's tumor suppressor function by regulating RhoA signaling, impacting cell migration and junction formation.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

This study found that in anagen hair follicles, the basement membrane zone components showed decreased expression in the lower hair bulb, with a complete absence of BP230 at the dermal papilla junction, suggesting an incomplete hemidesmosome structure in these regions.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

This study reports that overexpressing the BMP antagonist noggin in mice inhibits eyelid opening by reducing apoptosis and delaying cell differentiation in the eyelid epithelium.

This study found that dual inhibition of BACE1 and BACE2 in mice affects melanosome maturation and causes dose-dependent hair depigmentation without altering retinal morphology.

This study found that deleting the Hes1 gene disrupts hair regeneration by delaying anagen initiation and shortening the anagen phase, suggesting it's crucial for maintaining hair cycle homeostasis.

This article details techniques for eyebrow and eyelash reconstruction surgery with hair follicular unit transplantation but reports no new clinical results; the author describes the advantages over other methods.

This review updates on the development of liposomal carriers for delivering growth factors to improve tissue regeneration and highlights recent efforts to enhance their stability and retention in tissues.

This study outlines the features and diagnosis of Vogt-Koyanagi-Harada disease, highlighting its association with specific genes, its prevalence among pigmented races, and treatment with systemic steroids and immunosuppressants.

This study found that PGF 2α receptors were predominantly present in the inner root sheath of the bulb and stem of human eyelashes during the anagen phase.

This article discusses melanocyte development from neural crest cells and reports no new experimental results; the authors suggest a broader range of functions for melanocytes than previously recognized.

This study found that women with PCOS had significantly prolonged nasal mucociliary clearance time, which may increase their susceptibility to respiratory tract and middle ear infections.

Bardet-Biedl syndrome may include under-recognized skin problems related to its metabolic disturbances.

This study found that Ift20 is essential for hair follicle stem cell identity and hair regrowth, and it regulates keratinocyte migration during wound healing through focal adhesion integrin recycling, independently of ciliogenesis.

This literature review reports that mesenchymal stem cell-derived secretome, including conditioned medium and extracellular vesicles, shows promise as an effective treatment for various diseases in animal and human in-vivo models, with ongoing clinical trials and recommendations for future research discussed.

This study found that topical bortezomib increased cell proliferation in hair follicles and sebaceous glands in mice and may activate hair keratin gene expression through GATA-3 transcription factors.

The researchers reported that disrupting the RPGRIP1L gene in mice impaired desmosome function, causing skin blistering, and their findings suggest that PKCβII inhibition could help treat pemphigus.

This study found that Frizzled genes Fzd3 and Fzd6 are redundantly involved in controlling hair follicle polarity in mice, but operate through distinct mechanisms, highlighting their complex role in hair orientation.

This study found that using ionic liquid for specimen preparation allowed for observation of dermal papilla cells and their cilia in near-living conditions, reducing damage typically caused by conventional preparation methods.

This study found that knocking out vinculin in mouse skin disrupts bulge stem cell quiescence by impairing force generation and mechanical stability of adherens junctions.

This study found that zinc is primarily located in the tails of mature rat sperm, associated with -S-S-bonded structures, and suggests a possible similarity in zinc interactions between sperm keratin and hair proteins.

This study reported that distinct stem/progenitor populations in the ocular surface epithelium have different cell division frequencies and respond differently to injury, with specific spatial compartmentalization and migration behaviors.

This study documents that trichohyalin acts as a multi-functional cross-bridging protein in the inner root sheath of mouse hair follicles, enhancing mechanical strength by linking keratin filaments to the cell envelope.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.
