This study reports that during late embryogenesis and early postnatal development, K79-expressing keratinocytes change and die independently of sebaceous glands to form the hair follicle opening, potentially influencing conditions like ingrown hairs or acne.

This study concluded that the inner root sheath inhibits the expression of certain differentiation markers in hair bulbs, with calcium-induced changes paralleling those seen in hair follicle mid-segments.

This study discusses how different modes of regulated cell death in keratinocytes affect skin stem cell niches, and their role in skin inflammation, injury repair, and cancer, based on findings from human dermatological conditions and experimental mouse models.

This review discusses the cornification process of epidermal keratinocytes in forming the skin barrier and reports no new results; it emphasizes the importance for diagnosis and treatment of skin disorders.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

This research presents a comprehensive workflow for producing EMA-compliant autologous keratinocyte-based therapies for wound healing and explores miRNA-mediated regulations in human keratinocytes and adipose-derived mesenchymal stem cells.

This review discusses recent advances in skin penetration mechanisms, specifically focusing on the enhanced understanding of the follicular pathway and its implications for transdermal therapies, immune system targeting, and nanoparticle safety.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

This review describes recent advances in using nanoparticles for drug delivery to hair follicles, with potential applications in treating skin diseases such as alopecia and acne, but reports no new findings.

This review discusses current and emerging drug therapies for treating androgenetic alopecia and alopecia areata, and reports no clinical results; it highlights a need for improved and novel treatments.

This review discusses recent advancements in understanding hair follicles, their disorders, and potential therapeutic opportunities, but it reports no new clinical findings.

This research retrospectively evaluated 92 skin specimens to propose histopathological criteria for diagnosing alopecia areata incognito, distinguishing it from telogen effluvium and androgenetic alopecia.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

In this study, lecithin-based microparticle formulations of minoxidil showed enhanced skin penetration and comparable hair growth effectiveness to commercial products in mice, while minimizing skin irritation often seen with standard minoxidil solutions.

This article discusses the structures surrounding hair follicles and introduces aspects like follicle groups and the dermal sheath, but it reports no new research findings.

This review examines the reliance on formalized and automated protocols in fields like aviation and medicine, suggesting that such approaches may hinder the human capability of mètis needed to handle emergencies and dynamic ambiguities; it reports no new results.

This study found that Tcf3 and Lef1 differently regulate cell differentiation in multipotent skin stem cells, with Tcf3 promoting follicle-like features and Lef1, when modified, promoting sebocyte differentiation.

This review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

Minoxidil promotes hair growth by increasing cell division and DNA synthesis.

This review discusses the use of ablative and nonablative fractional resurfacing for enhanced topical drug delivery in dermatology and reports no new clinical results; further studies are needed to explore these methods.

This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

In this study, researchers analyzed spaceflight data from various sources and found that skin issues during spaceflight are linked to DNA damage, mitochondrial dysregulation, and gene alterations, while also highlighting the skin's adaptability post-flight.

This review highlights that vitamin D is increasingly recognized for its roles in skin health, including treatment of psoriasis, potential applications in conditions like atopic dermatitis, and possible prevention of skin malignancies, as observed in various studies linking low levels to autoimmune skin diseases.

This research highlights the potential of emulgel as an advanced topical drug delivery system, offering improved efficacy for hydrophobic medications in treating dermatological conditions and a range of ailments with its dual release control mechanism of gel and emulsion.

This review discusses autoimmune blistering diseases across species and highlights new treatment efficacy findings and ongoing trials, but it reports no new clinical results.

This study found that proretinal nanoparticles, applied topically, are safe and effective for penetration into hair follicles, enhancing retinoid biological activity in the skin while reducing irritation compared to conventional retinal formulations.
