This study reveals that overexpression of Wnt3 in transgenic mouse skin leads to a short-hair phenotype and cyclical balding due to structural defects in hair shafts, highlighting a role for WNT signaling in hair growth regulation.

This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

This study found that many effects previously thought to be caused by circadian rhythm disruption in Bmal1 knockout mice are actually due to BMAL1's properties unrelated to its clock function.

Hair growth and pigmentation in mice involve specific stages crucial for research.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This study describes a system for generating hair follicles from dissociated cells in mice, suggesting that successful development requires a foundational epithelial platform.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This study found that latanoprost induces significant growth and pigmentation of lashes and ancillary hairs, with effects mirroring both brief and chronic treatments observed in patients and animal models.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This review summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

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 discusses the application of liposomes in dermatology, highlighting their therapeutic value for drug stabilization, skin penetration enhancement, and treatment of hair follicle-associated disorders, but reports no new clinical results.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This review discusses how Western diet may contribute to acne vulgaris through insulin signaling and metabolomic changes, promoting a dietary approach for management, but reports no new experimental results.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

This review summarizes recent research on the skin microbiome's role in acne development and how antibiotic treatments affect skin microbes, but it reports no new clinical results.

This study found that modulating BMP activity in transgenic mice affects the development and characteristics of several ectodermal organs, such as skin, hair, and claws, highlighting a stage-dependent influence on organogenesis.

This review discusses the roles of androgens and androgen receptors in skin-related disorders and suggests that targeting androgen receptors may be a more effective treatment strategy.

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This review discusses the range of long-term complications, including mucocutaneous, ocular, and psychological sequelae, for survivors of Stevens–Johnson syndrome and toxic epidermal necrolysis, but reports no new clinical results.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This study found that red ginseng oil may enhance hair growth and protect skin from UV damage in mouse models by promoting regenerative processes and reducing inflammation.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

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 review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

This review summarizes 15 years of clinical and experimental research advancements in hidradenitis suppurativa, highlighting its recognition as a uniquely healable inflammatory skin disease but reports no new clinical results.
