This review discusses the reuse of molecular mechanisms involved in embryonic skin development for maintaining adult epidermal homeostasis and reports no new results.

This study found that desmocollin 1 is crucial for strong adhesion and barrier maintenance in the mouse epidermis, with its absence leading to skin and hair issues resembling chronic dermatitis.

This review examines the location and markers of hair follicle stem cells, finding that they are primarily located in the bulge region and can contribute to various skin structures, but challenges remain in distinguishing them from their progeny.

In this study, the lack of cathepsin expression in Kaposi's sarcoma lesions suggests a benign hyperplastic origin for these lesions.

This study found that skin computed tomography may effectively identify epidermoid cysts by revealing features consistent with histopathology, potentially serving as a non-invasive diagnostic alternative to biopsies.

This study concluded that early-stage tissue-engineered skin substitutes, developed using skin progenitor cells, had a better graft efficiency and supported hair follicle formation, which may improve wound healing outcomes.

Early-stage skin substitutes improve wound healing and skin structure.

In this case report, a 25-year-old man with nevus comedonicus showed no improvement from keratolytics and topical tretinoin, but had success with surgical excision of the lesions.

This study found that MK6a-deficient mice showed delayed reepithelialization after superficial wounding but not after full-thickness skin wounds, suggesting MK6a plays a role in activating follicular keratinocytes post-wounding.

This study found that NGAL expression in embryonic skin is spatio-temporally regulated and strongly induced in adult skin conditions with dysregulated differentiation, suggesting a role in epithelial differentiation pathways.

Keratins 8 and 14 can help identify and diagnose benign skin tumors.

This study reports that flaky skin mice exhibit skin and nail features that closely resemble human psoriasis vulgaris, suggesting they may serve as a natural model for this condition.

This study found that impaired TCF/Lef1 signaling in mice leads to significant skin barrier defects due to altered lipid metabolism and epidermal differentiation.

This case report describes a 22-year-old woman with a nevoid plaque termed localized follicular hamartoma, characterized by skin-colored papules and specific cellular and structural features.

This study found that calbindin-D9k knockout mice on a maternal vitamin D-deficient and low-calcium diet developed transient alopecia, but a high-vitamin D and calcium diet in mothers reduced this effect.

This report documents the first case of congenital hypotrichosis in a cervid, observed in a 4-month-old male white-tailed deer fawn in South Dakota.

This study found that in hair follicles, androgen receptor expression is stronger in the hair loss and transitional areas compared to the occipital region, suggesting a role in male pattern baldness.

This research investigated the role of EphA1 in embryonic and adult tissues, generating mouse models suggesting potential links to skin and colon cancer, sepsis, and post-traumatic injury.

This study found that the hairless mutant gene in C 57BL/6 mice affects the hair follicle cycle and leads to early thymus degeneration and distinct skin changes.

This study reported the first documented case of congenital hypotrichosis in a white-tailed deer, based on histologic examination of a fawn collected in South Dakota.

This study found that peanut agglutinin binding patterns after neuraminidase pretreatment can help differentiate malignant melanoma from nevocellular nevus in skin specimens.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

This study found that a novel ECM patch combining human fibroblast-derived matrix and PVA hydrogel, seeded with human mesenchymal stem cells, significantly improved wound healing and tissue regeneration in a mouse model.

This study found that the combined ethanolic extract ethosome formulation of Phyllanthus niruri, Zingiber officianale, and Croton tiglium Linné showed better safety and less cytotoxicity for hair growth promotion compared to the petroleum ether formulations.

In this study, researchers found that deficiencies in Gsdma1/2/3 significantly inhibited the initiation and progression of cutaneous squamous cell carcinoma (cSCC) in mice, suggesting GSDMA's role in promoting cSCC proliferation and its potential as a therapeutic target.

This study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

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.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This study found that dermal papilla cells may play a critical role in hair follicle development and cycling by promoting epidermal proliferation and potentially mediating systemic factors that influence follicle behavior.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.
