This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

This study found that topical curcumin can initiate hair growth in mice by acting as a JAK inhibitor but could not fully reverse alopecia areata, likely due to insufficient penetration to deeper skin layers.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This study demonstrates that keratinocyte cell lines derived from cultured hair follicles can fully differentiate in organotypic skin models, offering a minimally invasive alternative to obtaining keratinocytes for research.

This review examines the use of microneedles for treating alopecia areata, highlighting their ability to enhance drug delivery through the skin by bypassing the outer barrier and promoting hair growth with minimal invasiveness.

This review summarizes recent advances in organoid technology for generating tissue models from the three germ layers and reports no new experimental results.

This study found that hair follicle stem cells from hidradenitis suppurativa patients showed alterations in cell cycle regulation and DNA replication, potentially linking genetic predisposition to the skin inflammation characteristic of the disease.

This database provides detailed physiological parameters of porcine skin to enhance the MPML MechDermA Model, improving dermal absorption predictions for human studies in the Simcyp Simulator.

This study observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

This review highlights the potential of microneedle devices in dermatology for conditions like skin aging and autoimmune skin diseases, emphasizing their ability to facilitate targeted drug delivery by creating temporary skin pathways.

Activating the Eda/Edar pathway improves wound healing by enhancing hair follicle growth.

This review discusses nanoparticle-based topical delivery systems for treating skin diseases and presents no new clinical findings; it emphasizes natural polymer-based nanoparticles and future applications like targeted drug delivery.

The researchers reported that autophagy, a lysosome-dependent degradation mechanism, plays a significant role in the cellular remodeling of keratinocyte differentiation in the skin, affecting the properties of the differentiation products by altering cellular components during this process.

This review explores the potential of regenerative cosmetics, specifically engineered skin tissues, for rejuvenating aging skin, healing wounds, and restoring hair, offering promising alternatives to traditional dermocosmetic treatments by promoting collagen production, reducing wrinkles, and regenerating hair follicles.

This study found that understanding the surgical anatomy of the scalp significantly improves outcomes in scalp surgery by reducing complications like unsightly scars and distorted hair patterns.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

In this study, researchers found that p75 neurotrophin receptor signaling affects apoptosis during hair follicle regression in mice, and altering its activity might help manage disorders involving early catagen entry.

This review discusses recent advancements in the study and application of epidermal stem cells for wound healing and tissue engineering, without presenting new experimental findings.

This study demonstrates a varied distribution of keratins in the epidermis of the Malayan pangolin, suggesting evolutionary adaptations related to their distinctive scales.

This research studied the effect of local testosterone propionate applications on rabbit epidermal mitotic activity but reports no new results.

This study reviews iron metabolism in the skin, highlighting how differentially expressed genes regulate iron recycling in the epidermis, and discusses changes in iron metabolism related to skin diseases.

This study developed a multifunctional core-shell fiber dressing that preserves platelet-rich plasma for 180 days, facilitating sustained growth factor release and improved wound healing.

This study found no significant histologic differences in skin structure based on age, sex, or woodchuck hepatitis virus infection status among woodchucks.

This study found that nestin-expressing progenitor cells, capable of becoming ORS keratinocytes, are present in both developing and adult mouse hair follicles.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This study found that in Liaoning cashmere goats, overexpression of the PIP5K1A gene enhances skin fibroblast proliferation, while interference with this gene reverses melatonin-induced proliferation, and PIP5K1A regulates certain miRNA expressions, suggesting a role in improving cashmere yield and quality.

This study suggests that follicular stem cells in the bulge region are not directly targeted in androgenetic alopecia, based on the consistent presence of cytokeratin 15 across scalp samples from affected patients.

This review discusses cases and research on paradoxical hair growth after laser hair removal and explores laser and light therapies for treating alopecia, but reports no new results.

This review discusses topical and intralesional treatments for alopecia areata, providing a management strategy based on patient age and disease severity, but reports no new clinical results.
