This study found that in androgenic alopecia, the arrector pili muscle degenerates and is replaced by fat, unlike in normal skin or telogen effluvium.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

The document describes a woman with familial Parkinson's disease due to a genetic mutation, showing severe symptoms and poor response to treatment, and suggests finasteride may help reduce symptoms in Tourette syndrome.

This retrospective study found that a hairline-lowering technique effectively advanced the female hairline by an average of 2.1 cm with high patient satisfaction and minimal complications over 20 years.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This study observed that hair follicles in hair loss patients had increased levels of Propionibacterium acnes, potentially linked to elevated immune response gene expression in miniaturized hair follicles.

In this randomized clinical trial, the authors reported that adipose-derived stem cell constituent extract topical solution increased hair density and thickness in patients with androgenetic alopecia over 16 weeks compared to placebo.

This study found that using ectopic expression of CD24 is a promising approach for selecting genetically modified human epidermal stem cells for safe cutaneous gene therapy in cancer-prone conditions.

This study found that extracellular ATP released from UVB-irradiated keratinocytes promotes melanin production through the P2X7 receptor, indicating a role for ATP-P2X7 signaling in UV-induced melanogenesis.

This review detailed the types and mechanisms of injectable "skin boosters" and evaluated their effectiveness and safety for mitigating age-related skin changes, providing insight into their use in contemporary dermatological practice.

This review discusses the integration of ultrasound in dermatology for improved lesion visualization and diagnosis, highlighting recent technological advancements like handheld devices and high-frequency probes, and reports no clinical results.

This review discusses skin diseases in transgender patients receiving gender-affirming hormone therapy and procedures, highlighting unique conditions and the underdiagnosis that affects their quality of life and mental health.

This study found that certain keratin gene mutations associated with pachyonychia congenita are linked to altered enamel structure and increased risk of dental caries.

This study identified a gene expression signature in mouse embryonic dermal fibroblasts that depends on Wnt/β-catenin activity, potentially influencing dermal fibroblast identity and function.

This study utilized magnetic resonance imaging to noninvasively visualize and differentiate skin structures in rat skin, finding a significant correlation between MRI data and histological areas.

This study found that treating acute and chronic canine skin wounds with adipose-derived mesenchymal stem cells significantly improved healing and reduced inflammation, suggesting potential benefits for human wound care.

This study developed a portable electrospinning device that mimics hair for cosmetic thickening in a mouse model, showing performance comparable to benchtop models with added safety and cost benefits.

This study found that acne lesion formation involves early hyperkeratinization and inflammation around hair follicles, creating a self-sustaining cycle that may progressively worsen acne.

This source reviews Japan's extensive 2014 reforms and investments in regenerative medicine, exploring the government's initiatives to accelerate stem cell research while maintaining safety and efficacy.

This study found that reduced cell cohesiveness in eccrine sweat gland outgrowths contributed to delayed wound healing in elderly skin compared to younger skin.

The researchers reported that hair follicle germinative epidermal cells can form complex structures when associating with papilla cells in culture, unlike other types of epidermal cells.

This study found that extracellular vesicles from low-passage dermal papilla cells may activate hair growth by delivering miR-140-5p, which downregulates BMP2 signaling, suggesting potential therapeutic targets for alopecia.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study highlights the urgent need for health policies in Korea that focus on diseases with rising burdens and groups experiencing high health burdens, as a step toward improving population health and achieving health equity.

This review discusses the potential of bioprinting technology in cosmetology, particularly for improving skin functions like pigmentation restoration and hair follicle development, but reports no new clinical findings.

Finasteride significantly reduced tics and obsessive-compulsive symptoms in patients with Tourette syndrome.

This study found that a serum-free DMEM-F12 medium with 45% oxygen best supports in vitro development and differentiation of human fetal skin, closely mimicking the in vivo state.

This study found that 3D cultured hair follicle-like constructs, which include keratinocytes and dermal papilla cells, showed improved gene expression and cell interactions relevant to hair follicle development.

This study reported that a novel chitosan/polyvinyl alcohol nanofiber sponge effectively enhances the hair follicle-inducing ability of dermal papilla multicellular spheroids in a mouse model.

This study concluded that dermatology has made the most significant contributions to noninvasive and minimally invasive cosmetic procedures, while other specialties have also provided important literature in this field.
