Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This article examines differences in aging among ethnic populations and highlights cosmetic procedures specific to skin of color, but reports no new research findings.

This review discusses the potential benefits of activating NRF2 for treating hair follicle disorders linked to oxidative stress and reports no new clinical results.

This study found that Teucrium polium L. subsp. geyrii Maire extract demonstrated a large safety margin in acute and subacute toxicity tests on mice and significantly enhanced wound healing in rats, especially with callus extract, by improving cell proliferation and wound contraction.

This review highlights advances in understanding inflammatory memory in epidermal stem cells, focusing on their capacity to remember prior inflammatory responses and respond more quickly to future stimuli, potentially aiding strategies against skin-related diseases.

This book discusses current research on polycystic ovary syndrome, including diagnosis, management, and the impact of lifestyle changes, without reporting new clinical results.

This study demonstrated that CD19-CAR T cell therapy may promote structural regeneration in the skin of systemic sclerosis patients, as evidenced by histological improvements and fibroblast population changes, suggesting its potential for tissue remodeling in fibrotic diseases.

This review explores the potential for using exosomes in treating autoimmune skin diseases and promoting skin regeneration, highlighting current applications, delivery methods, and ongoing clinical trials while also identifying challenges and future research directions within dermatology.

This review outlines the various fibroblast subsets in the skin dermis, their origins, and their influence on epidermal stem cell behavior, highlighting the role of the local dermal niche in stem cell plasticity.

A 19-year-old male with delayed puberty was successfully treated for a condition that prevents normal hormone production.

This chapter reviews the skin's structure and its clinical relevance, highlighting connective tissue diseases and the potential for novel treatments like protein, cell, or stem cell transfer, but reports no new findings.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.

This review examines chronic telogen effluvium, highlighting its distinctive features and the need for reassurance about its non-progressive nature, but reports no new clinical results.

This study suggests that chronic telogen effluvium may be due to a reduction in the variance of anagen duration, resulting in recurrent hair shedding with minimal long-term hair volume loss.

This review discusses various factors influencing hair growth, including alopecia and hirsutism, and highlights recent advancements in treatment approaches without reporting new clinical results.

This chapter discusses genetic polymorphisms related to phenotypes that differentiate between populations and reports no new results; it highlights the role of DNA technology in understanding human adaptation history.

Early treatment of PCOS in teens is crucial to prevent long-term health issues like diabetes and heart disease.

This study found that children with alopecia areata experienced more stressful life events and excreted higher levels of catecholamines compared to healthy siblings.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

The researchers observed that normal murine hair follicles are direct targets for melatonin, with receptor expression varying throughout the hair cycle, suggesting melatonin's role in hair cycle control.

This study identified several age-related changes in gene expression associated with the extracellular matrix of scalp dermal fibroblasts, which may impact hair follicle maintenance in women over 40.

This study found that women with polycystic ovary syndrome had worse meibomian gland morphology and ocular surface conditions compared to healthy controls, as observed through non-contact meibography.

This review discusses recent insights into the dynamics and regulation of the epidermal differentiation complex during keratinocyte differentiation and reports no new experimental results.

This review analyzed 12 clinical studies on extracellular vesicle therapies, finding potential benefits for skin aging, acne scars, alopecia, and wound healing, but highlighted significant challenges like production standardization and lack of large-scale studies.

This study found that TGF-β2 may enhance collagen expression and spheroid formation in human dermal papilla cells, which could improve their hair inductivity and maintenance.
