This study found that maintaining a low level of Wnt/β-catenin activity is crucial for mammary gland development, as excessive activity inhibits branching and promotes characteristics of hair follicles instead, highlighting its role in skin appendage identity decisions.

This review highlights that skin organoids, advanced three-dimensional models mimicking human skin, are emerging as effective alternatives to traditional culture models and human skin, overcoming limitations of two-dimensional systems and ethical concerns, and are being increasingly used in areas like developmental biology and disease modeling.

This review discusses the use of human-to-mouse xenografting to study human skin processes in vivo, highlighting its importance for understanding skin regeneration and pathology while identifying knowledge gaps and challenges in applying these findings to human skin.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This study found that conditional deletion of Mof in mice resulted in severe defects in skin development, including compromised epidermal differentiation and hair growth, leading to perinatal lethality.

This study reports that despite rescuing neurulation and skin barrier defects, Grhl3 gene overexpression in mice leads to hearing impairment, hair loss, and other developmental abnormalities, highlighting low tolerance for Grhl3 dysregulation.

This article reviews current research on epidermal stem cells and differentiation, presenting models of basal layer composition, but reports no new experimental findings.

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.

This study found that dermal white adipose tissue surrounding human hair follicles enhances proliferation, pigmentation, and hair shaft elongation in an ex vivo setting.

This study found that miR-486 and miR-451 levels were reduced in alopecia areata-affected skin, and delivering their mimics to mice mitigated symptoms by reducing inflammation and immune activity.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This workshop review from the Australian Hair and Wool Research Society discusses findings in cutaneous biology and endocrinology but presents no new research results.

This study found distinct gene expression profiles in the parietal and occipital scalp of individuals with androgenetic alopecia, linked to developmental origins and susceptibility to hair loss, offering insights into genetic and epigenetic factors involved in AGA.

In this study, elevated serum levels of aldosterone and free testosterone, along with increased androgen and aldosterone receptor levels, were associated with early-onset androgenetic alopecia in female patients.

This study proposes a two-step method that may enhance the generation of stem-like epidermal cells with superior proliferation and differentiation potential for skin regeneration.

This study found that certain proteins linked to immune suppression and melanogenesis are associated with repigmentation in vitiligo patients undergoing standard treatment, suggesting these proteins and their pathways play roles distinct from merely reversing skin lesions.

This study highlights the importance of dermoscopic examinations in accurately diagnosing skin cancer, which can be mistaken for benign seborrheic keratosis, emphasizing the need for trained interpretation to avoid missing malignant lesions.

This study found that altering cell culture conditions to form three-dimensional papilla spheroids can restore the ability of human dermal papilla cells to induce hair growth in adult skin.

This study demonstrated that enhancing human skin constructs with hair follicles through engineered cell organization and vascularization improved hair growth in immunodeficient mice, suggesting potential advances for treating alopecia and chronic wounds.

In this study, engineered skin substitutes containing murine dermal papilla cells developed hair follicle-like structures when grafted onto mice, suggesting a model for generating chimeric hair.

This study found that platelet-derived growth factor signaling is crucial for maintaining the hair follicle dermal stem cell pool and supporting their regenerative capacity.

This study established a mouse model for Cushing's syndrome due to a specific Crh mutation, which may help explore the effects of glucocorticoid excess and evaluate treatments for corticosteroid-induced osteoporosis.

This study found that male androgenic alopecia patients using the X5 hair laser device showed a statistically significant increase in hair growth over a 26-week period.

This review discusses recent advancements and ongoing challenges in engineering human skin with appendages using scaffold-free and scaffold-based bioengineering approaches, but it reports no new clinical results.

This article discusses primary cutaneous virilism, focusing on alopecia in women with androgen-dependent skin conditions, and reports no new findings.

This review discusses the fundamental hallmarks of aging as they relate to skin aging and highlights the prominent roles of oxidative damage and the extracellular matrix in photoaging, reporting no new results.

In this study, nifedipine provided rapid symptomatic relief in most patients with severe recalcitrant perniosis, but some experienced side effects that limited dosage and two patients were lost to follow-up.

This study analyzed the genetics of the patchiness phenotype in New Zealand rabbits and found that the gene KRT82, with identified SNPs in its promoter, may serve as a potential biomarker for breeding these rabbits.

This review explores advancements in bioprinting technologies for developing in vitro skin models that replicate immune-mediated skin diseases, highlighting their potential to reduce animal testing and enhance research and product testing capabilities in dermatology.

This study revealed that during avian skin development, complex tissue architecture results from specific cellular flows and mechanical processes that guide feather bud protrusion and elongation, with distinct differences noted in scale development, where rigidity restricts such transformations.
