This study found that AP-2α and AP-2β transcription factors are crucial for maintaining adult skin homeostasis, with their inactivation in keratinocytes leading to impaired differentiation, hair abnormalities, and inflammation, highlighting their key regulatory roles.

This study found that activating β-catenin signaling in embryonic epidermis promoted hair follicle characteristics at the expense of normal epidermal differentiation, leading to early pigmentation and innervation.

This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.

Gene expression in wool follicles changes with growth cycles, offering insights into wool and human hair growth.

This review discusses the role of keratins in providing mechanical resilience to epithelial tissues and highlights recent therapeutic approaches for keratin diseases, but reports no new experimental findings.

In this study, researchers identified nine new sheep keratin genes, highlighting species-specific differences in the expression and compartmentalization of wool-related keratin genes compared to humans.

In this study, the researchers identified key genes with differential m6A methylation involved in cashmere fiber growth, suggesting these modifications may play a significant role in this process.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

This study identified a homozygous frameshift mutation in the HOXC13 gene associated with pure hair and nail ectodermal dysplasia in a consanguineous Syrian family, suggesting crucial roles for HOXC13 in hair and nail development.

In this study, researchers identified novel long non-coding RNAs related to cashmere fineness in goats, highlighting a potential regulatory network involving lncRNA XLOC_008679 and its target gene KRT35.

This study developed an efficient method for isolating and enriching multipotent ovine hair follicle stem cells, which may aid in research on the ovine hair cycle and future wool production.

This study found that specific genetic changes in both coding and noncoding regions may have independently driven the evolution of hairlessness in various mammalian species through accelerated evolution.

In this study, targeting the expression of a keratin KRT5/KRT8 chimeric cDNA in keratin-deficient mice partially restored structural defects in epidermal cells, but did not fully normalize skin health.

This review discusses recent advances in molecular genetics and their impact on the accuracy and understanding of diagnosing inherited skin diseases but reports no new results.

This study suggests that decorin may help maintain hair follicle stem cells and its reduced expression could contribute to age-related hair loss.

This paper presents a protocol for differentiating human-induced pluripotent stem cells into keratinocyte progenitor cells and keratinocytes, suggesting potential applications for hair follicle restoration and burn or ulcer therapy.

This study identified key genes and pathways related to wool follicle development in coarse wool lambs, suggesting epigenetic factors may influence wool sheep domestication and breeding.

Chicken feather gene mutation helps understand human hair disorders.

This review discusses the role of proteomics in understanding skin diseases such as cancers and psoriasis, with findings suggesting cell death and metabolism as major areas of focus, but reports no new experimental results.

This study suggests that the CXCL8 gene may regulate cashmere fineness in Liaoning cashmere goats, providing new insights into the cellular mechanisms of cashmere growth and quality.

This letter to the editor discusses the natural course of epidermolysis bullosa simplex with mottled pigmentation in a Japanese family but does not present new clinical results.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This study found that cashmere has a significantly smaller mean fiber diameter compared to sheep and goat wool, and identified key proteins that may influence this difference.

In this study, researchers used an evolutionary-rate-based method to identify genetic elements associated with reduced hair in mammals, finding a dichotomy between accelerated coding sequences and noncoding regulatory elements influencing hair growth.

This article proposes a hypothesis that KRT75, a protein found in hair follicles, was evolutionarily co-opted by ameloblasts during the development of prismatic enamel in synapsids, but reports no new results.

This study identified four keratin genes associated with hair follicle development that were expressed more highly in super fine wool Xinji sheep compared to fine wool sheep.

This study found that keratinocytes derived from the germinative epithelium of ovine hair follicles have extensive in vitro growth potential, challenging the idea that these cells are solely transit-amplifying.

In this study, researchers found that the cornification process in the nuptial pads of Xenopus frogs involves the expression of the type II hair keratin homolog, krt59, and is regulated by the transcription factor hoxc13, showing similarities to mammalian hair evolution.

This study concluded that human epidermal stem cells cultured in MEM-α and EpiLife media with growth factors show high proliferation potential and plasticity, suggesting potential use in skin regenerative medicine.
