This essay discusses the establishment, maintenance, and role of skin stem cells in tissue homeostasis, wound repair, and their relation to skin cancer, without reporting new experimental findings.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

This chapter reviews the complexity of hair and wool follicle formation, emphasizing the importance of cytological studies to understand the relationship between cellular components.

This study found that simultaneously inhibiting both KLK5 and KLK7 proteases completely rescued skin barrier defects in a mouse model of Netherton syndrome, suggesting both should be therapeutic targets.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

This review outlines a diagnostic framework for clinicians to distinguish different types of inherited ichthyoses and suggests further testing and treatment strategies, but reports no new clinical results.

The study found that severe insulin resistance and premature diabetes are common in patients with PCNT genetic defects, primarily affecting those over four years old, while not impacting early insulin signaling in adipocytes.

In this study, BLIMP1 was found to function in terminally differentiated epidermal cells to maintain homeostasis, rather than defining a sebocyte progenitor population.

This study observed that PAI-2 is consistently expressed in differentiating cells of murine hair and nail, suggesting it may function as a marker of differentiation and possibly protect against premature cell death.

This review discusses recent research and applications of RADA16 and RADA16-based peptide scaffolds in biomedicine, including their roles in tissue repair and drug delivery, but reports no new clinical results.

Human hair follicle cells can become fat and bone cells, useful for therapy.

This study reports that GLP-1 receptors and proglucagon are expressed in the skin of newborn mice, with GLP-1 potentially playing a role in skin development and hair follicle formation.

This study established a new cell line from human hair follicle stem cells that maintains stem cell properties and differentiation capabilities, providing a useful in vitro model for stem cell research.

This review covers the connection between thyroid diseases and skin conditions like alopecia, dermatitis, and vitiligo, and highlights the need for further research on the role of thyroid hormones in skin health.

This study found that the orphan protein Plet-1 is expressed in specific keratinocytes of mouse hair follicles and may regulate keratinocyte interactions with inert tissues by affecting migration and adhesion.

Skin cells can help create early hair-like structures in lab cultures.

This review discusses the identification and roles of different epidermal stem cell types in skin homeostasis and repair, and reports no new experimental findings.
