In this study, researchers showed that Wnt ligands secreted by hair follicle epithelium are crucial for hair follicle regeneration and may be significant for treating hair disorders like alopecia.

This study identified ISX9 as a novel agonist of the Wnt/β‐catenin pathway, which promoted hair regrowth in mice and may offer a therapeutic approach for alopecia.

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 research identified that the constitutive and inducible expression of the Keratin 6 gene in transgenic mice skin is controlled by multiple regulatory elements spread throughout its 5' flanking region.

Wnt and SHH signals together influence hair follicle cell development, offering insights for hair loss treatment.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

This study found that in a population of hair follicles, regenerative cycling stages are regulated by both intrinsic and extrinsic signals, with WNT/BMP signaling mediating interactions among follicles for adaptability.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This review discusses the dual role of the Wnt/β-catenin pathway in mammalian tissue injury, highlighting its potential for both promoting regeneration and contributing to fibrosis, but presents no new findings.

This review discusses the roles of dermal white adipose tissue (dWAT) as an insulator, antibiotic, and regenerative tissue, highlighting its importance in systemic metabolism and immune function, but reports no new clinical results.

This review discusses the role of Wnt/β‐catenin signaling in stem and cancer stem cell maintenance and its involvement in the development and regeneration of various organs, but reports no new experimental results.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.

Four genetic risk spots found for hair loss, with WNT signaling involved and a link to curly hair.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.
