This study found that Notch signalling promotes differentiation of epidermal cells and acts as a tumour suppressor in the skin by interacting with various pathways and mechanisms.

In this study, different types of catagen in the C57BL/6 mouse model exhibited varying effects on hair follicle melanocytes and melanin distribution, with spontaneous and dexamethasone-induced catagen showing pigment incontinence, while cyclophosphamide-induced catagen retained dendritic melanocytes but increased ectopic melanin.

In this study, researchers found that the curliness of human hair is associated with an asymmetric structure at the cellular level, particularly in the differentiation of the precortex.

Propolis extract can promote hair growth and increase keratin production.

This study observed that human hair macrofibrils predominantly exhibit a double-twist architecture with varying inter-macrofibril angles, advancing insights into their structural organization and mechanical implications.

This study found that a topical hair ampoule containing human follicle stem cells significantly improved hair growth and scalp coverage in women with androgenetic alopecia after four months of use.

This study cataloged human type II hair keratins, detailing their expression and differentiation roles in hair follicles and comparing them with type I keratins to explore keratin-pairing principles.

This study found that BMP-2 activates Dlx3 gene transcription in murine keratinocytes by binding with Smad1/Smad4, suggesting a mechanism for BMP signaling's role in skin and hair follicle regulation.

Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.

This study found that the hHa7 gene in hair follicle trichocytes is the first identified to have its expression directly regulated by androgens, suggesting it as a marker for androgen action on hair follicles.

In this study, N-WASP deficiency in mouse skin was found to cause severe alopecia and disrupt hair follicle cycling by 5 months, highlighting its critical role in skin function and Wnt signaling.

This study demonstrates that dermal white adipose tissue regulates human hair growth and pigmentation through hepatocyte growth factor secretion, highlighting potential therapeutic targets for hair-related disorders.

This paper discusses the multipotency of cyst cells and proposes that understanding molecular circuits in cyst formation could enable engineering of desired stem cell culture phenotypes, but reports no new experimental outcomes.

This study found that Runx3 deficiency in mice affects hair type and shape, suggesting it may regulate hair formation through interactions between dermal and epidermal layers.

This study identified the transcription factor Elf5 as a novel regulator of keratinocyte proliferation and differentiation in skin, with expression elevated in stem/progenitor cell populations, suggesting its potential role in determining cell fate during skin and hair development.

Lustre mutant sheep have normal hair structure and proteins but differ in felting properties.

In this study, researchers found that simple hair clipping in mice induced dynamic plasticity and axogenesis in skin sensory axons, linked to follicular activation and HGF signaling.

This study found that FGF21 suppresses inflammation induced by C. acnes in both human skin cells and mouse models, suggesting potential use in acne treatment.

This study observed that tissue-engineered skin, using VEGF165 gene-modified cells embedded in astragalus polysaccharide-containing 3D printed scaffolds, enhanced early vascularization, and collagen and hair follicle regeneration, leading to improved skin repair in nude mice with full skin defects.
