This review discusses the significant role of Wnt signaling in skin development, homeostasis, and disease, highlighting recent advances in understanding its diverse functions, but reports no new experimental results.

In this patient series, researchers observed that subcutaneous scalp injections of adipose tissue enriched with stem cells showed potential as a safe and promising treatment for early genetic hair loss in men and women, based on photographic and quantitative assessments.

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.

This paper reviews the complex anatomy and development of human hair and emphasizes the need to understand these processes for interpreting drug incorporation into hair, with no new clinical results reported.

This abstract omits specific findings and does not provide new research results.

This study explored the regenerative abilities of the African spiny mouse's skin, revealing more robust wound-induced hair follicle neogenesis compared to laboratory mice and highlighting unique features of its hair and wound response.

This study observed that Endoglin is crucial for maintaining correct hair follicle cycling and stimulating hair follicle stem cell niches through feedback interactions involving Wnt/β-catenin and Bmp/Smad signaling pathways in a mouse model.

This study shows that differences in Hoxc gene expression in hair follicle mesenchyme along the body axis contribute to regional variations in mammalian hair growth.

This study found that Endoglin is crucial for proper hair follicle cycling and the activation of hair follicle stem cell niches, based on its role in the feedback crosstalk between Wnt/β-catenin and Bmp/Smad signals.

This study found that carefully engineered hydrogels and asymmetric morphogen gradients facilitated the formation of anatomically relevant skin organoids from iPSC-derived EBs, improving pigmentation and hair follicle generation.

This study found that FGF18 is crucial for regulating hair follicle rest and growth phases, as its absence in mice leads to a shorter resting phase and rapid hair cycling.

This source reviews treatments for androgenetic alopecia, highlighting that combining therapies generally improves effectiveness over single treatments, and discusses emerging drug-assisted delivery techniques aimed at increasing the efficiency of conventional drugs like minoxidil and finasteride.

This study presents a new model for the progression of androgenetic alopecia, suggesting that the loss of attachment between the bulge's stem cells and the arrector pili muscle may contribute to irreversible hair miniaturization.

This study found that epithelial cells in the skin of live mice regulate the density and spatial organization of immune cells, which actively maintain their position despite constant cell turnover.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

This review outlines how peptidyl arginine deiminases (PADIs) and protein citrullination are involved in hair follicle regeneration and inflammatory alopecia, but presents no new clinical findings.

This study found that K15 is variably expressed in sheep and mouse hair follicles, with specific patterns suggesting a role in the early stages of keratinocyte differentiation.

In this study, rat primary thymic epithelial cells demonstrated a clonogenic growth pattern in vitro and were able to integrate into functional thymus or differentiate into skin derivatives, similar to skin multipotent stem cells.

This study presents a new model for androgenetic alopecia progression, explaining diffuse hair loss in women through 3D reconstructions of the arrector pili muscle and its relationship with the hair follicle stem cell niche.

This study suggests that the epigenetic marker 5-hmC may dynamically influence hair follicle bulge activation during anagen growth in mice, warranting further investigation into its role in stem cell regulation.

This study found that histone methylation patterns in hair follicle stem cells differ from those in embryonic stem cells.

This study found that basal cell carcinoma cells differentiate along hair follicle lineages and may be influenced by hair follicle cycle modulators for potential therapeutic targeting.

This study reports that sebaceous glands can regenerate after injury through stem cell plasticity, with hair-follicle-derived stem cells replacing sebaceous gland progenitors and playing a crucial role in the regeneration process, which is dependent on FGFR2 signaling and aided by hair growth induction.

This chapter reviews recent developments in vitiligo research, highlighting the role of melanocyte stem cell differentiation and oxidative stress in its management, but reports no new clinical results.

This study provides a framework for understanding different types of alopecias based on immune privilege collapse at specific follicular sites, revealing distinct patterns in immune effector programs and stromal influences depending on the alopecia type.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This study found that composite skin constructs containing dermal papilla cells promoted better skin healing and hair regeneration in nude mice, highlighting their role in tissue-engineered skin for severe injuries.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This study found that in men with androgenetic alopecia, the expression levels of genes SIRT3 and SIRT7 were reduced, while NFATC1 and PDL-1 were elevated, aligning with patterns seen in aging hair follicles, suggesting these genes' roles in AGA pathogenesis.

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.
