This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This review discusses the use of the feather model to explore tumorigenesis, regeneration, and hormone-dependent growth, highlighting its potential for advancing biomedical research, but reports no novel experimental results.

This article revisits the genetics of pattern baldness but reports no new clinical findings.

This review covers the recent advances in understanding how Turing models may explain various morphogenetic processes, but it reports no new experimental findings.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This study developed a method to culture and maintain chicken feather follicles in vitro, preserving structure and biology similar to their in vivo state, though some gene expression was altered.

This study explored the role of Twist2 in fetal wound healing in embryonic mice, observing that its expression was vital for scarless regeneration and normal hair follicle formation; Twist2 knockdown led to visible scars and defective follicle formation.

In this study, researchers found that the protein Twist2 plays a crucial role in scarless wound healing in early embryonic mouse skins, with its knockdown leading to visible scarring and defective hair follicle formation, suggesting potential therapeutic targets for reducing scars and promoting regeneration.

This article reviews current knowledge on the causes, diagnosis, and medical treatments for androgenetic alopecia, particularly in men, and reports no new findings.

This study demonstrates that patients with benign prostatic hyperplasia have a higher severity and frequency of male pattern baldness compared to a control group.

This review discusses the genetic research developments in androgenetic alopecia, reporting no new clinical results, and highlights the potential for discovering novel therapeutic targets.

This review discusses the perceptions of male pattern baldness by strangers and explores the sociocultural aspects of hair and hair loss but reports no new results.

This article reviews the classification history of androgenic alopecia and highlights the need for further research to find effective hair growth medications.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This study found that melatonin receptor genes play a key regulatory role in the development of goose skin feather follicles during embryonic development.

In this study, alopecia areata patients treated with diphencyprone showed a significant increase in CD8 lymphocytes around hair bulbs, which may be associated with hair regrowth.

This study found that newborn mouse skin organoids can robustly grow hair in vivo, while adult organoids require specific interventions to restore their hair-forming ability.

This study found that bioelectric and biochemical signaling mechanisms coordinate collective cell movement during chicken feather bud morphogenesis, suggesting a potential new angle for research in skin development and wound healing.

This study found that overexpression of R-spondin 3 in a mice model impaired hair morphogenesis and regeneration by reducing hair matrix progenitor cell proliferation, thus disrupting the Wnt pathway's regulation of stem cells.

This study found that the culture conditions, not species-specific differences, determined whether sika deer dermal papilla cells adopted a 3D spheroidal or 2D monolayer growth pattern, influencing their hair-inducing ability.

This article describes techniques for correcting cosmetic deformities caused by older hair flap surgeries, restoring a more natural appearance.

This article reports that a series of techniques can effectively improve cosmetic deformities caused by Juri and Elliott flap procedures, restoring patients to a more natural appearance.

This review discusses recent discoveries about the role of Eda and other TNF-related cytokines in skin appendage development and reports no new experimental results, highlighting developments since the last comprehensive summary in 2003.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

This study developed an in vitro system to analyze human skin progenitor cells' ability to form hair peg-like structures, providing insights for engineering hair follicle organoids.

This review explores fibroblast heterogeneity in the mammalian dermis and suggests potential therapeutic applications by targeting fibroblast subtypes, but reports no new experimental results.

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.

Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.
