This study concluded that the Wnt signaling pathway does not significantly influence human keratoacanthoma development, but the overexpression of Sox9 suggests alternate signaling involvement.

The document explains the genetic causes and characteristics of inherited hair disorders.

This article discusses the development of skin patterns during embryogenesis and postnatal life, linking them to genetic, environmental, and mathematical factors, but presents no new empirical findings.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

This study found that Polycomb repressive complex 1 is crucial for skin development and stem cell specification, influencing gene activity beyond its known repressor functions.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

This study observed that topical application of maslinic acid stimulated hair growth in mice comparably to minoxidil, possibly through the Wnt/β-catenin pathway and involving ciliary gene activity, highlighting increased levels of trichogenic gene expression and protein levels.

This study on Dorper sheep identified important genetic factors influencing hair follicle development, finding that expression patterns and genes like DBI, FZD3, and ZDHHC21 play a crucial role in wool shedding, which could help improve understanding of mammalian skin-related traits and human hair advancement.

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, the researchers used a transgenic mouse model to examine how Wnt and Shh signalling impact skin tumour development when BMP is inhibited, finding that inhibiting Wnt and Shh pathways significantly slows tumour formation in these mice.

This study found that keratin-associated proteins related to metallothionein and occludin appear in various animals, suggesting they may have roles beyond hair characteristics and were later adapted for hair production.

This study reports that despite rescuing neurulation and skin barrier defects, Grhl3 gene overexpression in mice leads to hearing impairment, hair loss, and other developmental abnormalities, highlighting low tolerance for Grhl3 dysregulation.

This study found that the HoxC gene cluster is crucial for the development of hair and nails in mice, with key regulation by two mammalian-specific enhancers.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

Modern hair restoration techniques can effectively treat hair loss and provide natural-looking results.

A 19-year-old male with delayed puberty was successfully treated for a condition that prevents normal hormone production.

Mice treatments didn't grow hair, a patient treatment may affect immune response, and people with hair loss often feel anxious or depressed.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

This study found that in sheep, the microRNA oar-miR-377 regulates hair follicle development by targeting the SLC24A2 gene, and identified a genetic variation associated with wool quality, suggesting potential markers for breeding.

This review highlights the significance of animal fibers, examining the molecular mechanisms influencing hair follicle development and their impact on fiber quality and quantity, with a focus on studies involving Angora and cashmere goats.

This study found that BMP signaling is involved in regulating melanogenesis, pigment transfer, and melanocyte migration, contributing to our understanding of skin pigmentation mechanisms.

This study investigated novel genetic tools to manipulate hair follicle compartments in mice and found that altering dermal papilla genes can significantly impact hair pigmentation.

This study found that Fgf20 signaling facilitates fibroblast migration and influences dermal condensate cell development during hair follicle morphogenesis by supporting cellular activities such as cell cycle exit and specific cell shape adoption.

This study identified a specific subset of macrophages as a key source of oncostatin M, maintaining hair follicle stem cell quiescence during the resting phase in mice, suggesting a potential target for treating hair disorders.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

This review examines the roles of Smad-4 and Smad-7 in hair follicle differentiation and development through BMP signaling and TGFβ/Activin/BMP pathway inhibition but reports no new experimental results.

This report reviews current advances in hair follicle regeneration for tissue-engineered skin grafts and highlights the feasibility and challenges of creating human hair follicles in this setting, suggesting key bioengineering requirements.

This study found that Hoxc13 gene expression, influenced by melatonin, was associated with hair follicle activity in Cashmere goats, with in vitro evidence suggesting effects on genes relevant to follicle development.

This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.
