This study found that EDA and EDAR are expressed throughout cashmere goat fetal development and play a critical role in hair follicle formation by influencing gene expression in fibroblasts and epithelial cells.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This study found that hyaluronic acid increased the size of hair follicle germ-like aggregates and the number of proliferative cells but did not maintain specific markers during the process.

This study found that Hex gene expression patterns in chick embryo dorsal skin during feather bud development suggest a significant role in initiating feather morphogenesis.

This study suggests that exogenous retinoic acid can alter the morphogenesis pathway of developing skin appendages when applied during the placodal stage, leading to changes like feather formation in atypical regions of chick embryos.

This study found that FGF signaling is necessary for the initiation of feather placode development in chicken embryos, with FGF10 being implicated as an early dermal signal in the process.

This review discusses fetal hair follicle development and its importance for determining in utero drug exposure through neonatal hair, but it reports no new clinical results.

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.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

This study observed dynamic changes in CD10 and CD34 expression in fetal and adult human hair follicles during embryogenesis and hair cycling.

This study suggests that Sox13, although dispensable for epidermal development, serves as a marker for early hair follicle development in Sox13-LacZ knock-in mice.

In this research, the authors identify coordinated mechanical forces as crucial for hair follicle development in mammals, with contractile, proliferative, and proteolytic activities facilitating the formation and sectioning of epithelial structures crucial for forming a functional tissue.

This research found that the microtubule catastrophe factor KIF18B plays a crucial role in promoting spindle orientation in keratinocytes, linking this process to cell fate decisions during hair follicle morphogenesis.

Key signals for hair follicle formation were identified.

This study in mice found that MEIS2 expression in mesenchymal dermal cells is crucial for the formation of whiskers and the initial steps of epithelial placode development, independently of sensory nerve innervation or Foxd1 expression.

This study found that the Wnt inhibitor Dkk4 may play a role in regulating hair follicle development through a feedback loop with canonical Wnt signaling pathways.

This study investigated the gene Col19a1, finding its expression is specific to certain cells during hair follicle development in mice, suggesting its potential role in hair follicle morphogenesis.

This study reports that the maintenance and morphogenesis of skin appendages rely on both the dose and duration of ectodysplasin signaling.

This review summarizes current research on molecular pathways, such as Wnt and Notch, that regulate feather follicle development in yellow-feathered broilers, highlighting their potential impact on poultry carcass quality and suggesting areas for future study.

This study found that Eda and activin A regulate Foxi3 expression, which may contribute to the development of hypohidrotic ectodermal dysplasia by affecting Foxi3 activity in ectodermal appendages like hair and teeth.

In this study, mouse sweat gland development relied on a regulatory sequence initiated by Wnt/β-catenin signaling, and disruptions in Wnt, Eda, or Shh pathways led to distinct developmental failures.

This study identified that in pig embryos, the miR-29a-5p/EDAR/lncRNA627.1 ceRNA complex plays a critical role in inhibiting hair placode precursor cells proliferation and regulating hair placode formation through the suppression of EDAR expression, which may provide insights into similar mechanisms affecting human hair conditions.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.

In this study, human placenta extract was observed to enhance the hair-growth-promoting effects of minoxidil and stimulate earlier and prolonged anagen phases in a mouse model.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study found that in hairpoor mice, disruptions in hair follicle stem cell quiescence and signaling pathways lead to disturbed hair cycles, which may help explain alopecia development in Marie-Unna Hypotrichosis patients.

This study identified ectodin as a novel BMP inhibitor that modulates BMP signaling in ectodermal development by interacting with SHH and FGF pathways.

This study identified that Eda-A1 unexpectedly induces placode inhibitors dkk4 and lrp4, indicating the importance of tightly regulated signaling for proper ectodermal organ development.

This study found that the enzyme A20 helps regulate EDAR-induced NF-κB signaling in mice, preventing ectodermal abnormalities like disheveled hair and assuring proper skin and appendage development.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.
