This study identified ectomesenchyme as a major source of epidermal stem cells in mouse skin, with ectomesenchymal keratinocytes occupying a significant portion of the epidermal stem cell-enriched population.

This case study suggests that atrichia with papular lesions associated with common variable immunodeficiency may follow an autosomal-dominant inheritance pattern, differing from previous reports of autosomal recessive inheritance.

Merkel cells are abundant in facial vellus hair follicles, especially during the anagen phase.

Scalp hair follicle cells help protect and heal skin in certain skin conditions.

This study suggests that the MAEG protein may facilitate epithelial–mesenchymal interactions during hair follicle development by binding to RGD-binding integrins like α8β1.

This case report identifies a new type of hair matrix tumor called "rippled pattern trichomatricoma," distinguished by its unique cell arrangement and differentiation features.

Ectodysplasin-A1 is crucial for developing hair, teeth, and glands.

Retinoic acid causes gland formation instead of hair in mouse skin by altering epidermal and dermal interactions.

This study identified chemokine receptor ligands cxcl10 and cxcl11 as new hair-specific transcriptional targets of the Eda pathway, suggesting chemokine signaling plays a role in primary hair follicle patterning.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This report reviews familial cases of aplasia cutis of the scalp, noting large irregular defects at the vertex or anterior along the sagittal suture in six families.

In this study, subcutaneous injections of murine epidermal growth factor in marsupial pouch young inhibited the formation of hair follicles and associated structures, altering normal follicle development.

This study describes the otolaryngologic manifestations and multidisciplinary management strategies for 12 patients with ectodermal dysplasia, emphasizing the importance of early recognition for effective treatment.

This study identified the distribution of keratin-associated proteins during cornification in the epidermis of reptiles, revealing unique structural characteristics in sauropsid keratin proteins compared to other vertebrates.

This review discusses the relationship between ectodermal alterations and immunodeficiencies, particularly the roles of hyper-IgE syndrome, ectodermal dysplasia, and FOXN1 gene mutations, but it presents no new research findings.

This study found that the Polycomb Repressive Complex 2, particularly its component Ezh2, is crucial in regulating dermal fibroblast differentiation and epidermal keratinocyte proliferation during murine skin development.

This case report highlights a 21-year-old man with severe nodulocystic acne resistant to conventional treatments, who showed moderate improvement with isotretinoin, and discusses its potential link to congenital digital abnormalities and Apert syndrome.

This report describes a case of widespread Porokeratotic eccrine and hair follicle nevus in a 15-year-old woman with keratitis-ichthyosis-deafness syndrome, involving both eccrine ostia and hair follicle infundibula.

This study found that retinoic acid induces epidermal transdifferentiation into mucosal epithelium in both chick and mammalian embryonic skin, involving specific gene expressions and pathways.

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

This article discusses a case study supporting the reclassification of KID syndrome as an ectodermal dysplasia, introducing a potential treatment combination that may alleviate symptoms in affected patients.

In this study, researchers explored how hair follicle orientation is affected in the rosette fancy mouse and found that a mutation in the PCP gene Fzd6 caused reversed hair orientations in the posterior region, leading to the formation of unique whorls.

In this study, retinoic acid treatments induced glandular and feather formation in embryos by altering positional values and activating specific retinoic acid nuclear receptor gene expression.

This article reviews the genetic mutations associated with hypohidrotic ectodermal dysplasia and reports no new clinical results; the authors highlight the roles of EDA gene isoforms and related receptors.

This case report details atrichia with papular lesions in a 4-year-old girl, highlighting specific histological findings on her scalp and other affected areas.

This report details the case of an 11-year-old girl with APECED syndrome carrying a unique homozygous mutation in the AIRE gene, the first of its kind documented.

In this study, ectoderm-targeted transgenic mice with glucocorticoid receptor overexpression exhibited multiple epithelial defects, suggesting the role of NF-kappaB and p63 dysfunction in ectodermal dysplasia syndromes.
