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.

This study found that nevoid basal cell carcinomas originate in the epidermis and the upper part of the hair follicle, showing similarities to nonnevoid basal cell carcinomas.

Congenital triangular alopecia can occur outside the typical fronto-temporal region.

The researchers in this study identified a new subpopulation of dermal fibroblasts in neonatal murine dermis marked by EGFR, which they report contributes to hair follicle regeneration through the promotion of IGF1, potentially aiding in wound-induced hair follicle neogenesis.

This study found that the presence of premature desquamation of the inner root sheath in noninflamed hair follicles is a relatively specific marker for diagnosing central centrifugal cicatricial alopecia.

A rare skin reaction from cancer treatment was successfully managed with topical treatments and antihistamines.

This case report describes a 5-year-old boy with a solitary patch of hair loss, potentially linked to a fungal infection after antibiotic treatment showed minimal effectiveness.

This study introduces the term "hair matrix cyst" for a cyst with both pilomatricoma and epidermal cyst characteristics, highlighting its potential for misdiagnosis among similar skin conditions.

This review discusses the genetic basis of ectodermal dysplasia, highlighting that identification of gene pathologies enhances diagnosis and supports prenatal DNA testing, but it reports no new clinical results.

This case report details a rare instance of eruptive vellus hair cysts in a 12-year-old male, highlighting its atypical morphology and axillary distribution, which has not been previously documented.

This study found that KROX20 is crucial for hair follicle development and epidermal homeostasis, as its deletion in skin epithelial cells led to hair loss and increased epidermal thickness.

This study identified a 195 bp duplication in crested chickens that causes large crest feathers and can be associated with cerebral hernia in some breeds, but not all.

This study identified a homozygous missense mutation in the KRTHB5 gene linked to pure hair–nail ectodermal dysplasias in a large consanguineous Pakistani family, providing new insights into the condition's molecular pathogenesis.

LRIG1 protein affects hair growth by regulating skin receptors, leading to hair loss when overexpressed.

This study demonstrates that incorporating human neopapilla into reconstructed human skin can initiate hair follicle morphogenesis by stimulating epidermal invagination and maintaining follicle-inductive properties in vitro.

Type I keratin genes are closely linked to the rex locus on mouse chromosome 11, affecting hair development.

This study reported that human induced pluripotent stem cell-derived skin organoids, used to model epidermolysis bullosa, have an epidermal-dermal junction largely lacking type VII collagen, which is important for skin structure.

This case report describes a 22-year-old Asian man with erosive pustular dermatosis of the scalp, whose lesions improved after treatment with topical tacrolimus and oral isotretinoin.

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 study found that Krox20 marks a diverse stem cell population in mouse hair follicles, which significantly contributes to the interfollicular epidermis and regulates epidermal homeostasis.

The study suggests that nestin-expressing progenitor cells can differentiate into outer root sheath keratinocytes in hair follicles, indicating distinct progenitors for different hair follicle and epidermal components.

This case report describes the occurrence of eruptive vellus hair cysts in twin patients, adding to the literature on this dermatological condition.

This commentary discusses the role of the epidermis in hair follicle induction and reports no new research findings.

This study reports that in mice, CaR plays a critical role in sensing the epidermal Ca2+ gradient, influencing keratinocyte differentiation, and affecting epidermal development.

This study found that Hoxc13-/- rabbits exhibit complete hair loss on the head and dorsum, providing a potential model for understanding human ECTD-9 and related dermatological conditions.

This study found that in AGA, the risk allele at locus 2q35 alters WNT10A expression through EBF1, suggesting a potential androgen-dependent regulatory mechanism.

This study found that proper levels of retinoic acid, controlled by the enzyme Cyp26b1, are essential for normal hair follicle development and morphogenesis in mice.

This study identifies key transcriptomic features and a necessary dermal niche for eccrine gland development, advancing potential regenerative approaches for these vital skin appendages.

This study found that the HoxC gene cluster plays a critical role in the development of ectodermal organs, including hair and nails, with mammalian-specific enhancers increasing transcription levels during development.
