This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

In this case report, a 6-year-old boy with Netherton syndrome was diagnosed using trichoscopy, which revealed characteristic hair shaft abnormalities such as bamboo, golf tee, and matchstick hairs.

This study found that transplanted ES cell-derived epidermal stem cells promoted the formation of epidermis, sweat gland-like, sebaceous gland-like, and hair follicle-like structures in mouse skin defects.

This study found that novel compound heterozygous mutations in the desmoplakin gene lead to hair shaft abnormalities and can result in lethal cardiomyopathy.

This review discusses the role of genetic mutations and environmental endocrine disruptors in insufficient androgen action, which can result in conditions like hypospadias, cryptorchidism, and micropenis, during male fetal development.

This mini-review discusses human hair follicle development and summarizes genetic disorders linked to abnormalities in hair follicle morphogenesis, structure, or regeneration, but reports no new experimental results.

This paper describes a case of epidermolysis bullosa simplex with muscular dystrophy associated with a novel PLEC mutation and diffuse alopecia, highlighting a potential genetic link that remains uncertain.

This review discusses dermatologic signs in childhood endocrine disorders and highlights their importance in early diagnosis and treatment, but it reports no new clinical findings.

This review describes how recent discoveries in genetic defects and alternative pathways in androgen biosynthesis are reshaping our understanding of male sexual differentiation, but it presents no new clinical findings.

Skin organoids can regenerate hair by forming specific cell units with certain signals.

This case study of a 50-year-old woman with myotonic dystrophy and multiple basal cell carcinomas suggests there could be a genetic predisposition for certain cutaneous tumors in such patients.

This study found that inducing Atoh1 expression in transgenic mice is sufficient to generate new Merkel cells in the epidermis, with variations by skin location, developmental age, and hair cycle stage.

Hoxc13 is important for hair and tongue development by controlling hair keratin genes.

This study suggests that egfl6 expression in the pharyngeal pouches is not essential for craniofacial development in zebrafish.

This report details the clinical presentation of an 18-year-old female with Kallmann syndrome, noting her ocular issues and differences in sexual development. The researchers treated her eye conditions cosmetically with superficial keratectomy and amniotic membrane graft, followed by corneal tattooing and strabismus correction.

This study found that desmosomal adhesion plays a crucial role in epithelial morphogenesis and cell positioning, equivalent in importance to that of adherens junctions.

In this case report, a 12-year-old girl was diagnosed with alopecia as part of the rare ALX4-related frontonasal dysplasia sequence, highlighting the condition's uniqueness in pediatric dermatology.

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 identified novel compound heterozygous mutations in the DSG4 gene in a Japanese patient with congenital hypotrichosis, suggesting overlap between localized autosomal recessive hypotrichosis and monilethrix.

This review reports two new cases of porokeratotic eccrine and hair follicle nevus and analyzes all known cases in the Spanish and English literature, suggesting a link to a GJB2 gene mutation.

This paper reviews different types of hair shaft dysplasias and does not report any new clinical findings.

In this study, mice engineered to express human EGFR showed tissue-specific growth defects and neurodegeneration rescue, but developed severe heart issues and accelerated bone cell differentiation.

In this study, mutations in the CDH3 gene were identified as the cause of hypotrichosis with juvenile macular dystrophy, and the researchers observed substantial phenotypic variability among affected individuals.

This study suggests that congenital atrichia with papular lesions may be more common than previously thought and proposes diagnostic criteria including the observation of hypopigmented whitish streaks on the scalp.

This case report describes a male child with alopecia areata and renal dysgenesis, highlighting a possible coincidental association that may require future genetic investigation.

This case report describes a 10-day-old female with aplasia cutis congenita, presenting with two spontaneously healing ulcers on her buttock and no associated abnormalities.

This study describes three adult dogs with sebaceous gland dysplasia, reporting that two showed moderate to marked improvement in symptoms with treatment, though ongoing management is required as the condition cannot be cured.

This study found that a nonsense mutation in the Cst6 gene of mice leads to severe skin and hair abnormalities, suggesting that cystatin M/E is crucial for epidermal function and viability.

This study found that transgenic mice expressing a mutant E1a oncoprotein in their skin had disturbed hair follicle maturation but did not show increased tumor development or proliferation.
