This study reports that transgene insertion in homozygous transgenic mice causes irreversible hair loss and impaired immune function, linked to interruption of the hairless locus on Chromosome 14.

This study identified a compound heterozygous mutation in a hairless rhesus macaque, which was associated with skin abnormalities similar to those in hairless mice and humans with APL.

In this case report, researchers described a unique skin lesion in a 55-year-old woman, identifying it as folliculosebaceous cystic hamartoma with an unusual combination of spindle cell lipomatous and neural components, which had not been previously documented in such cases.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

In this study, dermoscopy was suggested as a potentially useful tool for improving the clinical recognition of pilomatricoma.

This study observed that in primary extramammary Paget disease, carcinoma commonly spreads to significant depths along hair follicles and eccrine ducts, with a maximal depth of 3.6 mm.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This publication provides a standardized nomenclature for classifying microscopic lesions in laboratory rat and mouse skin, aiming to harmonize international toxicological research.

This review discusses transdermal drug delivery using hydrogel-forming microneedles and highlights their potential for disease treatment, but notes challenges in their clinical application.

This study demonstrates the potential of using bioengineered follicles from adult tissue-derived stem cells for fully functional hair regeneration, illustrating possible applications in organ replacement therapy.

This review discusses evidence-based guidance for managing primary cicatricial alopecias but reports no new clinical results, highlighting significant gaps in knowledge and the need for more quality trials.

This study found that intradermal QR678 Neo® therapy improved scalp condition in men and women with seborrheic dermatitis unresponsive to standard treatments, reducing flaking and inflammation after eight sessions, with high patient satisfaction reported.

This review outlines the evolution of hair follicle engineering and its foundational discoveries, but reports no new experimental results.

This study found that PBMCsec has anti-fibrotic effects on mouse and human skin scars by regulating pro-fibrotic gene expression and inhibiting myofibroblast differentiation and elastic fiber breakdown.

This study found that administering an adenovirus vector to increase Sonic hedgehog gene expression in mouse skin accelerated the transition of hair follicles into the growth phase, promoting hair growth.

This report describes cases of trichoblastoma and trichoepithelioma in mixed-breed dogs, highlighting their distinct microscopic characteristics without suggesting broader clinical implications.

This review explores the potential of self-amplifying RNA technology for protein replacement therapy in various health disorders but reports no new experimental results, indicating challenges remain for clinical approval.

This study reports the first case of atrichia with papular lesions in a Taiwanese family without a detectable mutation in the HR gene.

This review discusses the classification and diagnosis of primary cicatricial alopecias and reports no new clinical results; it highlights the need for effective treatments owing to limited evidence of current therapies' efficacy.

This study found that cutaneous cysts most frequently appeared as epidermal cysts, with unusual locations posing diagnostic challenges that required histopathological analysis for definitive diagnosis.

This article explores the potential mechanisms by which polydeoxyribonucleotide (PDRN) could improve skin quality, slow aging, and enhance skin regeneration, but reports no new clinical findings.

This review discusses the broadening scope of botulinum toxin applications beyond traditional uses, highlighting its effects on non-neuronal cells and potential in treating various dermatological conditions, without reporting new clinical findings.

This review discusses the role of Cytochrome P-450 in dermatology and reports no new clinical results.

This study observed that benign skin tumors were more common than malignant ones, with squamous cell carcinoma being the most frequent type among malignant tumors.

This study found that Polyomavirus A2 infection in mice led to the development of pilomatricomas in hair follicles, with the virus replicating initially in the skin and later infecting matrix cells.

This chapter classifies various benign skin tumors and discusses their characteristics, treatment indications, and potential for recurrence, but reports no new clinical findings.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

This article discusses the association between chronic diffuse telogen hair loss in women and iron deficiency, supporting the view that iron's role is unclear and often overstated, but reports no new clinical results.

This study discusses incidental findings of syringomas and syringomatous proliferations in areas of scalp alopecia, suggesting they may be secondary to reactive changes from subclinical alopecia.
