In this study, researchers observed that the sebaceous gland niche in mice allows for Wnt-induced hair follicle differentiation, unlike the non-permissive bulge.

This letter discusses tissue expansion for correcting alopecia in a child with hypohidrotic ectodermal dysplasia, but provides no new experimental results.

This study reports that corneal transient amplifying cells can be reprogrammed into epidermal cells capable of forming hair follicles in response to embryonic dermis signals.

Hair shaft changes may be linked to CCCA, but their role is unclear.

This study suggests that reptilian claws grow differently from mammalian claws, with continuous epidermal growth rather than a proximal matrix zone for cell proliferation.

This case report describes a hybrid cyst in a Sprague-Dawley rat, showing both infundibular and matrical differentiation similar to different parts of normal hair follicles.

In this study, the researchers identified LHX2 as a specific marker for hair follicle placodes, differentiating them from eccrine sweat gland placodes through double immunofluorescence staining.

This study in a nine-year-old boy from Lebanon identified a gene mutation (c.1066dup p.(Arg356Profs*16)) associated with a rare inborn error of immunity, characterized by craniosynostosis, jaundice, and several other symptoms, expanding the known genotypic and phenotypic spectrum of this condition.

In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

This study found that nestin-expressing unipotent progenitor cells capable of differentiating into outer root sheath keratinocytes are present during hair follicle development and in adult hair follicles.

This study details the presence of two types of cysts in rhino mouse skin, with utricles derived from hair canals and deeper cysts from hair root sheath epithelium.

This study identified a novel skin site called the follicular epidermis that is prone to cancer, with unique Axin2+ stem cells regulating its homeostasis. The findings suggest current therapeutic approaches may need reconsideration due to new insights into obstruction mechanisms at this site.

This article presents a case of an 8-year-old boy with Recklinghausen's disease showing features such as café-au-lait spots, alopecia, and developmental anomalies, but reports no new findings beyond observation.

This case study describes a rare cutaneous follicular hybrid cyst intimately associated with syringocystadenoma papilliferum, proposing a potential relationship with the infrainfundibulum based on keratin expression.

This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

This case study presents a 9-month-old male infant with symptoms suggesting a likely diagnosis of Hay–Wells syndrome, including severe scalp crusting, nail abnormalities, and partial syndactyly.

This case report observed a 5.5-year-old girl with Ectodermal Dysplasia-Syndactyly Syndrome 1, who experienced improved hair density and thickness with topical minoxidil and tretinoin, suggesting a potential adjunctive role for topical retinoids, though confirmation in larger studies is needed.

This case report documents the first known occurrence of alopecia areata in a patient with ectodermal dysplasia linked to a WNT10A mutation, suggesting potential shared genetic factors in hair loss pathways.

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 observed that retinoic acid biosynthesis and signaling in hair follicles have a spatial and temporal regulation linked to distinct stages of the hair cycle in mice.

In this case report, a five-year-old girl with a bald patch was diagnosed with congenital triangular alopecia, a localized non-scarring condition that typically remains unchanged and lacks effective treatment.

In this study, deleting the Igf1 receptor in specific skin cells of mice affected hair follicle cycling but not overall skin health, suggesting Igf1r's role in hair cycle regulation through Bmp-4 activation.

This case study discusses a 36-year-old female diagnosed with a facial variant of eruptive vellus hair cyst, confirmed by skin biopsy, and highlights the importance of considering this condition in the differential diagnosis of asymptomatic facial papules.

This study presents evidence that hair matrix progenitors and the enzyme Stearoyl CoA Desaturase 1 may play a role in maintaining the dermal papilla niche via autocrine Wnt and paracrine Hedgehog signaling in mice.

This study reports differential gene expression in the leading edge and inner surface epithelial cells of murine eyelids, suggesting that distinct signaling pathways are active during embryonic eyelid closure.

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

This case report highlights the importance of histopathological examination in accurately diagnosing eruptive vellus hair cyst due to its rarity and resemblance to other conditions.

This study characterized a new human keratin, hK6irs1, specifically found in the inner root sheath of hair follicles, which suggests its role in the structural integrity and guidance of growing hair shafts.

The authors suggest that tooth, dermal scale, epidermal scale, feather, and hair evolved in parallel from a shared placode/dermal cell unit in an early vertebrate gnathostome with odontodes, around 420 million years ago.
