This review discusses the developmental plasticity between teeth and taste buds in cichlid fishes and reports no new experimental findings, highlighting potential implications for craniofacial organ patterning and regeneration.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This study observed that during male silkmoth development, trichogen cells in olfactory sensilla undergo significant membrane recycling, contributing to sensillum structure formation in a precisely timed series of stages.

This study found that inhibiting 5α-reductase in molluscs provokes a specific shell morphology, suggesting gastropods might have unique 5α-reductase substrates absent in vertebrates.

This study reports that despite rescuing neurulation and skin barrier defects, Grhl3 gene overexpression in mice leads to hearing impairment, hair loss, and other developmental abnormalities, highlighting low tolerance for Grhl3 dysregulation.

This report describes a rare case of pseudopelade of Brocq in a 20-year-old male, emphasizing its unique presentation with scalp hair loss and mild itching.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.

This study found that changes in the expression of the Agouti gene contribute to the pale pigmentation in beach mice, with implications for melanocyte development and localization.

In this case report, researchers observed that a malnourished male patient developed pseudoglucagonoma syndrome, characterized by necrolytic migratory erythema and diffuse hair loss, following Frey's surgery, which rapidly improved with enhanced nutrition.

This paper reviews the evolution of skin appendages and keratin-associated proteins among amniotes, proposing a model for their genetic divergence without new experimental results.

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.

This case report identifies a 32-year-old woman with undiagnosed PHPT-1a who exhibited complete pseudo-anodontia and persistent patchy alopecia areata, suggesting these may be new nonclassical features of a GNAS pathogenic variant.

This review discusses spatial and temporal patterns in animals, focusing on skin appendage organs, but provides no new research findings.

This study found that the proteins Par3, mInsc, and Gαi3 cooperate to regulate LGN polarization and promote perpendicular cell divisions during murine epidermal morphogenesis.

In this study, researchers used a hypospadiac rat model to demonstrate abnormal genital development, similar to human penoscrotal hypospadias, highlighting the model's value for studying penile growth and differentiation.

This study found that Atlantic croaker nuclear androgen receptors AR1 and AR2 have different binding affinities for androgens, suggesting that they may mediate distinct physiological actions in teleosts.

This study suggests that exogenous retinoic acid can alter the morphogenesis pathway of developing skin appendages when applied during the placodal stage, leading to changes like feather formation in atypical regions of chick embryos.

This study found that cortexolone 17α-propionate (clascoterone) effectively inhibited androgen receptor-regulated transcription and IL-6 synthesis in scalp cells, potentially making it a promising candidate for topical treatment of androgenetic alopecia.

This study found that zebrafish and sticklebacks, despite differences in their tooth regeneration structures, share a similar genetic program during tooth regeneration, suggesting a conserved "successional dental epithelium" in vertebrates.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

This study found that Sonic hedgehog pathway expression strongly correlates with tail regeneration in house geckos, peaking early and decreasing afterward.

This case report describes a Thai male with TRPS1 who exhibited unique and unreported features such as hypoplastic mandibular condyles, double mental foramina, and distinctive hair abnormalities.

This study described a Scottish family with hidrotic ectodermal dysplasia featuring variable symptoms such as hypo/oligodontia, thin hair, and heat tolerance, and concluded they exhibited overlapping traits with Clouston syndrome.

This study concluded that pseudopelade is an autosomal dominant condition, distinct from other forms of alopecia, characterized by atrophic hair follicle loss and notable familial association.

In this case report, a rare instance of Graham–Little–Piccardi–Lassueur syndrome coexisting with linear lichen planus was identified in a 35-year-old male, highlighting the condition's rarity in males, with dermoscopy aiding diagnosis through distinctive scalp and trunk lesion features.

This review discusses the regenerative processes of lizard tails, particularly focusing on the diversity in blastema development across different species, and reports no new findings.

This study suggests that pseudopelade may be an autonomous disease based on its distinctive clinical and histopathological features not present in other scarring alopecias.

This study described two cases of trichoblastomas in the tactile hair skin of aged house musk shrews, highlighting that their histological structure differs from that in humans and other animals.

Capitate trichomes have more endoplasmic reticulum and vacuoles, while peltate trichomes have more plastids and larger subcuticular spaces.
