This study found that RCM combined with dermoscopy can differentiate disease states between alopecia areata, tinea capitis, nevus sebaceous, and linear scleroderma of the scalp by identifying distinct dermal and follicular patterns.

This guideline reviews the diagnosis and treatment of malignant cutaneous angiosarcomas, highlighting the complexity of treatment and the importance of early detection despite non-specific clinical presentations.

In this literature review, researchers found that dermoscopic presentations of pediatric skin conditions often differ between children with skin of color and Caucasian children, with variations influenced by racial backgrounds.

In this article, the authors compile various dermatological conditions that metaphorically reference animal-related visuals, such as "buffalo hump" in HIV-associated lipodystrophy or "leonine facies" in lepromatous leprosy, to enhance learning through mnemonic and visual associations.

The study observed that cell spheres formed from mesenchymal cells of newborn mice skin exhibited upregulation of markers linked to hair follicle regeneration, suggesting a potential hibernation-like state for maintaining viability.

This study developed an in vitro system to analyze human skin progenitor cells' ability to form hair peg-like structures, providing insights for engineering hair follicle organoids.

This study investigated the mechanism responsible for pili torti formation in Björnstad syndrome using a transmission electron microscope, but did not establish a definitive explanation.

This study found that cell spheres formed from mesenchymal cells in newborn mouse skin showed increased expression of genes associated with hair follicle regeneration, though marker distribution varied and requires further investigation.

This study found that a skin-like structure can be generated in vitro by implanting early passage hair follicle bulb cells into collagen/chitosan porous scaffolds.

This study found that the extraction-resistant structures in hair, feathers, and hagfish teeth are due to ε-(γ-glutamyl)lysine cross-linked proteins, emphasizing their role in maintaining the integrity of these materials.

This study identified a new S100 fused-type protein, scaffoldin, in reptiles and birds and suggests that SFTP-positive epithelia serve as scaffolds for the growth of various skin appendages, indicating a common evolutionary origin.

This study introduced a bioengineering platform that creates early-stage hair peg-like structures within tissue-engineered skin substitutes by integrating human keratinocytes and dermal papilla cells with laser-micropatterned collagen scaffolds, providing a foundation for future appendage-inclusive skin regeneration efforts.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

In this study, researchers observed that spiral ganglion neurites created more branched networks near FGF-1-coupled beads compared to control beads, highlighting FGF-1's role in hair cell innervation development.

In this study, researchers discovered a honeycomb-like structure in the skin of spiny mice that facilitates tissue shedding and regeneration, attributed to a uniquely arranged collagen VI and influenced by spiny hair development.

This study found that over-expressing Spry4 and Fgf10 modulates feather stem cells to alter feather morphologies in distinct ways, affecting barb branch formation and tissue structure.

This study found that hair follicle patterning in development may arise from a combination of epidermal prepattern signals and mesenchymal self-organisation, with fibroblast growth factor and bone morphogenetic protein activities playing key roles.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

This study identified two types of hard alpha-keratin filament assemblies in developing human hair follicles, which may help investigate the structural framework of mammalian keratin appendages.

This review discusses historical and recent advances in understanding the embryonic organizer's role in patterning during development, including molecular pathways and future research challenges, but reports no new experimental data.

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

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 examined developing hair cortex with electron microscopy and found that keratin fibrils form between specific regions in hair follicles and aggregate into twisted cables.

This study discovered a novel mechanism by which germ stem cells exit their niche in C. elegans, involving thin membranous protrusions from adjacent somatic gonad cells.
