This study found that the molecular structures of α-keratin and collagen in a 2,100-year-old female cadaver's hair and tendon were preserved, while fibrous molecule aggregations were altered.

This workshop overview concluded that follicular epithelial stem cells are multipotent and located in the bulge region of hair follicles, contributing to hair, epidermis, and sebaceous gland formation.

This article reviews methods for examining the localization and activity of ROP GTPase, cortical microtubule organization, and F-actin dynamics in plant cell models, but reports no new experimental results.

This study demonstrates that hair follicle bulge stem cells can transition into other stem cell compartments, indicating their role in maintaining both hair follicles and sebaceous glands.

In this case study, electron microscopy revealed that harlequin ichthyosis involves giant mitochondria in keratinocytes and abnormal lamellar granule development, which may contribute to pathogenesis through altered lipid metabolism.

This study reported that GFP labeling driven by the K15 promoter enables visualization and selection of stem cells in adult human scalp hair follicles for further analysis and manipulation.

This study found that mouse hair follicle stem cells use symmetric cell division for maintenance and fate determination, and identified Gata6 as a crucial factor for their differentiation.

This study found that newborn mouse skin organoids can robustly grow hair in vivo, while adult organoids require specific interventions to restore their hair-forming ability.

This study found that cultured human dermal papilla cells formed into three-dimensional spheres have an increased ability to induce hair follicles from mouse epidermal cells compared to two-dimensional cultures.

This study reported that the concept of the onychodermis, defined by CD10 expression, is present in the developing nail organ and may play a role in nail plate formation.

The study demonstrated that bulge stem cells from rat vibrissa follicles respond to adult dermal papilla signals, inducing hair bulb formation and regenerating hair structures in vivo.

This study discovered a new region in the hair cortex where intermediate filaments are both aligned with the hair's axis and orientationally ordered, influenced by the cuticle boundary.

This study found that the fuzzy mutation in mice is linked to both structural hair defects and accelerated hair follicle cycling, influencing the regulation of hair cycle phases such as catagen and anagen.

This study found that astrotactin-2 undergoes unique intramembrane proteolysis during maturation, revealing specific transmembrane topologies and substrate sequence requirements for cleavage.

This study described the structure of the hair brush on male Endoclita vietnamensis moths' legs, identifying characteristics such as specialized scales and a pheromone gland, which could facilitate the future development of pheromone-based pest control methods for eucalyptus pests in China.

In this study, the researchers developed a new protocol using human-induced pluripotent stem cells to efficiently create skin hair follicle organoids, which may aid in optimizing hair follicle growth and exploring treatments for alopecia.

This study found that the Arabidopsis thaliana protein Formin 2 localizes to plasmodesmata and is crucial for regulating their permeability by anchoring actin filaments, which affects virus susceptibility.

Two main types of fibroblasts with unique functions and additional subtypes were identified in human skin.

This study found that subcutaneous injections of basic fibroblast growth factor in neonatal mice delayed the development and hair growth cycles of hair follicles compared to controls.

This study found that extracellular factors from a specific developmental stage can promote hair follicle neogenesis in adult skin by facilitating interactions between fibroblasts and keratinocytes.

This study indicates that the Sp6 gene is crucial for the development of skin, teeth, limbs, and lungs in mice, possibly through regulating apoptosis.

This review introduces the morphological and molecular principles of hair follicle development but reports no new experimental results, focusing on recent insights and forming a working hypothesis.

This study found that scaffolds made from human hair proteins supported better cell growth and interactions than control surfaces, indicating potential use in tissue engineering.

In this study, co-grafting human keratinocytes with murine dermal papilla-enriched cells produced hair follicle-like structures, but without regular hair formation, suggesting anomalous folliculogenesis.

This study found that hair follicle stem cells in mice have an unexpected ability to adaptively determine their differentiation pathways, maintaining tissue architecture despite external stimuli.

This study found that fibroblast growth factors exhibit significant expression differences in the skin of rodents and primates, which may be linked to their evolutionary and environmental adaptations.

In this study, Msx2-deficient mice showed progressive hair loss due to shortened anagen phase and prolonged catagen and telogen phases, resulting in cyclic alopecia with structurally abnormal hair shafts.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.
