In this study, LHX2 and SOX9 were found to mark distinct epithelial progenitor cell populations within human hair follicles, suggesting roles in maintaining the hair follicle epithelium.

In this study, researchers found that overexpression of IGF-1 in transgenic mice stimulated increased vibrissa growth during the first neonatal hair cycle compared to their nontransgenic littermates.

Propranolol can cause reversible hair loss.

This study found a significant shift to the telogen phase in the hair growth of children with classical marasmus compared to normal children, suggesting a connection to the chronicity of the condition.

This study found that human iPSC-derived melanocytes from vitiligo patients successfully integrated into mouse hair follicles and epidermis, demonstrating potential for personalized therapy for depigmentation.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This article discusses the presentation of chemotherapy-induced anagen effluvium as either diffuse or patterned hair loss and reports no new clinical findings.

This study identified a large deletion in the desmoglein 4 gene as the genetic basis of the Iffa Credo "hairless" rat's skin phenotype, linking it to lanceolate hair mutations.

This study found that white wax and its extract may promote hair growth in a mouse model of androgenetic alopecia by inhibiting 5α-reductase activity and increasing cell proliferation, with efficacy surpassing finasteride.

This study found that taurine uptake by isolated human hair follicles promoted hair survival and protected against TGF-β1-induced damage in an in vitro setting.

This study reported that heterozygosity for FHIT affects mice's susceptibility to spontaneous alopecia areata and to certain preneoplastic lesions induced by benzo[a]pyrene, but does not change how they respond to budesonide and N-acetyl-L-cysteine.

This study found that ornithine decarboxylase expression is linked to cell proliferation and differentiation in hair follicle development and growth.

This review discusses the cutaneous application of bimatoprost ophthalmic solution 0.03% for enhancing upper eyelash growth and suggests it is both safe and effective; no new clinical results are reported.

This study found that supplementing pregnant and lactating mice with high dietary copper improved survival and physical traits in mice carrying the crinkled mutation, suggesting copper's role in modulating gene expression.

This study observed that cathepsin L and transglutaminase 3 colocalize in the human hair bulb and nail matrix, suggesting their involvement in terminal differentiation within these epidermal appendages.

This study found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

This study found that human placental extract promoted hair growth and influenced cellular pathways in vitro and rat models, suggesting potential for future hair loss treatments.

This study found that in male androgenic alopecia, the androgen receptor coactivator ARA70/ELE1 exhibits differential expression patterns, suggesting its involvement in the condition.

This study identified a marked reduction in melanin in the hair of Yorkshire Terriers with Colour Dilution Alopecia and proposed a new pathogenetic mechanism based on these observations.

This review discusses the migration and colonization of melanocytes from the neural crest in mammals and reports no new experimental results.

This study found that unsaturated fatty acids are more abundant in the cortex of human hair than on its surface, and steryl glycoside-like lipids may help bind the cuticle to the cortex.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This study found that KF19418 stimulated hair follicle growth in vitro and accelerated hair regrowth in a mouse alopecia model, with effects comparable to minoxidil.

In this study, various types of minor hair follicle damage were observed during follicular unit extraction, with paring and hair bulb injury being more apparent under microscopic examination.

In this study, human hair follicles showed varying expression of cholesterol transport proteins during the hair cycle, suggesting a potential role of cholesterol in hair growth and cycling.

This study characterized a novel form of mural folliculitis in dogs, resembling human pseudopelade, marked by persistent alopecia, lymphocyte infiltration, and severe follicular atrophy without effective treatment response.

In this study, human hair follicles were maintained in a serum-free medium for up to 12 days, revealing detailed histological and ultrastructural changes that suggest possible catagen-like involution mechanisms.

Junctional proteins stabilize the inner root sheath and connect the companion layer in human hair.

This study observed that primary hair follicles in Liaoning Cashmere goats had broader hair bulb widths compared to secondary follicles, with the difference diminishing during the anagen phase of hair follicle development.

In this study, growing human hair follicles in a defined glycosaminoglycan hydrogel ex vivo promoted cell survival, proliferation, and activation of hair growth-related signaling pathways, suggesting GAG-based hydrogels could modulate the hair follicle growth cycle.
