The researchers reported that applying proteolytic enzymes to mice skin negatively affected hair follicles, leading to degeneration and potential impairment of stem cells from the bulge area.

This study found that topical treatment with Maneb led to delayed epithelial cell degeneration in hair follicles of rats due to apoptosis.

This article discusses the structures surrounding hair follicles and introduces aspects like follicle groups and the dermal sheath, but it reports no new research findings.

In this study, AgK114 was found to be transiently induced in hamster epidermal keratinocytes following skin damage, suggesting its role in the recovery process after injury.

This study found that transplanting trichogenous dermal cells significantly enhanced the restoration of in vivo-damaged hair follicles in a nude rat model, with a combination of dermal papilla and sheath cells proving more effective than either cell type alone.

This study identified dual epithelial and mesenchymal traits in dermal sheath cells during wound repair, suggesting they could be targeted to enhance healing.

In this study, the researchers observed that inducing and then withdrawing β-catenin expression in a bigenic mouse model caused reversible changes in skin morphology, indicating dependence on β-catenin signaling.

This review explores the roles of dermal sheath cells in wound healing, highlighting their multifunctional contributions to inflammation, proliferation, and extracellular matrix remodeling, and proposes new insights into tissue regeneration and repair, especially in differentiating between hairy and non-hairy skin sites.

This review discusses the role of Sox2 in skin development, hair follicle regeneration, cancer, and wound healing, and reports no new experimental results.

This review discusses insights into the role of lipase H in controlling hair form and texture, emphasizing genetic mutations linked to autosomal recessive woolly hair/hypotrichosis, and reports no new experimental results.

This study found that trichoscopic examination can effectively differentiate between alopecia areata and trichotillomania, as specific features such as black dots and exclamation marks favor alopecia areata while hair breaking at various lengths and several unique patterns are exclusive to trichotillomania.

This study observed that CXCL12 is highly co-expressed with androgen receptors in human hair follicle cells, and its inhibition via antibodies increased hair length, suggesting a potential treatment strategy for androgenic alopecia.

This study analyzed inner root sheath-specific genes in Tan sheep during various growth stages, finding peak expression at birth. The pattern of genes KRT71, KRT72, and TCHH is consistent with wool crimp, potentially influencing wool morphology.

This article reports an unprecedented case of trichofolliculoma in the gluteal area, previously unreported in English literature.

This study revisits and reproduces Felix Pinkus' concept of the vitreous membrane in hair follicles, suggesting these structures may play a role in differentiation or nutrition due to their location in metabolically dynamic regions.

In this study, researchers found that stabilizing the protein HIF1A in hair follicles promotes glycolysis over oxidative phosphorylation, potentially reducing oxidative stress and supporting hair growth.

This study suggests that human hair follicles may operate their own Cori cycle, synthesizing glycogen from lactate under conditions of lactic acidosis.

This study found that stabilizing HIF1A in hair follicle cells promoted a shift to glycolysis, potentially reducing oxidative stress and promoting hair growth, particularly in balding dermal papilla cells.

This review discusses the role of dermal sheath cells in hair follicle regeneration, suggesting they show potential for treating pattern hair loss, but emphasizes the need for further human studies.

Hair growth is cyclic and influenced mainly by local factors.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study reports the cloning and expression details of two new human type II keratins, K6irs3 and K6irs4, in the hair follicle's inner root sheath, suggesting a distinct functional role related to hair structure.

This study found that C8/144B antibody exclusively binds to the hair follicle bulge and not the epidermal stratum basale, with cytokeratin 19 serving as a key marker of certain basal keratinocytes that decrease with age.

This study found that horizontal sections of scalp biopsies in patients with Central Centrifugal Cicatricial Alopecia often reveal follicular miniaturization, inflammation, and scarring, which can guide personalized treatment.

In this study, different donor and recipient site preparation techniques for melanocyte-keratinocyte suspension were associated with similar repigmentation outcomes in stable vitiligo, but efficacy varied by body site.

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 demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study identified a genetic variant in the CTS6 gene associated with a hypotrichosis syndrome, emphasizing the significant role of cystatin M/E in hair and skin health.

This study demonstrated the potential of epithelial cell scaffolds fabricated with various materials for effective hair regeneration, highlighting their promising application in tissue engineering for alopecia treatment.

This article discusses the applications and contraindications of skin grafts in wound treatment and reports no new research findings.
