In this study, researchers developed a multilayered gel bead culture model using a microgel-spotting device, successfully mimicking the early development of skin appendages and supporting in vitro hair follicle regeneration with structures resembling native hair follicles.

This study suggests that hair follicle stem cells from transgenic mice can improve nerve regeneration and function, highlighting their potential as an autologous source for regenerative medicine.

This case report describes a black male newborn who developed bullae that healed with hypopigmentation, linked to collagenolysis and RER vacuoles potentially containing proteolytic enzymes.

This review discusses various approaches to treating alopecia, including drug therapy and hair transplantation, but reports no new research findings; the authors highlight the need for novel techniques like cell culturing.

Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.

This review explores androgen metabolism in the skin, highlighting enzyme localization and potential implications for treating androgen-dependent skin conditions, but it reports no new clinical results.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This study found that a peripilar white gray halo around hair emergence is a highly specific and sensitive dermatoscopic feature for diagnosing central centrifugal cicatricial alopecia in African American patients with mild central thinning.

This study found that TSC2-null fibroblast cells from TSC skin hamartomas can induce hair follicle formation and hamartomatous changes in keratinocytes, with active mTOR signaling observable in a mouse xenograft model.

This study found that α-tocopheryl acetate is well absorbed through healthy skin, with absorption occurring through specific pathways and showing high affinity for small blood vessels.

This study describes a newly observed "inflammatory vellus involvement" pattern in early frontal fibrosing alopecia, which may lead to misdiagnosis due to the absence of typical histological features.

This study found that rice bran ash extract enhanced melanin biosynthesis-related protein expression in a 3D hair follicle-like tissue model and hair follicle organ culture, suggesting potential for future research in melanogenesis.

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 found that Wnt3a increased beta-catenin signaling and upregulated specific genes in cultured human dermal papilla cells, enhancing their response to PGE2 and potentially aiding hair growth.

This review discusses the roles of epithelial-mesenchymal interactions and dermal papilla in hair follicle growth and cycling, but it reports no new clinical results.

The review concludes that accurate diagnosis of different types of hair loss requires proper biopsy techniques and understanding the hair growth cycle and underlying causes.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

This study demonstrated that hair follicle-derived cells can induce hair follicle formation in an in vitro skin organ culture system using human retroauricular skin specimens.

This study found that in androgenetic alopecia, reduced stem cell factor production by dermal papilla cells may lead to decreased pigmentation in hair follicles.

This study found that in mouse skin, the activation of stem/progenitor cells is synchronized across different niches during growth, with the glutamate transporter SLC1A3 playing a crucial role in this process.

In this study, a synthetic antagonist of the p75 neurotrophin receptor was found to significantly inhibit hair follicle regression in murine skin cultures, suggesting a potential role in treating hair disorders characterized by premature catagen entry.

This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.

This letter to the editor compares the efficacy and safety of bimatoprost 0.03% with minoxidil 3% for eyebrow enhancement but does not report any study results.

This review summarizes recent progress in human hair follicle bulge cell research, particularly the characterization and isolation of these stem cells, but reports no new experimental results.

This study found that diffuse alopecia in HIV-1-infected patients is characterized by higher rates of follicular stem cell apoptosis compared to controls, suggesting a hair cycle disturbance associated with the infection.

This study observed that human anagen hair follicles can grow in vitro when maintained serum-free, with possible implications for understanding hair follicle growth mechanisms.

This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This preliminary study observed that melanoblasts are preserved in the white hair follicles of segmental vitiligo lesions.

This review summarizes major growth factors that promote hair follicle growth, but it reports no new experimental findings.

This study identified a high-risk allele in the PLCD1 gene associated with hereditary trichilemmal cyst formation, proposing a monoallelic two-hit mechanism as the underlying genetic pathogenesis.
