This study found that pubic skin fibroblasts respond to androgens, increasing 5α-reductase activity via an androgen receptor-mediated mechanism, suggesting its potential as a marker of androgen action in vitro.

This study found that the Ovol2-Zeb1 regulatory circuit is crucial for controlling directional migration and proliferation in epithelial cells, facilitating skin regeneration and repair in mice.

This study found that 15-dPGJ2 promotes apoptosis in human follicular keratinocytes, suggesting its potential role in developing hair loss prevention treatments through DP2 antagonism.

This abstract reports no new clinical results and discusses the importance of follicular unit storage for the success of hair transplantation surgery.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study found that the enzyme A20 helps regulate EDAR-induced NF-κB signaling in mice, preventing ectodermal abnormalities like disheveled hair and assuring proper skin and appendage development.

This study reports that overexpressing the BMP antagonist noggin in mice inhibits eyelid opening by reducing apoptosis and delaying cell differentiation in the eyelid epithelium.

In this study, enteroendocrine cells were shown to coordinate intestinal stem cell migration towards a wound in Drosophila by releasing a ligand that activates non-canonical Wnt signaling, aiding efficient tissue repair.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

This study found that despite the persistence of aberrant double-negative T-cells, functional immune-competence was maintained after thymic transplantation in a patient with a rare FOXN1 mutation.

This study found that while bimatoprost was safe for 16 weeks, it was not effective for eyelash growth in patients with significant loss due to alopecia areata, though some with less loss experienced growth.

This study reported that prenatal exposure to dihydrotestosterone altered long-term androgen metabolism in juvenile male rats, suggesting different regulatory mechanisms for 5a-reductase in hypothalamic versus pituitary tissues.

This study found that UV-B exposure significantly increased the expression of inflammatory cytokines IL-1β and IL-8 in cultured sebocytes.

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.

This study demonstrates that human hair follicle stem cells can be cultured and expanded without major changes to their phenotypes, which suggests potential for use in regenerative medicine.

This study on feather pattern formation in chicken skin found that inhibiting gap junctional intercellular communication can lead to the emergence of new feather buds in specific spatial patterns, suggesting that GJIC may facilitate Turing-type periodic patterning by propagating inhibitory signals over long distances.

Nanoparticles can be used to deliver drugs to hair follicles, potentially improving treatments for conditions like acne and alopecia, and could also be used for vaccine delivery and gene therapy.

In this study, collagen I decellularized scaffolds enhanced the growth and melanotic properties of hair follicle melanocytes, suggesting their potential as effective carriers for transplantation in vitiligo treatment.

Scalp cooling prevented hair loss in half of the patients, despite significant side effects.

In this study, tofacitinib treatment led to significant hair regrowth in 60% of patients with moderate-to-severe alopecia areata, suggesting potential for JAK inhibitors in treating this condition.

In this study, blocking autophagy with 3-methyladenine significantly improved the survival of inner ear hair cells in a gentamicin-induced ototoxic mouse model.

This review evaluates laboratory models used in androgenetic alopecia research but reports no new findings, emphasizing the potential of human-derived 3-D models for future studies.

This study found that water extract of olive leaf may enhance markers linked to epidermal and dermal stem cell activity and potentially improve skin aging, especially in individuals who do not exercise regularly.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.

This study found that canine hair follicle stem cells in vitro expressed markers associated with multipotency, suggesting their potential role in the hair cycle.

This study suggests that miR-486 may protect against alopecia areata by maintaining hair follicle immune privilege and modulating expression of immune-related genes.

In a laboratory setting, this study found that Biotrinine® dry extract activated hair follicle growth pathways and increased certain growth factor secretions in human dermal papilla cells, suggesting potential benefits for treating chronic hair loss.

This study observed that Ginseng and Albizia extracts, when used together, protected human dermal papilla cells from oxidative stress-induced senescence, and inhibited genes that suppress hair growth, indicating their potential in preventing age-related hair density reduction.

This study suggests that low-dose blue light (453nm) may positively affect hair growth by interacting with the receptors CRY1 and OPN3 in hair follicle cells.

This study suggests that mitochondrial dysfunction might contribute to the pathogenesis of Lichen planopilaris by triggering a metabolic shift that leads to chronic inflammation and hair follicle damage.
