This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

This study found that multipotent neural crest stem cells from hair follicles require a full set of reprogramming factors for induced pluripotent stem cell induction, similar to fibroblasts.

Skin aging reflects overall body aging and can indicate internal health conditions.

This study found that osteopontin expression was significantly higher in alopecia areata lesions compared to healthy controls, suggesting it may play a role in the disease's pathogenesis.

This genetic study identified a potential interval for the Marie Unna hypotrichosis gene but found no mutations in the nearby hr gene, suggesting its involvement remains unconfirmed.

This study found that obesity in women may impair endometrial stromal function and contribute to reproductive complications, possibly due to metabolic influences rather than immune cell differences.

This study reveals that CSPG4-positive basal cell keratinocytes show distinct global gene expression from CSPG4-negative cells, despite similar colony-forming efficiency.

This study found that novel RNA aptamers specifically inhibited FGF5-induced cell proliferation, suggesting their potential as candidates for treating FGF5-related diseases or hair disorders.

This study found that finasteride treatment of male rats led to changes in their male offspring's testicular gene expression, potentially affecting sperm function in response to odorant-like signals.

This research concluded that the novel hydrogel PlacMA, derived from human placenta and curable by visible light, shows promise for cell culture and tissue engineering applications due to its tunable properties.

This paper discusses the role of steroid sulfatase in hormone-dependent tumors and highlights the development of potent inhibitors, noting the commencement of a phase I trial for one inhibitor in postmenopausal breast cancer patients.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

In this study, researchers found that wound healing in mouse skin recruits diverse fibroblasts, including myeloid-derived cells, which contribute to regenerating adipocytes.

This study identifies mutations in the SRD5A3 gene as a cause of a new type of congenital disorder of glycosylation, impacting mental, ophthalmologic, and cerebellar functions.

This review discusses the role of TGF-β signaling in stem cell recruitment and tissue regeneration, indicating that abnormalities in TGF-β activation contribute to various major diseases and suggesting avenues for therapeutic intervention.

This review discusses the biochemical properties and clinical significance of 5 alpha-reductase isozymes and reports no new clinical results.

This study identified 19 specific genes involved in root hair growth and morphogenesis in Arabidopsis, using a combination of computational and experimental methods.

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

This study reports that overexpression of activin in transgenic mice enhances granulation tissue formation during wound healing, highlighting a novel role for activin in cutaneous repair processes.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This review discusses the role of 5α-reductase enzymes in androgen action and related disorders, noting that their specific inhibitory drugs show promise for conditions like benign prostatic hypertrophy; it reports no new clinical results.

In this study, researchers identified a specific T cell receptor associated with carbamazepine-induced severe cutaneous adverse reactions, demonstrating its potential for therapeutic development in patients with the HLA-B*15:02 genotype.

This study suggests that the GPX-PDE1 and GPX-PDE2 genes in white lupin enhance root hair development and contribute to Pi limitation acclimation by facilitating glycerophosphodiester degradation.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.

Certain fungi and bacteria help orchid seeds germinate and plants grow better.

This study identified that the enzyme CYP2B12 is skin-specific and likely plays a role in the metabolism of arachidonic acid, a key component in lipid signaling within sebaceous glands.

This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.
