In this study, treatment with DHEA induced mild to moderate hyperplasia of sebaceous glands in ovariectomized rats, which was prevented by the antiandrogen Flutamide but not by the antiestrogen EM-800.

This study found that scalp hair follicles had higher expression of cytokeratin 15 and distinct hair layers compared to other body regions, highlighting differences in hair follicle characteristics.

In this study, 0.5% timosaponin BII from Anemarrhena asphodeloides promoted hair growth in C57BL/6 male mice, showing effects comparable to 2% minoxidil.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This article reviews the role of vasoactive intestinal peptide in maintaining immune privilege in hair follicles and does not report new findings; the authors propose it as essential for immune homeostasis in alopecia areata.

This study found that polycaprolactone (PCL) in facial fillers led to more cell proliferation and vascular activity than hyaluronic acid (HA) in Wistar rats, suggesting enhanced tissue regeneration effects with PCL.

This study found that nanovesicles derived from ReNcell VM cells promoted hair growth in mice by activating the Wnt/β-catenin signaling pathway, suggesting they may serve as an alternative to extracellular vesicles for hair growth therapy.

In this study, researchers reported that adenosine stimulated hair shaft elongation in cultured human hair follicles by promoting proliferation and prolonging the anagen phase, suggesting the A2B adenosine receptor in outer root sheath keratinocytes as a promising target for treating hair growth disorders like alopecia.

This article presents a comprehensive guide for classifying human hair follicle cycle stages in vivo using scalp xenografts on immunocompromised mice, offering valuable resources for researchers in the field.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This study found that activation of the TRPV3 ion channel inhibits human hair growth by affecting hair follicles and outer root sheath keratinocytes.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This study found that premature hair loss due to stress does not occur in NK-1 receptor knockout or mast cell deficient mice, suggesting a key role for neurokinin substance P and mast cell interaction in stress-related hair follicle changes.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

This study found that dermal EZH2 plays a crucial role in controlling fibroblast differentiation by regulating Wnt/β-catenin and retinoic acid signaling during skin development.

This study found that Platelet Rich Plasma is effective as a direct pulp capping agent, comparable to Mineral Trioxide Aggregate, but with potentially better cellular dentinogenic responses and homogenous tissue formation in dogs.

This study found that Oriental melon leaf extracts promoted hair growth in a mouse model and cultured human hair follicles, suggesting potential use as a treatment for hair loss.

The study found that dermal EZH2 plays a crucial role in coordinating dermal fibroblast differentiation and epidermal development by modulating Wnt/β-catenin and retinoic acid signaling.

This study found that the Polycomb Repressive Complex 2, particularly its component Ezh2, is crucial in regulating dermal fibroblast differentiation and epidermal keratinocyte proliferation during murine skin development.

This study found that in vivo, a novel microneedle system for valproic acid delivery may improve hair regrowth efficacy by upregulating hair follicle development pathways more effectively than topical application.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

This study in mice demonstrated that stress or nerve growth factor injection increases sensory neuron activity related to skin innervation, suggesting a strong connection between stress perception and neurogenic skin inflammation.

This review discusses the role of the immune niche in hair follicle regeneration and its impact on different forms of alopecia, highlighting research gaps and potential therapeutic strategies.

This review examines how male facial anatomy and behavior contribute to sexual dimorphism in facial aging, pointing to factors that accelerate aging in men but presents no new clinical results.

This study found that gelatin microspheres loaded with platelet-rich plasma enhanced wound healing in rats by improving inflammatory and angiogenic responses compared to untreated wounds or PRP alone.

In this study, topical 5% roxithromycin was effective in restoring hair growth in about half of individuals with androgenetic alopecia without causing adverse effects.

In this study, 150 kHz electromagnetic radiation reduced the number and size of follicular cysts in a rat model of polycystic ovary syndrome without causing significant morphological damage to developing follicles.

This study found that chronic stress may inhibit hair follicle growth and melanogenesis in mice through modulation of the central HPA axis, with C57BL/6 mice appearing most sensitive to these effects.
