This study found a high prevalence of clinical signs and functional disorders of androgen excess in premenopausal women, with idiopathic hyperandrogenism and idiopathic hirsutism rates similar to PCOS.

This review discusses melanocyte development, emphasizing the plasticity of melanoblasts and the role of both intrinsic and extracellular signals in their differentiation and migration, with no new clinical results reported.

This study reports that Lef1 plays a crucial role in promoting bulge stem cell differentiation towards hair fate by activating β-catenin and downstream signaling pathways during hair follicle development.

Oral retinoids can cause side effects ranging from mild to severe, including birth defects, and require careful monitoring and contraception.

This review discusses the potential of endogenic and exogenous exosomes in dermatology and cutaneous aesthetics, highlighting their capacity to repair and rejuvenate skin tissue, but reports no new experimental results.

This study validated the VQ-Dermato, the first dermatology-specific quality of life instrument in French, and found it to be reliable, acceptable for routine use, and more responsive than the SF36.

This review discusses potential cell sources and bioengineering strategies for regenerating hair follicles with functional cycling, reporting no new results.

This study found that micrografts containing human hair follicle mesenchymal stem cells significantly increased hair count and density compared to placebo over 58 weeks in patients experiencing hair loss.

This study found that specific SHBG gene variants, rs727428 and rs6259, were associated with PCOS in Mediterranean women, although the associations were relatively weak and do not indicate a causative role.

Blood tests confirmed a baby in the womb had a CMV infection.

This study found that hair follicle stem cells could enhance burn wound healing and improve tissue tensile strength in rats.

This study found that BMP6 and Wnt10b competitively regulate the transition between hair follicle growth phases, offering new insights into hair follicle cycling and potential hair loss treatments.

This study suggests that canonical BMP signaling, particularly involving Smad1 and Smad5, plays a critical role in hair follicle stem cell regulation and hair morphogenesis, with distinct roles from pSmad8.

This study reports that miR-22 promotes cancer progression and metastasis by maintaining Wnt/β-catenin signaling and cancer stem cell function.

This article reviews the cellular dynamics affecting dermal papilla size in androgenetic alopecia and suggests targeting DP size could improve therapies, but it presents no new clinical data.

This study found that the transcription factor Gata6 plays a crucial role in adult mouse hair follicle regeneration by promoting the renewal and preventing DNA damage of rapidly proliferating progenitor cells.

This study provides evidence that Cyclosporine A inhibits catagen development in human hair follicles, suggesting different underlying mechanisms from those observed in rodent studies.

This review discusses the potential of three-dimensional printed mesoporous scaffolds for drug delivery applications, particularly for bone cells and tissues, but reports no new clinical results.

This review discusses the role of immune cells in mammalian hair cycle control and highlights their potential relevance to human hair cycling disorders, reporting no new clinical findings.

This study demonstrated that β-catenin signaling in CD133+ dermal papilla cells enhances postnatal hair growth by accelerating the proliferation and differentiation of keratinocytes in the murine hair cycle.

This study found that applying topical imiquimod during mid and late telogen in mice activates hair follicle stem cells and influences immune cell infiltration, promoting hair cycle entry independently of Wnt signaling.

This review analyzes the impact of different preparation methods for platelet-rich plasma, human follicles stem cells, and adipose-derived stem cells on hair regrowth and wound healing, but reports no new results; the authors emphasize convincing evidence of positive outcomes despite protocol variability.

This study found that despite carrying an activating Hras mutation, hair follicle stem cells integrate into normal skin without causing tumors, unlike similar mutations in the epidermis, suggesting unique tumor-suppressing mechanisms in hair follicles.

In this study, the researchers found that the effectiveness of a 1,550-nm fractional laser in promoting hair growth in mice depends on the specific combination of beam energy and density, with inappropriate settings potentially causing ulcers or hair follicle injury.

This study found that neural stem cell extract enhanced hair growth in mice and cells by stimulating hair follicle niches and activating signaling pathways like TGF-β and BMP.

This study found that low doses of bisphenol A may increase proliferation of the ventral prostate in adult rats by altering the estrogen to androgen ratio and gene expression.

This study found that Twist1 and Tcf4 synergistically regulate the hair follicle induction ability of dermal papilla cells by forming a complex with β-catenin, enhancing their biological properties.

This study found that topical application of mitochondrial electron transport chain inhibitors stimulated hair follicle stem cell activation and hair regrowth in aged mice by promoting lactate production.

In this study, fisetin applied to the dorsal skin of mice activated hair follicle stem cells through exosome secretion from keratinocytes, promoting hair growth.
