This study found that the mammalian hairless gene encodes a corepressor protein that interacts with thyroid hormone receptors, providing insights into hair loss syndromes in humans and mice.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

In this study, hyperandrogenemia in young women with polycystic ovary syndrome was linked to higher blood pressure, independent of factors like age, insulin resistance, obesity, or dyslipidemia.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

This study found that mechanical skin stretching can stimulate hair stem cell proliferation and hair regeneration by activating a complex pathway involving WNT, BMP-2, and M2 macrophages.

This study found that the HairMax LaserComb® significantly increased hair density and was safe and well tolerated for treating androgenetic alopecia in men compared to a sham device.

This study observed that applying JAK-STAT pathway inhibitors to mouse and human skin led to rapid hair growth by inducing the anagen phase of hair follicles.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This article reviews the biological and physical principles of laser hair removal and reports that current laser systems do not consistently achieve permanent hair follicle destruction across treated areas.

This study reported that transgenic mice with targeted TNF alpha expression in keratinocytes showed impaired weight gain, retarded hair growth, and skin changes, leading to cachexia and necrosis.

This study found that aging in the epidermis disrupts cytokine balance and stem cell function, which may contribute to broader tumor-suppressive mechanisms.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

This review discusses the role of the circadian clock in skin functions such as cell proliferation and UV protection and reports no new results; the authors note its potential in studying immune regulation and seasonal behaviors.

This review discusses the extraction, purification, modification, and biological activity of polysaccharides from Traditional Chinese Medicine and reports no new research findings.

This study found that in mice, dermal adipocytes initiate inflammation and aid repair after skin injury by releasing lipids, suggesting a role in managing inflammatory diseases and impaired wound healing.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

This review provides an overview of recent tissue engineering and regenerative medicine developments in Asia, highlighting significant advances, representative research achievements, and discussing future directions, without presenting new research results.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This review discusses various adverse drug reactions affecting the skin, hair, and nails, emphasizing the importance of recognizing and reporting these reactions but reports no new clinical findings.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

Hair loss linked to higher heart disease risk in both men and women.

This study found that long-term minoxidil treatment, despite improving hemodynamics and left ventricular function, was associated with more frequent clinical events and a poorer clinical course in patients with chronic left ventricular failure.

This study found that PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

In this study, sequences upstream of the TGM3 gene were found to regulate epithelial-specific gene expression in keratinocytes, suggesting potential applications in gene therapy.

This study found that maternal PPARγ is essential for preventing the production of inflammatory lipids in mouse milk, which can otherwise cause inflammation, alopecia, and growth retardation in nursing pups.
