Mycophenolic acid may help hair grow by activating pathways important for hair growth.

Alopecia totalis/universalis involves more intense immune activity and inflammation than patchy alopecia areata.

This article discusses the role of the American Society of Plastic Surgeons in plastic and reconstructive surgery education but presents no new research findings.

This study found that a new "bead-jet" printing system for mesenchymal stem cells in Matrigel beads improved skeletal muscle regeneration and skin healing in a high-density, sparse pattern.

This study found that leptin acts as an inducer of the anagen phase in hair follicles, suggesting its role as a potential player in hair biology.

This study found that mechanical and chemical interactions in skin organoids are crucial for initiating mesenchymal-epithelial interactions necessary for hair follicle regeneration.

In this study, researchers developed a near-infrared-responsive nanoplatform that synergistically enhances chronic wound healing by accelerating mitochondrial restoration and immune modulation, leading to enhanced wound repair and high-quality healing in diabetic rat models.

This study found that tissue damage in adult mice triggers the release of mitochondrial DNA, which activates the TLR9 pathway and influences hair regeneration by recruiting gamma delta T cells, ultimately affecting healing outcomes such as fibrosis.

This study found that BMP-2 activates Dlx3 gene transcription in murine keratinocytes by binding with Smad1/Smad4, suggesting a mechanism for BMP signaling's role in skin and hair follicle regulation.

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 RSPO1, a Wnt/β-catenin pathway agonist, significantly induces insulin-producing β cell replication and neogenesis in various settings, offering a promising potential therapy for diabetes.

This study shows that the Wnt-β-catenin pathway promotes TERT expression in both stem and cancer cells, linking tumorigenesis with pluripotency.

This study found that gastrodin promotes the XIAP-DDRGK1 pathway in noise-exposed mice, reducing hearing loss by enhancing ER-phagy and cochlear cell survival.

This study found that activating both PKM2 and Wnt/β-catenin signaling pathways significantly enhanced hair regrowth and hair follicle neogenesis in mice, suggesting a potential strategy for treating alopecia.

This research found that metformin promoted hair growth in vitro by activating the AMPK/β-catenin signaling pathway in dermal papilla and outer root sheath cells.

This study reported that administering salicylates to wounds in adult mice promoted wound healing patterns similar to embryonic wounds, enabling complete wound regeneration and reduced scarring by activating AMPK and subsequent signaling pathways.

This study reported the establishment of a chemically defined culture system that supports tooth reconstitution and detailed how co-stimulation of specific signaling pathways can sustain tooth development stages and initiate enamel formation, providing insights into tooth regeneration mechanisms.

In this review, researchers concluded that chronic inflammation perpetually activates stem cells, allowing DNA damage accumulation and potentially promoting cancer development and metastasis by converting stem cells into cancer cells.

This narrative review explores how psychological stress may contribute to premature skin aging by affecting dermal collagen and elastin remodeling through neuroendocrine, molecular, and cellular pathways, highlighting potential therapeutic targets to preserve skin structure and function.

This study found that resveratrol and fisetin promoted hair growth in mice by inducing telomerase reverse transcriptase expression, which activates hair follicle stem cells and transitions follicles from a resting to a growth phase.

This study reported that, in a laboratory setting, araliadiol derived from Centella asiatica activated antioxidant pathways, mitigating urban particulate matter-induced oxidative stress and skin damage.

This study found that mammary resident macrophages play a key role in mammary tissue development by influencing cell division and maintaining mammary stem cell activity through the TNF-α-Cdk1/Cyclin B1 signaling pathway, highlighting their importance in the mammary stem cell niche.

This study found that hair follicle stem cells are stiff with high actomyosin contractility, while hair germ progenitors are soft and enlarge during quiescence, influencing hair regeneration; inducing miR-205 reduces contractility and activates regeneration in mice.

In this experimental study, the researchers observed that Platycladus orientalis leaf extract promoted hair growth by enhancing dermal papilla cell proliferation and increasing growth factor expression, particularly through ACK1 activation and modulation of Wnt/β-catenin signaling pathways in cultured human cells and a 12-week topical application.

This article reviews how the skin's peripheral stress response system mirrors the central HPA axis, facilitating local homeostasis under stress, but presents no new findings.
