This study found that adult mouse dermis can be reprogrammed by epidermal cues to resemble neonatal dermis, with changes in fibroblast proliferation and extracellular matrix composition.

In this study, researchers found that hair follicle orientation in Fz6 −/− mice is disrupted and that hair may reorient itself over time through a self-organized process.

Healthy mitochondria in skin cells are essential for proper hair growth and skin cell interaction in mice.

This review examines the potential of plant-derived exosome-like nanovesicles in dermatology, highlighting their bioactive properties and discussing challenges to their clinical application, but does not provide new clinical results.

This study found that radiation-induced salivary gland dysfunction in mice involves microvascular damage mediated by ceramide and reactive oxygen species, suggesting ROS scavengers could protect salivary function during radiotherapy for head and neck cancer.

In this review, biomaterial-based mechanical strategies were highlighted for their potential to enhance skin regeneration and promote scarless repair, though a comprehensive understanding of their underlying mechanisms is still needed for broader application.

This study found that PRP injections improved hair density, quality, and thickness in males with androgenic alopecia compared to placebo, with reported high patient satisfaction and no major side effects.

This study extended a skin diffusion model to include a porous pathway, effectively explaining the permeability of both polar and lipophilic solutes through the stratum corneum.

This review discusses molecular and cellular strategies to improve muscle and skin regeneration and reduce scarring after cleft lip repair, offering potential benefits for function and aesthetics.

This study using Mendelian randomization in UK Biobank data suggests that lifelong increased free testosterone may have mixed effects, including increased bone density and prostate cancer risk, warranting well-powered trials to address uncertainties.

This study found no significant benefit from PRP injections for treating androgenetic alopecia in men, highlighting the need for larger, well-designed trials to assess its effectiveness and safety.

In this study, in vitro and in vivo models showed that chrysin enhanced the efficacy of docetaxel and reduced its adverse effects in non–small cell lung cancer treatment.

This review examines melatonin's potential effects on human skin and hair follicle pigmentation, highlighting the need to confirm findings from cell cultures in physiological tissue contexts.

In this study, researchers demonstrated that the expression of the oncogene SmoM2 leads to basal cell carcinoma in the ear epidermis of mice but not in the back skin, with differences in susceptibility linked to the composition of the extracellular matrix.

In this study, blue light therapy at a specific wavelength increased hair density and shaft width in 90% of patients with androgenetic alopecia after 10 weeks.

This meta-analysis suggests that stem cell therapy may reduce burn wound area and improve healing-related factors in preclinical models, indicating potential for future clinical studies on burn treatment.

In this study, women with PCOS who took 12 mg of Astaxanthin daily for 8 weeks showed a reduction in certain inflammatory markers and apoptosis-related genes, suggesting potential benefits for managing PCOS, though effects on symptoms like BMI and hirsutism were not significant.

This study found that a single intradermal injection of Hair Stimulating Complex significantly improved hair growth in men with androgenetic alopecia compared to placebo.

This study found that vitamin D receptor expression is associated with proliferating keratinocytes, while retinoid X receptor α is linked to differentiating keratinocytes, suggesting differential targeting by vitamin D metabolites.

This review highlights the critical role of neuroregulation in skin wound healing, emphasizing how neurotransmitters and neuropeptides regulate inflammation, angiogenesis, and cell proliferation, and discusses potential therapeutic strategies, such as neuromodulation, to enhance these processes.

This study found that injecting hepatocyte growth factor-enhanced hair follicle stem cells into a rat model of ischemic stroke improved recovery by reducing inflammation, protecting the blood-brain barrier, and promoting angiogenesis.

This review outlines the role of mechanical forces in the development of sensory organs like eyes and ears, emphasizing insights from recent animal studies and microfabricated organoid systems; it presents no new experimental results.

This study generated a gene-edited cashmere goat with improved cashmere yield and fiber length by integrating VEGF at the FGF5 site, offering insights into hair growth mechanisms.

This study reports that a single transplantation of autologous stromal vascular fraction significantly increased hair density and keratin score in androgenic alopecia patients within six months.

This study found that TGF-β2 may enhance collagen expression and spheroid formation in human dermal papilla cells, which could improve their hair inductivity and maintenance.

This study found that dietary pyridoxine increased hair follicle density in Rex rabbits by activating PI3K/Akt, Wnt, and Notch signaling pathways, which may promote hair growth and delay telogen onset.

This review discusses the strengths and weaknesses of existing studies on complex dietary supplements for hair loss, emphasizing the need for valid measurement methods like TrichoScale® to quantify effectiveness; it reports no new results.

This meta-analysis found that platelet-rich plasma treatments significantly increased hair density in patients with androgenic alopecia, with results influenced by treatment frequency and patient age.

This study found that epithelial cells in the skin of live mice regulate the density and spatial organization of immune cells, which actively maintain their position despite constant cell turnover.

In this study, treatment with cell-derived nanovesicles from hair follicle mesenchymal stem cells improved photoaging signs in UVB-exposed mice and human dermal fibroblasts by reducing oxidative stress, enhancing cell proliferation, and promoting extracellular matrix production.
