This review discusses the complex pathophysiological and clinical aspects of COVID-19, including dermatological findings and their association with SARS-CoV-2 infection but reports no new clinical results.

This review discusses updated treatment guidelines for alopecia areata in Japan, highlighting new options like corticosteroid pulse therapy, but reports no new clinical results.

This review discusses the varied roles of Wnt7a in development, tissue homeostasis, and cancer, reporting no clinical results; the authors emphasize the need for further investigation on its roles in inflammation and fibrosis.

This review discusses epigenetic mechanisms in tissue repair across species and summarizes recent CRISPR-based technologies as promising tools for studying and enhancing tissue regeneration, but reports no new experimental results.

This article reviews the identification and assessment of cutaneous drug reactions, emphasizing the importance of early recognition and the need for accurate diagnosis to prevent serious complications; it reports no new clinical results.

Pregnancy can cause skin changes and affect existing skin conditions, with limited treatment options due to the need for fetal safety.

This study found that facial sun damage scores from UV photography correlate with skin cancer and melanoma risk factors, suggesting this technology may help identify individuals at higher risk.

This review discusses the roles and characteristics of skin stem cells, their niches, and signaling pathways in skin maintenance, aging, and cancer, highlighting their potential in therapeutic applications but presenting no new clinical findings.

This review discusses historical and recent advances in understanding the embryonic organizer's role in patterning during development, including molecular pathways and future research challenges, but reports no new experimental data.

This research found that activating a KrasG12D mutation in mice led to skin thickening, papillomas, and hair growth issues, suggesting that even rare KRAS mutations can mimic human RAS/MAPK syndrome symptoms.

This research reports that paternal finasteride treatment in male rats may negatively impact liver function in their male offspring, as observed through altered expression patterns of ERα and PCNA in liver tissue across different developmental stages.

This study found that folliculin deficient renal cancer cells were more sensitive to irradiation due to increased autophagic cell death, suggesting a potentially enhanced therapeutic approach when combined with autophagy inducers like rapamycin.

This study observed that VEGF165 increases proliferation and migration but alters adhesion properties of cultured human hair follicle cells, indicating a potential role for VEGF/VEGFR-2 in hair follicle regulation beyond angiogenesis.

Overexpressing the epigen gene in mice leads to enlarged sebaceous glands and greasy fur.

This study suggests that interleukin-1 α influences dermal papilla cell activity by modifying androgen receptor expression and increasing the secretion of several growth factors and cytokines.

This study demonstrated that sodium valproate accelerates skin healing and reduces necrosis in a rat model of skin flap potentially through mechanisms involving GABA and histone deacetylase pathways.

This study found that human hair follicle-derived mesenchymal stem cells maintained their proliferation and differentiation potential when cultured with acidic fibroblast growth factor, basic fibroblast growth factor, or epidermal growth factor.

This study reports that adipose-derived stem cells can protect against radiation-induced dermatitis in rats by reducing apoptosis through lowering Cathepsin F expression, suggesting a potential new therapeutic approach.

In this study, ALR was found to enhance both the proliferation and osteogenic differentiation of mouse bone marrow mesenchymal stem cells, potentially through specific signaling pathways.

In this study, CRH receptor antagonists from Pulsatilla chinensis reversed stress hormone-induced changes in hair follicles and dermal papilla cells in a lab setting, suggesting potential pharmaceutical and cosmetic applications for treating stress-related hair loss.

This study found that sorafenib increased mast cell number and degranulation in skin, suggesting PI3K signaling and SCF production may underlie its adverse cutaneous reactions.

This study found that in Arabidopsis root hairs, mild chitosan treatment triggered callose deposition and slowed growth, while a higher concentration inhibited growth without callose deposition, indicating different responses based on chitosan concentration.

Tanshinone Capsule may help regrow hair by boosting specific cell signals.

In this study, Ageratum houstonianum ethanolic extract and its active component agerarin were found to promote hair growth and follicle elongation by increasing SCUBE3 expression via activation of MAPK–AP-1 signaling in human dermal papilla cells, suggesting potential therapeutic value for treating hair loss.

This study found that fibroblasts from Emery-Dreifuss muscular dystrophy patients with certain genetic mutations overexpress markers of fibrosis, and gene correction techniques reduced fibrogenic molecule expression in cell models, suggesting potential therapeutic applications.

This study observed that the herbal extract WJWE promoted hair growth and protected hair follicle cells in a DHT-induced murine model of androgenetic alopecia, potentially by engaging the SIRT1/JNK/p38 MAPK and Wnt5A/β-Catenin signaling pathways.

In this study, human hair follicle-derived mesenchymal stem cells promoted Achilles tendon repair in rabbits by upregulating collagen types I and III, suggesting potential as a treatment for tendinopathy.

This study found that lysophosphatidic acid increases mesenchymal stem cell proliferation and migration through signaling pathways and reactive oxygen species, implicating potential applications in stem cell expansion.

This study found that minoxidil suppressed androgen receptor functions and stability, suggesting its potential use in treating diseases related to the androgen-AR pathway.

In this study, Waved-5 mice with reduced EGFR signaling showed nearly normal skin and hair follicle function but experienced a transient reduction in subcutaneous fat.
