This review discusses the clinical features of SARS in children, noting milder symptoms compared to adults, and emphasizes the importance of ongoing monitoring for long-term effects; it reports no new treatment findings.

This review explores recent findings on the roles of melanocyte and melanocyte stem cells in the hair follicle, highlighting their importance for skin health and potential applications in regenerative medicine, but reports no new clinical results.

This review discusses post-SSRI sexual dysfunction and post-finasteride syndrome, highlighting unknowns about their true incidence and underlying causes, and reports no new clinical results.

In this study, researchers found that intestine-derived human alpha defensin 5 enhances wound healing, reduces bacterial load, and promotes hair growth in murine burn wound beds by increasing LGR stem cell migration.

This review highlights that while dexamethasone may reduce mortality in severe COVID-19, no other drugs have proven effectiveness for treatment, emphasizing the need for clinical trials of existing medications.

This workshop review discusses the dual role of cellular senescence in cancer, highlighting both its anticancer effects and pro-tumorigenic potential, while reporting no new research results.

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 found that different species metabolized minoxidil into various products, with monkeys and humans showing similar profiles primarily excreting a glucuronide conjugate, while rats and dogs showed distinct differences.

This study found that the PI3K-Akt signaling pathway is essential for regenerating new hair follicles when epidermal stem cells and skin-derived precursors are combined, suggesting potential therapeutic applications for hair regeneration.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This study suggests that adipose-derived mesenchymal stem cells from diabetic mice can enhance wound healing by promoting fibroblast growth, migration, angiogenesis, and differentiation into fibroblasts and endothelial cells.

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.

The article concludes that the global hair trade is exploitative and reflects complex cultural and economic issues.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This review examined dermatologic symptoms associated with COVID-19 in 2,560 patients, with chilblains/pernio-like lesions being the most common, suggesting these symptoms may aid in early identification of cases.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This review discusses the generation of germ cell-like cells from skin-derived stem cells and reports no new results; the potential for these cells to produce viable progeny remains unclear.

This review discusses the mechanisms governing epidermal stem and progenitor cell differentiation, emphasizing the balance necessary for maintaining skin barrier function, and reports no new experimental findings.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents no new clinical results.

In this study with stumptailed macaques, topical minoxidil successfully induced hair regrowth on bald scalps and prevented baldness on non-bald scalps, with no observed side effects over nearly three years.

In this study, researchers discovered that ROR2, a Wnt receptor, plays a crucial role in regulating hair follicle stem cell self-renewal and maintenance, compensating for the absence of β-catenin.

In this study using diabetic rat models, the combination of AMD3100 and low-dose FK506 reduced wound healing time and improved microcirculation in diabetic foot ulcers, indicating a promising new systemic therapy.

This review summarizes current genetic knowledge of alopecia areata and provides a theoretical framework for future genetic mapping studies, but reports no new results.

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 insulin promotes corneal epithelial wound healing and nerve recovery in diabetic mice through Wnt signaling, suggesting its potential as a protective factor for diabetic corneal damage.

In this study, full-thickness wounding on Lanyu pigs led to scar formation and disrupted cell markers, while partial-thickness wounding allowed limited regeneration of rete ridges and papillary dermis.

This review discusses the flexibility and diversity of tissue stem cell systems, particularly focusing on the motility and ligand distribution of spermatogenic stem cells, without presenting new experimental results.

This study introduced a new adaptive microrhizotron for non-destructive observation of pepper root traits, finding that specific installation patterns significantly enhanced root interception probability while effectively measuring root architecture for plant research.
