This review explores recent advances in understanding molecular mechanisms of tissue regeneration in mammals and suggests potential therapeutic targets, but it reports no new clinical results.

This article discusses the coordinated roles of different epidermal stem cells and other cell types in the skin's wound healing process and reports no new experimental results.

This study reviewed recent theories on alopecia areata's pathogenesis, highlighting its autoimmune nature due to immune privilege disruption in hair follicles, and noted current treatments have limited efficacy with high relapse rates, underscoring the need for further research into its mechanisms for better therapies.

This review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This study identified a distinct cytokine activation signature in alopecia areata, involving TH2, TH1, IL-23, and IL-9/TH9 pathways, suggesting potential targeting strategies similar to those in psoriasis and atopic dermatitis.

This review discusses the shared molecular and cellular processes in the early development stages of skin appendages like hair follicles, teeth, and mammary glands, reporting no new results.

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 review examines the functions of vitamin D and its receptor in skin and explores how these are regulated, reporting no new clinical results.

This review explores the role of TGF-β superfamily pathways in stem cell environments and their implications for tissue regeneration and cancer development, reporting no new experimental results.

This study found that mouse skin CD4(+) memory T cells are in equilibrium with the circulation under steady state but increase in specific clusters in response to infection or inflammation.

This review reports that alopecia areata affects about 2% of people globally and is linked with psychiatric and medical comorbidities, highlighting its significant disease burden.

This review discusses the molecular mechanisms by which oncogenic viruses contribute to cancer development through manipulation of host cellular functions and highlights the need for further research into virus-associated cancers, reporting no new results.

This review explores the impact of vitamin D deficiency on the skin from a dermatological perspective, but reports no new clinical results.

This review explores the potential of periodontal ligament stem cells for regenerative therapy in periodontium, despite challenges due to their rarity, and reports no clinical results.

This review discusses how Western diet may contribute to acne vulgaris through insulin signaling and metabolomic changes, promoting a dietary approach for management, but reports no new experimental results.

This review explores how adipose-derived stem cells contribute to skin homeostasis and highlights recent advances in their clinical applications in dermatology, but it reports no new clinical 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 review suggests that understanding the biological and molecular reasons for more severe COVID-19 in men, particularly those at risk for prostate cancer, could improve management of these patients, but reports no new results.

This review examines the adaptive value and mechanisms of seasonal coat colour moulting in birds and mammals, highlighting the challenge of camouflage mismatch and the necessity for evolutionary adaptation under climate change.

This study found that skin-derived precursor cells in mice can originate from both neural crest and somite lineages but show functional similarities regardless of their developmental origins.

This review discusses the role of immune privilege collapse in the pathogenesis of alopecia areata, emphasizing the potential for therapeutic manipulation of hair bulb immune privilege to offer new treatment options, and reports no new results.
