This paper reviews the complex pathophysiology of polycystic ovary syndrome, exploring how hormonal and metabolic disturbances contribute to its symptoms and related health risks, but it presents no new findings.

This study identified a set of wound-induced genes in planarians that play a role in regeneration initiation, with some genes specifically activating within regenerative cells called neoblasts.

This review explores recent insights into the diverse cell populations involved in skin development, homeostasis, wound healing, and cancer progression but reports no new results.

This review discusses the multifaceted actions of metformin in polycystic ovary syndrome and reports no new clinical results; the authors emphasize metformin's potential benefits in both cardiometabolic and reproductive aspects of PCOS.

This review discusses the interplay of hyperandrogenism, insulin resistance, obesity, and their role in polycystic ovary syndrome, but presents no new clinical results.

This review discusses skin-related toxicities associated with targeted cancer therapies and emphasizes the need for dermatologists to understand and manage these adverse effects, but reports no new experimental results.

This article discusses the role of estrogens in skin aging and reports no new findings; it highlights the potential of selective ER modulators to improve skin health without systemic side effects.

This review outlines various dermatologic adverse events associated with targeted therapies and immunotherapies, emphasizing the need for collaboration between dermatologists and oncologists to manage these effects effectively; it reports no new clinical findings.

This review summarizes the roles of bone morphogenetic proteins in the development and regulation of normal and diseased skin, but it does not provide new clinical results.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

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 review discusses the use of 36 medicinal plant species for cutaneous wound healing and reports no new clinical results; the authors highlight the potential for these traditional practices to inform modern therapies.

This forum article in BMC Biology discusses evolving views on the concept of the stem cell niche, highlighting varied mechanisms and the need for better understanding of the niche's roles and functions.

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 article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports 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.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

This review discusses the effects of estrogen on skin aging and highlights potential therapies, but reports no new clinical findings.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

This study summarizes how the IL-23/IL-17 axis contributes to inflammatory skin diseases like psoriasis and highlights that biologics targeting this pathway, including monoclonal antibodies against IL-23 and IL-17, have shown efficacy in clinical trials for these conditions.

This study found that aging in the epidermis disrupts cytokine balance and stem cell function, which may contribute to broader tumor-suppressive mechanisms.

This review discusses the development and potential therapeutic applications of adenosine receptor agonists and positive allosteric modulators, noting that while many clinical trials have been unsuccessful, initial results for new compounds are promising.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

This review discusses the dynamic, niche-driven regulation of stem cell states in tissue homeostasis and regeneration, focusing on epithelial stem cells in the mammalian skin, intestine, and lung, without providing new experimental 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 the advancements in intraoperative stem cell therapies and highlights their potential to improve hair regrowth, but it reports no new clinical results.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

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 review discusses the roles of TGF-β family signaling in regulating normal and cancer stem cells and highlights the need for further research to develop potential cancer treatments; it reports no new results.
