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 review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

This study found that polycomb-group-mediated repression plays a key role in regulating hair follicle stem cell states and lineage progression by distinct mechanisms in adult mouse skin.

This review discusses melatonin's potential in dermatology, highlighting its antioxidative, immunomodulatory, and DNA repair properties, but 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 epidermal stem cell diversity, revealing previously unrecognized differences in stem cell populations, but reports no new experimental results; it highlights the need for further exploration of stem cell interactions and quiescence.

This review discusses the pharmacology and toxicology of cyclooxygenase in skin, highlighting its role in inflammation, wound healing, and tumorigenesis, without presenting new clinical results.

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 summarizes current knowledge on tight junctions in mammalian skin and their role in drug delivery and interaction with other barrier components, but reports no new experimental results.

This study found that hair follicle stem cells initially contribute to wound re-epithelialization, but long-lasting epidermal cells are primarily derived from a stem cell population in the isthmus portion of hair follicles.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This study observed that quiescent label-retaining cells in the intestine, identified by Paneth cell markers, can switch to a proliferative state and activate Bmi1 expression during tissue injury, contributing to tissue regeneration.

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 study estimates that young adults have about 230,000 tactile afferent fibers innervating their skin, with density varying by region and decreasing with age.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.

This review explores finasteride's effects on neuroactive steroid levels and their potential influence on disorders like depression and alcohol withdrawal but reports no new clinical findings.

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.

This systematic review suggests that turmeric and curcumin products, both oral and topical, may offer therapeutic benefits for various skin conditions, though further research is necessary to evaluate efficacy more thoroughly.

This review examines the literature on the molecular and cellular makeup of the hair follicle niche and how it influences stem cell behavior during hair regeneration, but does not provide new experimental results.

GABRA2 gene variations impact alcohol response, and hair loss medication finasteride reduces some effects.

Different types of stem cells and their environments are key to skin repair and maintenance.

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.

This study found that tofacitinib led to ≥50% hair regrowth in eight out of twelve patients with moderate to severe alopecia areata, suggesting a potential benefit for using JAK inhibitors in treating this condition.

This study found that Na CMC hydrogel loaded with PEG-coated silver nanoparticles demonstrated superior antibacterial and wound-healing efficacy compared to commercial silver sulfadiazine cream in a wound-healing model.

This review discusses recent findings on the plasticity and regulation of epithelial stem cells and reports no new experimental results.

The researchers reported that dsRNA from damaged skin activates TLR3, promoting hair follicle regeneration, while TLR3-deficient animals fail to initiate this process, suggesting potential therapeutic approaches for hair neogenesis.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.
