This review discusses multiple pathways through which exosomes may regulate skin functions and diseases like melanoma, scleroderma, and pigmentation disorders, without providing new clinical results; future therapeutic strategies are suggested.

In this study, Cyanidin 3-O-arabinoside was found to protect against DHT-induced dermal papilla cell senescence and mitochondrial dysfunction in androgenetic alopecia, restoring hair growth in mouse models.

This study found that ILK/ELMO2 complexes in epidermal keratinocytes are selectively activated by epidermal growth factor to induce cell migration, unlike with other growth factors.

This study found that the Wnt-β-catenin pathway directly promotes TERT expression in both stem and cancer cells, highlighting a mechanistic link between tumorigenesis and pluripotency.

This study found that the PSEN1-P242LfsX11 mutation in hidradenitis suppurativa influences cytokine and chemokine expression in macrophages, potentially affecting inflammatory responses.

This study found that beta-caryophyllene enhanced re-epithelialization in cutaneous wounds of female mice, suggesting its potential for improving wound healing through multiple pathways.

This study identified a novel mechanism by which dsRNA-induced TLR3 activation and retinoic acid pathways contribute to new hair follicle formation after deep wounds in mice and suggested a similar potential in humans.

This study demonstrated that customized microneedle arrays can precisely induce targeted hair regeneration and improve hair quality in mice, potentially offering a personalized treatment approach for hair loss.

This chapter discusses stem cell activity in feather and hair follicles, emphasizing how stem cells maintain their population by cycling between quiescence and activation in specialized niches but reports no new results.

This review discusses the potential regulation of signal transduction pathways by microRNAs in animal cells, aiming to identify biological processes that may be influenced by miRNA-mediated regulation, but it reports no new experimental outcomes.

This study found that applying topical imiquimod during mid and late telogen in mice activates hair follicle stem cells and influences immune cell infiltration, promoting hair cycle entry independently of Wnt signaling.

This study found that PRC2 plays a non-instructive role in adult hair follicle stem cells, with its loss not affecting quiescence or cell identity, despite upregulation of genes linked to activation.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This study suggests that Keratin 15 expression in stratified epithelia may be regulated by two distinct mechanisms involving PKC/AP-1 pathway for differentiation and FOXM1 for basal cells, challenging its reliability as a sole stem cell marker.

This review presents an overview of the integrated organ systems involved in wound healing and reports no new findings; the authors emphasize the roles of blood coagulation, immune response, and cellular mechanisms in tissue repair.

This study found that in mice, dermal adipocytes initiate inflammation and aid repair after skin injury by releasing lipids, suggesting a role in managing inflammatory diseases and impaired wound healing.

This review examines the regeneration capabilities of skin, oesophagus, and oral mucosa, highlighting the oral mucosa's unique scarless healing properties and the potential of cell therapy to improve scar reduction in wound healing.

This review discusses current and experimental treatments for cutaneous wounds, emphasizing cell-based therapies and skin transplantation, but reports no new clinical results.

This study found that thymic stromal lymphopoietin (TSLP) promotes hair growth after skin injury by enhancing the proliferation of specific stem cells in hair follicles.

This review discusses the multiple factors contributing to skin aging, including cellular changes and environmental influences, and highlights its recognition as a disease with significant implications beyond cosmetic concerns, without reporting new research results.

This review explores the potential link between psoriasis and metabolic syndrome, focusing on how disturbances in growth factors may connect these conditions and contribute to symptoms like keratinocyte proliferation and inflammation.

This study summarizes the role and potential applications of stem cell exosomes in skin and bone healing, highlighting their regenerative capabilities and suggesting innovative delivery methods like nanoliposomes and hydrogels to improve bioavailability and therapeutic outcomes.

This review discusses cutaneous extramedullary haematopoiesis and its potential mechanisms but reports no new clinical findings.

This review examines current understanding of hair graying and suggests it may be caused by depletion of melanocyte stem cells due to genotoxic stress or dysfunctional melanocytes from oxidative stress.

Ovol2 is essential for normal skin and hair regeneration.

This study concluded that using human umbilical cord blood mononuclear cells transfected with VEGF and FGF2 genes enhances skin wound healing in rats, demonstrating greater wound revascularization compared to controls.

In this review, it is discussed how mesenchymal stem cell aggregation plays a crucial role in organ development and has potential applications in organ regeneration through tissue engineering.

Two studies in Cell Stem Cell reported that human and mouse somatic cells can be reprogrammed into induced pluripotent stem cells using microRNAs, eliminating the need for ectopic protein expression.

This study reports that sebaceous glands can regenerate after injury through stem cell plasticity, with hair-follicle-derived stem cells replacing sebaceous gland progenitors and playing a crucial role in the regeneration process, which is dependent on FGFR2 signaling and aided by hair growth induction.

This study found that stabilizing β-catenin in a specific mouse model led to temporarily increased hair density but ultimately accelerated hair follicle aging and hair thinning.
