This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This article discusses the roles of epidermal stem cells in maintaining skin homeostasis and highlights how deregulation in signaling pathways may lead to cancer, but it reports no new experimental results.

This review discusses the progress in identifying stem cells responsible for tissue regeneration and highlights technological advances in tracking their behavior, but reports no new clinical results.

Hedgehog signaling helps keep hair follicle stem cells the same in both young and old human skin.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This study found that Brg1, a chromatin-remodeling enzyme, plays a critical role in hair regeneration and early epidermal repair by regulating bulge stem cells through a Brg1-Shh interaction.

Mitoxantrone is effective for treating acute leukemia, especially in older patients, with a lower risk of heart damage.

This review discusses the emerging roles of transit-amplifying cells in tissue regeneration and cancer formation, highlighting their significance beyond a mere transitional state in hair follicles and the hematopoietic system.

This review discusses the role of stem cell heterogeneity and compartmentalization within the epidermis and highlights their significance as niches for neighboring cells, without reporting new experimental results.

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 study found that deletion of c-Jun and JunB in mouse bulge hair follicle stem cells was sufficient to trigger psoriasis-like skin disease through thymic stromal lymphopoietin signaling.

This study found that the postnatal thymus contains a population of mesenchymal stem cells that may help maintain functional thymic microenvironments.

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 study found that single high-dose irradiation in mice induced more severe acute skin injury and hair depigmentation, while fractional doses led to longer-term damage in the dermis and subcutis.

In this study, basal cell carcinoma developed in Ptch-deficient mice only after chemical treatment, not skin wounding, suggesting a second unknown event is necessary for tumor formation.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study found that a newly identified mutation in the hairless gene in mice led to decreased Hr mRNA levels and changes in gene expression related to hair follicle development.

This review examines the challenges of hair follicle regeneration and outlines strategies for bioengineering human hair follicle models, without presenting new experimental results.

This review highlights surprising similarities between hair follicles and antler units, suggesting that a comparative study of their biology could benefit understanding in both areas without presenting new empirical findings.

This meeting in Heidelberg highlighted diverse contributions on stem cell research, including pre-clinical and clinical applications, but reported no new experimental results.

This study observed that disrupting the Pnkp gene in adult mice resulted in a premature aging-like phenotype, suggesting PNKP's vital role in maintaining normal growth and survival of certain progenitor cell populations.

In this study, 5α-reductase inhibitors were found to have no significant impact on preventing tumorigenesis or progression in in vitro models of urothelial cancer.

This review discusses investigational treatments for androgenetic and chemotherapy-induced alopecia and reports no new clinical results, highlighting the need for further research.

This study found that β-catenin stabilization in specific mammary epithelial lineages leads to cellular changes and the formation of hyperplastic lesions, revealing its role in initiating mammary neoplastic development.

This chapter reviews classic regeneration models in planarian worms and amphibian limbs, focusing on the role of stem cells, and reports no new experimental results.

Skin aging reflects overall body aging and can indicate internal health conditions.

This case series provides anecdotal evidence that urinary bladder extracellular matrix may improve hair regrowth in donor scars and enhance hair follicle graft outcomes in hair restoration surgery.

This paper reviews the role of ATP-dependent chromatin remodeling complexes in epidermal homeostasis, hair regeneration, and skin repair, noting contributions to 3D-genomic organization and suppression of UV-induced hyper-proliferation, without presenting new results.

This study found that αvβ6 integrin inhibits keratinocyte proliferation during wound healing and hair regeneration, suggesting its downregulation may enhance recovery and influence epidermal stem cell behavior.
