Protein ubiquitylation is crucial for controlling stem cell functions and could be targeted for cancer treatment.

This review explores recent advancements in understanding how various physiological and psychological factors, such as stress and aging, influence epidermal stem cell populations, highlighting their importance in immune-related skin disorders and potential for clinical applications.

This review discusses recent advances in imaging techniques for monitoring stem cells in vivo and reports no new results; it suggests directions for future development in endoscopic molecular imaging tools.

This review explores the complex, context-dependent roles of tumor-secreted proteins and suggests that some proteins traditionally seen as tumor-promotive may act as tumor-suppressors in different environments, emphasizing the influence of cell fitness and treatment exposure.

In this study, researchers found that disrupting desmoglein 3 signaling in a mouse model of pemphigus vulgaris activates normally quiescent hair follicle stem cells, compromising their multipotency but prompting a regenerative response that restores stem cell function and structures.

This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.

This study demonstrates that Wnt signaling plays a crucial mechanoregulatory role in skin regeneration by influencing cellular responses to substrate rigidity, which promotes hair follicle regeneration in the wound-induced hair neogenesis model.

This study found that micro-niches within hair follicles create heterogeneity among stem cells and transit-amplifying cells, leading to specialized progenitors that control tissue morphogenesis and regeneration.

This study found that synchronized signals in the microenvironment regulate stem cell lineage choices in hair follicles by influencing chromatin dynamics during regeneration.

This review evaluates methods to study stem cell division patterns, particularly in the mammary gland, and discusses genetic factors affecting division modalities and their implications for breast cancer, but reports no new results.

This study suggests that melanoma tumor cells exhibit intrinsic plasticity, challenging the applicability of the cancer stem cell model to this malignancy.

In this study, Hedgehog signaling in dermal papilla fibroblasts was found to accelerate hair growth and induce follicle multiplication in mice via the SCUBE3/TGF-β pathway, with some effects observed in human scalp hair follicles.

This study found that coactivating LIN28B and follistatin enhances cochlear supporting cells' ability to regenerate hair cells in neonatal mice by reprogramming them into progenitor-like cells.

This study found that manipulating Wnt/β-catenin signaling in embryonic mammary glands impacted their development, with high activity levels hindering branching and potentially redirecting cells toward hair follicle identity instead of mammary tissue.

This study found that late embryonic skin injuries can regenerate multiple tissue types, but this ability is hindered postnatally due to fibroblast-driven hyperinnervation, which can be mitigated to enable regeneration.

This study reported a new method enabling the observation of the full leg regeneration process in the crustacean *Parhyale hawaiensis* over 10 days, capturing cellular resolution while minimizing photodamage, through innovative imaging techniques and computer-assisted cell tracking.

This study found that dietary serine levels influence hair follicle stem cells' ability to balance hair regeneration and wound repair, offering insights for potential interventions to accelerate wound healing.

This study found that UV radiation-induced fibroblast depletion in the skin is primarily due to a deregulated inflammatory response, with T cells aiding fibroblast survival under stress.

Caspase-3 helps control cell growth and organ size by activating YAP.

This study found that reducing HDAC1 activity in the skin of mice led to defects in hair follicle structure and pigmentation, highlighting HDAC's role in skin and hair maintenance.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents no new clinical results.

This study describes the development of the EUSCLE Core Set Questionnaire for cutaneous lupus erythematosus, designed to standardize data collection, facilitate epidemiological analysis, and guide diagnostic and therapeutic strategies across European centers.

This study found that most pathogenic HR mutants associated with atrichia with papular lesions had abolished corepressor activity due to defective interactions with histone deacetylases.
