The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This study found that FGF18 signaling helps protect hair follicles from radiation damage by maintaining the resting phase and supporting stem cell survival, potentially reducing radiation-induced hair loss.

Adding stem cells to fat grafts for facial rejuvenation might improve outcomes, but more research is needed to confirm safety and effectiveness.

This review discusses the challenges of skin graft acceptance and examines current strategies and alternatives for full-thickness skin replacement and repair, noting that immunological rejection remains a significant hurdle.

This study found that the retinol dehydrogenases SDR16C5 and SDR16C6 in mice play a crucial role in skin retinol dehydrogenase activity, affecting hair growth and gland functions without impacting survival.

Activin increases skin tumor formation, skin Tregs help hair growth, lymph-node removal doesn't improve melanoma survival, cells can revert to stem cells in wound healing, and skin bacteria produce peptides that may treat infections.

This study suggests that programmed cell death plays a crucial role in shaping the structure of the human epidermis and its appendages during development.

This study found that overexpression of the anti-apoptotic protein Bcl-2 in mice disrupted cell death during the hair cycle, impairing hair regeneration by delaying anagen entry and hair growth.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

In this study, only a subset of proposed biomarkers universally responded to priming in mesenchymal stromal cells, suggesting limited utility for standardized potency assays across different MSC types and conditions.

In this study, researchers found that hypoxic preconditioning significantly improved the regenerative potential of aged adipose-derived mesenchymal stem cells, enhancing their growth, differentiation, and pro-angiogenic capabilities, suggesting a promising strategy for autologous regenerative medicine applications.

This study found that mouse hair follicle stem cells use symmetric cell division for maintenance and fate determination, and identified Gata6 as a crucial factor for their differentiation.

In this study, researchers observed that a noncanonical mechanism involving the γ-secretase-dependent, RBPj-independent Notch intracellular domain improves survival in Msx2-Cre mice by delaying hair follicle destruction and reducing disease severity.

This study found that mitochondrial fusion regulator Opa1 is crucial for maintaining melanocyte stem cells during the hair follicle cycle in mice, with Opa1 deficiency leading to impaired SCF-KIT signaling, reduced melanocyte populations, and early hair graying.

This study found that valproic acid and crocin, alone or together, significantly increased the expression levels of neurotrophic factors in rat-derived epidermal neural crest stem cells, suggesting therapeutic potential for neurological disorders.

In this study, conditional deletion of BRD4 in OX40-expressing cells of mice led to alopecia, dermatitis, and loss of hair follicle stem cell function, revealing BRD4's role in skin inflammation and stem cell regulation.
