This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

This review discusses the use of dermal regeneration templates for treating burn injuries and other wounds, highlighting their effectiveness in reducing scars and aiding in regenerative processes, but reports no new clinical results.

This study found that the co-ablation of C/EBPalpha and C/EBPbeta in adult mouse skin disrupted sebocyte differentiation and epidermal homeostasis, highlighting their critical roles in these processes.

This study established a new mouse model for TCE-induced skin sensitization and reported that proinflammatory cytokines TNF-α, IFN-γ, and IL-2 significantly contribute to this sensitization process.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study found that in mice lacking EGFR, elevated Wnt signaling disrupts hair follicle development by affecting cell proliferation and differentiation, revealing a critical role for EGFR in regulating these processes.

This study found that P311 triggers transdifferentiation of epidermal stem cells into myofibroblast-like cells via TGFβ1/Smad signaling during wound healing.
