This study found that quiescent bulge stem cells, when prevented from contributing to hair follicle and epidermal regeneration, did not affect hair follicle growth or wound healing in the short term.

This study found that CD26+ fibroblasts are crucial for effective extracellular matrix production and achieving rapid epidermal and dermal homeostasis in human tissue-engineered skin substitutes transplanted onto rodents.

In this study, researchers developed a new 3D skin equivalent assay using mouse epidermal and dermal cells that successfully regenerated organized hair follicles, outperforming a 2D model in hair follicle orientation and quantity, and enhanced hair growth when Wnt3a was added.

This study demonstrates that α-parvin is crucial for epidermal morphogenesis and hair follicle development by mediating integrin-dependent adhesion and actin organization in keratinocytes.

This study suggests that epidermal turnover could be a regulated mechanism of iron excretion, with systemic iron levels influencing keratinocyte behavior and differentiation markers in the skin.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This chapter reviews therapies for skin and corneal regeneration and hair loss, discussing various treatments but presenting no new research findings.

In this study, expressing human K16 in the epidermis of K14 null mice prevented early skin blistering but led to age-related anomalies, indicating K16 and K14 have distinct roles despite their sequence similarity.

This study found that Myc activation in epidermal stem cells leads to chromatin modifications that promote stem cell exit and differentiation, which can be influenced by HDAC inhibitors like trichostatin A.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.

This study found that overexpression of activin in transgenic mice led to enhanced granulation tissue formation after skin injury due to changes in keratinocyte proliferation and differentiation.

This study found that aging in the epidermis disrupts cytokine balance and stem cell function, which may contribute to broader tumor-suppressive mechanisms.

This review discusses the classification, pathogenesis, and management of skin, hair, nail, and mucosal changes due to EGFR inhibitors, emphasizing the importance of informing patients to improve therapy compliance.

This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

This study found that downregulation of EGF and KGF signaling is necessary for hair follicle initiation in placodes, revealing a new role for KGF in hair follicle formation in mice.

This review highlights recent advances in understanding how the extracellular matrix regulates epidermal stem cell fate, emphasizing the importance of the hair follicle stem cell niche, but reports no new empirical findings.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This study found that reducing BMP signaling in mouse nipple epithelia, achieved through Noggin overexpression, can convert them into hairy skin with pilosebaceous units.

This study found that Par3 plays a crucial role in maintaining epidermal homeostasis by regulating Rho/actomyosin contractility and ensuring mitotic accuracy, with potential implications for other self-renewing epithelia.

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.

In this study, loss of epidermal Par3 in mice disrupted the skin barrier and affected cell differentiation and stem cell maintenance, highlighting its role in epidermal homeostasis.
