This study found that all-trans retinoic acid (ATRA) negatively affects hair growth by reducing goat dermal papilla cell viability and growth factor expression.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.

In this study, mouse amnion epithelium was successfully transformed into skin and hair follicles when associated with hair-forming dermis, revealing the necessity of specific influences for follicle formation.

This study found that NKIRAS2 expression affects skin tumor suppression and HRAS-driven transformation in mice, indicating its role in carcinogenesis depends on expression level and cellular context.

This comprehensive review suggests that CD44 signaling plays a significant role in post-natal skin wound healing and scar formation, with potential for therapeutic approaches targeting CD44 to shift from fibrotic scarring towards regenerative healing, including wound regeneration and hair neogenesis.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

This review discusses the potential of the hair follicle dermis to direct hair development and explores concepts related to hair growth and androgenetic alopecia, without reporting new clinical results.

This report suggests that TCDD may alter human epidermal stem cell populations by upregulating c-Myc, potentially leading to increased stem cell turnover during chloracne development.

This review synthesizes both traditional and emerging molecular mechanisms of tissue remodeling across different organs, aiming to establish a theoretical basis for precision interventions in pathological conditions, according to the authors.

This study investigated the possible role of neutrophil extracellular traps in contributing to fibrosis in stenotic Crohn's disease.

This review highlights the potential of amphiregulin as a therapeutic target, noting its role in both fibrotic and malignant diseases, and discusses promising early findings but reports no new clinical results.

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.

Oral retinoids are effective for severe skin conditions but require careful use due to side effects.
