ADSCs Inhibit Photoaging and Photocarcinogenesis-Related Inflammatory Responses and Extracellular Matrix Degradation

This review discusses hair follicle stem cells for wound healing and reports no new clinical results, noting their potential but emphasizing the need for further understanding and safety in clinical applications.

This study found that miR-339-5p negatively regulates loureirin A-induced differentiation of hair follicle stem cells, potentially impacting skin repair and regeneration by inhibiting the Wnt/β-catenin signaling pathway.

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 UVB irradiation alters skin stem cell niches leading to signs of photoaging, which may be reversed by adipose-derived stem cells through BMP4 pathway modulation and niche remodeling.

This study observed that skin stem cells in dogs could be identified using CD34 and CD200 markers, although further refinement in isolation and cultivation methods is needed for better identification.

In this study, targeted overexpression of the BMP receptor ALK2 in mouse hair follicle stem cells altered follicle structure and impaired cutaneous wound healing.

This study found that Wnt7a-containing conditioned medium from UC-MSCs can accelerate wound healing and promote hair follicle regeneration by enhancing specific cellular functions in the wound microenvironment.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This review discusses how macro-environmental factors such as intradermal adipose tissue and sex hormones influence hair and feather stem cell niches, suggesting environmental targets for regenerative medicine, but reports no new clinical results.

This study found that quiescence in hair follicle stem cells acts as a tumor suppression mechanism for cutaneous squamous cell carcinoma, with Pten activity necessary to maintain this state.

This review discusses recent findings on hair follicle morphogenesis and regeneration, focusing on molecular signals and stem cells, and suggests that understanding these processes may aid in developing new strategies for wound healing.
