This study used 3D bioprinting to implant epidermal stem cells, skin-derived precursors, and Matrigel into mouse wounds, successfully regenerating hair follicles and skin components within four weeks, with minimal impact on stem cell viability and stemness.

In this study, researchers demonstrated that zero valence fluorescent gold nanoclusters can be biosynthesized in damaged skin and inhibit hair follicle regeneration by affecting the NFκB inflammatory response pathway, suggesting potential as a treatment for hypertrichosis related to skin injury.

In this study, researchers found that a cold atmospheric plasma-activated hydrogel containing interleukin-2 significantly enhanced hair regeneration in a depilated mouse model, promoting larger hair follicles and faster hair growth phase transition, suggesting it as a potential treatment for hair loss.

This review discusses the development and future prospects of biomaterials for in situ tissue regeneration but reports no new research results; it underscores the importance of biomaterials in addressing tissue defects.

This study found that a bioprinted hydrogel scaffold with zinc and silicon ions significantly activated hair follicle stem cells and enhanced blood vessel formation, promoting hair growth in mouse wound models.
