This study found that dermal papilla cells may play a critical role in hair follicle development and cycling by promoting epidermal proliferation and potentially mediating systemic factors that influence follicle behavior.

This study found that engineered reconstituted skin can form morphogenetic units that promote tissue patterning and hair regeneration, with certain signaling pathways restoring this ability in adult and fetal cells.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

This study found that mechanical and chemical interactions in skin organoids are crucial for initiating mesenchymal-epithelial interactions necessary for hair follicle regeneration.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

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

This study used digital-light-processing bioprinting to create a 3D skin-on-a-chip model with a miniaturized vascular network to closely study immune cell interactions similar to real human skin, demonstrating the potential to analyze immune-T cell trafficking influenced by skin signals.

This study concluded that human epidermal stem cells cultured in MEM-α and EpiLife media with growth factors show high proliferation potential and plasticity, suggesting potential use in skin regenerative medicine.

In this study, a dual-layer electrospun nanofibrous mat incorporating chitosan nanoparticles, growth factors, and hair follicle bulge stem cells significantly enhanced wound healing in a rat model.

This study demonstrated that a mechanical-chemical cascade involving dermal cell contraction and the activation of Piezo1 in epidermal cells is crucial for initiating interactions necessary for hair follicle regeneration in skin organoids.

In this study, gene inactivation in mouse hair follicle stem cells lacking ILK impaired wound healing by reducing their progeny’s contribution to the regenerating epidermis, but did not affect hair follicle regeneration.

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.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

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.
