Morphogenesis of Chimeric Hair Follicles in Engineered Skin Substitutes With Human Keratinocytes and Murine Dermal Papilla Cells

This study investigated how secretions from cultured human hair follicle-derived keratinocytes affect gene expression in human follicle dermal papilla cells to understand their signaling interactions.

This study observed that earlier-passage keratinocyte cultures led to superior hair follicle neogenesis in dermal-epidermal composites grafted onto immunodeficient mice, suggesting their potential utility in studying human hair follicle development.

This review discusses the role of dermal cells in hair follicle regeneration and morphogenesis and highlights their potential therapeutic implications, but it reports no new empirical findings.

This study found that dermal papilla and sheath cells can induce hair follicle formation in vitro and in vivo by interacting with hair follicle epithelial cells.

This study found that dermal papilla cells and dermal sheath fibroblasts can induce hair follicle formation when combined with hair follicle epithelial cells, both in vitro and in vivo in nude mice.

This study demonstrated that intact adult human dermal papillae can induce hair growth when implanted into mouse hair follicles, highlighting their potential for advancing hair follicle biology and therapeutic approaches.

This research observed that dermal papilla cells have the potential to regenerate hair bulbs under preferred environmental conditions when associated with dermal sheath cells or exposed to specific growth factors.
