This study found that cultured mouse dermal papilla (mDP) cells can induce hair follicle neogenesis in de novo regenerated skin tissues grafted onto mice.

This essay discusses the role of the nail in mammalian digit tip regeneration and explores whether nail stem cells are solely responsible for this regenerative ability, with no new results presented.

This review explores the regenerative potential of hair follicles and their role in complete skin regeneration, emphasizing the influence of mechanical factors and niche signaling pathways on hair growth and loss.

This review discusses advances in 3D bioengineering technologies for regenerating complex oral organs and suggests they could play a key role in future organ replacement therapy.

In this study, researchers observed that during zebrafish fin regeneration, osteoblast Erk activity, influenced by Fgf receptor signaling, forms gradients scaling with amputation length, which predicts regenerative tissue growth and skeletal structure size.

This review discusses the developmental plasticity between teeth and taste buds in cichlid fishes and reports no new experimental findings, highlighting potential implications for craniofacial organ patterning and regeneration.

This study observed that mature neutrophils and their extracellular traps inhibit wound-induced hair follicle neogenesis in mice, despite being stimulated by pro-regenerative cues.

This study used scRNA-Seq to map the transcriptional changes during zebrafish hair cell regeneration, revealing distinct phases including injury response, transient regeneration gene activation, and reactivation of developmental programs.

In this study, researchers found that inhibiting YAP signaling in skin wounds leads to regenerative repair with active Trps1 and Wnt signaling, contrasting the typical fibrotic scarring process.

In this study, researchers found that disrupting desmoglein 3 signaling in a mouse model of pemphigus vulgaris activates normally quiescent hair follicle stem cells, compromising their multipotency but prompting a regenerative response that restores stem cell function and structures.

This study found that in spiny mice, the proximal side of ear wounds is crucial for regeneration, a process possibly linked to unique injury-induced immune responses compared to nonregenerative rodents.

This review highlights exosomes as a promising treatment for skin damage from UV light, infrared radiation, burns, and disorders due to their anti-inflammatory properties, ability to induce macrophage polarization, and acceleration of skin repair and regeneration.

This study found that sustained ERK activity during tissue regeneration in spiny mice is linked to fibroblast growth factor and ErbB signaling, while inhibiting ERK shifted regeneration toward scarring.

This study found that wounding in skin induces significant fibroblast heterogeneity and recruits myeloid cells, which contribute to adipocyte regeneration in mice.
