This study found that NF-κB signaling may connect injury response to regenerative processes in zebrafish hearts, potentially aiding the development of cardiac regenerative therapies in humans.

This article reviews advances in feather development and regeneration, including pattern formation, stem cell biology, and evolution, but presents no new experimental results.

This review discusses current experimental approaches for regenerating human hair follicles using tissue engineering and isolated cells, but reports no successful strategies with adult cells yet found.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study found that both human and rat dermal papilla spheroids can induce hair follicle neogenesis, but larger spheroids increase inductivity without significantly affecting hair fiber diameter.

This review discusses the impact of menopause-related oestrogen deficiency on skin ageing and suggests that oestrogen use may improve collagen and skin elasticity, but it reports no clinical trial results.

This review discusses circadian clock regulation in stem cells and its role in processes like neurogenesis, but reports no new results; the authors emphasize its significance in stem cell function across various tissues.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.

This study demonstrates that bioengineered tooth germ autologously transplanted in a postnatal canine model can achieve functional tooth restoration, suggesting its potential for future clinical regenerative medicine.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This review discusses the roles of Wnt signaling in skin organogenesis and related processes but reports no new experimental results, highlighting areas for future research.

This study found that thyrotropin-releasing hormone (TRH) acts as a potent stimulator of hair growth in human scalp hair follicles, promoting elongation and prolonging the anagen phase.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.
