This study found that in wound-induced hair neogenesis, African spiny mice and laboratory mice exhibit different morphogenetic field formation patterns related to tissue stiffness, suggesting evolutionary developmental biology advantages.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This review discusses novel molecular techniques in skin appendage research and summarizes the distribution of key molecules, but it reports no new experimental results.

The authors reviewed cases of six children with both hair-shaft abnormalities and neurological disorders, noting that such hair defects may indicate neurological conditions, including potentially treatable metabolic errors.

Scientists turned rat thymus cells into stem cells that can help repair skin and hair.

In this study, engineered skin substitutes containing murine dermal papilla cells developed hair follicle-like structures when grafted onto mice, suggesting a model for generating chimeric hair.

Hair follicle stem cells can become heart muscle cells.

This study found that their system effectively supports the rapid formation of human hair follicle organoids, providing a platform for studying hair regeneration and drug screening.

This study reported that human hair follicles containing pluripotent stem cells can differentiate into cardiac muscle and other cells, indicating their potential for future clinical applications in heart and nerve regeneration.

This study found that Foxn1-like genes in fish and mice are functionally equivalent in activating hair keratin genes, whereas changes in the cephalochordate Foxn1-like gene result in inactivity.

Hair growth and pigmentation in mice involve specific stages crucial for research.

This review highlights the potential of in vivo reprogramming using OSKM transcription factors for developing rejuvenating and regenerative strategies, while noting the associated risk of tumorigenicity and discussing how improved understanding could lead to safer applications.

This study found that T cytokeratins appear more gradually and with complex coexpression patterns in developing nail structures compared to the more abrupt transition in hair follicles.

This study achieved regeneration of hair follicle-like structures and erector muscle of hair in vitro by simulating cellular organization and applying mechanical stimuli.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This study found that the transcription factor Trps1 acts as a novel regulator of the Wnt signaling pathway and early hair follicle progenitors in developing vibrissa follicles in mice.

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 found that generating pluripotent stem cell-derived skin organoids in a 3D bioprinted hydrogel device improved keratinocyte differentiation and hair follicle formation while reducing necrosis.

This study suggests that a newly discovered protein, AMY117, found in Alzheimer's disease brain lesions may be crucial in the disease's development and progression.

This study found that late embryonic skin injuries can regenerate multiple tissue types, but this ability is hindered postnatally due to fibroblast-driven hyperinnervation, which can be mitigated to enable regeneration.

This study observed that melanogenesis in human hair follicles is linked to anagen phases, with melanocyte activity and enzyme expression being region-specific to the nascent bulb.
