This review discusses the interplay between signaling/transcription factor-mediated and epigenetic mechanisms in skin development and regeneration, highlighting the need for further exploration of epigenome reorganization in these processes.

The document concluded that stem cells are crucial for skin repair, regeneration, and may help in developing advanced skin substitutes.

This review discusses the emerging pathophysiological factors and potential new therapies for androgenetic alopecia beyond traditional treatments, but reports no new results.

This study found that STAT3 directly inhibited the activity of the sheep FST gene promoter, consequently reducing cell proliferation and promoting a better understanding of hair follicle development mechanisms.

This review discusses the molecular mechanisms involved in hair follicle development and regeneration, highlighting findings from mouse genetic studies, and reports no new experimental results.

This study found that Activin B at 10 ng/mL may promote vibrissae follicle growth in mice by enhancing hair matrix cell proliferation and cell cycle progression via ERK signaling pathways.

This study found that activin A significantly enhances wound healing by stimulating granulation tissue formation and re-epithelialization in mice, and suggests potential in developing treatments for stroke and brain trauma.

In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

This study found that MED1 plays a role in maintaining keratinocyte quiescence and hair follicle stem cell populations, as its absence in mice led to increased keratinocyte proliferation and reduced stem cell numbers.

This review summarizes recent advances in understanding the molecular mechanisms of hair follicle formation and discusses potential future clinical applications for treating hair loss and skin tumors, but it reports no new clinical results.

This study identified TGF-β2 as a crucial signal in hair follicle stem cell regeneration, highlighting its role in counteracting BMP signaling to promote tissue regeneration.

This research observed that the skeletal abnormalities in Noggin null mice varied based on genetic background, and identified haploinsufficiency leading to joint fusions, similar to human conditions associated with NOGGIN deficiency.

This study found that overexpression of betacellulin in transgenic mice delayed hair follicle morphogenesis and cycling, increased keratinocyte proliferation, and enhanced wound angiogenesis without affecting wound healing strength.

In this study, researchers found that overexpression of the Hedgehog signaling effector Gli2 in mice led to odontogenic keratocysts development, implicating GLI transcription factors in human keratocyst pathogenesis.

This review explores recent advancements in understanding how various physiological and psychological factors, such as stress and aging, influence epidermal stem cell populations, highlighting their importance in immune-related skin disorders and potential for clinical applications.

This study in mutant mice found that Bmpr2 and Acvr2a are individually redundant, but together essential for normal hair follicle development, with their reduction causing rapid hair cycling and graying.

This study demonstrated that Wnt5a can serve as an orienting signal for mouse skin's planar cell polarity but its overexpression disrupts hair follicle orientation, which can be rescued by modifying Fzd6 levels.

This review discusses the molecular mechanisms driving hair follicle degeneration in skin aging and emphasizes the role of the tissue microenvironment on stem cell function, but reports no new research findings.

In this study, researchers propose that different vertebrate skin appendages, such as hair, feathers, and scales, evolved in parallel from a shared ancestral cell structure associated with teeth, dating back approximately 420 million years ago.

Aging causes hair loss and graying due to stem cell decline and changes in cell behavior and communication.
