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 anthralin and mechlorethamine were the most effective therapies among those tested in AA-affected rodent models, providing a basis for further analysis of their mechanisms in Alopecia Areata.

This study explored the role of Twist2 in fetal wound healing in embryonic mice, observing that its expression was vital for scarless regeneration and normal hair follicle formation; Twist2 knockdown led to visible scars and defective follicle formation.

In this study, researchers found that the protein Twist2 plays a crucial role in scarless wound healing in early embryonic mouse skins, with its knockdown leading to visible scarring and defective hair follicle formation, suggesting potential therapeutic targets for reducing scars and promoting regeneration.

This review summarizes current research on molecular pathways, such as Wnt and Notch, that regulate feather follicle development in yellow-feathered broilers, highlighting their potential impact on poultry carcass quality and suggesting areas for future study.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

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

This review discusses molecular signaling pathways and nutritional factors influencing feather growth and regeneration in poultry and offers no new results; the authors suggest these insights may guide strategies for producing superior plumage.

Retinoic acid receptors are important for hair follicle development.

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.

This review discusses the role of dermal papilla cells in hair follicle formation and their potential use in cell therapy for hair loss, but reports no new research findings.

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 the origins, differentiation, and function of dermal fibroblasts in skin development and healing, reporting no new clinical results.

This study found that desmocollin 1 is crucial for strong adhesion and barrier maintenance in the mouse epidermis, with its absence leading to skin and hair issues resembling chronic dermatitis.

In this study, Dsc 1 was highly expressed in certain layers of fetal epidermis and hair follicle but not in basal cells or oral mucosa, indicating its potential role in maintaining epithelial integrity.

This study reports on an ongoing Phase I/IIa clinical trial of ex vivo gene therapy for treating severe Recessive Dystrophic Epidermolysis Bullosa, involving six adult participants with COL7A1 mutations resulting in deficient type VII collagen production.

In this study, targeted deletion of the stearoyl-CoA desaturase 1 gene in mice disrupted the epidermal lipid barrier, leading to increased water loss, impaired thermoregulation, and metabolic issues.

This study found that conditional deletion of CD271 in mouse epidermis led to significant disorganization and increased thickness, suggesting CD271's crucial role in regulating skin differentiation and structure.

This study found that deleting all three Desmoglein 1 genes in mice led to impaired skin barrier function, disorganized epidermis, and postnatal lethality, highlighting Dsg1's essential role in epidermal development and maintenance.

A 4kb fragment of the desmocollin 3 promoter targets gene expression to specific skin and hair follicle areas.

This study developed new immortalized keratinocyte cell lines lacking COL7A1 using CRISPR/Cas9 technology, providing a valuable model to explore the biology and treatment options for recessive dystrophic epidermolysis bullosa.

This study reported the creation of isogenic immortalized COL7A1-deficient keratinocyte lines, providing a model for researching Recessive Dystrophic Epidermolysis Bullosa biology and potential therapies.

CRISPR/Cas9 and prime editing can potentially fix skin disorder genes safely and effectively.

In this study, KC-AD-MSCs were found to increase COL7 deposition and anchoring fibril formation at the dermal-epidermal junction in a RDEB mouse model, suggesting potential for improving skin integrity in recessive dystrophic epidermolysis bullosa patients.

In their mouse study, Oda et al. found that removing the MED1 gene in the skin led to hair loss and changes in epidermal cell differentiation, indicating MED1's significant role in these processes.

This study demonstrated that gene-corrected 3D skin constructs from RDEB patient-derived iPSCs, grafted onto immunocompetent mice, showed normal collagen VII expression after two months.

In this study, researchers found that skin pigmentation alterations in a mouse model of Carney complex may be caused by specific dermal fibroblasts promoting melanogenic signaling.
