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

This study found that combining a human acellular amniotic membrane with iPSC-derived epithelial stem cells effectively repaired skin defects and promoted hair follicle formation in nude mice.

In this study, cultured skin equivalents with ovine hair follicle dermal papillae grafted onto nude mice developed follicle-like structures, suggesting a potential model for studying hair follicle development.

This study demonstrates the use of microscopy-guided laser ablation to create a highly structured 3D hydrogel-based organotypic skin model with folliculoid structures, potentially useful for studying hair follicle development or bioactive substance screening.

This study suggests that exogenous retinoic acid can alter the morphogenesis pathway of developing skin appendages when applied during the placodal stage, leading to changes like feather formation in atypical regions of chick embryos.

This study found that gelatin sponges used as scaffolds in rats with deep wounds and periosteal defects enabled regeneration of diverse tissue types, including periosteum, skin, and appendages, highlighting the role of vascular niche formation.

This study reports that the maintenance and morphogenesis of skin appendages rely on both the dose and duration of ectodysplasin signaling.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

This study identified a new S100 fused-type protein, scaffoldin, in reptiles and birds and suggests that SFTP-positive epithelia serve as scaffolds for the growth of various skin appendages, indicating a common evolutionary origin.

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

This review discusses human hair follicle development and highlights the potential of creating human in vitro models and skin substitutes with hair follicles, reporting no new clinical results.

This review discusses the regenerative processes of deer antlers compared to other vertebrates and reports no new experimental findings, suggesting insights for regenerative medicine and cancer biology.

This study found that rete ridge morphogenesis in mammalian skin is directed by a BMP-dependent developmental program, which is evolutionarily distinct from other known pathways controlling the development of hair follicles, sweat glands, and fingerprint ridges.

This study found that the absence of Sostdc1 in mice alters mammary gland and hair follicle development, particularly by increasing vibrissae numbers and causing unusual nipple-like structures.

This review discusses the regenerative processes of lizard tails, particularly focusing on the diversity in blastema development across different species, and reports no new findings.

This study reveals that transglutaminase activity is widespread in integumentary structures of mammals and birds, suggesting it plays a significant role in the cornification of hard skin appendages like nails and feathers.

Miliacin may help prevent hair loss and improve hair growth in mice with a condition similar to human baldness.

This study found that monoclonal antibodies identified distinct staining patterns in benign and malignant skin appendage tumors, highlighting their potential as markers for analyzing skin tumors.

This research re-analyzed single-cell gene expression data from a mouse model, confirming that certain genes involved in the EDA-EDAR and WNT pathways are crucial for skin appendage development, suggesting that their restoration may mitigate the effects of hypohidrotic ectodermal dysplasia in children.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

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 paper proposes that GDNF signaling may enhance skin regeneration and hair follicle formation by influencing dermal fibroblast differentiation, particularly following injury.

This article reviews the complex process of wound repair, emphasizing recent microarray studies and proteomic analyses, but reports no new clinical results.

This review found that 3D bioprinting significantly advances skin tissue engineering by enabling the creation of complex, patient-specific skin structures, though technological and regulatory challenges persist, particularly in areas like scalability and physiological mimicry.

This study found that ARHGEF3 is crucial for hair follicle development in mice, as its absence leads to defects in placode compaction and impaired follicle downgrowth, highlighting its role in regulating cell shape rearrangements during embryogenesis.

This research studied the effect of local testosterone propionate applications on rabbit epidermal mitotic activity but reports no new results.

The study concluded that local administration of in-vitro-expanded bone marrow-derived mesenchymal stem cells accelerates and promotes healing in full-thickness excisional wounds in adult male albino rats.

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 study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This study found that Diabetex significantly improved wound healing and reduced fasting blood sugar in diabetic rats, showing potential as a safe and economic treatment strategy for diabetic-resistant wounds.
