This study found that basal cell epithelioma resembles fetal primary epithelial germ based on specific cellular characteristics.

This study identified key cells and pathways needed for the development of touch receptor patterns in mouse skin, notably that certain keratinocytes are crucial for innervation patterns, while Merkel cells and BMP signaling have distinct roles.

This study developed a bioengineering method to reconstruct embryonic dorsal skin from dissociated chick skin cells, allowing feather buds to form and grow in vitro, influenced by epithelial-mesenchymal interactions.

This study found that mesenchymal cells from different organs exhibit substantial heterogeneity, with thymic mesenchymal cells particularly adapted for interacting with epithelial and hematolymphoid cells in high-apoptosis environments.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

This review discusses the interaction between mesenchymal stem cell secretomes and retinal cell secretomes, suggesting their potential in experimental therapies to protect and regenerate retinal tissue.

In a study using a rat model, researchers developed injectable hydrogels from antler reserve mesenchyme which enhanced regenerative healing of full-thickness cutaneous wounds by creating a fetal-like niche that increased stem cell presence and modulated gene expression related to wound healing.

Early-stage skin substitutes improve wound healing and skin structure.

This study examines the structure of the "sinuskissen" in cat hair follicles, revealing it as a loose connective tissue susceptible to changes in aqueous flow, and describes its variable three-dimensional shapes.

This study explains how the development of keratin-associated proteins in embryonic epidermis is crucial for forming protective barriers in vertebrates, enabling them to adapt to terrestrial environments.

This commentary discusses the role of the epidermis in hair follicle induction and reports no new research findings.

Tissue-engineered skin substitutes can model junctional epidermolysis bullosa and may help develop gene therapy.

Mouse Scube3 affects teeth, tongue, vibrissae, and eye development, but not facial structure or limb growth.

This study reported that a Megsin-Cre transgene enables genetic manipulation primarily in skin, forestomach, and esophagus tissues, offering a new tool for studying development and diseases in these areas.

This study reports that KRTAP-like proteins, which resemble keratin-associated proteins found in mammals, are also present in the cornified teeth of various lamprey species, suggesting these proteins may serve similar functions in skin appendages across different vertebrates despite independent evolutionary origins.

In this review, it is discussed how mesenchymal stem cell aggregation plays a crucial role in organ development and has potential applications in organ regeneration through tissue engineering.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

This study found that cell spheres formed from mesenchymal cells in newborn mouse skin showed increased expression of genes associated with hair follicle regeneration, though marker distribution varied and requires further investigation.

In this study, researchers identified Tenascin-C as a marker for touch dome keratinocytes, which maintain themselves and can develop into Merkel cells following injury, showing they share molecular traits with various epidermal keratinocytes.

This review examines the role of stem cells and their niches in continuously growing ectodermal organs like teeth, hair, and claws, providing insights from mouse models without presenting new research findings.

This article reviews confocal microscopy findings in trichoepithelioma and desmoplastic trichoepithelioma, noting similarities with histological features, but it provides no new clinical results.

This study reported the establishment of a chemically defined culture system that supports tooth reconstitution and detailed how co-stimulation of specific signaling pathways can sustain tooth development stages and initiate enamel formation, providing insights into tooth regeneration mechanisms.

This study found that Gelatinase A activity is linked to the absence of type VII collagen during human fetal skin development, indicating its role in remodeling the basement membrane zone.

This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

This study reports a rare case of an epidermal cyst localized in the temporal bone, potentially as a complication of myringoplasty, marking only the fifth such report in English-language literature.

Nephronectin helps attach muscle cells to hair follicles.

This study found that CD90+ cells, resembling mesenchymal stem cells, are abundantly present in the lower part of anagen hair follicles in dogs.

Transamidases are present in the epidermis but their exact role is unclear.

This study concluded that early-stage tissue-engineered skin substitutes, developed using skin progenitor cells, had a better graft efficiency and supported hair follicle formation, which may improve wound healing outcomes.
