In this study, transplantation of rat hair follicle stem cells significantly improved sciatic nerve regeneration and muscle function in nerve-injured rats.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This review suggests that although hydrolyzed collagen peptides with certain supplements may improve skin elasticity and joint function, evidence for collagen's anti-aging and regenerative benefits remains inconsistent.

In this study, researchers used NIR-II fluorescence imaging to track the survival and migration of EPI-NCSCs in rat models, finding that these stem cells aided in repairing facial nerve defects when applied via acellular nerve allografts.

This study found that methylene blue staining may reveal anatomical details of intraepidermal nerve fibre endings in the rat mystacial pad with greater clarity than the zinc iodide-osmium tetroxide technique.

This study observed that methylene blue staining and zinc iodide-osmium tetroxide techniques effectively revealed anatomical details of intraepidermal nerve fibre endings in the rat's mystacial pad, suggesting their potential role in mechanoreception.

This study developed a tissue-engineered model of innervated skin, allowing for examination of how epidermis and capillaries affect nerve growth and offering a tool for further research on skin-related processes.

In this review, researchers highlighted the pivotal role of the epicardium in heart regeneration and repair, particularly through its cellular programs and signaling during myocardial infarction, though they noted challenges in replicating these processes in nonregenerative mammals, suggesting pathways for innovative cardiovascular therapies.

This review outlines the structure and functions of the skin, emphasizing its role as a physical and immune barrier, its moisture regulation, the influence of its microbiome, and the supportive functions of its layers and adnexa.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.

In this study, the duration of epinephrine-induced vasoconstriction in scalp tissue increased with concentration and was longer at the frontotemporal junction compared to the midfrontal area, significantly so at the highest concentration used.

Healthy skin prevents water loss and protects against threats.

The cuneate nucleus has two main neuron types: relay neurons and interneurons.

This study found that the occipital scalp had significantly higher epidermal nerve fiber density than the frontoparietal scalp, which may explain increased sensitivity in some patients.

This study observed that the mechanical connection between hair follicles and connective tissue in human fetal scalp skin is weaker than in the corresponding skin components, reflecting dynamic processes in hair growth.

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 histological study of Millivora Capenesis skin describes the composition of the dermis, featuring distinct papillary and reticular layers with associated structures like hair follicles, glands, and corpuscles.

In this study, researchers observed that P2X3-immunoreactive fibers extensively innervate the epidermis of rats, suggesting a primary role in detecting noxious stimuli in cutaneous tissue.

This rat study found that a PLGA conduit filled with neural crest stem cells derived from hair follicles showed promising results in repairing peripheral nerve injuries, partially restoring sensory function and improving nerve structure.

This study found that the vermilion border and mucosa of the monkey lip have a dense sensory innervation, which correlates with their known tactile sensitivity.

This study found that epidermal stem cells in nonglabrous skin are connected to the distal end of the arrector pili muscle, which may play a role in epidermal renewal and wound healing.

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 reviews the embryological origins, anatomical and histological structure, and key functions of the skin, emphasizing its protective, sensory, and regulatory roles, as well as the social and psychological impacts of post-lesion changes.

This article discusses the role of epimorphin as a key morphoregulator for various epithelial cells in tubulogenesis and reports no experimental results on its signaling pathways.

This study describes the structural composition of the skin's dermis in experimental animals, highlighting the arrangement of collagen, elastic, and reticular fibers as well as associated glands and muscles.

In this study, upper-bulge epidermal stem cells in mouse hair follicles were shown to play a role in forming tactile sensory units by creating an extracellular matrix that supports nerve interactions.

This study found that upper-bulge epidermal stem cells in mouse hair follicles are specialized for nerve interactions, crucial for forming tactile sensory units, and influence touch responses via EGFL6 and αv integrin pathways.

This study found that sensory and sympathetic innervation in the mystacial pads of mice is governed by a balance of neurotrophin signaling, highlighting the roles of NGF/trkA and NT-3/trkC pathways.
