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 animal study found that high dietary vitamin A levels altered hair cycling by affecting WNT and BMP signaling pathways in mice, which could be reversed by reducing vitamin A intake.

This study reveals that the microRNA-200 family, highly enriched in hair matrix progenitors, restricts sebaceous gland development by inhibiting the SOX9-dependent lipogenic program, highlighting its specific role in epithelial plasticity within hair follicles.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

This study describes how feather pigmentation in birds is regulated by melanocyte distribution, differentiation, and patterned agouti expression, contributing to diverse and adaptive color patterns.

Skin changes throughout life, from development before birth to aging effects like wrinkles, influenced by both genetics and environment.

This study suggests that while cellular senescence impairs epidermal stem cells in aging, it also serves an essential role during embryonic development, highlighting its dual functional nature.

This study validated a protocol for inducing surface ectoderm differentiation from human induced pluripotent stem cells and highlighted the role of TGFβ signaling pathways in this process.

This study found that epimorphin is closely linked to developing hair follicles in human fetuses, suggesting it plays a significant role in hair follicle morphogenesis.

This study found that cells from the upper hair follicle exhibited more active growth compared to other segments in vitro, suggesting their potential as a source of hair follicle stem cells.

This study found that regulatory T cells accumulate in hair follicle epithelium via the Cxcr4-Cxcl12 axis, partially influenced by glucocorticoid receptor signaling, promoting hair regeneration; similar mechanisms were observed in human and murine skin.

This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This study found that OCT4B1 isoform expression was elevated in tissue and blood samples from patients with inflammatory bowel disease, suggesting a potential role in tissue repair.

This study found that nestin-expressing hair follicle-derived cells express higher levels of certain neurotrophic factors and neural markers, indicating potential for neuroregenerative therapy applications.

MRI helps distinguish between pituitary adenomas and craniopharyngiomas, guides treatment for pediatric CNS tumors, and assesses rhinocerebral mucormycosis with a high mortality rate in transplanted patients.

This study categorizes the human fetal vaginal epithelium into four areas with distinct transcriptomic profiles, aiding potential advancements in vaginal reconstruction and drug delivery.
