This review discusses advanced techniques for investigating stem cell fate at the single-cell level, including lineage tracing, time-lapse imaging, and molecular profiling, but reports no new research results.

This study found that PDGFA is critical for the proliferation and maintenance of adipocyte stem cells in skin but not other white adipose tissues, highlighting unique regulatory mechanisms in different tissue depots.

This review highlights various methods of stem cell communication that reflect the unique organization and function of different tissues and reports no new results.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

This study established a new cell line from human hair follicle stem cells that maintains stem cell properties and differentiation capabilities, providing a useful in vitro model for stem cell research.

This study found that RhoA influences embryonic stem cell proliferation through the PKN1-cyclin D1 pathway in vitro, suggesting RhoA as a potential target for wound healing therapies.

This study found that telomere shortening disrupts BMP/pSmad/P63 signaling, leading to skin atrophy via Follistatin up-regulation, and suggests potential therapeutic targets.

This review discusses how recent advances in live imaging have revealed the dynamic and adaptable nature of stem cells during various biological processes, and reports no clinical results.

In this study, researchers found that CD4 is expressed on murine K5⁺ keratinocytes, and its expression is crucial for maintaining epidermal stem cell balance and wound repair capacity, particularly during aging.

This study found that in hairpoor mice, disruptions in hair follicle stem cell quiescence and signaling pathways lead to disturbed hair cycles, which may help explain alopecia development in Marie-Unna Hypotrichosis patients.

This study suggests that with aging, mouse corneal renewal increasingly relies on Lrig1+ stem cells as CD44 expression and Wnt activity decline.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study found that glycolytic metabolism and lactate production are crucial for hair follicle stem cell activation, and manipulating these processes can stimulate the hair cycle.

This review discusses the roles of interferon-γ and PPAR-γ-mediated signalling in scarring alopecia, suggesting these pathways as potential therapeutic targets, but it reports no new empirical results.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

In this study, researchers found that deleting Caspase-9 in hair follicle stem cells delayed apoptosis, leading to accelerated wound repair and new hair follicle regeneration by maintaining apoptotic cells as signaling centers.

This study suggests that mesenchymal stem cell therapy may improve cell viability and regulate key signaling pathways in vitro for treating alopecia areata.

This study found that activating CB1 receptor signaling in human hair follicles increased stem cell proliferation while reducing differentiated cell survival, suggesting CB1's role as a survival stimulus for epithelial stem cells.

This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

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