This study confirmed the presence of specific stem cell populations in SKH1 hairless mice skin, including CD34+/α6-integrin+ cells, which are important for investigating ultraviolet radiation-induced carcinogenesis.

This review discusses the niches supporting adult stem cells in various organisms, including well-studied germline niches and the less understood mammalian niches, but it reports no new research findings.

This study found that human hair follicle stem cells formed more colonies and adhered more rapidly, while transit-amplifying cells showed significantly greater mobility.

In this study, intradermal injection of GCSF-mobilized peripheral blood stem cells from young pigs rejuvenated skin in aged pigs by increasing collagen, elastin, and cell renewal rates.

This study identified a proliferative intermediate transcriptional state associated with the transition from secondary hair germ cells to lower hair follicle-associated cells during early hair follicle regeneration in mice.

This review explores current knowledge on fibroblast lineage specification and its impact on scar-free wound healing, noting that early fetal skin fibroblasts support regeneration, while later developmental shifts lead to fibrosis, highlighting potential strategies to reprogram adult fibroblasts for regenerative repair.

Stress can cause hair to turn gray by depleting stem cells.

This study found that coculturing human hair follicle keratinocyte stem cells with dermal papilla cells increased expression of the hair-specific keratin 6hf gene, which requires β-catenin/lef-1 signaling for hair differentiation.

This study found that 808 nm laser photobiomodulation altered mitochondrial respiration and enhanced osteogenic protein expression in human dental pulp stem cells, with the effects being dose-specific and more pronounced at 15 J/cm².

This review discusses recent advances in understanding acne pathobiology, highlighting the potential for developing new customized therapies, but it reports no new clinical findings.

This study characterizes gene expression patterns in embryonic hair follicle progenitors and their niche, identifying signaling pathways like axon guidance that may drive cellular rearrangements for hair follicle formation.

Alopecia areata is caused by an immune response, and targeting immune cells might help treat it.

This study developed PiSCES biosignatures that distinguished alopecia areata patients from controls, revealing enhanced basal TCR signaling and a potential disease-specific signaling network signature.

This study identified key mRNAs and lncRNAs, along with related pathways, that play potentially important roles in hair follicle development and cycling in cashmere goats.

This study found significant gene expression abnormalities in hair follicles affected by alopecia areata, suggesting persistent changes that may predispose to future relapses even after hair regrowth.

This review explores how epidermal stem cells contribute to the development and maintenance of various skin structures, and highlights specific markers and proteins associated with these cells, but reports no new clinical results.

This study found that specific gene upregulations and mutations in hidradenitis suppurativa skin support the role of inflammation, altered epithelial differentiation, and metabolism dysregulation in the disease's pathogenesis.

This review summarizes the role of non-coding RNAs in hair follicle regeneration and highlights potential therapeutic strategies, though it reports no new experimental results.

This study suggests that distinct chromatin topologies allow different lineage-specific enhancers to regulate Hoxd genes in mouse vibrissae and chicken feather primordia, while conserved regulatory elements maintain transcriptional robustness in the embryonic trunk across species.
