This study found that human fetal CD133+ progenitor cells and their conditioned medium accelerated wound healing and promoted angiogenesis in a mouse model of ischemic diabetic ulcers through paracrine mechanisms involving Wnt signaling.

This study demonstrated that β-catenin signaling in CD133+ dermal papilla cells enhances postnatal hair growth by accelerating the proliferation and differentiation of keratinocytes in the murine hair cycle.

The study found that up-regulating β-catenin signaling in CD 133-positive dermal papilla cells enhanced their ability to promote hair follicle regeneration both in vitro and in vivo.

This study found that Wnt ligands from CD133-positive dermal papilla cells are essential for maintaining hair growth by supporting cell signaling between different hair follicle structures.

This article discusses the potential therapeutic use of CD133+ progenitor cells and their conditioned medium for diabetic ischemic ulcers, reporting no new results.

This study found that CD133-positive dermal papilla cells significantly enhanced hair growth in mice compared to CD133-negative cells, suggesting their potential for improving human hair follicle engineering.

This study suggests that the presence and arrangement of plasmacytoid dendritic cells can help distinguish chronic cutaneous lupus erythematosus from other types of scarring alopecia.

This letter discusses three plasmacytoid dendritic cell-related parameters that may help differentiate lupus alopecia from lichen planopilaris, but it reports no new study results.

This study demonstrates that Sox2-positive dermal papilla cells specify particular hair follicle types by showing heterogeneity in gene expression and pathway activation in these cells.

This study reported that a three-dimensional hydrogel culture system supports the growth and maintenance of distinct dermal papilla cell types, crucial for skin reconstitution assays in neonatal mice.

This study found that the absence of Ctip2 in epidermal keratinocytes led to impaired wound healing in mice, affecting cell migration, proliferation, and hair follicle stem cell maintenance.

This study demonstrated that combining AMD3100 with low-dose tacrolimus in a stem cell mobilization approach significantly reduced wound healing time and improved scar and hair follicle regeneration in full-thickness skin wounds.

This study suggests that human mesenchymal stem cells have the potential to differentiate into dermal papilla cells both in vitro and in vivo.

This study explored the dermal stem cell niche of equine hair follicles, revealing typical fibroblast morphology and confirming the expression of standard stem cell markers comparable to other species.

This study discusses treatment approaches for refractory Asherman syndrome, highlighting the potential role of CD133+ bone marrow-derived stem cells in conjunction with hysteroscopy for endometrial regeneration and improved pregnancy outcomes.

This study found that combining AMD-3100 with FK506 in subimmunosuppressive doses enhanced stem cell release from bone marrow, resulting in 25% faster epithelialization in excisional wounds in rats and mice.

This study concluded that placental mesenchymal stem cells from aborted fetal tissue may serve as an in vitro model for studying spontaneous abortion mechanisms and potential regenerative therapies due to their abnormal gene expression and differentiation capabilities.

In this study, researchers observed that using microtube-based forced aggregation, human hair follicle dermal papilla cells formed stable, compact spheroids at higher cell densities, showing enhanced expression of specific markers compared to 2D culture.

This study found that metformin may promote hair follicle regeneration by enhancing dermal cell activity in an in vitro mouse model, suggesting potential for treating pattern hair loss.

The study observed that cell spheres formed from mesenchymal cells of newborn mice skin exhibited upregulation of markers linked to hair follicle regeneration, suggesting a potential hibernation-like state for maintaining viability.

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.

This study found that transplanting cell aggregates from mouse skin and lung mesenchymal cells can regenerate hair follicles in immunodeficient mice with skin wounds.

This study observed that cell aggregates derived from mouse skin and lung tissues may aid in hair follicle regeneration when transplanted into skin defects of immunodeficient mice.

This study found that skin exposure to toluene diisocyanate in mice creates immune-recognition reservoirs in the skin's stratum corneum and hair follicles, potentially leading to sensitization and allergic reactions.

This review discusses the classification and diagnosis of primary scalp alopecia, focusing on scarring and non-scarring types, and reports no new clinical results; it emphasizes simplified diagnostic pathways and tissue processing techniques.

This study found that antroquinonol inhibited CD8+ T cell proliferation and reduced proinflammatory cytokine secretion in vitro, while also ameliorating H2O2-induced depigmentation and resisting reductions in hair follicle length, skin thickness, and tyrosinase expression in mice.

T cells affect skin cell genes in inflammatory diseases, and therapy can normalize these changes.

Chronic refractory alopecia areata has more skin-resident memory T cells, and JAK inhibitors may help reduce them.

This clinical case report identifies xanthomatous hypophysitis in a male patient, highlighting the mismatch between clinical symptoms and MRI findings, which led to a pituitary biopsy and accurate diagnosis instead of unnecessary surgery.
