This review discusses melanocyte stem cells in hair follicles and their potential role in cell-based therapy for vitiligo, reporting no new experimental results.

This article suggests that imaging abnormalities in intestinal stem cell compartments could potentially be incorporated into colorectal cancer screening, but provides no new clinical results.

This review discusses the therapeutic potential and challenges of using extracellular vesicles derived from mesenchymal stem cells, concluding that they may have a comparable therapeutic potential to the original cells despite current challenges in their application and production.

This study found that a catalytically active version of Vav2 significantly altered gene expression patterns in hair follicle stem cells in mice, with these changes varying over the animals' lifespans.

This study found that isolated hair follicle outer root sheaths from mice can regenerate new dermal papillary structures in vitro, with stem cells and neutrophils playing key roles in the regeneration process.

This study reports that hair regeneration in live mice involves spatially regulated stem cell divisions and requires mesenchymal interactions, observed in real-time using a novel non-invasive imaging method.

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.

In this study, dermal papilla cells from rat vibrissae showed potential for treating CNS injuries by secreting neurotrophic factors and promoting neuronal differentiation more effectively than bone marrow mesenchymal stem cells.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This study reviews the regenerative potential and clinical applications of exosomes derived from mesenchymal stem cells in conditions like COVID-19, alopecia, skin aging, and osteoarthritis, highlighting their role as a promising tool in regenerative medicine.
