This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study found that the postnatal thymus contains a population of mesenchymal stem cells that may help maintain functional thymic microenvironments.

This study revealed that telocytes are crucial Wnt-producing niche cells necessary for hair follicle regeneration in mice, with their removal or the absence of their Wnt signals halting the regenerative process.

This study found that ILC1-like cells can induce alopecia areata in healthy human hair follicles, challenging the traditional belief that the disease is primarily driven by CD8+ T cells.

This review discusses techniques for analyzing the cell cycle, highlighting emerging tools for measuring cell cycle speed at single-cell resolution in live animals, and reports no new results.

In this study, researchers identified hair follicle stem cells in the bulge region of canine hair follicles, suggesting potential applications for future translational research.

This article discusses the structure and function of the skin's layers, cell types, and tumor development, without reporting new clinical findings, and highlights the growing incidence of skin cancer.

This review summarizes recent insights into corneal limbal stem cell differentiation and the potential role of progenitor-like cells, but reports no new experimental results.

This article reviews recent research on adult epidermal stem cells, discussing their properties and potential for reprogramming into patient-specific therapies, and emphasizes the need for further development while minimizing cancer risk.

Krox20 is important for cell differentiation in the brain and hair follicles.

This study suggests that five small molecules can induce hair follicle neural crest stem cells to differentiate toward motor neuron progenitor cells with a unipotent differentiation potential.

This study describes a method for isolating stem cells and keratinocytes from mouse hair follicles using FACS technology, facilitating the study of stem cell biology.

In this study, researchers observed distinct aging signatures in mouse keratinocytes, with increased expression in older mice, and noted relevant pathway changes that were also evident in human skin, suggesting potential insights into intrinsic skin aging.

This review examines the emergence of new adult stem cell sources with potential for bone tissue engineering and discusses their advantages over traditional sources.

This study found that bone marrow-derived epithelial cells were abundantly recruited to some skin tumors in mice, indicating a systemic contribution to cutaneous neoplasms.

This study found that dedifferentiated corneal epithelial cells can revert to a stem-cell-like state, aiding tissue homeostasis and repair, with this plasticity limited to the epithelial lineage and enhanced by niche-derived cytokines.

This study reported the successful isolation of epithelial stem cells from mouse embryonic skin using a simple culture method, with the cells showing the potential to differentiate into multiple cell types.

This study found that keratin 19 and nuclear galectin-1 binding can transiently express in interfollicular epidermal cells after adhesion, suggesting keratin 19 should not be solely used as a stem cell activity marker.

This review discusses how epidermal Langerhan's cells and dermal cells may influence keratinocyte environments, potentially aiding in the formation of stem cell niches and cellular variety in the basal layer, without providing novel results.
