This review discusses how certain adult stem cells can produce factors that support the maintenance of other stem cell populations within shared niches, and it reports no new experimental results.

This study found that intradermal injections of plant-derived exosomes in adults with early-stage alopecia increased stem cell activity, activated Wnt signaling pathways, and reduced certain immune cell populations, providing insights into their role in hair follicle regeneration and suggesting potential for hair restoration therapy.

This study found that adult rat olfactory mucosa can generate neurospheres capable of self-renewal and multipotency when cultured under specific conditions.

This study identified ectomesenchyme as a major source of epidermal stem cells in mouse skin, with ectomesenchymal keratinocytes occupying a significant portion of the epidermal stem cell-enriched population.

This study introduces a method for long-term expansion of adult mouse epidermal stem cells in vitro using an organoid culture system that maintains the basal-apical organization.

Researchers created long-lasting, diverse skin organoids from mouse hair follicle stem cells, useful for studying skin.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.

This dissertation reports that Lrig1 and Lgr6 mark distinct stem cell populations in mouse hair follicles, playing roles in tissue regeneration and tumor development, with Lgr6 regulating Wnt signaling and restraining epidermal lineage commitment.

This research details a robust method for isolating hair follicle stem cells and epidermal keratinocytes from mouse hair follicles using fluorescence activated cell-sorting technology.

This review discusses the embryonic origins and characteristics of various stem cell populations in the skin, but it provides no new experimental results.

This review discusses stem cell behavior, highlighting their plasticity in tissue repair and the impact of somatic mutations on clonal expansion in early cancer, but reports no new experimental results.

This study found that the creation of hair follicle lumens in mice is driven by the outward migration of keratin 79-positive cells, suggesting a novel mechanism for generating hollow cores in hair follicles.

This research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.

This review discusses the potential of dental stem cells from deciduous and permanent teeth for tissue regeneration and reports no new experimental results.

This study found that the dysfunction of hair follicle dermal stem cells with age contributes to hair follicle aging and hair loss in mice.

This study found that depleting fibroblasts in the skin does not affect the proliferative capacity of epidermal stem cells at various ages, suggesting robust compensatory mechanisms maintain skin functionality despite these cellular changes.

This review discusses the progress in identifying stem cells responsible for tissue regeneration and highlights technological advances in tracking their behavior, but reports no new clinical results.

The researchers identified differences in gene expression between fetal and adult dermal papilla cells that could explain fetal cells' ability to regenerate hair follicles, while adult cells lack this capacity.

Adult hair follicle cells can create new hair follicles from corneal cells with the right support.

This review indicates that most studies reported positive effects of platelet-rich plasma injections for treating androgenic alopecia, with no major side effects, suggesting it may be a safe alternative to Minoxidil and Finasteride.
