Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study identified key components of melanocyte stem cell niches that maintain stem cells in a dormant state and established a culture system that potentially replicates some aspects of in vivo stem cell activity.

This study found that neural crest-derived hair follicle cells in mice can differentiate into osteoblast-like cells, suggesting a potential application for bone regenerative therapies.

This study found that cutaneous stem cells in the basal layer of fetal human skin contribute to the development of the epidermis and hair follicles, with specific marker expressions during different stages of skin development.

This study found that KLF4 expression in mouse hair follicle stem cells is important for effective cutaneous wound healing, with its knockdown leading to reduced stem cell populations and delayed healing.

In this study, nondermal-derived CD34+ cells from adult peripheral blood were found to enhance wound healing and contribute to hair follicle neogenesis and skin regeneration.

This research found that Foxc1 is critical for maintaining quiescence in activated hair follicle stem cells and that the cancer cell-of-origin influences tumor heterogeneity in mouse skin squamous cell carcinoma.

In this study, the Foxn1(-/-) nude phenotype was associated with an altered regulation of epithelial progeny in skin, offering a valuable model for investigating stem cell niche maintenance and regulation.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This review discusses strategies for identifying and characterizing adult stem cells in mice and highlights their potential and limitations, but reports no new experimental results.

This study found that cultured hair follicle dermal cells support maintenance and potentially aid in the clinical application of pluripotent and haematopoietic stem cells.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This review discusses current knowledge of keratinocyte stem cell dynamics, including their regenerative roles and potential applications beyond wound healing, but presents no new clinical findings.

In this study using live mice, researchers observed that during hair follicle regression, apoptosis in basal cells may propagate by triggering neighboring cells, potentially regulated by a gradient of pro-survival signals from stem cells, and proposed a testable mechanism to further explore this process.

This study identified Lgr5 and Lgr6 as receptors expressed by small populations of stem cells in various adult organs, with Lgr5+ve cells forming long-lived organoids in certain mouse models.

This study found that BrdU labeling in Inner Mongolia cashmere goats revealed the presence and localization of stem cells in primary and secondary hair follicles and the epidermis, with signals diminishing after 10 weeks.

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

In this study, nestin-expressing cells in the hair follicle bulge, marked by GFP in transgenic mice, were identified as progenitors of the hair follicle outer-root sheath.

Human hair follicles can provide stem cells for regenerative medicine.

This study found that OCT4-overexpressing human hair follicle mesenchymal stem cells show promise for artificial hematopoiesis by enhancing self-renewal through cytoskeletal remodeling and the beta-catenin-dependent adherens junction pathway.

This review examines regulatory mechanisms of quiescent stem cells in tissue homeostasis, drawing on observations from the intestine and other self-renewing tissues, without presenting new data.

This study found that cardiac fibroblasts significantly enhance the maturation of neonatal mouse and human embryonic stem cell-derived cardiomyocytes, suggesting a pivotal role in postnatal heart development and disease.

This study found that nestin-negative hair follicle stem cells can differentiate into neural stem cell-like cells, but not mature neurons, through a multi-step neuro-induction process.

This review discusses the role of cellular heterogeneity and interaction in the skin's ability to maintain homeostasis despite cancer-causing mutations, noting the potential for these cells to also drive tumor formation, but reports no new clinical results.

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.

The researchers observed that vitiligo-affected skin shows a selective depletion of NTRK2+ melanocyte subpopulations with progenitor features, which may contribute to poor treatment responses.

This article reviews the evolving understanding of hematopoietic stem cells, including their heterogeneity and the role of cytokines in lineage determination, and reports no new results.

Bulge progenitor cells show promise for regenerating hair follicles and increasing hair density.

Basal cell carcinoma shows keratin patterns similar to undifferentiated hair follicle cells.

This meeting in Heidelberg highlighted diverse contributions on stem cell research, including pre-clinical and clinical applications, but reported no new experimental results.
