Runx1 modulates adult hair follicle stem cell emergence and maintenance from distinct embryonic skin compartments
Runx1 controls hematopoietic stem cell emergence and hair follicle stem cell (HFSC) activation and proliferation in adult skin. Here we use lineage tracing and mouse genetic manipulation to address the role of Runx1 in the embryonic development of HFSCs. We find Runx1 is expressed in distinct classes of embryonic skin precursors for short-term HF progenitors, adult HFSCs, and mesenchymal progen...
متن کاملRunx1 modulates developmental, but not injury-driven, hair follicle stem cell activation.
Aml1/Runx1 controls developmental aspects of several tissues, is a master regulator of blood stem cells, and plays a role in leukemia. However, it is unclear whether it functions in tissue stem cells other than blood. Here, we have investigated the role of Runx1 in mouse hair follicle stem cells by conditional ablation in epithelial cells. Runx1 disruption affects hair follicle stem cell activa...
متن کاملRunx1 and p21 synergistically limit the extent of hair follicle stem cell quiescence in vivo.
Mechanisms of tissue stem cell (SC) quiescence control are important for normal homeostasis and for preventing cancer. Cyclin-dependent kinase inhibitors (CDKis) are known inhibitors of cell cycle progression. We document CDKis expression in vivo during hair follicle stem cell (HFSC) homeostasis and find p21 (cyclin-dependent kinase inhibitor 1a, Cdkn1a), p57, and p15 up-regulated at quiescence...
متن کاملMelanocyte Stem Cell Maintenance and Hair Graying
Hair graying is an obvious sign of human aging, yet little was known about its causes. Two recent papers provide compelling evidence that hair graying is due to incomplete melanocyte stem cell maintenance and identify Pax3 and Mitf as key molecules that help regulate the balance between melanocyte stem cell maintenance and differentiation.
متن کاملسلولهای بنیادی bulge فولیکول مو: منبعی جدید برای بازسازی پوست
Emergence and spread of various diseases in the past century have been associated with many problems for the health care providers. Now a days, with advancement of technology, new methods such as cell therapy, are available, efficient and successful in some clinical areas. To use any cell, it is necessary to identify its source, so herein, we reviewed the literature of a new source of adult ste...
