چکیده انگلیسی
Stem cells are defined by their self-renewing capacity and the ability to differentiate into one or more cell types. Stem cells can be divided, depending on their origin, into embryonic or adult. Embryonic stem cells derive from early stage embryos and can give rise to cells from all three germ layers. Adult stem cells, first identified in hematopoietic tissue, reside in a variety of adult tissues. Under normal physiologic conditions, adult stem cells are capable of differentiating into the limited cell types that comprise the particular tissue or organ. Adult stem cells are responsible for tissue renewal and exhaustion of their replicative capacity may contribute to tissue aging. Loss of unlimited proliferative capacity in some of the adult stem cells and/or their progenitors may have involved the evolutionary trade-off: senescence prevents cancer but may promote aging. Embryonic stem cells exhibit unlimited self-renewal capacity due to the expression of telomerase. Although they possess some cancer cell characteristics, embryonic stem cells exhibit a remarkable resistance to genomic instability and malignant transformation. Understanding the tumor suppressive mechanisms employed by embryonic stem cells may contribute to the development of novel cancer treatments and safe cell-based therapies for age-related diseases.
