Stem cells are primary, unspecialized cells, which are characterized with unlimited self-renewal capacity and [[różnicowanie/en|differentiation]] into specialized descendant progenitor cells forming tissues and organs. The proper function of the body depends on tissue homeostasis, and the maintenance of [[homeostaza/en|homeostasis]] is related with stem cell pool , that balances the number of [[komórki somatyczne/en|somatic cells]] in the body. In each organ of the body thoroughly appears new cells, which maturate and differentiate into organ-specific cells, and after fulfilling their specific biological function they undergo into programmed cell death called [[apoptoza/en|apoptosis]]. Stem cells which reside in a [[nisza komórkowa/en|cellular niche]] of a given organ, receive signals from the environment of the damaged tissue, and starts repair process leading for tissue regeneration.
Stem cells are primary, unspecialized cells, which are characterized with unlimited self-renewal capacity and differentiation into specialized descendant progenitor cells forming tissues and organs. Stem cells exist both in embryos and adult organism. The proper function of the organism depends on tissue homeostasis, and the maintenance of [[homeostaza/en|homeostasis]] is related with stem cell pool, that balances the number of somatic cells in the body. In every organ of the organism systematically appears new cells, which maturate and differentiate into organ-specific cells, and after fulfilling their specific biological function they undergo into programmed cell death called [[apoptoza/en|apoptosis]]. Stem cells, residing in the [[nisza komórek macierzystych/en|stem cell niche]] of a given organ, receive signals from the microenvironment of damaged tissue and initiate the repair process leading to tissue regeneration.
