干細胞的分類Classification of Stem Cells
按照發(fā)生學(xué)來源分類,可分為:Stem cells classification by their genesis:
胚胎干細胞:具有發(fā)育的全能型,可誘導(dǎo)分化為機體中所有種類的細胞,1Embryonic stem cells are totipotent and can give rise to all cell types of the body during development.
成體干細胞:能夠自我更新、并且能夠特化形成特定類型組織或器官2Adult stem cells can renew themselves, and can differentiate to yield the major specialized cell types of the tissue or organ,.
按照分化潛能來分類,可分為:Stem cells classification by their differentiate potential:
全能干細胞,如胚胎干細胞,可以無限增殖并分化成為全身200多種細胞類型,這些分化出的細胞可構(gòu)成人體的各種組織和器官,具有發(fā)育形成完整個體的潛能。1Totipotent stem cells, e.g. embryonic stem cells, can give rise to each of the more than 200 cell types of the body. The differentiated cells make up all the tissues and organs.
多能干細胞,如間充質(zhì)干細胞,具有向多種細胞和組織分化發(fā)育的潛能,但失去了發(fā)育成整個個體的能力。2 Pluripotent stem cells, e.g. mesenchymal stem cells, specify the potential to differentiate into multiple specialized cell types, but can not develop into an organism.
專能干細胞,如表皮干細胞,具有只向一種或密切相關(guān)的兩種類型細胞分化的潛能。3 Unipotent stem cells, e.g. epidermal stem cells, can produce only one cell type or cells of a closely related family.
