雖然ATCC細(xì)胞于在正常發(fā)育過(guò)程中產(chǎn)生細(xì)胞,但來(lái)自幾個(gè)方面的證據(jù)都表明,它們?cè)谶m當(dāng)條件下可成為多能細(xì)胞。現(xiàn)在,這些條件已被發(fā)現(xiàn)。從來(lái)自成人未成熟人細(xì)胞開(kāi)始,Conrad等人確定了可像人胚胎干細(xì)胞一樣被操縱和分化的細(xì)胞系。這些細(xì)胞可被穩(wěn)定地分化成為分泌胰島素的細(xì)胞或肌性細(xì)胞系、成骨細(xì)胞系和與神經(jīng)細(xì)胞相似的細(xì)胞系。當(dāng)在皮下移植時(shí),這些細(xì)胞會(huì)在小鼠身上形成畸胎瘤,這是它們具有多能性的進(jìn)一步證據(jù),也反映了這些細(xì)胞在再生治療中所具有的潛力。

Abstract
Human primordial germ cells and mouse neonatal and adult germline stem cells are pluripotent and show similar properties to embryonic stem cells. Here we report the successful establishment of human adult germline stem cells derived from spermatogonial cells of adult human testis. Cellular and molecular characterization of these cells revealed many similarities to human embryonic stem cells, and the germline stem cells produced teratomas after transplantation into immunodeficient mice. The human adult germline stem cells differentiated into various types of somatic cells of all three germ layers when grown under conditions used to induce the differentiation of human embryonic stem cells. We conclude that the generation of human adult germline stem cells from testicular biopsies may provide simple and non-controversial access to individual cell-based therapy without the ethical and immunological ATCC細(xì)胞problems associated with human embryonic stem cells.
