【正文】
pluripotent stem cell, iPS):一類通過基因轉染等細胞重編程技術人工誘導獲得的,具有類似于胚胎干細胞多能性分化潛力的干細胞。胚胎干細胞系(Embryonic stem cell line):在體外培養(yǎng)的條件下,可保持未分化狀態(tài)連續(xù)增殖的胚胎干細胞。全能性(Totipotent):是早期數天胚胎中,具有分化成機體所有類型細胞和形成完全胚胎能力的干細胞。亞全能性(Pluripotent):是具有形成機體各種類型細胞,即所有三胚層來源細胞的能力,但不具有形成胚外胎組織細胞的能力。多能性(Multipotent):是指具有形成機體內超過一種類型細胞的能力,但往往是針對特定細胞系列的。滋養(yǎng)層細胞(Feeder layer):是指通過細胞細胞相互作用,或分泌蛋白或其他物質,位于胚胎干細胞和iPS細胞的培養(yǎng)底層,以支持這些干細胞生長的動物源性或人源性細胞。畸胎瘤(Teratoma):一種含有三個胚層組織細胞和分化的組織的良性腫瘤。參考文獻:1.《人體細胞治療研究和制劑質量控制技術指導原則》(2003)2.《中華人民共和國藥典》2010版,第三部。3.
