totipotency 中文意思是什麼

totipotency 解釋
核的全能性
  1. Different from mammals, the early embryos of fish can not be preserved for the long period at the very low temperature ( - 196 ). therefore, three methods were usually applied to cryogenic preservation of the fine and rare species of fish : 1 ) perserving fish spermatozoon in cryogenic condition. researchers have had systematically studied on this technique for many years, and this technique has been utilized in application and made a lot of effects ; 2 ) combining with the techniques of cell engineering ( nuclear transplantation and electric fusion etc. ), and through the process of culturing histiocyte of fish, cryopreservation and re - culture after thawing, carrying out somatic cell breeding of fish. the past studies showed that the nucleolus of somatic cells of fish have totipotency

    多年來，國內外學者對各種魚類精液的冷凍保存進行了大量的系統研究，目前這項技術已達到實用水平，並日益發揮作用；二是對魚類培養的組織細胞冷凍保存，通過魚類細胞的培養、超低溫凍存、解凍后再培養過程，結合細胞工程技術（如核移植、電融合等）進行體細胞育種；大量的研究結果表明魚類體細胞核具有發育的全能性，隨著細胞培養技術、細胞工程技術日益發展成熟，完全具備實現魚類物種種質長期保存的理論基礎和技術條件。
  2. According to dr lanza, the evidence from other mammals is that the individual cells of a developing embryo have lost totipotency by the eight - cell stage

    據蘭澤博士稱，根據對其他哺乳動物的研究發現，發展中胚胎的單個細胞在發展到八細胞階段（即卵裂球）時就喪失了其萬能性。
  3. Totipotency the ability shown by many living cells to form all the types of tissues that constitute the mature organism

    全能性：生活細胞具有的能發育成為各種組織並進一步形成整個生物體的潛力。
  4. The ensuing gene expression profile in the cleavage - stage embryo establishes totipotency and is required for further development

    隨后卵裂時期胚胎的基因表達模式將建立一種全能性，這對進一步發育是必需的。
  5. In these years, because of its totipotency, manipulation and plastics, the embryonic stem ( es ) cells have been the focus of researches in the fields of medical and life science

    近年來，胚胎幹細胞（ escells ）以其具有全能性、可操作性和可塑性等諸多優點，已經成為醫學和生命科學領域研究的熱點之一。
  6. With the development of the technology of cell culturing and cell engineering, so it is possible to preserve fish species for a very long time. 3 ) using embryonic stern cells ( es ). fish embryonic cell has the totipotency and is better f or breeding than somatic cell, but it can not so strong to resist the very low temperature

    三是通過es途徑。魚類胚胎幹細胞具有發育的全能性，利用魚類胚胎細胞育種比體細胞更具有優越性，但耐超低溫性不強，只有少數學者對魚類胚胎細胞進行凍存及發育潛能的研究，還沒有對魚類胚胎細胞進行凍存培養的系統研究。
