【正文】 ll consider enacting a global ban on both therapeutic and reproductive cloning. Stem Cell Research Worldwide United Nations ? In November 2022, a mittee of the General Assembly defeated by only one vote a proposal to ban therapeutic cloning research. The United States delegation strongly supported this proposal. ? In September 2022, the General Assembly will again consider the proposal to ban the research. 2022。 ?北京大學干細胞研究中心。陳大元，中科院動物所 2。 ?轉基因技術生產(chǎn)的蛋白藥物審批手續(xù)冗長（ 1520年）。 8 Cloning Facts ? Plant cloning has been around for thousands of years ? Farm animal cloning has been around for over 20 years ? Cloning is a form of asexual reproduction ? Clones aren?t exact copies ? Cloned animals are safe to raise and eat Cloning Fallacies ? Geic makeup is altered ? Mutants are created ? Clones are unhealthy ? Will eventually lead to cloning humans ? Possible to recreate people such as Hitler House Bill 2505 Human Cloning Prohibition Act ? Prohibition on human cloning ? Criminal Penalty: Up to 10 years imprisonment ? Civil penalty: Minimum 1 million dollar fine Final Thoughts ? Cloning has been around for a long time ? Cloned products are safe ? Useful in medical and pharmacological fields ? Will not replace traditional animal agriculture ? Need to better educate public ? Close regulation Stem Cells amp。 ?國家干細胞工程產(chǎn)品產(chǎn)業(yè)化基地建成。魏于全，四川大學 5。 ?中國在胚胎生物技術研究方面有比較好的開始，克隆羊、 牛、大鼠。Stem Cells amp。曾溢滔、盛慧珍、陳大元、趙春華、韓忠朝、 曹誼林、陸道培，李凌松，裴雪濤等。楊雄里，復旦大學 圍繞新目標 建立具有 自我 完善機制 的 組織實體，適應帶動 傳統(tǒng)學科發(fā)展的 時代要求 虛擬組織 實體組織 目標 組織 行動 。 中國在干細胞生物技術領域的優(yōu)勢 ?國家干細胞工程技術研究中心成立投入使用。 Regenerative Medicine Transgenic Animals Transgenic Animals Outline ?
