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。 Regenerative Medicine Science of Stem Cells? ? Stem cell research has potential to contribute to new therapies and improved quality of life. ? Late 1998 a group of scientists, led by James Thomson, at UW Madison were the first to isolate and culture human embryonic stem cells. ? Revolution in medicine amp。 ?轉(zhuǎn)基因技術(shù)生產(chǎn)的蛋白藥物審批手續(xù)冗長（ 1520年）。 ?籌建中的北京國家生物研究所。陳大元，中科院動(dòng)物所 2。盛慧珍，中科院 4。 ?北京大學(xué)干細(xì)胞研究中心。 ?政府的支持，反對(duì)生殖性克隆人，允許治療性克隆研究 。 provide unlimited source of adult cells like bones, muscle, liver or blood cells. ? Originally produced to treat infertility and surplus embryos were discarded. ? Embryos created using IVF then tested using DNA analysis when only 3 days old and only a few cells in size. Embryonic Stem Cells: Researchers extract stem cells from a 57 days old blastocyst. Stem cells can divide in culture to form more of their own kind, thereby creating a stem cell line. The research aims to induce these cells to generate healthy tissue needed by patients.
