Controversial Technique Could Prevent Genetic Disease by Making 3-Parent Babies April 14th, 2010 The researchers outline their work in a study in this week’s Nature. On the surface, the idea is fairly simple. They took the nuclei out of the father’s sperm and the mother’s egg, and transplanted them into a donor’s egg cell that had its nucleus removed, but whose mitochondria remained in the cell’s cytoplasm. What you get is the genetics of both parents, plus the mitochondrial DNA of the host. This technique was pioneered in monkeys last summer, but researchers have now done a proof-of-principle study with human cells. blogs.discovermagazine.com/80beats/2010/04/14/controversial-technique-could-prevent-genetic-disease-by-making-3-parent-babies/

Babies with THREE parents and free of genetic disease could soon be born using controversial IVF technique Last updated at 1:44 AM on 12th March 2011 www.dailymail.co.uk/health/article-1365287/Babies-THREE-parents-born-years-controversial-IVF-technique-gets-ahead.html# pre-implantation genetic diagnosis, screens embryos created in the lab for the faulty DNA # extra mitochondrial DNA inherited from the donor does not alter a child’s appearance or personality # "mitochondria transplant is little different from having a blood transplant, or being given a new heart valve or kidney" # around 100 babies every year are born with disease caused by faulty mitochondrial DNA # couple who lost six babies to genetic disease suffer devastating blow when their only surviving son dies, aged 21 # mitochondrial DNA is only passed down from mothers # ‘If it’s a girl, then those changes will be passed down to all her descendants.’

There are 2 kinds of DNA in our bodies 1. nucleic DNA (containing the genetic instructions used in the development and functioning of all known living organisms (with the exception of RNA viruses)) 2. mitochondrial DNA - through mothers 9:40 guar cell gestated in ovum of cow w/cow mitochondrial DNA mouflon gestated in a regular sheep w/sheep mitochondrial DNA Paul Root Wolpe: It's time to question bio-engineering www.youtube.com/watch?v=ovV7v2XYJAI

Cloning a Woolly Mammoth: Good Science or Vanity Project? Wednesday, March 14, 2012, at 5:15 PM E Scientists in South Korea and Russia agreed Tuesday to try to clone a woolly mammoth, according to the Wall Street Journal. The scientists intend to make a wooly mammoth embryo by replacing the nuclei of an elephant cell with that of a woolly mammoth cell (presumably from the remains of a mammoth uncovered in Siberia last year). Then they would use an elephant as a surrogate, according to the Journal. One of the leaders of the endeavor, Hwang Woo-suk, has a patchy history with cloning. He rose to fame in 2004 and 2005 with claims that he and his team had made a human embryonic stem cell. Their data turned out to be false. Since then, Hwang has made an attempt at a comeback. In October 2011, after he became the first to clone a coyote, he announced his woolly-mammoth plans. www.slate.com/blogs/future_tense/2012/03/14/cloning_a_woolly_mammoth_hwang_woo_suk_and_other_scientists_attempt_to_revive_exinct_species_.html******************** Mammoth clone is coming: Russians ink deal with Korean biotech firm 19 March 12 The bone, which was found under the Siberian permafrost in Summer 2011, contains enough bone marrow, the researchers believe, to create embryos with mammoth DNA. Those embryos could then be implanted into an elephant womb, whose owner would then give birth to the first hairy pachyderm to be seen by humans in millennia. The deal was signed by Hwang Woo-Suk of South Korea's Sooam Biotech Research Foundation and Vasily Vasiliev, the vice rector of North-Eastern Federal University of the Sakha Republic. It's the second deal to be done with the bone marrow -- the first was with Kyoto University, with the same goal in mind. www.wired.co.uk/news/archive/2012-03/19/mammoth-clone-is-coming
