Ok, now on to your questions...
Hi Julie, there are two types of human cloning, reproductive cloning and therapeutic cloning and each has its own potential benefits. Reproductive human cloning involves the production of a cloned human child, thus a potential benefit of reproductive cloning would be to allow the completely infertile to conceive a genetically related child. Therapeutic human cloning involves the production of embryonic stem cells that are genetically identical to a patient, thus any stem cell based medical treatments using these cells would not be rejected by the patient’s immune system. These are the primary benefits of reproductive and therapeutic cloning.

2. can u show me the statistic of human cloning?
3. is it safe enough to clone human ?
Hi Hin, I’ll try to answer your questions in the order you posed them.
1. The advantage of reproductive human cloning, as I mentioned above, is that it would allow the infertile to conceive a biologically related child. The disadvantage of reproductive human cloning is that it is an inefficient procedure and the safety for mother and child is questionable. The advantage of therapeutic human cloning is that is may lead to stem cell based cures for degenerative diseases, the disadvantage of therapeutic cloning is that you have to create and destroy a human embryo to get the stem cells and this is anathema to some.
2. The current statistics of human cloning relate only to the production of blastocysts (highly developed embryos) and in 2004 Stojkovic and coworkers demonstrated that after about 30 nuclear transfers they were able to obtain 1 cloned human blastocyst. So the blastocyst production efficiency for human cloning is around 3%. What is not known is how many cloned human blastocysts would be required to initiate a pregnancy or to derive a cloned embryonic stem cell line.
3. The problems we have observed following some of the animal cloning experiments mean we should be cautious in advancing too rapidly with human reproductive cloning. It would be prudent to perform reproductive cloning in other primate species first to establish the safety of primate cloning before attempting to clone a human child.

Hi Mike, cloning is a simple process whereby the DNA from an oocyte (egg) is removed and replaced with the DNA of an adult donor cell. The oocyte reprograms that adult DNA to think it is embryonic DNA again and embryonic development proceeds normally from there, with the one exception that any offspring produced from this cloned embryo would be genetically identical to the adult cell donor. I hope this answers your question.
