An embryo is an organism in its first 6 to 7 weeks (after that it becomes a fetus). Investigation on embryos consists in using some of the stem cells - the body's master cells - on certain experiments (or taking out a cell of the stem cell). I think that research on embryos is a very good idea. It can help women that can’t have babies. It also works as a system to find new diseases and at the same time we can relate it to cloning.
Artificial insemination is a great help for women that have trouble having babies. In cases in which the man is unfertile, it is a very good option. Artificial insemination is the process by which sperm is placed into the reproductive tract of a female for the purpose of impregnating the female. In humans, it is used as assisted reproductive technology, primarily to treat infertility using sperm from the woman's partner, or sperm from a sperm donor (donor sperm) where the male partner produces no sperm. It is also increasingly used to enable women without a male partner (i.e., single women and lesbians) to have children. If a couple didn’t have a chance of parenthood while they were young and now they are too old to have a baby naturally, there is also a chance of a surrogate mother, this means that a woman who is not the wife is artificially inseminated with the man sperm and this surrogate mother carries the baby until he/she is born.
Cures may be found for previously untreatable diseases and disorders. New and improved treatments may provide insights into diseases such as Alzheimer's disease, diabetes, heart disease, kidney failure, Parkinson’s and spinal muscular atrophy by producing stem cells containing genetic defects that contribute to these conditions. These will be used as cell models for investigating new approaches to treatment, and to improve the understanding of how embryonic stem cells develop. The cells will not be used in therapy, and it is illegal to implant them into the womb. The decision taken by the Human Fertilization and Embryology Authority (HFEA) has granted one-year licenses to the scientists that first applied for permission in the autumn of 2006. Now they have created the hybrid-embryos which are made from animal eggs and they remove the genetic material and replace it with human DNA. The eggs turned into embryos from which stem cells can be harvested so that they use this instead of human eggs.
Cloning is a very important matter because it has different ends. First it can help to the multiplication of the nervous cells or neurons and these can be used with people that are unable to walk because of a broken spine. With the multiplication of neurons, doctors could fix broken spines and people could walk again. Another matter will be having children with characteristics of one of the parents in case that the other one had a disease like diabetes or epilepsy. We also have the therapeutic cloning; this is one of the most effective ways to generate tissue and organs from the genetic material. The person shouldn’t have any complications because of the immunologic incompatibility. The tissue or the organ that is going to be implanted is built from his or her own cells.
Now we know why research on embryos is so useful and at times vital. It is the solution for a family that wants to grow in number with the artificial insemination. This it is also a big help for people in general in case of a disease like Alzheimer or Diabetes. These are diseases that everybody can have in the future and with this research we can have a cure. Cloning can also help people with different types of diseases like the broken spine, mentioned before, or the therapeutic cloning which is the most effective way to generate tissue or an organ.
