blocks of the body because as an embryo‚ the body is formed out of stem cells that transform into the various specialized cells in the body. Most stem cells in adults are cells types like muscle‚ bone or nerves‚ but they don’t preform a specialized function. When needed‚ the stem cells transform into a cell that performs a specialized function. In adults‚ stem cells are most commonly obtained from bone marrow. Other places to acquire stem cells include fetuses‚ embryos and umbilical cords. Stem cells

ES cell is created by destroying an embryo. Other scientists think ES cells will also be a promising source because it is composed of your own DNA‚ so the immune system won ’t reject the cell. While scientists would agree that the same laws should apply because they believe in finding a cure to diseases‚ other people would disagree. Some people would say that ES cells are unethical because scientists need a human egg donor‚ and they must destroy a human embryo. The laws should not be the same for

Over many years‚ the idea of genetically modifying human embryos has been an extremely controversial topic. A global network of stem cell researchers named Hixton Group released a statement claiming that genetic modification is essential to gain basic understanding of the biology of early embryos. Being able to modify and study embryos would bring tremendous value to science. Although the group didn’t particularly encourage changing embryos for personal reasons‚ they strongly believe that when all

amounts of stem cells can be found in early stage embryos in comparison to the adult human body where there are not as many present. Stem cells are “unspecialized” cells which have the potential to produce different types of specialist cells such as brain‚ muscle‚ or tissue cells. On January the 22nd 2001‚ the British House of Lords voted to relax the restrictions on the use of human embryonic stem cells. This has allowed scientists to use early stage embryos for therapeutic purposes. And whilst this has

organism that is the exact genetic copy of another. There are multiple ways that cloning can be achieved through biotechnology. Artificial embryo twinning is the more basic version of cloning. It mimics the natural occurrence of twins as a zygote divides into a two celled embryo but this process takes place in a Petri-dish instead of the mother’s body. The resulting embryos are then placed in a surrogate mother where they are developed. The process that ‘cloning’ generally refers to is scientifically known

The embryo reaches the uterus in about a week. The embryo anchors itself to the wall of the uterus where it develops into a foetus. The foetus feeds off nutrients and oxygen provided by the placental lining in the uterus. There are several conditions in both
