(PGD) is the process of identifying genetic defects within an embryo before implantation‚ PGD allows the embryos DNA to be studied for mutations and genetic diseases. Originally PGD was used on female embryos and was used to prevent pregnancy termination in pregnancies with high risks of a sex linked genetic disease. Process The IVF procedure consists of ovarian stimulation‚ egg retrieval‚ egg fertilization‚ embryo development‚ and embryo transfer. Ovarian stimulation is needed to produce multiple

This case study is based on facts and concerns that much of the research done on embryonic stem cells is derived from human embryos. This case study will provide others with a more in depth view of both sides of this great debate. In biological terms‚ embryonic stem cells posses a virtually unlimited future.

The debate behind embryonic stem cells has caused society to choose between its responsibility to prevent or alleviate suffering and its responsibility to respect the value of human life. The use of embryonic stem cells is unethical because there are currently several alternatives that have a similar effect for the patient.

pluripotent stem cells; this means that they are able to grow into all three primary germ layers: ectoderm‚ endoderm and mesoderm and make every type of cell in the body. They result from the inner cell mass of a blastocyst; and early stage human embryo. Embryonic stem cells are used in research to improve our understanding of body development from a fertilized egg and to provide awareness into how adult tissues can be repaired or maintained.

primary cells that can be trained to develop into any human cell tissue such as muscle‚ skin‚ and brain. However‚ in embryonic stem cell research‚ to retrieve stem cells from embryos requires a process called therapeutic cloning where a person’s DNA is put into an unfertilized human egg (effectively cloning a person)‚ the embryo is then grown for a few days before it is destroyed‚ producing stem cells identical to the donor person‚ supposedly‚ without any likelihood of rejection once injected.

human is the result of sperm fertilizing an egg. After the fertilization‚ the embryo is composed of a single cell with its own DNA structure. Having an abortion is more like killing a unique cell. A human is defined as having self awareness and acknowledgement of being a “human”‚ which proves the embryo baby is not a actually a human being so aborting it would be as normal as destroying a tumor. The unborn is an embryo or a fetus-just a simple blob of tissue‚ a product of conception-not a baby. Abortion

remove the nucleus‚ which contains the genetic material‚ from an egg. The genetic material from an adult somatic cell is removed and placed in the egg. It now has a complete set of genes. The egg is placed in a petri dish to allow it to develop into an embryo‚ which is placed into a surrogate mother to continue to grow and develop into a baby (Genetic Science Learning Center). This technique is called nuclear transfer or nuclear transplantation because they transfer the nucleus from one cell to another
