Stem cell research has been a very controversial issue. Why? Most of the research has been done with the usage of embryonic stem cells. This is where the controversy begins. There are two types of cloning embryo splitting and nuclear transfer. According to the article, “Blood Vessels Made from Stem Cells,” the extracting of the cells kills a living human embryo. However, President Bush decided that there would be federal funding for stem cell cultures that already exist. This would prevent any further killing for research purposes of other human embryos.

Researchers argue that the use of embryonic stem cells would them the opportunity to develop embryo into cells that make up the organs, bone, skin and other tissues. In this research they hope to direct the transformation of such cells to treat ailing hearts, livers, brains, and other organs, according to the article, “Blood Vessels Made from Stem Cells.”

Nuclear Transfer on the other hand is a simple procedure. The nuclear material is removed from an egg via microinjection or electrofusion, and resulting reconstituted zygote is activated. The reconstituted zygote has the potential to divide i

Medically, the process is safe but some argue about where these cells are coming from. Would women be subjecting themselves to having unwanted babies for the sake of research? Some say that this would advance is medicine would help many people medical disorders such as cancer, diabetes, and Parkinson\'s disease. Many countries continue their research and there is even speculation of a possible human clone. Stem cell research in the United States according to President Bush will continue to be funded however there will not be any new human cells obtained.

nto blastocyst, and if implanted, develop into a child genetically identical to the nuclear donor. There are two types of human cloning by nuclear transfer: reproductive cloning and therapeutic cloning. The objective of the reproductive cloning is to produce a child genetically identical to an individual. The objective of therapeutic cloning is to produce embryonic stem cells that are genetically identical to a patient.#

Currently, federal statute prohibits research that destroys embryos. Stem cells derived from such parthenogenetically activated cells would be unlikely to be rejected after transplantation because they would be very similar to a patient’s own cells and would not produce many molecules that would be unfamiliar to the person’s immune system. (They would not be identical to the indiv
