This is a multidisciplinary study from many different professionals investigating the field of embryonic stem cells. This chapter is comprised of studies done by the Norwegian project group and deals with embryo and fetal cell development and their potential use in the field of stem cell therapy. The group examines the advantages of using embryonic stem cells in the field of medicine as well as stem cell alternatives. They look at adult stem cells and the importance they can play in research and therapy as an viable and more ethical alternative to using embryonic stem cells. Their differing views are represented continually and the authors remain divided as they represent both sides of this endless debate. The first position emphasizing the use of embryonic stem cells especially for the treatment of currently untreatable serious disease and injuries. The second position being the continuation of research on all human stem cells excepting those that come from human embryos.

This article is focused on the studies of Gabriela Cezar, assistant professor of animal science at the University of Wisconsin–Madison and her novel way of testing for drug toxicity using embryonic stem cells . By monitoring the results of these tests Cezar and her colleagues feel that they should be able to have a far more accurate prediction of a drug’s potential toxicity than they get with conventional animal testing. Cezar’s group tested the drug valproate, an anti-epileptic drug that has been linked to cases of autism and spina bifida in the offspring of mothers treated with the drug. Cezar was able to see in these tests that the ES cell samples tested with valproate exhibited significant changes in what would represent early brain development. Steven Tannenbaum, professor of chemistry and toxicology at MIT does not agree with Cezar and her findings. He points out that drugs taken into the body are processed first in the liver, not the brain, and that drug metabolism in the body is a very complex process. Recognizing the abilites to have embryonic stem cells develop into liver cells, Cezar feels that the research she is doing is capable of bringing safer and more effective drugs to the consumer.

The therapeutic uses of stem cells are of course, the main reason for stem cell research. In this chapter the authors recognize that the current therapeutic applications of hematopoietic stem cells (HSC) such as in bone marrow transplantation have been successfully treating patients with Leukemia and Lymphoma for many years. Umbilical cord stem cells have also been used to treat blood disorders and are especially preferred in pediatric patients. The experimental therapeutic applications noted by the authors include testing with patients who have multilple sclerosis. Neural stem cells (NSC) and embryonic stem cells (ESC) have both shown signs of effectiveness against this disease. Potential therapeutic applications for use in Parkinson’s disease, spinal cord injury, retinal degeneration, Diabetes, and cardiovascular disease are being researched and tested using HSC, NSC and ESC. Testing with different types of stem cells is important to the research. It enables the scientists to learn which therapy might cause potential problems with immune rejection for the patient. Autologous transplantation has been found to eliminate the problems of rejection for the patient since those stem cells come from the patient who is being treated. Research continues to show improvements in the current therapeutic applications as well as in the experimental and potential phases of stem cell therapy.
