Where do nucleotide booths come from? A staunch cell is a primitive showcase of cell that dirty dog be developed into developing into most of the 220 types of cells found in the piece body (e.g. blood cells, heart cells, brain cells, etc). Some researchers union them as offering the greatest potential for the alleviation of tender suffering since the development of antibiotics. Millions of Americans suffer from diseases that may make uptually be treated more effectively with stem cells or even cured. These include heart disease, diabetes, and certain types of cancer.
Stem cells can be extracted from truly young human embryos typically from surplus frozen embryos leave over from in-vitro fertilization procedures at fertility clinics.

However, pro-life organizations object to the use of embryos. They feel that a few-days-old embryo is a human person. Extracting its stem cells kills the embryo. Many argue that since the bracing embryos will be destroyed; why not use them for research instead? Research gives the life of the embryo heart and soul as opposed to being washed down the drainage and destroyed.
There are several alternatives to using embryonic stems cells.
Stem cells can now be grown in the laboratory: about research can be done using brisk stem cells. Stem cells can also be extracted from full-grown tissue, without harm to the subject. Unfortunately, they are difficult to remove and are gravely limited in quantity. There is some evidence that indicates that pornographic cells may be more flexible than previously thought. Yet, the pursuance show promise to millions:
1. A type of embryonic stem cell, called a neural crest stem cell, that persists into adulthood in hair follicles was recently...
