Stem cells are blank cells that are found in the human body that have good potential to develop into a lot of different cell types that end up carrying out different functions.
They are distinguished have two important characteristics first they are unspecialized cells that are capable to renew themselves through cell division.
Second, under many certain experimental conditions they can be induced to become tissue or organ specific cells with a special functions, In some experimental conditions. Defining Stem Cell researchThere are many areas in medicine in which stem cell research can have a significant impact. For example, diseases or injuries destroy many cells or tissue. Stem cell can not only make new tissues in many cases, but you also cure the disease.Potential uses for stem cells
Why scientist use the stem cell research is for not only them but other people to gain a better understanding of how the genetics work in the early stages of cell development.
A better understanding
Embryonic Cells- are capable to make different types of body cellsThey are derived from embryos that develop from eggs that have been fertilized in vitro.In a vitro fertilization clinic it is donated for research purposes with informed consent of the donors.
Embryonic Stem cells
Adult stem cells form differently which can be induced to become other types of tissue cells. Can be less flexible than the embryonic cells though.The primary roles of adult stem cells in a living organism are to maintain and repair the tissue in which they are found. Many scientists also use the somatic stem cell where it refers to the cells of the body
Adult stem cells
The social perspective of stem cell researchHow and where the technique will be used.
Apprehensions about the techniques. Two concerns for both sides:Helps treat numerous medical problemsHave the possibility of finding cures for certain diseaseEx. Alzheimer's, Parkinson's type 1diabetes, heart disease, Stroke, spinal cord injuries, congenital defects.Can also repair or replace damaged organs Lessens risk during a transplantationCould even find a cure for cancer one dayPeoples opinions for the researchHave more to do with ethics and religion
Example of some of the main disputes are-Belief that it is a sin against their religionImposing on mother natureHumans shouldnt be experimented onFear of human clonesAborted fetuses and unethical and the research may cause abortion to seem like a good alternative

http://mediamatters.org/research/200706210016 VideoStem cell research LawsThere was never a federal law that banned stem cell research in the U.S.
It only placed restrictions on funding and use under congresss power to spendWhat did the federal law think?
In February 2001, George W. Bush requested a review of the NIHs guidelines.He then had a policy discussion with many of his supporters to make a policy to limit the number of embryonic stem cell lines that could later be used for research Georges policy
The house of representatives voted 238-194 to loosen the limitations on federally funded embryonic stem cell research.
Them then being able to use government funded research on surplus frozen embryos from in vitro fertilization clinics to be used for stem cell research with the permission of the donorsThe house of representatives
On July 18, 2006 the senate had passed three different bills concerning stem cell research.
It was to be passed to make it legal for the federal government to spend federal money on the stem cells
The second bill made it illegal to create, grow, and abort fetuses for research purposes
The third bill encouraged research that would isolate the different stem cells without the destruction of human embryosThe senate
In December 2003 a bill was passed by the New Jersey legislature that permits human cloning for the purposes of developing and harvesting human stem cells.
Mainly it legalizes the process of cloning a human embryo and implanting the clone into a womb, provided that the clone is then aborted and used for medical research.
New Jersey Legislature
Several states have shown interest in providing their own funding support of embryonic and adult stem cell research
The states that approve include: Connecticut, Florida, Illinois, Massachusetts, Missouri, New Hampshire, New York, Pennsylvania, Texas, Washington, and Wisconsin.The states that approveAccording to many studies, more people in the United States are against stem cell research than those who are for it.
