Transcript of Stem Cell Research

Stem Cell Research The Pros of Stem Cell Research 1. Adult Cells Cord Cells Adult Stem Cells can be found in:
1. bone marrow
2. peripheral system

Bone marrow is a good source of stem cells
But painful and harmful destruction of bone marrow.

Peripheral System can be taken without harm to the bones, but the procedure takes more time, which some people don't have. Adult Stem Cells They are extracted during the stage when the cells have not differentiated.
Since the cells are not differentiated, they can be grown into basically any part of the body.
The stage at which they are extracted are called blastocysts.
Blastocysts contain about 100 stem cells. Embryonic Stem Cells They can be used as a perfect match for family members, such as mother and fathers.

The cells are extracted during pregnancy and stored in cryogenic cell banks. Pros of Stem Cell Research 1. Can be used to help cure many
diseases that would dramatically affect a person's life.

2. Replace or Repair damaged organs

3. Reduce Risk of Transplantation

4. Economic Gains for society Main Controversies Is using Embryonic Stem Cells considered abortion? Moral Acceptability of Stem Cell Research Embryonic Stem Cell Who Can Benefit from Stem Cell Research? - Where Do Stem Cells Come From? Potential Uses of Stem Cell Research Number of People Who Could Benefit 5.8 million Americans have heart failure
670,000 people are diagnosed with heart failure each year
23.6 million Americans have diabetes
5-10% of those people have Type 1 Diabetes
1 million Americans live with Parkinson's disease http://science.howstuffworks.com/life/cellular-microscopic/stem-cell.htm) 2. Cord Cells 3. Embryonic Cells When Does Human Life Begin? The major controversies with stem cell research are if embryonic stem cells are considered abortion. The potential benefits of stem cell research outweigh the potential harms. Adult Stem Cells can be found in:
1) bone marrow
2) peripheral system They can be used as a perfect match for family members, such as mother and fathers. The cells are extracted during pregnancy and stored in cryogenic cell banks. Success Story There was a patient who suffered from Stargardt's macular dystrophy for 20 years. (That is a form of macular degeneration.) The patient joined the stem cell research trial hoping that it would make a difference in the patient's life and in the patient's disease. The patient had a growing blind spot in the middle of the patient's vision. After having embryonic stem cell treatment, the patient's vision improved dramatically.
"I noticed my vision was so much better overall, and the blind spot in the middle seemed to be smaller."
This patient's vision has improved to 20/800. Meaning that the patient does not use reading glasses as much as before.

While Stem Cell Research is not perfect, this is one of many cases that has been treated and seen improvement in a disease, making lives better. Work Cited What Are Stem Cells? Stem cells are distinguished from other cell types by
two important characteristics:
First, they are unspecialized cells capable of renewing themselves through cell division
Second, they can be induced to become tissue- or organ-specific cells with special functions
Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth.

at conception
when the fetus has a heart beat
when the child is born
Interdisciplinary Approach to the Concept of Person (Houstin 1982)
scientific point: person hood covering subjective awareness including personality- sense of self, consciousness, social status rights and obligations
biology can not explain when person hood begins Works Cited"Embryonic Stem Cell Research Pros and Cons." Embryonic Stem Cell Research. Embryonic Stem Cell Research, 20 Apr. 2010.
