A technique that unites the egg and sperm in a laboratory instead of inside the female body.
What is in-vitro fertilization?
100
Cells with the ability to divide for indefinite periods in culture and to give rise to specialized cells.
What are stem cells?
100
A common form of dementia, that currently is irreversible.
What is Alzheimer's Disease?
100
Debate over this type of cell is said to boil down to whether or not one finds abortion morally acceptable.
What is an embryonic stem cell?
200
In humans, the developing organism from the time of fertilization until the end of the eighth week of gestation, when it is called a fetus.
What is an embryo?
200
Primitive (undifferentiated) cells that are derived from preimplantation-stage embryos, are capable of dividing without differentiating for a prolonged period in culture.
What is are embryonic stem cells?
200
A disorder of the brain that leads to shaking (tremors) and difficulty with walking, movement, and coordination.
What is Parkinson's Disease?
200
Research that involves balancing the ethics of destroying what could potentially be considered human life, against the potential benefits of the research to many living individuals with degenerative diseases.
What is embryonic stem cell research?
300
The state of a single cell that is capable of differentiating into all tissues of an organism.
What is pluripotency?
300
A relatively rare undifferentiated cell found in many organs and differentiated tissues with a limited capacity for both self renewal and differentiation.
What is a somatic or adult stem cell?
300
Virus that stops the immune system from functioning.
What is HIV(Human Immunodeficiency Virus)?
300
Ethically, considered the "safest" of all stem cell research.
What is adult stem cell research?
400
Having the ability to develop into more than one cell type of the body.
What is multipotency?
400
A type of pluripotent stem cell, similar to an embryonic stem cell, formed by the introduction of certain embryonic genes into a somatic cell.
What is an Induced Pluripotent Stem Cell?
400
A disorder passed down through families in which nerve cells in certain parts of the brain waste away, or degenerate.
What is Huntington's Disease?
400
Ethical implications of this type of research involve potential harm to a fetus, as well as knowledge of fetal abnormalities that could lead to an abortion.
What is amniotic stem cell research?
500
The process whereby an unspecialized embryonic cell acquires the features of a specialized cell such as a heart, liver, or muscle cell.
What is differentiation?
500
Cells found in the amniotic fluid that surrounds a fetus. They similar to the embryonic stem cells, but research has shown that they can differentiate into more cell types than adult stem cells.
What is an amniotic stem cell?
500
A nervous system disease that attacks nerve cells called neurons in your brain and spinal cord.
What is Amyotrophic Lateral Sclerosis (ALS)?
500
This type of research brings up many ethical questions because there is the potential to do more harm than good, if the cells are unable to stop dividing once introduced to the body.
