Embryo And Stem Cell Research

Because we don't know where they come from naturally in the body.

Because studying stem cells teaches us about early reproduction, genetics, and disease.

Because we have growing funding and no restrictions to study stem cells.

All of the above.

Reprogrammed mature cell that is like an embryonic stem cell, without the need to destroy an embryo.

Reprogrammed mature cell that will replace the need to study embryonic stem cells.

Reprogrammed mature cell that will replace the need to study adult, foetal and cord blood cells.

All of the above.

They think someone might use any kind of stem cell technology to try to clone a person.

They think scientists who try to grow body parts out of stem cells are playing God.

They are against studies on animals that are required before studies in people.

All of the above

An unfertilised egg.

The trophoblast.

The inner cell mass of a blastocyst.

Foetal tissue obtained from a post-implantation embryo.

Develop into a whole organism when implanted into the womb.

Make more stem cells in culture under appropriate conditions.

Prevent tumor formation.

None of the above

Cells that is made up from the stem of a tree.

A cell that can divide and give rise to specialised cells.

A part of the tissue that forms the outer layer of the skin in human beings.

None of the above.

Stem cells can undergo cell division ever after long periods of inactivity.

Stem cells can be induced to become a specific cell for special functions.

Both

Differentiate into specialised cells of other tissues.

Maintain and repair the tissue in which they are found.

Give rise to sperm cells or egg cells.

All of the above.

ESC can be all cell types in the body and ASC is limited to the cell types of their tissue of origin.

ESC can be grown in massive quantities in laboratory conditions and ASC cannot.

Both

The subject cannot get pregnant again.

It is an ethical issue since it kills the embryo, which is a potential life.

It increases inflammation in the subject.

All of the above

Regenerate cells of the immune system.

Replace neurons after an accident.

Repair damage to heart muscle after a heart attack.

All of the above are potential therapeutic uses of embryonic stem cells.

Cells cultured in Petri dishes.

Unused sperm frozen in sperm banks.

Unused embryos from in vitro fertilisation clinics.

Embryos removed from animals.
