Discuss the ethical issues of

therapeutic cloning in humans.

What is therapeutic cloning? Therapeutic cloning is the creation of an embryo

to supply embryonic stem cells for medical use. Creation of a ‘new’ egg cell using the DNA of a

desired differentiated cell and a doner egg cell

What is it not? Creating a mini-me for use in evil global

domination plots or to create armies! Creating a copy of human to use as an ‘insurance

policy’ in case you need a transplant.

Arguments for therapeutic cloning.

No need to wait for human donor to die to give organs

Some successes already have been shown throughout the world

Rejection risk reduced in transplants

Conservation of biodiversity

Potential cure for incurable disease

Arguments against therapeutic cloning.

Religions affiliation– ‘playing God’??

Possible risk of facing first human clone

Too difficult and effort-taking

Genetic diversity?

Abnormalities in clones

What should we do?
