Chapter 23, Problem 1SL
Summary Introduction
To determine:
An ethical argument in favor and against of using human stem cells to produce human organs inside the developing pigs.
Introduction:
Scientists are trying their best for developing pig-human liver chimeras. They use stem cell of humans to produce the human organs inside the developing pigs. The goal behind this approach is to reduce the transplantable organ shortage.

Students have asked these similar questions
How are stem cells shielded from the contents of the small intestine?
a. By their tissue organization
b. By their construction and maintenance
c. By their location and by mucus
d. By their self-renewing properties
Pig organs may soon be used for organ transplants. How are researchers attempting to prevent rejection of the pig organs by human recipients?
Human embryonic stem cell research uses stem cells cultured from the blastula. These cells are pluripotent, meaning that these stem cells can develop many different types of human cells. Identify the part of the blastula that they are using and explain your choice.
