Summary Introduction
Introduction: AIDS is one of the most dangerous and severe diseases. AIDS stands for “Acquired immunodeficiency syndrome”. The causative agent of this disease is a virus called “human immunodeficiency virus” or HIV. It is a type of retrovirus. This virus has the ability to cause a deficiency in the immune system of the body. The role of the immune system is to protect the body from harmful pathogens.

- Which statement below best describes whether or not there is an advantage of using iPSCs to induce repair of bodily damage within a patient over using embryonic stem cells that have been donated? a.
