What is the difference between ex vivo and in vivo gene therapy?
What will be an ideal response?
In ex vivo gene therapy, tissue such as bone marrow stem cells or liver cells is removed from the patient. The patient's cells are then infected with a virus that carries a normal gene and then returned to the body. With in vivo gene therapy, the gene is delivered directly into the body. In cystic fibrosis, the gene needed may be sprayed into the nose or delivered to the lower respiratory tract by adenoviruses or by the use of liposomes.
