Question

In the ex vivo method, which patient cells are extracted before the vector introduces the healthy gene?

Options

• Genetically disabled retrovirus

• Reproductive cells (egg/sperm)

• Patient's target cells (e.g., lymphocytes)

• Future generations

Answer 1

Patient's target cells, such as lymphocytes, are extracted for ex vivo modification. They are modified outside the body before being reintroduced.
