In gene therapy of Adenosine Deaminase (ADA) deficiency, the patient requires periodic infusion of genetically engineered lymphocytes because:
| 1. | Genetically engineered lymphocytes are not immortal cells. |
| 2. | Retroviral vector is introduced into these lymphocytes. |
| 3. | Gene isolated from marrow cells producing ADA is introduced into cells at embryonic stages |
| 4. | Lymphocytes from patient's blood are grown in culture, outside the body. |
