The patient will need to be in the hospital for at least 3 weeks after the transplant to make sure the transplant has engrafted. We will do several tests (of the lung, kidney, and liver) before and after the bone marrow transplant. We want to find out how much the treatment has helped the patient and how much it might help other patients. Most tests will be done every week for 4 months and at each visit to the hospital. Also, we will be looking at the immune function. To do this, we will take about 8 ml (less than 2 teaspoonful) at 6 months, 1 year, and 2 years after the transplant. When possible, we will take the blood from an IV line that the patient already has. However, at times we will have to draw the blood with another needle stick. A total amount of 200 mL (about 13 tablespoons) of blood will be collected from the patient during the entire study.
