After the client undergoes a myeloablative conditioning program with Busulfan to facilitate engraftment9, the modified CD34+ cells are infused back in the patient intravenously. These cells journey from the bloodstream to the bone marrow, in which they engraft, proliferate, and differentiate into leukocytes that secrete useful ARSA enzymes. This enzyme allows degrade sulfatides in surrounding cells, thereby mitigating the indicators of MLD9.
