Severe Combined Immunodeficiency – Bone Marrow Transplant

Joshua Marshall was born with a rare disease, called severe combined immunodeficiency, which impairs his immune system so much that even a minor infection could cost him his life. Thanks to an anonymous cord blood donor, and the transplant team at UPMC Children’s Hospital of Pittsburgh who performed a cord blood transplant when he was 6 months old, Joshua has a mostly functional immune system. Now 7 years old, he is able to play outside on the family farm and enjoy just being a kid.
