Tippi MacKenzie, MD, is stopping disease before it starts – in the womb.
In 2017, she launched the world's first clinical trial of an in-utero stem cell transplant therapy. Her first patient, baby Elianna, was born just four months later.
Elianna's birth came after a second-trimester diagnosis of a normally fatal blood disorder. Her story hints at the lifesaving possibilities of fetal therapy for families who face similarly devastating diagnoses.
