9-Year-Old Boy Makes History Donating Stem Cells to Save Father in California

Nick Mondek, a father from Torrance, California, faced a deadly return of acute myeloid leukemia after an initial remission. His 9-year-old son, Stephen, made medical history by becoming the youngest stem cell donor at Cedars-Sinai Medical Center, donating stem cells that were a half-match and ultimately successful in replacing Nick's cancerous cells. This rare procedure was inspired by a friend's similar experience and was deemed effective due to Stephen's young age and genetic relation. Meanwhile, in Richmond, Virginia, 5-year-old Zion Ortiz was cured of sickle cell anemia after a bone marrow transplant from his 14-year-old half-sister, Marissa, who was a haplo-identical match. Both stories highlight the life-saving potential of family-based stem cell and bone marrow donations, even from young donors, providing hope for patients with severe blood diseases. Despite the challenges in recovery, these cases underscore the resilience of young patients and the critical role of family donors.
