March of Dimes Honors Stem Cell Pioneer Dr. Leonard Zon for Breakthroughs in Blood Disorders
Event summary
- Dr. Leonard Zon awarded the 2026 March of Dimes Richard B Johnston Jr, MD Prize for developmental biology contributions.
- Zon's zebrafish research led to discovery of ferroportin gene, critical for maternal-fetal iron transport.
- Prostaglandin E2 discovery improved stem cell transplant success rates by 400% for leukemia patients.
- Zon's work on Diamond-Blackfan anemia treatment nearing human clinical trials.
- Spinal muscular atrophy treatment developed by Zon's company under FDA review.
The big picture
The recognition of Dr. Zon's work highlights the growing importance of developmental biology in addressing rare pediatric diseases. His zebrafish model research has produced tangible clinical applications, demonstrating the value of innovative biological models in drug discovery. The March of Dimes' award underscores the strategic focus on maternal and infant health innovations that can transform treatment paradigms for genetic blood disorders.
