About this trial
Myelodysplastic syndromes (MDS) are clonal diseases of hematopoietic stem cells (HSC) characterized by dysplastic and inefficient hematopoiesis related to excessive progenitor cell death. Ferroptosis is a recently described cell death mechanism and we think that it could be a major player in the pathophysiology of MDS, involved in the cell death that characterizes these diseases and contributing to cytopenias. The study aims to demonstrate that there is a significant activation of this phenomenon in MDS patients compared to a population of subjects without MDS.
