The need to provide greater attention to research into the biological and experimental aspects of hematological diseases has been a growing concern within the Italian Society of Hematology since the early 1970s. This is why GESSIE (Italian Group of Experimental Hematology of the SIE) was founded.
The vigorous development of biological studies in the field of hematology in the late 1970s and throughout the 1980s had rendered this structure insufficient, thus making it necessary to create a new society, parallel and synergistic to the SIE, with the aim of giving greater space to the biological and experimental aspects of hematology.
