Claudio Bordignon, an Italian geneticist, died on March 30, 2026.
In 1992, while working at Vita-Salute San Raffaele University in Milan, he carried out the first gene therapy procedure using hematopoietic stem cells as vectors to deliver genes intended to correct hereditary diseases. The effort was a world first, although it did not achieve sustained correction of the hematopoietic stem cells.
In 2005, he was named by the European Commission as one of the 22 founding members of the European Research Council.
