[From the bench to the clinic: The challenge of translating platelet production in vitro].

Platelet transfusions, which are currently totally dependent on altruistic donations, are absolutely necessary to the treatment of patients with thrombocytopenia following trauma, surgery or other pathologies (especially malignancies). Producing platelets in vitro represent a major technological and scientific breathrough that would address logistical issues (supply chain, stock holding…) and medical concerns (compatibility and biosafety). The translation of this innovation will need to be accompanied by rigorous quality control, harmonised between laboratory when it comes to functionality and biosafety for use in the clinic.
