Salles II, Thijs T, Brunaud C, et al. Human platelets produced in nonobese diabetic/severe combined immunodeficient (NOD/SCID) mice upon transplantation of human cord blood CD34⁺ cells are functionally active in an ex vivo flow model of thrombosis. Blood. 2009;114(24):5044–5051.

On page 5044 in the December 3, 2009, issue, in the second paragraph of the Introduction, there is an error in the second sentence that read, “Such produced platelets are functional, as demonstrated in aggregation assays and by expression of P-selectin on the platelet surface or by activation of glycosylphosphatidylinositol (GPI) IbIIIa upon thrombin/thrombin receptor-activating peptide (TRAP) stimulation.^6,11-14” The text “glycosylphosphatidylinositol (GPI) IbIIIa” is incorrect. The sentence should have read: “Such produced platelets are functional, as demonstrated in aggregation assays and by expression of P-selectin on the platelet surface or by activation of GPIIb/IIIa upon thrombin/thrombin receptor-activating peptide (TRAP) stimulation.^6,11-14”
