Erratum for Cobaleda et al., Blood 95 (3) 1007-1013

Notice of plagiarized text

Following publication of the article “A primitive hematopoietic cell is the target for the leukemic transformation in human Philadelphia-positive acute lymphoblastic leukemia” in the February 1, 2000, issue ofBlood, by Cobaleda, Gutiérrez-Cianca, Pérez-Losada, Flores, Garcı́a-Sanz, González, and Sánchez-Garcı́a (Blood. 2000;95:1007-1013), large portions of the text were found to be plagiarized from an article previously published by Bonnet and Dick, “Human acute myeloid leukemia is organized as a hierarchy that originates from a primitive hematopoietic cell” (Nature Medicine. 1997;3:730-737). The essential research and the findings of the article by Cobaleda et al are original and worthy of publication; however, the improper use of text from the article inNature Medicine is a direct violation of copyright law and betrays the assumed professional conduct of all authors submitting manuscripts to Blood.
