Erratum for vol. 97, p. 3925

In the article by George et al entitled “Detection of leukemic cells in the CD34⁺CD38⁻ bone marrow progenitor population in children with acute lymphoblastic leukemia,” which appeared in the June 15, 2001, issue of Blood (Volume 97:3925-3930), the second and third sentences of the next-to-last paragraph should have read: “Of a total of 1.1 × 10⁴FACS-sorted CD34⁺CD38⁻ cells from 5 cord blood samples, 17 clones were analyzed and with the exception of a single clone, no Vδ2-Dδ3 rearrangements were found. Rearrangements were found with much greater frequency in the CD34⁺CD38^dim and CD34⁺CD38⁺ fractions, and were possibly concomitant with lymphoid commitment as demonstrated by the expression of CD7 and CD19.”
