TIDMARSH, SHELLY HEIMFELD, CHERYL A. WHITLOCK, IRVING L. WEISSMAN, ¨ AND CHRISTA E. MULLER-SIEBURG Laboratory of Experimental Oncology, Department of Pathology, Stanford University School of Medicine, Stanford, California 94305 Volume 9, no. 6, p. 2665–2671: We reported that a population of Thy-1lo B220 mouse bone marrow cells contained lineage-committed progenitors that could give rise to large numbers of B cells in vivo yet lacked clonogenic myeloerythroid precusors and were also enriched for Abelson leukemia virus transformation to pre-B leukemia clones. Subsequently, the finding that Thy-1lo B220 cells were significant and specific progenitors for large numbers of B cells in vivo could not be repeated, and this was reported by S. Morrison, E. Lagasse, and I. L. Weissman (Blood 83:3480, 1994). It was reported in the Blood article that Thy-1lo B220 mouse
