In the article "Reduced Expression of P2Y1 Receptors in Connexin43-Null Mice Alters Calcium Signaling and Migration of Neural Progenitor Cells," by Eliana Scemes, Nathalie Duval, and Paolo Meda, which appeared on pages 11444-11452 of the December 10, 2003 issue, the wrong version of Figure 4 was used. The correct version of Figure 4, as well as the legend, is printed here.

Figure 4. P2Y1 and P2X7 receptors participate in spontaneous calcium oscillations of WT and Cx43-null neural progenitors. A, Wild-type neural progenitor calcium transients induced by bath application of 30 µM 2-MeS-ATP (2-Mes; arrow) were totally prevented by the specific P2Y1R antagonist MRS-2179 (MRS; 5 µM). B, The potent P2X7R antagonist KN62 (1 µM) blocked calcium transient induced by 100 µM BzATP in Cx43-null progenitors. Spontaneous intracellular calcium oscillations recorded from fura-2 AM-loaded (2.5 µM) WT (C) and Cx43-null (D) neural progenitors were prevented by bath application of 5 µM MRS-2179 and 1 µM KN62, respectively. The oscillations of each cell are represented by black and gray traces.
