Mislabelling of a histological section caused the wrong micrograph of a wild-type control to be inserted in Fig. 5b (bottom panel, middle column) of this Article: as published, this is identical to the control bone picture shown in Fig. 3c (top left panel). The panel that should have been shown in Fig. 5b (see below) is from the Rag2-mutant mouse; the figure legend remains the same. The mix-up with the control figure does not affect the validity of the data or our original conclusions.
