imaged by confocal microscopy (FV1000, Olympus). Results and discussion To track the descendants of Nkx2-5-expressing progenitors, we used the Cre-loxP lineage tracing approach [12]. Prior to Cre recombination, a floxed stop cassette in Rosa26fsLz prevented b-gal expression, as demonstrated by the absence of X-gal staining in
