Figure 8. Progressive dilatation of the ctnnb1Δex3 left atrium during the first weeks of life.

Figure 8

The Tyr::Cre/°; ctnnb1Δex3/+ ( =  ctnnb1Δex3) left atrium expands during the first postnatal month. Isolated WT (A–C) and ctnnb1Δex3 (D–F) hearts: A and D at postnatal day (P) 1, B and E at P10, C and F at P28. Scale bars, (A, D)  = 0.5 mm, (B, E)  = 1 mm, (C, F)  = 2 mm. Note that the ctnnb1Δex3 left atrium is abnormally large after P10. LA: left atrium, LV: left ventricle, RA: right atrium, RV: right ventricle.
