Correction to: Phases and Mechanisms of Embryonic Cardiomyocyte Proliferation and Ventricular Wall Morphogenesis

Abstract

The original version of this article unfortunately contained a mistake. In reviewing the phenotype associated with Mapk14 (p38alpha MAPK) mutation as evaluated by Adams et al. (2000) using tetraploid aggregation chimeric embryos, the authors mistakenly stated that rescue of embryo lethality was short-lived and that embryos died two days later of non-placenta-related causes. In fact, as reported by Adams et al. (2000), when the placental defect of global null embryos was rescued, p38alpha(-/-) embryos developed to term and were normal in appearance. The authors apologize for the error.
