title: MicroRNAs in a cardiac loop: progenitor or myocyte?
abstract: Like transcription factors, microRNAs are emerging as regulators of cell fate decisions. In this issue, Wang et al. (2010) identify a critical microRNA pathway under the control of Bmp signaling that promotes outflow tract myocardial differentiation from cardiac progenitors in vivo.
