Differentiation protocols to direct cell fate decision from pluripotent stem cells to cardiac myocytes normally achieve high purity and quality of cells. Nonetheless, the highly specialized anatomy of the heart enables the possibility that acquisition of terminal somatic differentiation from pluripotency might imply heterogeneity of non-desire cell lineages. Directed cardiac differentiation empowers differentiation of pool of cells commonly reported to contain different proportions of ventricular, atrial, and nodal-like cells. RNA sequencing (RNA-Seq) allows a precise transcriptional profiling, ensuring a quality checking of the cell identity our protocol has derived as a main outcome. Here we describe a workflow methodology on how to adapt RNA sequencing analysis for integration into the R analysis pipeline in order to characterize chamber-specific gene signatures of the major cardiac lineages of myocytes in the heart.
