Ventricular, atrial, and outflow tract heart progenitors arise from spatially and molecularly distinct regions of the primitive streak.
The heart develops from 2 sources of mesoderm progenitors, the first and second heart field (FHF and SHF).Using Investigation of Furrow Formation by Rotary Tillage Tools with an Active Drive a single-cell transcriptomic assay combined with genetic lineage tracing and live imaging, we find the FHF and SHF are subdivided into distinct pools of progen
