The mesoderm layer of the stem cell provides instructions for building the heart. Mesoderm cells migrate to form the cardiac crescent, which eventually develops into the heart tube and further into the mature heart during embryonic development.

The instructions for building the heart in an embryo are primarily located in the DNA within the cells of the embryo's mesoderm layer. This layer differentiates during development to form various structures, including the heart. Specific genes and signaling pathways, such as those involving the transcription factors NKX2-5 and GATA4, play crucial roles in heart development. Additionally, interactions with surrounding tissues help guide the proper formation and functioning of the heart.
