Study Notes
Development of the Vascular System
- The vascular system appears in the embryo during the third week of development.
Development of the Heart
- The heart starts pumping blood in human embryos around 3-4 weeks after fertilization.
Origins of Cardiac Progenitor Cells
- Cardiac progenitor cells are derived from the lateral plate mesoderm.
Cardiogenic Cells
- The first source for cardiogenic cells is known as the cardiogenic plate.
- The central portion of the cardiogenic area is initially located in the anterior medial region of the embryo.
