Introduction

The embryo stage 10 heart tube

Development of the heart and vascular system begins very early in mesoderm both within (embryonic) and outside (extra embryonic, yolk sac and placental) the embryo. Vascular development therefore occurs in many places, the most obvious though is the early forming heart, which grows rapidly creating an externally obvious cardiac "bulge" on the early embryo. The cardiovascular system is extensively remodelled throughout development, this current page only introduces topic.

The heart forms initially in the embryonic disc as a simple paired tube inside the forming pericardial cavity, which when the disc folds, gets carried into the correct anatomical position in the chest cavity.

Throughout the mesoderm, small regions differentiate into "blood islands" which contribute both blood vessels (walls) and fetal red blood cells.

These "islands" connect together to form the first vessels which connect with the heart tube.


A detailed description of heart development is covered in the Online Heart Tutorial.

Some Recent Findings

  • Assembly of the Cardiac Intercalated Disk during Pre- and Postnatal Development of the Human Heart[1] "In cardiac muscle, the intercalated disk (ID) at the longitudinal cell-edges of cardiomyocytes provides as a macromolecular infrastructure that integrates mechanical and electrical coupling within the heart. ...Our data on developmental maturation of the ID in human heart indicate that generation of the mechanical junctions at the ID precedes that of the electrical junctions with a significant difference in time. In addition arrival of the electrical junctions (Nav1.5 and Cx43) is not uniform since sodium channels localize much earlier than gap junction channels."
  • Endothelial cell lineages of the heart. [2] "During early gastrulation, vertebrate embryos begin to produce endothelial cells (ECs) from the mesoderm. ECs first form primitive vascular plexus de novo and later differentiate into arterial, venous, capillary, and lymphatic ECs. In the heart, the five distinct EC types (endocardial, coronary arterial, venous, capillary, and lymphatic) have distinct phenotypes. For example, coronary ECs establish a typical vessel network throughout the myocardium, whereas endocardial ECs form a large epithelial sheet with no angiogenic sprouting into the myocardium. Neither coronary arteries, veins, and capillaries, nor lymphatic vessels fuse with the endocardium or open to the heart chamber. The developmental stage during which the specific phenotype of each cardiac EC type is determined remains unclear. The mechanisms involved in EC commitment and diversity can however be more precisely defined by tracking the migratory patterns and lineage decisions of the precursors of cardiac ECs."

The Human Heart from day 10 to 25 (scanning electron micrograph)
  • Forms initially in splanchnic mesoderm of prechordal plate region - cardiogenic region
    • growth and folding of the embryo moves heart ventrally and downward into anatomical position
  • Day 22 - 23, begins to beat in humans
    • heart tube connects to blood vessels forming in splanchnic and extraembryonic mesoderm
  • Week 2 - 3 pair of thin-walled tubes
  • Week 3 paired heart tubes fuse, truncus arteriosus outflow, heart contracting
  • Week 4 heart tube continues to elongate, curving to form S shape
  • Week 5 Septation starts]], atrial and ventricular
    • Septation continues, atrial septa remains open, foramen ovale
  • Week 37-38 At birth, pressure difference closes foramen ovale leaving a fossa ovalis

Pharyngeal Arch Arteries

Pharyngeal arch arteries

In the head region of the embryo, each pharyngeal arch initially has paired arch arteries. These are extensively remodelled through development and give rise to a range of different arterial structures, as shown in the list below.

  • Arch 1 - mainly lost, form part of maxillary artery.
  • Arch 2 - stapedial arteries.
  • Arch 3 - common carotid arteries, internal carotid arteries.
  • Arch 4 - left forms part of aortic arch, right forms part right subclavian artery.
  • Arch 6 - left forms part of left pulmonary artery , right forms part of right pulmonary artery.

Renal Venous Development

The renal arterial and venous systems are also reorganised extensively throughout development with changing kidney position.
