Summary
This review details blood vessel formation in the first trimester human placenta, covering vasculogenesis and angiogenesis. It highlights key cellular players and growth factors involved in placental vascular development.
Area of Science:
- Embryology
- Developmental Biology
- Vascular Biology
Background:
- Vasculogenesis and angiogenesis are critical for human placental blood vessel formation.
- These processes are essential for nutrient and gas exchange between mother and fetus.
Purpose of the Study:
- To provide an overview of vasculogenesis and angiogenesis during the first trimester of human placental development.
- To highlight the molecular and morphological aspects of early placental vascularization.
Main Methods:
- Review of recent scientific literature on human placental development.
- Analysis of cellular and molecular mechanisms driving vasculogenesis and angiogenesis.
Main Results:
- Cytotrophoblasts initiate vasculogenesis and angiogenesis in early placental development.
- Hofbauer and stromal cells assume control of vascular development later in pregnancy.
- Vascular Endothelial Growth Factor (VEGF) family, its receptors, Tie-1, and Tie-2 are key regulators.
Conclusions:
- Understanding these processes offers insights into placental development and maturation disorders.
- Early placental vascularization involves dynamic cellular contributions and signaling pathways.

01:07Development of Blood Vessels
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

01:10Mechanism of Angiogenesis
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
01:24Regulation of Angiogenesis and Blood Supply
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
