Summary
The placenta is a source of hematopoietic stem and progenitor cells in both mice and humans. This finding opens new avenues for understanding blood formation during development and has clinical implications.
Area of Science:
- Developmental biology
- Hematopoiesis
- Reproductive biology
Background:
- The placenta's role in fetal development is well-established.
- Recent findings suggest the placenta harbors hematopoietic stem and progenitor cells.
- This challenges traditional views of hematopoietic organ development.
Purpose of the Study:
- To investigate placental hematopoiesis in mice and humans.
- To determine if the human placenta supports hematopoietic stem and progenitor cell expansion.
- To understand the significance of multiple hematopoietic organs during development.
Main Methods:
- Review of current knowledge on murine placental hematopoiesis.
- Presentation of new data on human placental hematopoietic stem and progenitor cells.
- Comparative analysis of placental hematopoietic capacity.
Main Results:
- Murine placenta supports hematopoietic stem and progenitor cell expansion.
- Human placenta also serves as a source of hematopoietic stem and progenitor cells.
- These cells are present throughout human placental development.
Conclusions:
- The placenta is a significant hematopoietic organ in both mice and humans.
- Understanding placental hematopoiesis is crucial for developmental and clinical research.
- This research revisits fundamental questions about early blood formation.

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...

01:20Overview of Hematopoiesis
Hematopoiesis, or blood cell production, is a vital biological process that begins early in embryonic development and continues throughout life. This process generates the various types of cells found in blood, including red blood cells, white blood cells, and platelets from hematopoietic stem cells (HSCs).
Developmental Phases of Hematopoiesis
Initially, HSCs are formed in the embryonic yolk sac, a critical site for early blood cell production. These stem cells subsequently migrate to other...

01:21Hematopoiesis
The process of blood cell formation is called hematopoiesis. Hematopoiesis starts early during development, on the seventh day of embryogenesis. This phase of hematopoiesis is called the primitive wave, wherein the extraembryonic yolk sac allows the production of erythroid cells and endothelial cells from a common precursor called hemangioblast. The erythroid cells provide oxygen to support the growth of the rapidly dividing embryo. Hemangioblasts later develop into hematopoietic stem cells or...
01:19Multipotency of Hematopoietic Stem Cells
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...
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...

01:34Production of Formed Elements
Hemangioblasts are multipotent stem cells originating from the mesoderm. They give rise to hematopoietic stem cells (HSCs), which undergo hematopoiesis to produce all the formed elements of blood. This process is regulated by a complex network of hematopoietic growth factors, including transcription factors, growth factors, and cytokines. These factors stimulate the HSCs to divide and differentiate, though some HSCs remain undifferentiated to maintain a self-renewing pool.
