Summary
Understanding platelet biogenesis (thrombopoiesis) is key for treating blood disorders. This review explores in vivo and in vitro methods for generating platelets, highlighting current challenges and future directions.
Area of Science:
- Hematology
- Cell Biology
- Biotechnology
Background:
- Platelets are vital for hemostasis, thrombosis, and immunity.
- The intricate process of platelet biogenesis, or thrombopoiesis, remains incompletely understood.
- Gaining deeper insight is crucial for managing hematological disorders and developing cell-based therapies.
Purpose of the Study:
- To review the current understanding of in vivo thrombopoiesis.
- To discuss the progress and limitations of in vitro platelet generation systems.
- To identify key challenges and controversies in the field.
Main Methods:
- Review of in vivo mechanisms of platelet generation from megakaryocytes (proplatelet formation, cytoplasmic fragmentation, membrane budding).
- Analysis of physiological locations of platelet production.
- Evaluation of current in vitro platelet generation systems for therapeutic applications.
Main Results:
- Detailed mechanisms of in vivo platelet formation are presented.
- Progress in replicating thrombopoiesis in vitro for therapeutic use (e.g., platelet transfusion, bioengineered platelets) is discussed.
- Limitations of current in vitro systems, including yield, scalability, and functionality, are highlighted.
Conclusions:
- A comprehensive understanding of both in vivo and in vitro thrombopoiesis is essential.
- Further research is needed to address current controversies and challenges.
- Advancements in platelet generation hold promise for novel therapeutic strategies.

The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
