Summary
MLL5, a potential tumor suppressor, is crucial for blood cell development. Its absence in mice led to significant hematopoietic defects, underscoring its role in hematopoietic stem cells.
Area of Science:
- Hematology
- Molecular Biology
- Genetics
Background:
- MLL5 is an MLL family protein and a candidate tumor suppressor.
- MLL5 is located at human chromosome band 7q22, a region frequently deleted in myeloid malignancies.
Discussion:
- Three independent studies report the first genetic analysis of MLL5 deficiency in mice.
- All three MLL5 knockout mouse strains exhibited defects in hematopoiesis.
Key Insights:
- MLL5 plays a critical role in hematopoietic stem cell functions.
- MLL5 deficiency impacts the development of blood cells.
Outlook:
- Further research into MLL5's function could reveal new therapeutic targets for myeloid malignancies.
- Understanding MLL5's role in hematopoiesis is essential for advancing stem cell biology.

Regulation of Hematopoietic Stem Cells
All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...
Hematopoiesis
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...
Multipotency 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...
Overview 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...

Role of Hematopoietic Growth Factors
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
