Summary
Multiple Coagulation Factor Deficiency Protein 2 (MCFD2) maintains stem cell pluripotency, similar to FGF-2. This conserved protein
Area of Science:
- Stem cell biology
- Molecular biology
- Developmental biology
Background:
- Multiple Coagulation Factor Deficiency Protein 2 (MCFD2) defects cause Factor V and Factor VIII combined deficiency type 2 (F5F8D).
- MCFD2 is implicated in maintaining neural stem cell potential.
- Understanding MCFD2's role in stem cell maintenance is crucial.
Purpose of the Study:
- To investigate the role of MCFD2 in maintaining stem cell pluripotency.
- To compare MCFD2's effects with basic fibroblast growth factor 2 (FGF-2) in rhesus monkey embryonic stem cells (rESCs).
- To elucidate the molecular mechanisms underlying MCFD2's function in stemness.
Main Methods:
- Treatment of rESCs with amphibian and human MCFD2.
- Comparative analysis with FGF-2 treatment.
- Investigation of signaling pathways (MAPK, TGF-β, Wnt, Akt) and core transcriptional factors (Oct4, Nanog, Sox2).
Main Results:
- Both amphibian and human MCFD2 maintain rESC pluripotency, mirroring FGF-2 effects.
- MCFD2 and FGF-2 exhibit similar impacts on stem cell markers and signaling pathways.
- Primate ESCs display unique signaling pathway features compared to human and mouse ESCs.
Conclusions:
- MCFD2 is a key factor in maintaining stem cell pluripotency and self-renewal.
- The conserved protein family, including MCFD2, likely shares the general function of supporting stem cell self-renewal.
- Primate ESCs possess distinct signaling mechanisms that warrant further investigation.

01:01Regulation 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...
01:28Role 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.

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...
01:15Differentiation of Common Myeloid Progenitor Cells
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
01:14Maintenance of the ES Cell State
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...
01:27Molecular Factors Affecting Cell Division
Several external and internal factors influence the initiation and inhibition of cell division. For instance, the death of nearby cells or the release of human growth hormone (hGH) promotes cell division. In contrast, lack of hGH or crowding of cells can inhibit cell division.
Several proteins function as internal regulators to ensure each cell cycle stage is completed faithfully before proceeding to the next. Regulator molecules may act directly or influence the activity or production of other...
