Summary
Mesenchymal stem cells (MSCs) can transform into aggressive sarcomas due to oncogenic fusion proteins. Targeting epigenetic changes with differentiation therapies may offer a promising new sarcoma treatment.
Area of Science:
- Oncology
- Stem Cell Biology
- Epigenetics
Background:
- Mesenchymal stem cells (MSCs) are multipotent cells that can differentiate into various connective tissues.
- Transformed MSCs can develop into aggressive sarcomas, often driven by specific chromosomal translocations.
- These translocations generate fusion proteins with oncogenic properties, leading to aberrant MSC reprogramming.
Purpose of the Study:
- To investigate the role of aberrant reprogramming in sarcoma pathogenesis.
- To explore the potential of targeting epigenetic modifications in sarcoma therapy.
Main Methods:
- Analysis of sarcoma oncogenes and their impact on MSCs.
- Examination of lineage-specific transcription factors and chromatin structure controllers.
- Evaluation of differentiation-related reagents for therapeutic potential.
Main Results:
- Sarcoma oncogenes reprogram MSCs, committing them to a lineage but blocking differentiation.
- Deregulated transcription factors and chromatin controllers are central to MSC reprogramming and sarcoma development.
- Epigenetic aberrations induced by sarcoma oncogenes are key to disease progression.
Conclusions:
- Reversing epigenetic aberrancies in MSCs is a potential therapeutic strategy for sarcomas.
- Differentiation-related reagents show promise for enhancing sarcoma treatments by correcting epigenetic errors.

2.0K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

01:06Induced Pluripotent Stem Cells
4.8K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

01:24Methods of Nuclear Reprogramming
1.4K
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for...

01:14Introduction to Nuclear Reprogramming
1.3K
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

01:33Cancer-Critical Genes I: Proto-oncogenes
8.9K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
