Stem Cell Plasticity and Niche Dynamics in Cancer Progression
IEEE Transactions on Bio-Medical Engineering
|January 24, 2017
Summary
Cancer stem cells (CSCs) are not solely responsible for tumor growth. Environmental factors, not just genetics, can drive cancer development and offer new therapeutic targets.
Area of Science:
- Computational biology
- Cancer research
- Cellular dynamics
Background:
- Cancer stem cells (CSCs) are hypothesized to drive tumor growth and recurrence.
- Recent evidence suggests stemness is influenced by the cellular microenvironment.
- Understanding stemness plasticity could lead to novel therapeutic strategies.
Purpose of the Study:
- Investigate the role of environmental context in stem-like cell properties.
- Simulate ductal carcinoma using in-silico models.
- Explore interactions between cancer cells and their dynamic environment.
Main Methods:
- Developed a 2D hybrid discrete-continuum cellular automata model.
- Simulated single-cell dynamics in multicellular tissue formation.
- Analyzed interactions within a heterogeneous cancer cell population and dynamic environment.
Main Results:
- Generated homeostatic ductal structures with stem and differentiated cells.
- Demonstrated that microenvironmental variations can produce diverse tumor-like histologies.
- Showcased niche-driven phenotypic plasticity as an explanation for observed ductal structures.
Conclusions:
- Niche-driven phenotypic plasticity explains diverse ductal structures in breast cancer.
- Environmental variations can induce intraductal cancers independently of genetic changes.
- Targeting the microenvironment may offer alternative cancer prevention strategies.

01:26Stem Cell Niche
6.5K
The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

02:40Cancer Stem Cells and Tumor Maintenance
6.2K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.

01:19Multipotency of Hematopoietic Stem Cells
4.0K
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...

02:53Adaptive Mechanisms in Cancer Cells
7.2K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.

01:29Somatic to iPS Cell Reprogramming
2.8K
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...

01:06Multipotency and Niche of Bulge Stem Cell
4.3K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
