Summary
Leukemia thrives by exploiting the bone marrow microenvironment, disrupting normal blood cell formation (hematopoiesis). This chapter details the niche
Area of Science:
- Hematology
- Oncology
- Cell Biology
Background:
- The human body needs continuous blood cell production (hematopoiesis) for homeostasis.
- Leukemia disrupts this process by hijacking the bone marrow microenvironment.
Purpose of the Study:
- To characterize the bone marrow niche and its role in leukemia expansion.
- To explore interactions between leukemic cells and the niche.
- To discuss novel therapeutic strategies targeting this interaction.
Main Methods:
- Review of bone marrow microenvironment components.
- Analysis of cellular interactions in leukemia.
- Discussion of therapeutic targets within the niche.
Main Results:
- The bone marrow niche is crucial for leukemia growth and survival.
- Specific interactions between leukemic cells and niche components are identified.
- Cellular pathways within malignant cells are activated by the niche.
Conclusions:
- Understanding the bone marrow microenvironment is key to combating leukemia.
- Targeting the leukemia-niche interaction offers promising therapeutic avenues.

The Tumor Microenvironment
7.5K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Stem Cell Niche
6.0K
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...

Tumor Progression
7.1K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer Stem Cells and Tumor Maintenance
5.8K
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.

Differentiation of Common Myeloid Progenitor Cells
3.8K
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...

Adaptive Mechanisms in Cancer Cells
6.8K
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.
