Bone marrow neoplastic niche in leukemia
Hematology (Amsterdam, Netherlands)
|August 3, 2013
Summary
The leukemic niche, a microenvironment supporting cancer growth, involves malignant stem cells and signaling pathways. Understanding these interactions, including microRNAs, is key to developing effective leukemia treatments and overcoming drug resistance.
Area of Science:
- Hematology
- Oncology
- Cell Biology
Background:
- The neoplastic niche provides a specific microenvironment crucial for malignant cell growth and proliferation.
- Understanding the leukemic niche is essential for comprehending leukemia pathogenesis.
Purpose of the Study:
- To review the leukemic niche, including its constituent stem cells, signaling pathways, and key chemokines.
- To highlight the role of microRNAs in regulating gene expression within the leukemic niche.
Main Methods:
- A comprehensive literature search was conducted using PubMed.
- Keywords included 'neoplastic niche,' 'chemokines,' and 'leukemia.'
- The search focused on English-language literature published between 2000 and 2013.
Main Results:
- Leukemia arises from malignant hematopoietic stem cells and precursors.
- Interactions between leukemic cells and their microenvironment involve critical molecules and signaling pathways.
- MicroRNAs (miRNAs) significantly regulate oncogenes, transcription factors, and signaling molecules, influencing cell fate.
Conclusions:
- Aberrant miRNA expression in the bone marrow niche warrants further investigation for its role in malignant transformation.
- Characterizing leukemic cells, signaling pathways, and disease progression molecules is vital for understanding drug resistance and relapse.
- This knowledge will facilitate the development of more effective leukemia treatments.

Stem Cell Niche
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...
Differentiation 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...
Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune system...

Bone Marrow Sampling and Transplants
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.

Stem Cell Therapy for Tissue Regeneration
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

The Tumor Microenvironment
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...
