Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

3.3K
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...

Differentiation of Common Myeloid Progenitor Cells

3.3K
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 Leukocytes01:27

Disorders of Leukocytes

1.1K
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...

lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

8.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

  • Molecular Biology

Background:

  • Acute myeloid leukemia (AML) is a blood cancer originating from defective bone marrow stem cells.
  • Despite new targeted therapies, AML recurrence remains a significant clinical challenge.

Main Methods:

  • Literature review focusing on AML pathogenesis and bone marrow niche interactions.
  • Analysis of studies investigating the role of circRNAs in hematological malignancies.
  • Synthesis of current understanding of cell-cell communication in the leukemic niche.

Main Results:

  • AML progression involves significant remodeling of the bone marrow niche.
  • Complex interactions between AML cells and the microenvironment impact treatment outcomes.
  • Circular RNAs emerge as key mediators of cell communication and chemoresistance in AML.
