Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

3.9K
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).

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

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...

Regulation of Hematopoietic Stem Cells

3.1K
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...

EPS and iPS Cells in Disease Research

2.8K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Area of Science:

  • Hematology
  • Stem Cell Biology
  • Oncology

Background:

  • Myeloid malignancies are clonal disorders of hematopoietic stem and progenitor cells (HSPCs) driven by genetic alterations.
  • Induced pluripotent stem cells (iPSCs) can be differentiated into HSPCs, making them valuable for disease modeling and cell therapies.

Purpose of the Study:

  • To provide an overview of the rationale, challenges, and advances in using iPSC models for myeloid neoplasms.
  • To highlight insights into human oncogene function and cooperativity gained from iPSC models.

Main Methods:

  • Review of existing literature on iPSC models for myeloid malignancies.
  • Focus on genetic alterations, HSPC differentiation, and oncogene function.

Main Results:

  • iPSC models are increasingly used to study the origins and pathophysiology of myeloid malignancies.
  • These models reveal previously unknown aspects of human oncogene function and cooperativity.
  • iPSC models complement traditional methods using primary human cells.

Conclusions:

  • iPSC models are now a crucial tool for leukemia research.
  • They provide genetically defined systems to recapitulate leukemia development.
  • iPSC technology advances our understanding of myeloid neoplasm pathogenesis.
