Summary
Induced pluripotent stem cells (iPSCs) offer regenerative medicine potential but harbor genetic and epigenetic variations. This review examines iPSC variations, their origins, implications, and strategies to manage them for therapeutic use.
Area of Science:
- Stem cell biology
- Regenerative medicine
- Epigenetics
Background:
- Induced pluripotent stem cells (iPSCs) are derived from somatic cells, offering a promising avenue for regenerative medicine.
- Recent research highlights genetic and epigenetic variations within iPSCs, raising concerns about their clinical applicability.
Purpose of the Study:
- To review the current understanding of genetic and epigenetic variations in iPSCs.
- To identify the causes and implications of these variations for iPSC-based therapies.
- To propose strategies for managing iPSC variations.
Main Methods:
- Literature review of studies on iPSC genetic and epigenetic variations.
- Analysis of the origins and functional consequences of these variations.
- Synthesis of current knowledge and proposed future directions.
Main Results:
- iPSCs exhibit diverse genetic and epigenetic alterations compared to their cells of origin and embryonic stem cells.
- These variations can arise during reprogramming or subsequent culture.
- The implications of these variations range from altered differentiation potential to tumorigenicity.
Conclusions:
- Genetic and epigenetic variations in iPSCs pose significant challenges for their safe and effective use in regenerative medicine.
- Understanding the mechanisms driving these variations is crucial for developing robust quality control measures.
- Strategies to minimize, detect, and manage iPSC variations are essential for advancing iPSC technology.

01:06Induced Pluripotent Stem Cells
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).

01:13Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore called induced pluripotent stem...

01:22iPS 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.
01:21EPS and iPS Cells in Disease Research
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,...
01:29Somatic to iPS Cell Reprogramming
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 for this...
