Summary
High-quality induced pluripotent stem cells (iPSCs) are crucial for regenerative medicine. New research shows H2A.X deposition acts as an epigenetic marker to identify superior iPSC lines, improving reprogramming methods.
Area of Science:
- Stem cell biology
- Epigenetics
- Regenerative medicine
Background:
- Induced pluripotent stem cells (iPSCs) are vital for regenerative medicine.
- Defining and obtaining high-quality iPSC lines remains a challenge.
- Current methods for assessing iPSC quality need improvement.
Purpose of the Study:
- To identify a reliable marker for distinguishing iPSC quality.
- To provide insights into improving cellular reprogramming methods.
- To establish functional epigenetic markers for iPSC assessment.
Main Methods:
- Investigated H2A.X deposition as a potential epigenetic marker.
- Compared H2A.X levels in iPSCs of varying quality.
- Utilized functional assays to validate marker efficacy.
Main Results:
- H2A.X deposition was identified as a functional epigenetic marker.
- The level of H2A.X deposition correlates with iPSC quality.
- This marker aids in differentiating high-quality iPSC lines.
Conclusions:
- H2A.X deposition offers a novel method for assessing iPSC quality.

Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

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...

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).

1.9K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

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.
