Summary
Pluripotent stem cells (PS cells) possess self-renewal and differentiation capabilities. Epigenetic regulation and microRNAs are crucial for generating and maintaining these cells, offering insights into reprogramming and therapeutic applications.
Area of Science:
- Stem cell biology and epigenetics.
Background:
- Pluripotent stem (PS) cells, including embryonic stem cells and induced pluripotent stem cells, are key to regenerative medicine.
- Transcription factors and their epigenetic regulation are critical for PS cell generation, maintenance, and differentiation.
- Advanced sequencing technologies reveal unique epigenetic marks and microRNAs (miRs) associated with PS cells.
Purpose of the Study:
- To review recent advances in the epigenetics of pluripotent stem cells.
- To highlight the role of epigenetic modifications and miRs in regulating pluripotency.
- To underscore the importance of understanding these mechanisms for reprogramming and therapeutic applications.
Main Methods:
- This review synthesizes findings from recent studies on PS cell epigenetics.
- Analysis of epigenetic modifications such as histone modifications, DNA methylation, and chromatin remodeling.
- Investigation of the interplay between microRNAs and epigenetic modifiers in pluripotency.
Main Results:
- Epigenetic modifications, including histone modifications, DNA methylation, and chromatin remodeling, are fundamental to gene regulation in PS cells.
- MicroRNAs (miRs) work in concert with epigenetic modifiers to induce and maintain pluripotency.
- Dynamic epigenetic changes during reprogramming are increasingly understood in relation to cell fate determination.
Conclusions:
- Understanding the epigenetics of PS cells is vital for advancing reprogramming technologies and stem cell therapies.
- The interplay between epigenetic marks and miRs offers novel targets for enhancing reprogramming efficiency.
- Continued research into dynamic epigenetic changes will further elucidate cell fate mechanisms and unlock new therapeutic potentials.

01:32Chromatin Modification in iPS Cells
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...

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...
01:06Induced 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).

01:14Maintenance of the ES Cell State
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...
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...
