Summary
Epigenetic modifications, including DNA methylation and histone changes, are crucial for stem cell reprogramming and differentiation. Understanding these epigenetic events is key to improving stem cell therapies and ensuring consistent results.
Area of Science:
- Epigenetics and Stem Cell Biology
- Molecular Biology
- Cellular Reprogramming
Background:
- Epigenetic modifications orchestrate global transcriptome changes, influencing gene expression.
- Reprogramming somatic cells to induced pluripotent stem (iPS) cells exemplifies epigenetic modifications.
- Epigenetics dictates cell fates during stem cell differentiation.
Purpose of the Study:
- To provide a simplified overview of epigenetics in stem cells.
- To highlight the impact of epigenetic changes on gene expression and stem cell behavior.
- To compare epigenetic status in iPS and embryonic stem (ES) cells.
Main Methods:
- Review of dominant epigenetic changes (histone modifications, DNA methylation, chromatin remodeling).
- Analysis of impacts on global gene expression.
- Comparison of epigenetic profiles between iPS and ES cells.
Main Results:
- Epigenetic modifications are central to stem cell reprogramming and differentiation.
- Inconsistencies in stem cell reprogramming necessitate further investigation into epigenetic roles.
- Subtle epigenetic differences exist between iPS cells and between iPS and ES cells.
Conclusions:
- Epigenetic modifications significantly impact stem cell generation, maintenance, and function.
- Key epigenetic issues like X-chromosome reactivation and loss of imprinting affect iPS cell generation.
- Further research into epigenetics is vital for advancing stem cell applications, including cell therapy.

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).

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

01:37Epigenetic Regulation
3.9K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
