Summary
Embryonic stem cells maintain pluripotency through epigenetic regulation and chromatin structure. High-throughput technologies offer new insights into these mechanisms, crucial for development and cell fate.
Area of Science:
- Developmental Biology
- Epigenetics
- Stem Cell Biology
Background:
- Embryonic stem cells (ESCs) possess unique self-renewal and differentiation capabilities.
- Pluripotency in ESCs is governed by transcriptional regulation, epigenetic modifications, and chromatin structures.
- Epigenetic regulation involves covalent histone modifications like methylation, phosphorylation, and acetylation.
Purpose of the Study:
- To summarize recent advances in profiling epigenetic modifications and chromatin structures in ESCs.
- To highlight the role of genome-wide analysis of histone modifications in maintaining ESC pluripotency.
Main Methods:
- Utilizing high-throughput technologies for global, unbiased profiling.
- Analyzing epigenetic modifications and chromatin conformations.
- Focusing on genome-wide histone modification analysis.
Main Results:
- Recent technological progress allows comprehensive views of epigenetic landscapes in ESCs.
- These landscapes are critical for gene expression regulation and cell identity.
- Histone modifications play a key role in ESC pluripotency.
Conclusions:
- Epigenetic modifications and chromatin structures are central to ESC pluripotency.
- High-throughput approaches provide powerful tools for studying these mechanisms.
- Understanding these processes is vital for developmental biology and stem cell research.

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...

01:14Maintenance 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...
01:24Methods of Nuclear Reprogramming
Nuclear reprogramming is a process of transforming one cell type into an unrelated cell type by epigenetic changes that alter the cell’s original gene expression pattern. Such epigenetic changes force cells to express a different set of genes, which play a significant role in inducing transformation into other cell types. Nuclear reprogramming offers applications in reproductive cloning for livestock propagation and regenerative medicine — developing patient-specific cells for injury repair.
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...
