Summary
Human embryonic stem cells offer therapeutic potential but can undergo epigenetic alterations during culture. Monitoring DNA methylation changes is crucial for their safe use in treating degenerative diseases.
Area of Science:
- Stem cell biology
- Epigenetics
- Developmental biology
Background:
- Human embryonic stem (ES) cells show promise for treating degenerative diseases.
- Culturing ES cells can lead to epigenetic changes affecting gene expression and phenotype.
Purpose of the Study:
- To discuss the maintenance of epigenetic information in stem cells and embryos.
- To explore how epigenetic stability influences the developmental potential of stem cells.
Main Methods:
- Review of recent studies on human and mouse stem cells.
- Analysis of epigenetic alterations, specifically DNA methylation.
- Examination of gene expression and phenotype changes.
Main Results:
- Developmental, cancer-related, and imprinted genes are susceptible to DNA methylation changes in cultured stem cells.
- Epigenetic instability, alongside genetic alterations, requires monitoring in human stem cells.
- Epigenetic information maintenance is key to stem cell developmental potential.
Conclusions:
- Epigenetic stability is a critical factor for the therapeutic application of human stem cells.
- Understanding epigenetic maintenance in stem cells and embryos is vital for their developmental potential.
- Monitoring epigenetic alterations is essential for the safe and effective use of stem cells in regenerative medicine.

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...
00:57Embryonic Stem Cells
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...

00:58Embryonic Stem Cells
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.
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...

01:27Source And Potency Of Stem Cells
Stem cells are undifferentiated cells with extensive self-renewal properties that help them maintain their population during the fetal and adult stages of life. They can specialize in all cell types of the human body. However, their differential potential may vary and can be classified into five types. Stem cells can be (1) Totipotent, (2) Pluripotent, (3) Multipotent, (4) Oligopotent, and (5) Unipotent. Each stem cell has a specific origin; the fertilized egg or zygote is a totipotent cell and...
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).
