Summary
Mammalian pluripotent stem cells exhibit dynamic changes in developmental potential during early development. These stem cells show significant plasticity in culture, influenced by external signals, which is crucial for future research and therapies.
Area of Science:
- Developmental biology
- Stem cell biology
- Genetics
Background:
- Pluripotent cells during mammalian development undergo stepwise restriction of potential.
- Key regulatory gene expression changes accompany these developmental transitions.
- Cultured stem cell lines can model these developmental transition states.
Purpose of the Study:
- To investigate the heterogeneity and plasticity of pluripotent stem cell populations in vitro.
- To understand the role of extrinsic signaling in modulating stem cell plasticity.
- To inform the use of human pluripotent stem cells in research and therapy.
Main Methods:
- Utilized cultured stem cell lines derived from different stages of mouse development.
- Observed transition states mimicking early mammalian development.
- Analyzed heterogeneity and plasticity within pluripotent populations.
- Investigated modulation of plasticity by extrinsic signaling.
Main Results:
- Cultured stem cell lines successfully mimicked developmental transition states.
- Pluripotent populations in vitro demonstrated significant heterogeneity and plasticity.
- Extrinsic signaling was identified as a modulator of stem cell plasticity.
Conclusions:
- Stem cell plasticity in vitro reflects developmental transitions.
- Understanding extrinsic control of plasticity is key for stem cell applications.
- This knowledge will advance human pluripotent stem cell research and therapeutic strategies.

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...
01:32Chromatin 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).
