Summary
Pluripotent stem cells maintain self-renewal and differentiation potential. Transcription factors precisely balance pluripotency networks, influencing cell fate decisions and controlled differentiation into specific lineages.
Area of Science:
- Stem cell biology
- Developmental biology
- Molecular genetics
Background:
- Pluripotent stem cells (PSCs) self-renew and differentiate into three germ layers.
- Established knowledge exists on pluripotency maintenance and differentiation regulators.
- Pluripotency exhibits varying potentials, including a 'ground state'.
Purpose of the Study:
- To summarize recent findings on transcription factor roles in PSC pluripotency.
- To discuss mechanisms governing the controlled exit from pluripotency.
- To elucidate how transcription factors orchestrate cell fate decisions.
Main Methods:
- Review of recent literature on pluripotency regulation.
- Analysis of signaling axes and transcription factor interplay.
- Investigation of gene expression patterns in lineage specification.
Main Results:
- Transcription factor balance is critical for pluripotency network integrity.
- Minute expression changes can strengthen or collapse the network.
- Pluripotency factors adopt new roles in lineage specification (neuroectodermal, mesendodermal).
Conclusions:
- Complex interactions regulate the controlled exit from pluripotency.
- Transcription factors are key orchestrators of cell fate decisions.
- Further research is needed to fully understand these underlying mechanisms.

01:29Somatic to iPS Cell Reprogramming
2.8K
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...

01:27Source And Potency Of Stem Cells
6.8K
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...

01:24Methods of Nuclear Reprogramming
2.2K
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...

01:14Maintenance of the ES Cell State
2.8K
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...

01:32Chromatin Modification in iPS Cells
2.3K
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...
