microRNAs as novel regulators of stem cell pluripotency and somatic cell reprogramming
1Division of Cellular and Developmental Biology, Molecular and Cell Biology Department, University of California at Berkeley, Berkeley, CA, USA.
Summary
MicroRNAs (miRNAs) are crucial regulators of embryonic stem cell pluripotency and somatic cell reprogramming. Understanding miRNA gene regulation offers new insights into stem cell biology and therapeutic potential.
Area of Science:
- Stem cell biology
- Gene regulation
- Epigenetics
Background:
- MicroRNAs (miRNAs) are key post-transcriptional regulators.
- Embryonic stem (ES) cell pluripotency, differentiation, and reprogramming involve miRNAs.
- Specific miRNA clusters (e.g., miR-290, miR-302) are enriched in ES cells, while others (e.g., let-7) are depleted.
Purpose of the Study:
- To explore the role of miRNA-mediated gene regulation in ES cell pluripotency and somatic cell reprogramming.
- To understand how miRNAs target diverse cellular processes to influence cell fate.
- To investigate the regulation of miRNA transcription and biogenesis.
Main Methods:
- Analysis of ES cell-enriched and -depleted miRNAs.
- Investigating miRNA targets in cell cycle, signaling pathways, transcription factors, and epigenetic modifiers.
- Examining the combinatorial effects of miRNA actions.
Main Results:
- miRNAs modulate protein output by targeting key cellular regulators.
- miRNAs effectively influence cell-fate decisions through combinatorial effects.
- Both miRNA transcription and biogenesis are tightly regulated processes.
Conclusions:
- miRNAs play a critical role in maintaining pluripotency and driving reprogramming.
- Understanding miRNA regulatory networks is essential for stem cell biology.
- Further research into the interplay of miRNAs and gene regulation will advance stem cell therapies.

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.
01:06Induced 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).

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...

01:32Chromatin 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...
