Summary
This study details using piggyBac (PB) transposons for efficient generation of induced pluripotent stem cells (iPSCs) from mouse somatic cells. PB transposons are crucial tools for dissecting the cellular and molecular mechanisms of reprogramming.
Area of Science:
- Stem cell biology
- Genomics
- Molecular biology
Background:
- Induced pluripotent stem cells (iPSCs) offer revolutionary potential for regenerative medicine and functional genomics.
- The underlying mechanisms of somatic cell reprogramming remain incompletely understood.
- Transgenic tools are essential for elucidating these complex cellular transformations.
Purpose of the Study:
- To provide a comprehensive overview of generating iPSCs from mouse somatic cells using piggyBac (PB) transposons.
- To describe the establishment of secondary reprogramming systems.
- To highlight the utility of PB transposons in dissecting reprogramming processes.
Main Methods:
- Utilizing piggyBac (PB) transposons for the delivery of reprogramming factors to mouse somatic cells.
- Establishing primary iPSC generation protocols.

01:24Methods of Nuclear Reprogramming
2.3K
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...

01:29Somatic to iPS Cell Reprogramming
2.9K
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...

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
