Summary
Induced pluripotent stem cells (iPSCs) offer a revolutionary alternative to embryonic stem cells (ESCs). These reprogrammed cells are autologous and bypass ethical concerns, holding promise for regenerative medicine.
Area of Science:
- Stem cell biology
- Reproductive biology
- Biotechnology
Background:
- Embryonic stem cells (ESCs) are ethically controversial and not patient-specific.
- Induced pluripotent stem cells (iPSCs) are generated from adult somatic cells.
- iPSCs possess pluripotency and self-renewal capabilities similar to ESCs.
Purpose of the Study:
- To review the advent and principles of iPSC technology.
- To discuss the potential applications of iPSCs in surgical research and regenerative medicine.
Main Methods:
- Exogenous expression of defined transcription factors in somatic cells.
- Nuclear reprogramming techniques to induce pluripotency.
- Comparative analysis of iPSCs and ESCs.
Main Results:
- iPSCs exhibit self-renewal and multipotency comparable to ESCs.
- iPSCs are autologous, circumventing immune rejection.
- iPSC generation avoids ethical issues associated with ESCs.
Conclusions:
- iPSC technology represents a significant advancement in stem cell research.
- iPSCs offer a promising, ethically sound alternative to ESCs.
- The potential applications of iPSCs in regenerative medicine and surgery are vast.

1.4K
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...

1.3K
Nuclear reprogramming is the process of switching gene expression of one cell type to that of another cell type, usually from a differentiated cell state to an undifferentiated cell state. Differentiation occurs during processes such as development and morphogenesis, tissue regeneration, and malignancy. Cells can also be artificially induced to reprogram their gene expression by techniques such as nuclear transfer, induced pluripotency, and cell fusion. Such techniques have many applications in...

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).

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...

2.1K
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...
