Somatic to iPS Cell Reprogramming01:29

Somatic to iPS Cell Reprogramming

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...

Methods of Nuclear Reprogramming

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...

Epigenetic Regulation

3.5K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Introduction to Nuclear Reprogramming

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...

Area of Science:

  • Epigenetics
  • Cellular Reprogramming
  • Biochemistry

Background:

  • Vitamin C (ascorbic acid) is a crucial cofactor for numerous enzymes.
  • Epigenetic modifications regulate gene expression without altering DNA sequence.
  • Somatic cell reprogramming aims to revert differentiated cells to a pluripotent state.

Discussion:

  • Vitamin C induces significant epigenetic remodeling in cells.
  • This remodeling facilitates the process of reprogramming somatic cells into induced pluripotent stem cells (iPSCs).
  • The study investigates the role of TET1 enzyme activity in this process.

Key Insights:

  • Vitamin C addition to cell culture medium enhances epigenetic reprogramming.
  • TET1 enzyme activity's effect on reprogramming efficiency is context-dependent.
  • Vitamin C presence or absence dictates whether TET1 inhibits or promotes reprogramming.

Outlook:

  • Understanding TET1's dual role could optimize iPSC generation protocols.
  • Further research may elucidate precise molecular mechanisms of vitamin C in epigenetics.
  • Potential applications in regenerative medicine and disease modeling.
