Somatic 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...

Liver Regeneration

5.0K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

Induced Pluripotent Stem Cells

28.6K
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...

Area of Science:

  • Regenerative Medicine
  • Cell Biology
  • Hepatology

Background:

  • Hepatocyte transplantation is a potential therapy for end-stage liver disease.
  • Limited availability of functional hepatocytes hinders clinical application.

Purpose of the Study:

  • To develop a simple, transient reprogramming method to convert fibroblasts into hepatic-like cells.
  • To assess the in vivo differentiation and functionality of these reprogrammed cells.

Main Methods:

  • Human skin fibroblasts were treated with fish egg extracts to create transiently remodeled cells (TRCs).
  • TRCs were infected with retroviral EGFP and injected into fetal monkey and mouse livers.
  • In situ differentiation and integration of TRCs were analyzed by assessing hepatic markers.

Main Results:

  • TRCs differentiated into functional hepatic-like cells in vivo, synthesizing albumin and cytokeratin-18.
  • These cells integrated into the liver parenchyma in both monkey and mouse models.
  • Reprogramming involved activation of signal pathways that reactivate endogenous cell potency genes.

Conclusions:

  • A simple, inexpensive epigenetic remodeling approach can convert human fibroblasts into therapeutic hepatic-like cells.
  • This method shows feasibility for treating end-stage liver disease.
