Stem Cell Culture

Stem Cell Culture

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...

iPS Cell Differentiation

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Induced Pluripotent Stem Cells

Induced 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...

Induced Pluripotent Stem Cells

Induced 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).

Stem Cell Therapy for Tissue Regeneration

Stem Cell Therapy for Tissue Regeneration

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Liver Regeneration

Liver Regeneration

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 large...

Summary

Researchers are exploring extra-hepatic pluripotent stem cells (PSCs) for liver disease therapies. Identifying these PSCs and understanding their differentiation potential could reduce the need for liver transplantation.

Area of Science:

Stem cell biology
Hepatology
Regenerative medicine

Background:

Hepatic progenitor cells are found in extra-hepatic tissues in humans and animal models.
Understanding liver stem cell pathobiology is crucial for regeneration and hepatocarcinogenesis research.
Current liver disease therapies often require transplantation.

Purpose of the Study:

To identify accessible pluripotent stem cell (PSC) sources for cell-based therapies.
To evaluate the potential of PSCs for treating genetic and acquired liver diseases.
To review current research on PSCs in hepatic and extra-hepatic tissues.

Main Methods:

Investigating the presence of PSCs in various tissue locations.
Assessing the in vitro differentiation capacity of PSCs.
Evaluating the in vivo liver function restoration by PSCs.

Main Results:

Several sources of hepatic progenitors have been identified in extra-hepatic locations.
Microenvironment factors influencing liver cell precursor proliferation and commitment are being characterized.
Research is ongoing to evaluate PSC differentiation and liver function restoration.

Conclusions:

Extra-hepatic PSCs offer promising avenues for novel liver disease therapies.
Further characterization of PSCs and their microenvironment is essential for therapeutic development.
Cell-based therapies using PSCs could potentially reduce reliance on liver transplantation.
