Maintenance of the ES Cell State

Maintenance of the ES Cell State

The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

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.

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...

Forced Transdifferentiation

Forced Transdifferentiation

Transdifferentiation, also known as lineage reprogramming, was first discovered by Selman and Kafatos in 1974 in silkmoths. They observed that the moths’ cuticle-producing cells transformed into salt-producing cells. Many such cases of natural transdifferentiation occur in organisms. In humans, pancreatic alpha cells can become beta cells. In newts, the loss of the eye’s lens causes the pigmented epithelial cells to transdifferentiate into the lens cells.
Artificial transdifferentiation occurs...

Area of Science:

Biomedical Engineering
Cell Biology
Mechanobiology

Background:

Chemical and biological factors are traditionally studied for stem cell differentiation.
Emerging evidence highlights the critical role of mechanical cues in stem cell fate.
Physical properties of the cellular environment significantly impact stem cell behavior.

Purpose of the Study:

To review experimental studies on stem cell responses to mechanical and geometrical environmental properties.
To discuss the underlying mechanical mechanisms driving stem cell differentiation.
To consolidate current understanding of mechanotransduction in stem cells.

Main Methods:

Survey of experimental literature on stem cell responses to mechanical stimuli.
Analysis of studies investigating substrate rigidity and topography effects.
Review of research on cellular mechanical responses, including cytoskeleton remodeling.

Main Results:

Mechanical forces (shear stress, tensile loads) induce significant changes in stem cell morphology and differentiation.
Extracellular matrix properties (rigidity, topography) are key regulators of stem cell fate.
Cellular responses involve dynamic remodeling of the cytoskeleton and alterations in cell/nucleus size and shape.

Conclusions:

Mechanical cues are as crucial as chemical and biological factors in stem cell differentiation.
Understanding mechanotransduction pathways is vital for controlling stem cell behavior.
Future research should further elucidate the interplay between physical forces and stem cell fate.
