Matrix Control of Stem Cell Fate
A key challenge in stem cell research is to learn how to direct the differentiation of stem cells toward specific fates. In this issue of Cell, Engler et al. (2006) identify a new factor regulating stem cell fate: the elasticity of the matrix microenvironment. By changing the stiffness of the substrate, human mesenchymal stem cells could be directed along neuronal, muscle, or bone lineages.
متن کاملEpigenetic control of embryonic stem cell fate
Embryonic stem (ES) cells are derived from the inner cell mass of the preimplantation embryo and are pluripotent, as they are able to differentiate into all cell types of the adult organism. Once established, the pluripotent ES cells can be maintained under defined culture conditions, but can also be induced rapidly to differentiate. Maintaining this balance of stability versus plasticity is a ...
متن کاملEpigenetic control of neural stem cell fate.
Unraveling the mechanisms by which neural stem cells generate distinct cell types remains a central challenge in central nervous system (CNS) biology. Recent studies have shown that epigenetic gene regulation plays an important role in the control of cell growth and differentiation. These epigenetic controls cover a wide spectrum, including the interaction of chromatin remodeling enzymes with n...
متن کاملGeometry–Force Control of Stem Cell Fate
Tissue engineering requires tight control of stem cell function. Among many physical signals such as stretch and perfusion, geometrical cues have received much attention and have widely been recognized as an important factor in scaffold design. Here we review a variety of approaches that control stem cell fate at different levels of strictness, including micro-contact printing, microwells, dire...
متن کاملHarnessing Traction-Mediated Manipulation of the Cell-Matrix Interface to Control Stem Cell Fate
Stem cells sense and respond to the mechanical properties of the extracellular matrix. However, both the extent to which extracellular-matrix mechanics affect stem-cell fate in three-dimensional microenvironments and the underlying biophysical mechanisms are unclear. We demonstrate that the commitment of mesenchymal stem-cell populations changes in response to the rigidity of three-dimensional ...
