Matrix Elasticity Directs Stem Cell Lineage Specification

Microenvironments appear important in stem cell lineage specification but can be difficult to adequately characterize or control with soft tissues. Naive mesenchymal stem cells (MSCs) are shown here to specify lineage and commit to phenotypes with extreme sensitivity to tissue-level elasticity. Soft matrices that mimic brain are neurogenic, stiffer matrices that mimic muscle are myogenic, and c...

Extracellular matrix elasticity directs stem cell differentiation.

Stem cell differentiation is regulated by a variety of cues including growth factors and extracellular matrix (ECM), although the role that the ECM has in this process is less understood. Here we provide examples of how the composition, concentration, and elastic modulus of matrix as well as its temporal and spatial location plays a key role in regulating cell fate. Natural variation of matrix ...

Microgravity directs stem cell differentiation.

Stem cells are the cell of origin for organisms and their organs. These cells are critical for tissue regeneration, as well as regenerative medicine. Mechanical forces, such as gravity, have been demonstrated to provide important signals for stem cell fate. In fact, the absence of gravity, that is, microgravity, affects almost all aspects of human physiology, which has been partly attributed to...

Cell lineage specification at single cell resolution.

Single cell technology has been widely used in developmental and stem cell biology. In mouse, single cell transcriptome has revealed the cell lineage specification in pre-implantation and post-implantation stage embryo. Now Mohammed et al. investigated the dynamic cell fate commitment during the transition from peri-implantation to early post-implantation stage with single cell RNA sequencing. ...

Stem cell leukemia protein directs hematopoietic stem cell fate.

Stem cell leukemia (SCL) protein has been shown to be an essential transcription factor during hematopoietic development in the embryo. In adult hematopoiesis, however, the role for SCL has remained largely unknown, whereas it is expressed in bone marrow hematopoietic stem cells (HSCs). In this study, we performed HSC transplantation and an in vitro HSC differentiation assay using retrovirally ...
