Matrix elasticity directs stem cell lineage specification.
TLDR
Naive mesenchymal stem cells are shown here to specify lineage and commit to phenotypes with extreme sensitivity to tissue-level elasticity, consistent with the elasticity-insensitive commitment of differentiated cell types.About:

The extracellular matrix in development and morphogenesis: a dynamic view.
TL;DR: The importance of ECM as a dynamic repository for growth factors is highlighted along with more recent studies implicating the 3-dimensional organization and physical properties of theECM as it relates to cell signaling and the regulation of morphogenetic cell behaviors.

Mechanotransduction gone awry.
Diana E. Jaalouk,Jan Lammerding +1 more
TL;DR: Cells sense their physical surroundings through mechanotransduction — that is, by translating mechanical forces and deformations into biochemical signals such as changes in intracellular calcium concentration or by activating diverse signalling pathways, and these signals can adjust cellular and extracellular structure.

Injectable and biodegradable hydrogels: gelation, biodegradation and biomedical applications
TL;DR: The review includes the novel naturally based hydrogels with high potential for biomedical applications developed in the past five years which integrate the excellent biocompatibility of natural polymers/synthetic polypeptides with structural controllability via chemical modification.
Journal ArticleDOI
Stem cell fate dictated solely by altered nanotube dimension
TL;DR: Altering the dimensions of nanotubular-shaped titanium oxide surface structures independently allowed either augmented human mesenchymal stem cell (hMSC) adhesion or a specific differentiation of hMSCs into osteoblasts by using only the geometric cues, absent of osteogenic inducing media.
Journal ArticleDOI
Forming functional fat: a growing understanding of adipocyte differentiation
TL;DR: Improving the understanding of these mechanisms may allow us to identify therapeutic targets against metabolic diseases that are rapidly becoming epidemic globally.

Tissue Cells Feel and Respond to the Stiffness of Their Substrate
TL;DR: An understanding of how tissue cells—including fibroblasts, myocytes, neurons, and other cell types—sense matrix stiffness is just emerging with quantitative studies of cells adhering to gels with which elasticity can be tuned to approximate that of tissues.

Cell shape, cytoskeletal tension, and rhoa regulate stem cell lineage commitment
TL;DR: It is demonstrated that cell shape regulates commitment of human mesenchymal stem cells to adipocyte or osteoblast fate and mechanical cues experienced in developmental and adult contexts, embodied by cell shape, cytoskeletal tension, and RhoA signaling, are integral to the commitment of stem cell fate.

Myofibroblasts and mechano-regulation of connective tissue remodelling
TL;DR: It is clear that the understanding of the myofibroblast — its origins, functions and molecular regulation — will have a profound influence on the future effectiveness not only of tissue engineering but also of regenerative medicine generally.
