Stem cell-based cardiovascular tissue engineering

Cardiovascular diseases, including myocardial infarction, are the leading cause of death worldwide for both men and women. Current therapies are limited by the restricted intrinsic regeneration capacity of the heart and by the lack of organs for transplant ...

Coassembly of Mgm1 isoforms requires cardiolipin and mediates mitochondrial inner membrane fusion

Henning Paul-Julius Stahlberg

Two dynamin-related protein (DRP) families are essential for fusion of the outer and inner mitochondrial membranes, Fzo1 (yeast)/Mfn1/Mfn2 (mammals) and Mgm1 (yeast)/Opa1 (mammals), respectively. Fzo1/Mfns possess two medial transmembrane domains, which pl ...

Three-dimensional extracellular matrix-directed cardioprogenitor differentiation: Systematic modulation of a synthetic cell-responsive PEG-hydrogel

Matthias Lütolf, Jeffrey Alan Hubbell

We show that synthetic three-dimensional (3D) matrix metalloproteinase (MMP)-sensitive poly(ethylene glycol) (PEG)-based hydrogels can direct differentiation of pluripotent cardioprogenitors, using P19 embryonal carcinoma (EC) cells as a model, along a car ...

Myofibroblast communication is controlled by intercellular mechanical coupling

Jean-Jacques Meister, Boris Hinz, Sébastien Schaub, Lysianne Follonier Castella

Neoformation of intercellular adherens junctions accompanies the differentiation of fibroblasts into contractile myofibroblasts, a key event during development of fibrosis and in wound healing. We have previously shown that intercellular mechanical couplin ...

Comparative maps of motion and assembly of filamentous actin and myosin II in migrating cells

Jean-Jacques Meister, Sébastien Schaub, Sophie Bohnet

To understand the mechanism of cell migration, one needs to know how the parts of the motile machinery of the cell are assembled and how they move with respect to each other. Actin and myosin II are thought to be the major structural and force-generating c ...

The May-Hegglin anomaly gene MYH9 is a negative regulator of platelet biogenesis modulated by the Rho-ROCK pathway

Olaia Maria Naveiras Torres-Quiroga, Zhao Chen

The gene implicated in the May-Hegglin anomaly and related macrothrombocytopenias, MYH9, encodes myosin-IIA, a protein that enables morphogenesis in diverse cell types. Defective myosin-IIA complexes are presumed to perturb megakaryocyte (MK) differentiati ...

Dynamics of actin and myosin II during cell polarization and directional locomotion

Sophie Bohnet

Crawling cell motility is characteristic of most animal cells and is involved in many important biological processes such as embryogenesis, immune response, and wound healing. It involves several steps: protrusion (dynamic surface extension) at the front o ...

Structure and dynamics of actin network at the leading edge of migrating cells

Sébastien Schaub

Crawling motion is characteristic of most animal cells and is principally based on actin-myosin II cytoskeletal system. The major components and reactions contributing to motility have been identified, but the overall picture of how these molecular events ...

Contraction of myofibroblasts in granulation tissue is dependent on Rho/Rho kinase/myosin light chain phosphatase activity

Boris Hinz, Michael David Martin

During wound healing and fibrocontractive diseases fibroblasts acquire a smooth muscle cell-like phenotype by differentiating into contractile force generating myofibroblasts. We examined whether regulation of myofibroblast contraction in granulation tissu ...

PGC-1alpha: turbocharging mitochondria

Johan Auwerx

PGC-1alpha plays essential and diverse functions in the control of metabolism ranging from mitochondrial biogenesis and respiration to hepatic gluconeogenesis and muscle fiber-type switching. In a paper in this issue of Cell, the characterization of PGC-1a ...
