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 ...
Fibrin aggregation is of vital importance in many physiological and pathological processes, such as blood coagulation, wound healing, and thrombosis. In the present study, we investigated the forces involved in the initial steps of the fibrinogen fibrin ag ...
This report will focus on creation of nanostructured PDMS surfaces with tunable feature dimensions and periodicities, and the use of these surfaces to study the influence of nanotopography on cell-substrate interactions. The topography on surfaces is known ...
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 ...
The crucial role played by the myofibroblast in wound healing and pathological organ remodeling is well established; the general mechanisms of extracellular matrix synthesis and of tension production by this cell have been amply clarified. This review disc ...
Septic injury triggers a rapid and widespread response in Drosophila adults that involves the up-regulation of many genes required to combat infection and for wound healing. Genome-wide expression profiling has already demonstrated that this response is co ...
We describe the design and performance of a new full-field high-speed laser Doppler imaging system developed for mapping and monitoring of blood flow in biological tissue. The total imaging time for 256x256 pixels region of interest is 1.2 seconds. An inte ...
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 ...
During wound healing and in a variety of fibrocontractive diseases, fibroblasts differentiate into contractile myofibroblasts by acquiring stress fibers and by expressing α-smooth muscle actin (α-SMA). Myofibroblasts of wound granulation tissue, in contras ...
We studied the mechanisms underlying the severely impaired wound healing associated with human leukocyte-adhesion deficiency syndrome-1 (LAD1) using a murine disease model. In CD18(-/-) mice, healing of full-thickness wounds was severely delayed during gra ...
