The molecular engineering of cell-instructive artificial extracellular matrices is a powerful means to control cell behavior and enable complex processes of tissue formation and regeneration. This work reports on a novel method to produce such smart biomat ...
Photodynamic therapy (PDT) can be used to cause vascular collapse and blood flow stasis of the irradiated pathological neovascularisation appearing in several diseases such as age-related macular degeneration (AMD) and cancer. We hypothesized that this PDT ...
Fibroblast-to-myofibroblast differentiation - a key event in the development of fibrocontractive diseases and in wound granulation tissue contraction - is hallmarked by the formation of stress fibers and the neo-expression of alpha-smooth muscle actin. Inc ...
Local, controlled induction of angiogenesis remains a challenge that limits tissue engineering approaches to replace or restore diseased tissues. We present a new class of bioactive synthetic hydrogel matrices based on poly(ethylene glycol) (PEG) and synth ...
An increasing number of patients are being treated with growth hormone (GH) for the enhancement of body growth but also as an anti-aging strategy. However, the side effects of GH have been poorly defined. In this study we determined the effect of GH on wou ...

Cell organization is largely orchestrated by extracellular gradients of morphogenetic proteins. VEGF, an essential factor for capillary formation, is stored in the extracellular matrix, but the mechanisms by which it and other matrix-bound morphogens are m ...
The lack of angiogenesis in ischemic tissues is a major health problem and many studies aim to explore strategies to locally increase blood perfusion. Our approach is to use covalently modified fibrin-based hydrogels as a matrix that induces endothelial ce ...
Notch receptors are important mediators of cell fate during embryogenesis, but their role in adult physiology, particularly in postnatal angiogenesis, remains unknown. Of the Notch receptors, only Notch1 and Notch4 are expressed in vascular endothelial cel ...
We sought to develop bioactive hydrogels to facilitate arterial healing, e.g., after balloon angioplasty. Toward this end, we developed a new class of proteolytically sensitive, biol. active polyethylene glycol (PEG)-peptide hydrogels that can be formed in ...
Previous studies demonstrated that IGF-II binds directly to vitronectin (VN), whereas IGF-I binds poorly. However, binding of VN to integrins has been demonstrated to be essential for a range of IGF-I-stimulated biological effects, including IGF binding pr ...
