The tumour cells can disseminate into the organism by using the blood or lymphatic stream. Recent data suggest that the site of implantation of secondary foci or metastases is preset by the elaboration of an appropriate microenvironment.
These novel information led to the emerging concept of “premetastatic niche”. In addition, cancer cells must acquire new properties ensuring their mobility and the invasion of various tissues. Cancer stem cells are thought to constitute the proliferative potential of the tumoral mass and could represent the source of cells metastasizing.
The tumour cell-centrered view of the metastatic process is now revisited taking into account the important contribution of the tumor microenvironment consisting of both cellular and non cellular components, in primary tumors as well as in secondary foci.
A new European network, entitled MICROENVIMET, developed within the 7th EU framework is coordinated by Professor Agnès NOEL (Laboratory of Tumour and the Development Biology, GIGA-Cancer research center of the University of Liege, Belgium). This European scientific network entitled “Microenvimet: Understanding and fighting metastasis by modulating the tumour microenvironment through interference with the protease network” (http://www.microenvimet.eu) gathers 8 international partners. It is funded to the amount of 2.999.689 euro for 4 years by the European commission.
The purpose of the project “microenvimet” is to elucidate and understand the early mechanisms of the metastatic dissemination by studying the contribution of tumour microenvironment during various stages of epithelial cancer evolution: the primary tumour growth, the premetastatic phase preceding the dissemination of the cancer cells and the metastatic phase during which the secondary foci develop. It aims at identifying molecular targets contributing to early steps of the tumour progression. The project is focused on the mechanisms underlying the elaboration of a favorable «soil » for the establishment of metastases (“premetastatic niche”).
Its original approach consists in modifying the tumoral microenvironment, interfering with proteases which constitute important regulators of the interactions which are established between tumoral cells and their cellular and molecular microenvironment. This project is based on the exploitation of innovating technological platforms: genomic platform for the analysis of the RNA messengers and the recently identified microRNA, phage library for the development of blocking antibodies against the identified targets, platform of computer-assisted image analysis and transgenesis platform.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
