Thanks to Wimasis we are now able to extract more information from every image we take

At the chair of Molecular Nutritional Medicine we study the balance between energy intake and expenditure. Thermogenic brown adipocytes profoundly contribute to the latter by dissipating nutrient energy in the form of heat. Characteristic features of brown as compared to white adipocytes are the lower size and greater number of lipid droplets as well as the smaller overall cell size.
Wimasis has developed a custom solutiom to us to automatically determine adipocyte size and number in images of histological sections that saves us hours and hours of manual counting and measuring. Even better, in cooperation with Wimasis, we established an image analysis procedure enabling us to quantify lipid droplet size and number in images of cultured adipocytes. A task that is impossible to perform manually and far less efficient with off-the-shelf particle recognition software in our hands.
With Wimasis image analyses we do not only save a lot of time, but are even able to extract more quantitative information out of every image we take.
Our lab uses cellular and animal models to understand the physiological roles of autophagy and its implications during disease.
Autophagy is an essential intracelullar degradation pathway that recycles cell components generating new building blocks and energy to maintain cellular homeostasis. Autophagy plays an important role in the response to nutrient starvation; the recycling of damaged organelles and is a survival mechanism under stress conditions. In addition, autophagy could as well participate in programmed cell death.
We are interested in the implication of autophagy during development and in the relationship of autophagy with basic processes such as proliferation, differentiation and cell death. Moreover we want to understand how autophagy deregulation may play a role in several pathological situations such as cancer and neurodegenerative conditions.
We have several projects with pharmaceutical companies to screen for new drugs that modulate autophagy with the aim to find new treatments for cancer, neurodegenerative diseases and other pathological conditions.
Wimasis has allowed us to speed up and standardize the process of autophagosome quantification in cells and tissues.
Center for Drug Research, Chair of Pharmaceutical Biology (Prof. Angelika Vollmar)
The Center for Drug Research covers all research areas around the development of novel drug – from chemical synthesis to innovative formulations. At the Chair of Pharmaceutical Biology (Prof. Dr. Angelika Vollmar) we investigate the pharmaceutical potential of natural compounds, be it of plant, animal or microbial origin.
Our main focus lies on tumor biology, with tumor angiogenesis (Prof. Dr. Stefan Zahler) as a central topic. Inhibiting the vessel growth in tumors in order to “starve” the malignancy is an old therapeutic concept, which has led to some clinical success, but still has its limits: due to evasive strategies of the tumors and to development of resistances we are still in need of novel therapeutic targets and inhibitors of angiogenesis. Therefore, not only try to get a better academic understanding of the angiogenesis process, but also screen novel inhibitors. More complex angiogenesis assays, like the tube formation assay, are image based and tedious to evaluate by hand.
Therefore they often are of limited use for screening purposes. The WimTube module overcomes this problem: it enables a robust rational evaluation of tube formation assays, and allows us to use this assay in a medium throughput screening approach.
In addition to the highly reproducible analysis, we also get valuable morphological information, which has to date not been used in classical evaluation routines.
