Engineering Robotic Sensing and Stimuli Provision for Guided Plant Growth Mostafa Wahby1, Mary Katherine Heinrich1,5, Daniel Nicolas Hofstadler2, Julian Petzold1, Igor Kuksin3, Payam Zahadat2,4, Thomas Schmickl2, Phil Ayres5, Heiko Hamann1 1Institute of Computer Engineering, University of Lübeck, 2Institute of Biology, Artificial Life Lab, University of Graz, 3Cybertronica UG, 4Department of Computer Science, IT University of Copenhagen, 5Centre for IT and Architecture, Royal Danish Academy Distributed robot nodes provide sequences of blue light stimuli to steer the growth trajectories of climbing plants. By activating natural phototropism, the robots guide the plants through binary left-right decisions, growing them into predefined patterns that by contrast are not possible when the robots are dormant. Immunology and Infection Isolation and Flow Cytometric Analysis of Immune Cells from the Ischemic Mouse Brain Claudia Pösel*1, Karoline Möller*1, Johannes Boltze1,2, Daniel-Christoph Wagner1, Gesa Weise1,3 1Ischemia Research Unit, Fraunhofer Institute for Cell Therapy and Immunology, 2Fraunhofer Research Institution for Marine Biotechnology, University of Lubeck, 3Department of Neurology, University of Leipzig Inflammation plays a central role in the pathogenesis of ischemic stroke. Increasing evidence suggests that it acts as a double-edged sword which exacerbates early brain injury, but also contributes to later repair. This protocol describes the isolation of immune cells from the ischemic brain and their subsequent flow cytometric phenotyping. Bioengineering A Full Skin Defect Model to Evaluate Vascularization of Biomaterials In Vivo Thilo L. Schenck1, Myra N. Chávez1, Alexandru P.

Therefore, reliable technologies are required to evaluate the development of vascular networks in tissue-constructs. Here we present a simple and cost-effective method to visualize and quantify vascularization in vivo.
