 +**Quantitative measurement and modeling of cell size dependent spindle elongation in the C.Elegans Embryo**
 +
 +Cell Architecture Laboratory, Center for Frontier Research, National Institute of Genetics, Mishima, Japan
 +
 +**Abstract:​** The cell is a highly organized architecture that the positions, sizes, and shapes of intracellular organelles and other components are important for cell functions. Cell size is a critical parameter to control the size of intracellular structures. However, how cell size regulates the size of the intracellular structures is poorly understood. The mitotic spindle, a molecular machine that assembles and segregates chromosomes during cell division, is an important example whose size depends on cell size. We investigated the mechanism underlying the cell size-dependency of spindle elongation using Caenorhabditis elegans embryo as a model system. Quantitative measurements of spindle elongation in cells with various sizes revealed that the length and speed of spindle elongation depended on the cell size. Gene knockdown studies indicated that there are (at least) two qualitatively distinct mechanisms contributing to the cell size-dependent elongation of the spindle. Based on these observations and previous studies, we built several hypotheses that might account for the cell size-dependent elongation. We computed the consequences of these candidate hypotheses using computer simulation, and compared them with the behavior in vivo. A combination of two hypotheses reproduced the in vivo behavior, which led us to propose the first mechanical model for cell size-dependent spindle elongation [1]. The proposed model on spindle elongation was combined with previously proposed models on the migrations of the nucleus [2] and spindle [3], and will be integrated with future studies on other structures, to construct and improve a 4-dimensional cell model for better understanding of the mechanics inside the cell.

 +**Visual Analysis Tools for Multivariate Image Data**\\
 +
 +**Abstract:​** Traditional immunofluorescence microscopy techniques recently have been extended to colocalize, i.e. to simultaneously label and image, a large number of proteins. The Toponome Imaging system (MELC/TIS) by Walter Schubert makes is possible to colocalize up to 100 and more proteins in a single fixed probe, aiming at gaining new insights into complex protein-protein functional networks (Schubert et al., Nature Biotechnology,​ Vol 24, 2006) . The challenge for analyzing the resulting multivariate image data sets lies in making both, the contained spatial information as well as the high-dimensional protein abundance data, readable to biological and medical experts in an interlinked and yet comprehensive way. For this purpose we demonstrate the efficiency of our visualization software tool Lasagne, which provides an interactive,​ real-time navigation through one or multiple data sets. It allows for a fast overview of the data, an in-depth annotation of histological features as well as a comparison of data sets. Data sets shown include MELC/TIS images of human tissue sections affected by the Psoriasis skin disease, and we also demonstrate the application of the Lasagne tool to other imaging techniques like spatially resolved FT-IR microspectroscopy. \\

 +**3D Image Segmentation for Neural Circuit Reconstruction**\\
 +
 +**Abstract:​** Serial Block Face Scanning Electron Microscopy (SBFSEM) has facilitated the 3D imaging of nervous systems at an isotropic resolution of 25 nm per voxel. Using SBFSEM, all neurites within a sample are imaged simultaneously and samples as large as an entire neocortical column can be processed. In order to automatically reconstruct the wiring diagram of a nervous system from an SBFSEM volume image, accurate 3D image segmentation is required. Established algorithms fail to provide the required accuracy. A new method developed at the Heidelberg Collaboratory for Image Processing goes beyond these algorithms by incorporating the non-local structure found in the volume image into the segmentation procedure. Moreover, segmentation criteria are not hand-crafted into the algorithm but are learned from a small subset of the data which was carefully traced by neuroscientists. Segmentation is finally cast into a global optimization problem which combines non-local image features with descriptors of the local image geometry. This method doubles the performance of a previous approach which did not use global optimization. The accuracy is not yet sufficient to allow for an automated analysis of synaptic connectivity. However, the 3D reconstructions provide insight into the geometry of nervous systems and serve as a starting point for semi-automatic procedures. ​

 +**Pattern Analysis and Visualization in Computer-Aided Diagnosis:​Cross-Fertilization between Biomedical Imaging and Engineering**\\
 +
 +**Abstract:​** Technical innovations in medical cross-sectional imaging have opened up new vistas for the exploration of the human body, enabling both high spatial and temporal resolution. However, these techniques have led to vast amounts of image data whose precise and reliable visual analysis by medical doctors and bioscientists requires a considerable amount of human intervention and expertise, thus resulting in a cost factor of substantial economic relevance. Hence, the computer-assisted analysis of medical image data has moved into the focus of interest as an issue of high priority research efforts. The talk covers novel methods for pattern analysis, visualization and computer-aided diagnosis in the field of biomedical imaging, specifically MRI, such as functional MRI for human brain mapping, dynamic cerebral contrast-enhanced perfusion MRI and new approaches to breast cancer diagnosis in MRI mammography. An outlook to topical projects in systems biology confirms the broad applicability of the presented methods.\\

 +
 +Microtubules are protein polymers that form an integral part of functional cytoskeletal networks inside eukaryotic cells. Specific microtubule networks are central to the organization of the intracellular space and they are involved in the control of  cell morphology. To understand how microtubules fulfill these functions it is important to understand how the lengths of microtubules are adapted to cell size and shape. In fact, individual microtubules typically have no fixed length but constantly switch between a growing and a shrinking state in a process termed dynamic instability. One of the keys to better understand microtubule function is to investigate how the rates that govern microtubule dynamics are regulated inside cells.\\
 +In interphase fission yeast (S. Pombe) cells, microtubule catastrophes occur preferentially at the distal ends of elongating cells, but the mechanism by which this spatial selectivity is obtained is not yet understood. We developed automated image analysis procedures to measure microtubule catastrophe rates with unprecedented statistics and at high spatial resolution. We find that: (i) pushing forces generated by growing microtubules induce catastrophes specifically at the cell poles; and (ii) long microtubules undergo catastrophes more often than short ones. Moreover, we show that the microtubule destabilizing motor proteins Klp5/Klp6 enhances the catastrophe rate in a spatially selective way.\\

 +
 +**Abstract:​** ​ With the successful result of Human Genome Project, we are facing the problem of handling numerous target genes whose functions remain to be studied. ​ In chemical genetics, instead of using gene knock-out or overexpression as in conventional genetics, a small molecule library is used to disclose a novel phenotype, eventually for the study of gene function. The most serious bottleneck of modern chemical genetics is target identification. ​ To surrogate the currently popular affinity matrix technique, our group has developed fluorescence libraries for a visualization of the biological events. ​ High throughput strategy using colorful chemical genetics will open the efficient road to chemical genomics and proteomics.\\

 +**Morphometry and Algorithms: Categorization of spindle shapes by fuzzy logic**
 +  - Task of the reaserach is to develop methods for a drug screening.
 +    - Find out the population ratio of cells with anomalous spindle shapes. ​
 +  - Introductory explanation for the Fuzzy logic was given.
 +    - Fuzzy logic uses linguistic variables for both input values and output values to conclude a decision which seemingly is fuzzy for drawing a conclusion with classic binary logic. The spindle shape & patterns are various and complex - fuzzy.\\
 +    - For this reason, fuzzy logic was used. Spindle shape and patterns where successfully categorized using the morphometric parameters such as area, convex-hull,​ orientation,​ orientation matching, distance between spindle pair.
