We use simulations of the biological processes of morphogenesis and phylogenesis to create novel, naturalistic virtual 3-D objects and object categories that can then be rendered as visual images or haptic objects. Biology Lipid Vesicle-mediated Affinity Chromatography using Magnetic Activated Cell Sorting (LIMACS): a Novel Method to Analyze Protein-lipid Interaction Erhard Bieberich1 1Institute of Molecular Medicine and Genetics, Georgia Health Sciences University To test the interaction of a protein with its target lipid we used MACS and Annexin V-conjugated magnetic beads and lipid vesicles synthesized from the target lipid and Annexin V-binding phosphatidylserine. Proteins bound to the target lipid are co-purified and analyzed after elution from the beads. Immunology and Infection Experimental Metastasis and CTL Adoptive Transfer Immunotherapy Mouse Model Mary Zimmerman*1, Xiaolin Hu*1, Kebin Liu1 1Department of Biochemistry and Molecular Biology, Medical College of Georgia An experimental lung metastasis and CTL immunotherapy mouse model for analysis of tumor cells-T cell interaction in vivo. Biology Multicolor Time-lapse Imaging of Transgenic Zebrafish: Visualizing Retinal Stem Cells Activated by Targeted Neuronal Cell Ablation Junko Ariga*1, Steven L. Walker*1, Jeff S. Mumm1 1Department of Cellular Biology and Anatomy, Medical College of Georgia In this video, techniques for multicolor confocal time-lapse imaging and targeted cell ablation are provided. Time-lapse imaging is used to monitor the behavior of multiple cell types of interest in vivo. Targeted cell ablation facilitates the study neural circuit function and cell-specific neuronal regeneration paradigms.
