Seeking investigators for Collaborative or Service projects through the National Center for Multiscale Modeling of Biological Systems
October 5, 2014
The image analysis and modeling team at the NIH-supported National Center for Multiscale Modeling of Biological Systems would like to bring to your attention an opportunity to engage in a collaborative or service project with researchers at the Center. We are seeking investigators who wish to use CellOrganizer for learning and using generative models of cell size, shape and subcellular organization (or to help with further development). We can provide extensive training to external personnel, consultation on appropriate methods and design of studies, help with local installation of any desired software, and access to computational resources at the Center for image analysis, modeling and simulation. CellOrganizer learns modular models of things such as cell shape, nuclear shape, vesicular organelle distribution and microtubule distribution directly from 2D or 3D images and can produce specific instances of cell geometries without the need to create them by hand or to segment microscope images (see Buck et al, 2012 for an overview). Through Center funding, pipelines have been created whereby these geometries can be combined with biochemical models to perform spatially realistic cell simulations with a minimum of effort (Center resources can be provided to run these using the cell simulation engine MCell. The biochemical models can be encoded in SBML (i.e., investigator created or downloaded from models databases) or can be generated by BioNetGen (a powerful rule-based modeling package). This combination of CellOrganizer and MCell allows investigators to explore the effect of different cell geometries on their models (e.g., to independently explore different modes of variation in the generative models, such as variation in organelle number vs. shape). Existing generative models of 3T3 cells, HeLa cells, and C2C12 cells can be used so that making extensive image collections can be avoided.
If interested, please contact firstname.lastname@example.org or fill out the form at the MMBioS web site. We would be happy to further explain the capabilities of the current system and discuss development of new capabilities.
