Whole-Cell Computational Model of Mycoplasma genitalium
- The goal of this project was to develop the first detailed, "whole-cell" computational model of the entire life cycle of living organism, <i>Mycoplasma genitalium</i>. The model describes the dynamics of every molecule over the entire life cycle and accounts for the specific function of every annotated gene product.
We anticipate that whole-cell models will be critical for synthetic biology and personalized medicine. Please see the project website <a href="http://wholecell.org">wholecell.org</a> and the Downloads page to explore the whole-cell knowledge base and simulations and obtain the model code. | |

DeepCell: Deep convolutional neural networks for image segmentation
- The assignment of a cellular identity to individual pixels in microscopy images is a key technical challenge for many live-cell experiments. Traditional approaches to this image segmentation problem have relied on standard computer vision techniques, such as thresholding, morphological operations, and the watershed transform. While these approaches have enabled the analysis of numerous experiments, they are limited in their robustness and in applicability. Here, we show that deep convolutional neural networks, a supervised machine learning method, can robustly segment the cytoplasms of individual bacterial and mammalian cells. This approach automates the analysis of thousands of bacterial cells and leads to more accurate quantification of localization based fluorescent reporters in mammalian cells. In addition, this approach can also simultaneously segment and identify different mammalian cell types in co-cultures. Deep convolutional neural networks have had a transformative impact on the problem of image classification, and we anticipate that they will have a similar impact for live-cell imaging experiments.

NetworkPainter: Biological pathway animation
- NetworkPainter is a web-based program for drawing and painting signaling network diagrams with high-dimensional cytometry data. Two versions of NetworkPainter are available. The <a href="http://covert.stanford.edu/networkpainter">NetworkPainter stand-alone version</a> is capable of visualizing any uploaded cytometry data. NetworkPainter is also available through the <a href="http://www.cytobank.org/networkpainter.html">Cytobank</a> flow cytometry repository. This version is capable of analyzing flow and mass cytometry data stored in Cytobank. | |

In Silico Liver (ISL) - Multi-level, multi-attribute model mechanisms
- The ISL project consists of a body of Java code used and reused for exploring hypothetical liver mechanisms. The codebase is designed to allow for multiple distinct use cases and experimental designs, some of which we've published already. The scale/resolution of focus changes depending on the use case/experiment being considered. Typically, the hypothetical mechanism is finer grained than the falsifcation/validation data available. Much of the published work focuses on intracellular mechanisms, which requires the cellular and tissue contexts to be defined according to the literature. | |
