The Virtual Cell is a modular computational framework that permits construction of models, application of numerical solvers to perform simulations, and analysis of simulation results. A key feature of the Virtual Cell is that it permits the incorporation of realistic experimental geometries within full 3D spatial models. An intuitive JAVA interface allows access via a web browser and includes options for database access, geometry definition (including directly from microscope images), specification of compartment topology, species definition and assignment, chemical reaction input and computational mesh. The system is designed for cell biologists to aid both the interpretation and the planning of experiments. It also contains sophisticated modelling tools that are appropriate for the needs of mathematical biologists. Thus, communication between these traditionally separate scientific communities can be facilitated. This paper will describe the status of the project and will survey several applications to cell biological problems.
虚拟细胞是一个模块化的计算框架,它允许构建模型、应用数值求解器进行模拟以及分析模拟结果。虚拟细胞的一个关键特性是它允许在完整的三维空间模型中纳入实际的实验几何形状。直观的JAVA界面允许通过网络浏览器访问,包括数据库访问、几何形状定义(包括直接从显微镜图像)、隔室拓扑结构规范、物种定义和分配、化学反应输入以及计算网格等选项。该系统专为细胞生物学家设计,以协助实验的解释和规划。它还包含适合数学生物学家需求的复杂建模工具。因此,可以促进这些传统上相互独立的科学界之间的交流。本文将描述该项目的现状,并概述几个针对细胞生物学问题的应用。
