17-11-2018. Announcing the release of VCell 7.1. VCell 7.1 adds the ability to explore existing models in the database and VCell functionality without registration. It has an improved model database info panel with model provenance, annotations, direct links to Pubmed and journal websites for models described in publications. These add to the new features for 2D kinematics to solve simulations with moving boundaries and the ability to use the COMSOL Multiphysics solver already in VCell 7.0.
2018-07-10. A new Vcell spatial model of calcium influx, buffering and diffusion in mossy fiber boutons was published by Chamberland and co-authors in PNAS. Visit our published models page for links to the paper.
2018-6-18 VCell hosted its 19th annual VCell Short Course on June 12-14, 2018. Ten scientists traveled to work with the VCell team to construct Virtual Cell models based on their own research interests. It was exciting to see the breadth of cell biological problems to which VCell models were applied. Thanks to all for a successful time!
2018-3-15 Announcing the release of VCell 7.0. VCell 7 includes new 2D kinematics functionality for solving reaction diffusion equations within moving boundaries. To support models of cell motility and morphogenesis, this allows users to specify velocities of points, surfaces and volumes within the geometry. Other features in VCell 7.0 are methods for creating simulated fluorescence for direct comparison to microscopy data, the ability to use COMSOL Multiphysics solver (requires a local COMSOL license) and adaptive meshes for simulating […]
2018-03-13. A paper by Kinglsey et al assesses the effects of complex geometries on FRAP recovery curves. They develop a computational model of the FRAP processes to assess methods of analyzing FRAP experiments. They determined that the Vcell VirtualFRAP tool provides the best accuracy to measure diffusion coefficients. A link to the paper can be found on our published models page.
2018-02-21. Leslie Loew received the Distinguished Service Award of the Biophysical Society at its 2017 annual meeting February 17-21. The award acknowledged his ongoing commitment to the Society and his dedicated service as Editor-in-Chief of Biophysical Journal. Congratulations to Les for this well-deserved award.
2017-12-15. A new publication from the Iyngar, Hone and He laboratories using Vcell among a number of other modeling strategies to explore how cell shape information can alter cellular phenotype via tension-independent mechansims. A link to the publication is found in our published models list.
11-30-2017. Version 2 of the SpringSaLaD software was released today. The primary new feature is the ability to directly build models from atomic coordinates in pdb files, using an interactive 3D viewer to compare the course-grained linked spheres representation in SpringSaLaD with the PDB structure.
11-14-2017. A new publication, Nickaeen et al. 2017, from the VCell team describes a novel free-boundary model of actin -myosin contractility that couples force-balance and myosin transport equations. A previously developed mass-conservation algorithm originally developed for VCell to solve parabolic equations in moving domains with know kinematics was augmented by coupling with the FronTier front-tracking software and a segregated solver.
2017-12-06. Simulations from a VCell model were used to estimate the diffusion coefficient of myosin II in fission yeast in a new publication from the Pollard laboratory. Visit our published models page for links to the paper and the public model.
