VCell 7.0 has been released to the public beta site. 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 […]
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.
2017-11-25. A new VCell model explores the effect of SH2 domain overexpression on the EGFR signaling pathway in a publication by Jadwin et al. The results suggest that signaling via SH2 domain binding is buffered over a wide range of concentrations. Explore the model from the listing on our Published Models page
2017-8-27. In a new publication from Acevedo et al (2017) binding interactions between VASP and the cytoskeletal adapter protein Zyxin were explored using a VCell model to predict the population distribution of different molecular complexes based on different kinetic parameters. Find a link to the publication in our published models list.
2017-07-30. A new PNAS publication by Jung et al. is the latest in a series of VCell models published by the Hille lab. This new model explores the role of arrestin in regulating ERK activity during GPCR signaling. View the model structure through our list of published models.
2017-07-10. A new publication in Biophysical Journal by Mohan et al. uses a VCell model to define mechanisms for signal amplification in the PLC/PKC pathway during chemotaxis. Link to the publication and view model details from our Published Models listing.
