We developed a virtual physiological mouse heart model, adapting human modeling tools for comparative cardiac research. This computational approach enhances understanding of cardiac function across species, including humans.

Area of Science:

  • Computational biology
  • Physiological modeling
  • Comparative physiology

Background:

  • The Virtual Physiological Human (VPH) project has advanced human computational modeling.
  • Mouse models are crucial in research but lack comprehensive computational counterparts.
  • Bridging this gap offers insights into cardiac function and human physiology.

Purpose of the Study:

  • To create a virtual physiological mouse heart model.
  • To adapt VPH tools and methods for interspecies cardiac modeling.
  • To investigate cardiac muscle properties and multi-scale hypotheses.

Main Methods:

  • Reusing Virtual Physiological Human (VPH) tools for mouse heart modeling.
  • Developing species-agnostic parameter sensitivity analysis methods.
