Computational Biology

The aim is to understand how patterns of gene activity in biological organs influence the developing shape.

Genes and growing shapes

  • Observed: patterns of gene activity regulate tissue growth.
  • Hypothesis: gene activity independently regulates direction of growth.
  • Formalised in the Growing Polarised Tissue Framework (cite).
  • Implemented GFtbox (cite) to develop ideas on growth and form.
  • Start with a sheet of tissue (the canvas) with observed, or hypothetical patterns of growth factor activity.
  • Grow the canvas in 3D under constraints of tissue continuity
  • Compare with observed data quantitatively

Working with 3D volume images

  • Three dimensional (3D) volume images are key to understanding the development of shape.
  • Produced by
    • CT X-ray scanners, MRI and PET.
    • Confocal microscopy and optical projection microscopy (cite) used to view fluorescent probes probes that monitor biological gene activity.
  • VolViewer (cite) exploits powerful graphics processors.
  • Works with BioformatsConverter to read open and proprietary file formats
