Computational Biology

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

Genes and growing shapes (modelling)

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

Viewing 3D volume images (analysis)

  • 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 OPT (ref) used with fluorescent probes that monitor biological gene activity.
    • Huge amounts of data potentially make viewing slow, but...
  • To interact with the images we implemented VolViewer (cite) which exploits powerful graphics processors.
  • Works with BioformatsConverter to read 3D images in both open and proprietary file formats. Runs on either your computer or a server.
