Some applications
Cell biology                           Software:

Rates of cell division                 Opensource:
Spatio-temporal protein localisation   ImageJ, CellProfiler
Responses of cells to new drugs        R, Python, ITK, VTK
Lineage tracing
Cell motility                          Proprietary:
                                       Matlab, MetaMorph, Volocity, ...
