This paper describes modification of the microtubule model described below in order to allow for estimation of free tubulin, and applies the model to images of cells treated with and without nocodazole to depolymerize microtubules.  The results are consistent with expectation.

This review provides a perspective on methods for estimating pattern fractions and learning generative models.  It addresses the critical problem of representing information learned about subcellular organization for comparison between cell and tissue types and for use in systems simulations.

Methods have been described previously for learning models of cell organization from microscope images in order to be able to synthesize and combine subcellular distributions.  These methods involve direct estimation of the model parameters but for some subcellular patterns (such as those of microtubules or microfilaments), direct estimation is difficult due to large numbers of tangled fibers.  We describe the first method for indirectly learning a microtubule model and show that it produces results consistent with current knowledge.
