We present an automated method for the tracking and dynamics
modeling of microtubules -a major component of the
cytoskeleton- which provides researchers with a previously
unattainable level of data analysis and quantification capabilities.
The proposed method improves upon the manual
tracking and analysis techniques by i) increasing accuracy
and quantified sample size in data collection, ii) eliminating
user bias and standardizing analysis, iii) making available
new features that are impractical to capture manually,
iv) enabling statistical extraction of dynamics patterns from
cellular processes, and v) greatly reducing required time
for entire studies. An automated procedure is proposed to
track each resolvable microtubule, whose aggregate activity
is then modeled by mixtures of Hidden Markov Models
to uncover dynamics patterns of underlying cellular and
experimental conditions. Our results support manually established
findings on an actual microtubule dataset and illustrate
how automated analysis of spatial and temporal
patterns offers previously unattainable insights to cellular
processes.
