Release of Growth Cone Analyzer: A new method to quantify morphological variation among complex cellular architectures.
Growth cones are complex, motile structures at the tip of an outgrowing neurite. They often exhibit a high density of filopodia (thin actin bundles), which complicates the unbiased quantification of their morphologies by software. Contemporary image processing methods require extensive tuning of segmentation parameters and are often not sufficiently adaptable to capture morphology changes associated with switches in regulatory signals.
In a study recently published in the Journal of Cell Biology, Bagonis et al. devise a method to overcome such limitations. The robustness of this new tool enabled the study of morphological variation and its relation to motility in both an unperturbed system and in the context of modified Rho GTPase signaling.
The project was initiated jointly with the lab of Dr. Olivier Pertz at the University of Bern.
