Do human mammary epithelial cells exhibit a bimodal correlated random walk pattern?
Because of the presence of non-uniform turn angle distribution of move step-lengths within a flight and two different types of flights, we propose that the epithelial random walk is a BCRW comprising of two alternating modes with varying degree of correlations, rather than a simple persistent random walk. A BCRW model rather than a simple persistent random walk correctly matches the super-diffusivity in the cell migration paths as indicated by simulations based on the BCRW model.
Lack of MHC class II transcription, rather than defects in MHC class II protein function or defects in the other components of the MHC class II-stimulated apoptotic pathway, prevents MHC class II-mediated apoptosis in melanoma cells.
