Tracking collective cell motion by topological data analysis
Fig 11
Simulation of the antagonistic migration assay: One population advances pushing back the other.
Junction tensions are Λ11 = −6.2, Λ22 = −6.8, which yield shape indices 3.50 (green cells) and 3.84 (magenta cells), respectively. Other parameters are listed in the first row of Table 2, and correspond to weak population mixing. Snapshots are taken at times 2 h, 6.5 h, 13 h, 20 h. See S3 Video.
