The collective cell migration is observed in many biological processes such as wound healing, embryogenesis, and cancer metastasis. Despite extensive theoretical and experimental studies on collective cell motion, there is no unified mechanism to explain it. In this work, we experimentally report the collectively growing cell colonies in the sub-marginal region of a freely expanding cell monolayer. These colonies could be responsible for the highly aligned collective cell migration observed in front cell rows. Our results provide a basic framework to understand the physical mechanism responsible for collective cell migration in the freely expanding monolayer.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
