Abstract: Summary Cell movement in 3-dimensional tissues is important in various biological processes such as cell-sorting, wound healing, and metastasis. Unlike solitary cells attached to a fiat surface, motile cells tightly packed in 3-dimensional tissues are under strong mechanical constraints, but nevertheless they can still move actively by getting traction from the neighbouring cells. Here, I will describe some characteristics of cell movements in isolation and within multicellular tissues in the cellular slime mould Dictyostelium, and propose a possible mechanism whereby the cells inside a tissue can get traction from the substratum. Based on this hypothesis, models for cell sorting and for the generation of coherent motion of cells in tissues will also be outlined.
