Hypoxia triggers collective aerotactic migration in Dictyostelium discoideum
eLife, 2021 Using a self-generated hypoxic assay, we show that the amoeba Dictyostelium discoideum displays a remarkable collective aerotactic behavior. When a cell colony is covered, cells quickly consume the available oxygen (O2) and form a dense ring moving ...
