Collective Mechanism of Cell Motion
Schematic representation of the collective biomechanical and molecular mechanism of cell motion

Amoeboid movement is the most common type of movement in eukaryotic cells.

It is a crawling type of movement got by pushing out cell cytoplasm in the form of pseudopodia ("false feet"). The cytoplasm slides and forms a pseudopodium in front to move the cell forward.

This type of movement is observed in amoebae, slime molds and some other protozoans such as Naegleria gruberi, as well as some cells in humans such as white blood cells. Sarcomas, or cancers arising from connective tissue cells, are particularly good at amoeboid movement, thus leading to their high rate of metastasis.

The exact mechanism is still unknown. It involves actin-myosin molecules inside the cytoplasm.
