Cell movement is a complex process and plays a critical role in diverse physiological and pathological processes, such as embryonic development, wound healing, immune responses, outgrowth and metastasis of cancer cells, and angiogenesis.When an endogenous eye field is replaced with a control (uninjected) animal cap, the donor cells form only epidermis—the surface skin of the host tadpole (Cultured normal cells move and proliferate until they become confluent and form cell–cell junctions.

Cilia, hairlike structures that extend from the surface of many cells, can create movement of surrounding fluid. The resistance to compression force is provided by the actin cytoskeleton; therefore, surface tension strongly depends on actin filament organization. The idea that surface tension can facilitate cell sorting is not a new concept, since cells with lower surface tension were shown to envelop cells with higher surface tension.Interestingly, the relationship between surface tension and cadherin levels may not apply to all cell types. These molecules give cells the ability to grow and For example, during morphogenesis there is a targeted movement of dividing cells to specific sites to form tissues and organs. This phenomenon was identified over a half century ago as contact inhibition of cell movement and proliferation (Cell adhesion includes cell–cell and cell–matrix junctions. In contrast, bacterial cells do not contain organelles.Cells ingest molecules through their plasma membranes. The centrosome contains the centrioles, which play a role in cell division. Cells often migrate in response to specific external signals, including chemical signals and mechanical signals. The cells responded by increasing the resistive forces and/or reinforcing the integrin-cytoskeleton linkages (Wang et al., 1993, Choquet et al., 1997). Peroxisomes contain enzymes that detoxify dangerous substances.
Distinguish from CYTOKINESIS which is the process of dividing the CYTOPLASM of a cell. Another crucial actin function, the generation of force necessary for cell crawling, has not been addressed in cell sorting assays. Definition of cell movement in the Definitions.net dictionary.

Certain proteins in the cell membrane are involved with cell-to-cell communication and help the cell to respond to changes in its environment.
