Cell migration is a central process in the development and maintenance of multicellular organisms.Tissue formation during embryonic development, wound healing and immune responses all require the orchestrated movement of cells in particular directions to specific locations.
Intracellular transport is the movement of vesicles and substances within a cell. Intracellular transport is required for maintaining homeostasis within the cell by responding to physiological signals. [1] Proteins synthesized in the cytosol are distributed to their respective organelles, according to their specific amino acid’s sorting ...
Direct contact between cells allows the receptors on one cell to bind the small molecules attached to the plasma membrane of different cell. In eukaryotes, many of the cells during early development communicate through direct contact. [5] Synaptic signaling, an integral part of nervous system activity, occurs between neurons and target cells.
Collective cell migration describes the movements of group of cells and the emergence of collective behavior from cell-environment interactions and cell-cell communication. Collective cell migration is an essential process in the lives of multicellular organisms , e.g. embryonic development , wound healing and cancer spreading ( metastasis ). [ 1 ]
Cell division. All cells can be considered motile for having the ability to divide into two new daughter cells. [1] Motility is the ability of an organism to move independently using metabolic energy. This biological concept encompasses movement at various levels, from whole organisms to cells and subcellular components.
The interstitial compartment (also called "tissue space") surrounds tissue cells. It is filled with interstitial fluid , including lymph. [ 5 ] Interstitial fluid provides the immediate microenvironment that allows for movement of ions , proteins and nutrients across the cell barrier.
Within frogs and fish, however, there exist fundamental differences in how convergent extension is achieved. Frog embryogenesis utilizes cell rearrangement as the sole player of this process. Fish, on the other hand, utilize both cell rearrangement as well as directed migration [1] (Fig. 1) . Cellular rearrangement is the process by which ...
Cells generate and maintain mechanical forces within their environment as a part of their physiology. Cell biomechanics deals with how mRNA, protein production, and gene expression is affected by said environment and with mechanical properties of isolated molecules or interaction of proteins that make up molecular motors.
