The migration of cultured cells attached to a surface or in 3D is commonly studied using microscopy. [7] [8] [5] As cell movement is very slow, a few μm/minute, time-lapse microscopy videos are recorded of the migrating cells to speed up the movement.
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 ]
Primordial germ cells are among the first lineages that are established in development [1] and they are the precursors for gametes. [2] It is thought that the process of primordial germ cell migration itself has been conserved rather than the specific mechanisms within it, as chemoattraction and repulsion seem to have been borrowed from blood cells, neurones, and the mesoderm. [1]
A study was performed to better understand the role that claudin-7, a family of tight junction proteins, plays in cell migration in a type of human lung cancer cells. [10] Due to the slower migration rate of claudin-7 knockdown cells, it supports the idea that this protein is important in cell migration an cell's ability to metastasize. [10]
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
There exist two main patterns of cancer cell invasion by cell migration: collective cell migration and individual cell migration, by which tumor cells overcome barriers of the extracellular matrix and spread into surrounding tissues. Each pattern of cell migration exhibits distinct morphological features and is governed by specific biochemical ...
The induced migration of cells from the ganglionic eminence during development is directed by a variety of motogenic factors, molecules that increase cell motility, and chemotactic molecules. The motogenic factor HGF/SF enhances cell motility and directs cells away from subpallial regions and demarcates the routes followed by migrating cells.
Migration of cells is free toward and away on the axis of the concentration gradient; Detected responses are the results of active migration of cells; Despite the fact that an ideal chemotaxis assay is still not available, there are several protocols and pieces of equipment that offer good correspondence with the conditions described above. The ...
