The scratch assay is a great tool to study cell migration since this mechanism is involved in many different physiological aspects. [7] Cell migration plays a huge role in re-epithelialization of the skin and so the study of cell migration can provide advancements in understanding non-healing wounds. [7]
Therefore, a method for the detection of the insert would be useful for making this procedure less time- and labor-intensive. One of the early methods developed for the detection of insert is blue–white screening which allows for identification of successful products of cloning reactions through the colour of the bacterial colony. The method ...
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 ]
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 ...
Polyhistidine-tagging can be used to detect protein-protein interactions in the same way as a pull-down assay. Polyhistidine tagging has several advantages over other tags commonly used for pull-down assays, including its small size, few naturally occurring proteins binding to the carrier matrices and the increased stability of the carrier ...
The single cell gel electrophoresis assay (SCGE, also known as comet assay) is an uncomplicated and sensitive technique for the detection of DNA damage at the level of the individual eukaryotic cell. It was first developed by Östling & Johansson in 1984 and later modified by Singh et al. in 1988. [ 1 ]
Matrigel is the trade name for the solubilized basement membrane matrix secreted by Engelbreth-Holm-Swarm (EHS) mouse sarcoma cells produced by Corning Life Sciences. . Matrigel resembles the laminin/collagen IV-rich basement membrane extracellular environment found in many tissues and is used by cell biologists as a substrate (basement membrane matrix) for culturi
