Chemotaxis of tumour cells and stromal cells in the surrounding microenvironment is an essential component of tumour… Expand Mathematical modelling of chemotaxis (the movement of biological cells or organisms in response to chemical gradients) has… Expand Bacteria must be able to respond to a changing environment, and one way to respond is to move. The transduction of sensory… Expand Integral feedback control is a basic engineering strategy for ensuring that the output of a system robustly tracks its desired… Expand Networks of interacting proteins orchestrate the responses of living cells to a variety of external stimuli, but how sensitive is… Expand We have used Escherichia coli as a model system to investigate the initiation of biofilm formation. Here, we demonstrate that E… Expand SUMMARY: Chemotaxis of a bacterium such as Escherichia coli is assayed by measuring the number of organisms attracted into a… Expand A "temporal gradient apparatus" has been developed that allows the motility of bacteria to be studied after they have been… Expand Abstract The chemotactic response of unicellular microscopic organisms is viewed as analogous to Brownian motion. Local… Expand Motile Escherichia coli placed at one end of a capillary tube containing an energy source and oxygen migrate out into the tube in… Expand
