Escherichia coli causes sepsis in neonates who ingest the bacteria around the time of birth. The process involved in E. coli’s ability to travel from the enteric tract to the bloodstream is poorly understood. This in vitro model assesses the ability of E. coli strains to travel through the intestinal epithelial cells.

Many upregulated genes stimulate tumor cell migration and invasion, leading to poor prognosis. Determining which genes regulate tumor cell migration and invasion is critical. This protocol presents a method for investigating the effects of the increased expression of a gene on the migration and invasion of tumor cells in real time.
