An ex vivo cornea infection model
In vitro screening and testing of drugs and devices is necessary, but in vitro conditions differ greatly from those found in vivo. These differences can lead to false promises of efficacy, or can hide problems of tissue compatibility. Models with ex vivo tissues can be highly valuable bridges which...
