HOT Screen - next generation of drug R&D

From linear thinking to complex models or from late failure to early success



The practice of growing human cells in vitro over the last three decades has typically used a single clonal type of cell that is modified to proliferate indefinitely outside of the body in a laboratory dish. These “transformed” cell lines, although useful for some experiments, often have little in common with the cells found in the body. Conversely, human Co-Culture cell systems are made with a mixture of primary cell types that more closely resembles actual physiological conditions. This Co-Culture containing multiple primary cell types creates a three-dimensional architecture much as they do in the body, providing a more life-like setting in which to test compounds for drug and product development.

- 
	
- Complexity is the basis of drug effects on the human immune system 
	
- Complexity in vitro, handled properly, is an enormous chance and definitely not a problem 
	
- Complexity should therefore never be ignored in drug R&D 
	
- Complex organotypic model improve drug activity profiling substantially 
	
- HOT culture models provide access to physiological complexity even at very early stages of drug discovery in vitro
