Messenger RNA Differential Display: An Unbiased Tool to Uncover Alterations in Gene Expression Underlying Biological Processes

The vast majority of somatic cells possess the same complement of genes. What makes one cell different from another is the subset of genes that each expresses. Further, the regulated expression of different sets of genes within a cell largely controls phenomena such as cell development, differentiation, adaptive responses to environmental signals (including drug treatment), and even certain types of cell death.
