Single-Cell RT-PCR cDNA Subtraction
A major problem in trying to understand complex developmental processes is heterogeneity at both the cellular and molecular levels. At the cellular level, it is often difficult to identify cells that are undergoing developmental changes and establish the stage of differentiation they have reached. At the molecular level, there is then a problem in establishing which the many thousands of expressed genes are playing a role in regulating development. Several approaches for identifying expressed candidate developmental regulatory genes are based on comparing the mRNA expression patterns in cells before and after developmental transition points. Differential screening of cDNA libraries with labeled total cDNA probes from contrasting cell samples (1) provides a simple means of identifying genes that are expressed at high levels in one of the samples. The cDNA subtraction protocols (2,3) increased the sensitivity of this type of approach by removing sequences expressed in...
