Figure 2.

Gene expression profiles in the postnatal developing mouse brain. RNA fingerprints produced by specific DDRT-PCR primer combinations at four stages of brain development run in parallel. Anchored primer/arbitrary primer combinations are shown at the top for each group of RNA fingerprints and stages of development are indicated in days (1, 10, 20 and 42). Gel positions of developmentally regulated transcripts in expression category A (+), expression category B (-) and expression category C (^) are highlighted.
