miR-29a is dominant in hippocampus and enriched in astrocytes. A. Relative levels of miR-29a, b, and c in normal rat hippocampus. N=4–6/group. B. Relative miR-29a levels in primary cultures of cortical neurons and astrocytes from 3 to 30 days in vitro, and postnatal day 3 to 60 brain cortex. All experiments were performed 3 times in triplicate. All values were normalized to neuronal miR-29a level at 3 days.
