Figure 4

Additional Northern blots showing miRNA expression in various tissues and cell types. Shown are Northern blot data for the indicated miRNAs in different unstimulated cell types. Asterisks indicate bands of the size of pre-miRNA (60-70 nucleotides), which were detected in Northern blot for only a subset of the miRNAs analyzed. There was a good correlation overall between Northern blot data and expression data from the arrays (see heat map in Figure 5 and Table 2), with some exceptions, as discussed in the text. BMMC, bone marrow-derived mast cells; DN T, double-negative thymocyte.
