Fig. 2.

Highly expressed miRNA families in purified mouse spermatogenic cells. Cells were purified using different techniques (gr., gradient; HS, hyposmotic shock; SE, somatic elimination; STA-PUT, a velocity sedimentation technique for separation) or markers [SSEA (FUT4); OCT4 (POU5F1)]. miRNA families (far left) are referenced by the first well-known member of each family. Gray shaded bars indicate that a miRNA family is among the top ten most highly expressed families in at least one study and in at least one of the indicated germline cell types. The relevant references are indicated by the letters a-g; see key in bottom right. The average rank expression is shown (bold numbers) for those miRNAs for which the average rank expression across multiple studies was within the top ten.
