( c ) No obvious morphological changes were observed between wild-type ( Dgcr8 +/+ ) and miR-673-deficient ESCs ( d ) Quantification of Nanog and Pouf5f1 pluripotent markers upon knocking out miR-673 by CRISPR in comparison to wild-type ESCs, data show the average (n = 3)±s.e.m, (n.s.) non-significant by t-test. NIH3T3 serves as a negative control for pluripotent maker expression ( e ) Quantification of Nanog and Pouf51 expression after reintroduction of miR-673 mimics and controls for 24 or 48 hr. Data show the average (n = 3)±s.e.m. (n.s.) non-significant by t-test.
