The change folds from quantification of gene expression on morula stage mouse embryos after microinjection of 1.5 fmol LIF-siRNA at mouse 2PN stage (N = 3) and supplemented with 50 ng/ml LIF protein, compared with the scrambled-siRNA treated embryos.

The gene expressions were expressed as mean from 3 repeats and the bars are designed as standard deviations.
