Figure 2 (A) With the recombinant mouse standard reference, a band of the expected 20 kDa was obtained. (B) When the difference between cancerous lung tissue and paraneoplastic lung tissue was compared, the same bands of about 47 and 60 kDa were gained as from endometrium. Ab = antibody.

Figure 3 The difference in GREM1 protein expression between endometriotic and nonendometriotic eutopic endometria. EM = endometriosis; Ab = antibody. The difference is statistically significant, P<.05.

Figure 4 Standard curve with mouse recombinant standard reference of GREM1 used to measure the concentration of GREM1 in peripheral serum. Fertility and Sterility 2009 91, 350-358DOI: (10.1016/j.fertnstert.2007.12.007) Copyright © 2009 American Society for Reproductive Medicine Terms and Conditions
Figure 5 Serum concentration of GREM1 by menstrual phase. P = proliferative phase; S = secretory phase; EM = endometriosis. ∗Statistically significant difference between the two groups, P=.037; the differences in comparisons of other sample groups did not reach statistical significance.
