(A) Representative secretion pattern of proMMP-2 (72 kD) and proMMP-9 (92 kD) in 6–8 w, 9–12 w trophoblasts and in JAR cells without treatment as examined with zymography. (B) Bar graph describing the relative percentage of gelatinases secretion, representing mean ± SEM from 5 independent experiments. Black bars represents proMMP-2 and white bars represent proMMP-9, *P < 0.05.
