Figure 4From: Expression and importance of matrix metalloproteinase 2 and 9 (MMP-2 and -9) in human trophoblast invasionSecretion of proMMP-2 and proMMP-9 after 48 hours incubation of JAR cells, 1st trimester trophoblast cells 6–8 week or 1st trimester trophoblast cells 9–12 week in medium in absence or presence of 10 μM Forskolin. (A) Representative zymography gels. (B) Bar graph, representing mean ± SEM from 10 independent experiments detecting proMMP-2 (72 kD). (C) Bar graph, representing mean ± SEM from 10 independent experiments detecting proMMP-9 (92 kD). White bars represent control medium of cells without treatment. Black bars represent medium from cells with forskolin treatment. *P < 0.05 vs. control.Back to article page
