Figure 1: CSF-1 decreases MMP2 activity in EECs. A, MMP-2 expression was examined by real-time RT-PCR in EECs and ESCs treated with CSF- 1(10 ng/mL). RNA expression was normalized to Actin RNA. B, MMP-2 activity was determined by zymography gel electrophoresis in CSF-1 treated EECs and ESC. C, A representative zymograph is shown for EECs. Digested bands are indicated by arrow |
