Inhibition of MEF growth by MMC in CM. (A) Phase contrast microscopy images of MEFs treated with 10 µg/ml MMC for 0–2.0 h in CM and observed on days 1, 3, 5 and 7. Bars = 40 μm. (B) Cell counts of inactivated MEFs in each well of 24-well plate (Student’s t test and ANOVA; **P < 0.01 versus each group of days 1, 3, 5 and 7).
