Figure 2: Migration of Human fetal MSC is independent of MMP1. (A) Expression of Pro-MMP1 in 100 μg of conditioned medium harvested from various MSC. Data shown is the average of duplicate wells from representative experiments. (B) MMP1 activity was quantitated in conditioned medium harvested from various MSC. Bar graph represents active MMP1 normalized to MSC-1. Data shown are averages of duplicate wells from representative experiments.
