Figure 1. Breast MSCs secrete MMP1, MMP2 and MMP3. (A and B) Conditioned media was collected and concentrated from the respective MSC cultures, monolayers were lysed and samples were analyzed by SDS-PAGE. Here we show bMSC donor strains 1 and 2 as representative data. Two additional bMSC strains (including donor #3) yielded similar high levels of the respective MMPs.
