Matrix Metalloproteinase 9 Secreted by Hypoxia Cardiac Fibroblasts Triggers Cardiac Stem Cell Migration In Vitro

Figure 5

Protein levels of the four migration related factors whose mRNA level was also upregulated. The protein levels of those factors that were upregulated in mRNA level under hypoxia were also increased and peaked at 24 h as shown in (a) (VEGF), (b) (TNF-α), (c) (MMP-9), and (d) (MMP-2). Results are shown as the mean ± SD values. Experiments were repeated three times. indicates indicates compared to the 0 h group. indicates indicates compared to the 0 h group. # indicates compared to the 24 h group. ## indicates compared to the 24 h group.
