Figure 8. Expression of human MMP genes. (A) Heatmap of human MMP gene expression in 11 tissues. (B) Longitudinal expression of human MMPs in testis (not normalized). (C) Longitudinal expression of human MMPs in testis (normalized). (D) Longitudinal expression of human MMPs in ovary (not normalized). (E) Longitudinal expression of human MMPs in ovary (normalized). The MMP genes are clustered based on expression patterns.
