Figure 7From: The role of a new CD44st in increasing the invasion capability of the human breast cancer cell line MCF-7 Secretion of HA inducting MMP-2 and MMP-9 protein. Cells treated with HA were incubated in serum free medium with or without HA (100 μg/ml) for 24 h. The secretion of HA inducting MMP-2 and MMP-9 was detected by zymography. Normal human blood was used as a positive control to identify MMP-9 and MMP-2 on gelatin zymograms.Back to article page
