Figure 3From: Type V collagen induces apoptosis of 8701-BC breast cancer cells and enhances m-calpain expressionExtent of DNA fragmentation in 8701-BC cells after 48 and 72 h from seeding onto either type IV or type V collagen substrates. Vertical bars indicate the s.e.m. of quadruplicate experiments. *p < 0.05 (type V versus type IV collagen)Back to article page
