Three-dimensional cultures modeling premalignant progression of human breast epithelial cells: role of cysteine cathepsins.

abstract：:Plasma prekallikrein (PPK) is synthesised in hepatocytes and secreted into the blood, where it participates in the surface-dependent activation of blood coagulation, fibrinolysis, kinin generation and inflammation. Recently we demonstrated by quantitative RT-PCR that the human PPK gene is transcribed not only in the l...
