title: [Dynamics of matrix metalloproteinases activity of primary murine embryonic fibroblasts during cultivation].
abstract: Embryonic cells regulate the expression of matrix metalloproteinases (MMP) providing remodulation of extracellular matrix, which in turn provides the changes in cell adhesion and migration during the cell development and differentiation. In present work we studied the changes of gelatinases (MMP-2 and MMP-9) and collagenases (MMP-1 and MMP-8) activities in the process of cultivating the primary murine embryonic fibroblasts (MEF). Cultivation was continued for 6 passages, after that the culture died in time. According to gelatin and collagen zymography results, drastic changes of all MMPs activities occurred during the third passage of cell cultivation. The MMP-1 and MMP-9 activity appears in the middle of cultivation and then disappeared at the end. The most important event MEF cultivation is appearance and subsequent reservation of collagenase MMP-8 and active form of gelatinase MMP-2.
