The invention relates to the field of cell biology. In detail it relates to the obtainment of mesenchymal stem cells from human tissue. This invention might be applicable in healing within the frame of the treatment of several diseases. Due to the invention it will be possible to obtain mesenchymal stem cells from human tissue with high homogeneity of the cell suspension, since the used method for obtaining mesenchymal stem cells from human tissue comprises the crushing and enzymatical treatment of the tissue with collagenase solution in Eagle medium in the Dulbecco modification, removal of erythrocytes by the aid of the lysis solution and subsequent filtration of the prepared suspension; as human tissue fat tissue or decidual or amniotic placenta membrane or chorion placenta stroma is used, whereas the filtration is performed sequentially by the use of filters comprising a pore size of 100 μm and 10 μm. In the enzymatical treatment of the fat tissue, of the decidual or amniotic placenta membrane collagenase of the type I is used, and in the enzymatical treatment of the chorion placenta stroma collagenase of the type IV is used. |
