It is demonstrated that the output optical signal of MTT test is directly proportional to the number of viable cells in the primary culture of mesenchymal cells (skin fibroblasts and mesenchymal stem cells from the bone marrow, placenta, and umbilical cord). The slope of the best curve in coordinates “cell number - optical signal” reflecting specifi c productivity of MTT-formazan characterizes mean dehydrogenase activity of cells and their physiological activity. It was found that in vitro dehydrogenase activity of primary cultures of mesenchymal cells increased during the first 3-5 passages and then tended to decrease. The variant of MTT method presented here can be used for standardization of cell materials.
