title: [Stimulation of cell cultures recovery after cryopreservation by the cattle cord blood FRACTION (below 5 kDa) or Actovegin].
abstract: The capacities of the cattle cord blood low-molecular fraction (below 5 kDa) and Actovegin (the vealer blood fraction (below 5 kDa)) for recovering functions of cell cultures after cryopreservation compared. Their influence proliferation of the flozen-thawed cell cultures, certain stages of their growth, cell attachment, rate of cell spreading, and mitotic regiment has been studied. Both the cord blood low-molecular fraction and Actovegin were shown to stimulate growth of the cell cultures after cryopreservation more efficiently at the concentration of 224 μg/ml. However, despite the stimulating effect discovered, their application did not bring proliferative indices on the 1st passage after cryopreservation to the values of the native culture. The effects of the cord blood low-molecular fraction and Actovegin on the human fibroblast culture were identical by the following parameters: cell attachment, rates of cell spreading and proliferation. In culture BHK-21 clone 13/04 the efficiency of Actovegin was low, while the cord blood low-molecular fraction has a conspicuous stimulating effect on its adhesion and proliferation. The investigations carried out can serve as a basis for the development of regenerative media containing the cattle cord blood low-molecular fraction (below 5 kDa) or Actovegin as active components at the concentration of 224 μg/ml with the purpose of fast recovery of culture prolifetative properties after cryopreservation.
