Extraembryonic tissues, in particular, umbilical cord stroma are promising sources of multipotent mesenchymal stromal cells for regenerative medicine. In recent years, methods for isolation of mesenchymal stromal cells from different compartments of the umbilical cords based on enzymatic disaggregation of the tissue or on tissue explants have been proposed. Here we propose a protocol of isolation of multipotent mesenchymal stromal cells from the whole umbilical cord that combines the advantages of each approach and ensures sufficient cell yield for further experimental and clinical applications. A combination of short-term incubation of tissue fragments on cold collagenase solution followed by their culturing in the form of explants significantly increased the yield of cells with high proliferative activity, typical pluripotent mesenchymal stromal cell phenotype, and preserved differentiation capacity.
