[Cell composition of umbilical cord blood in complicated and uncomplicated pregnancy].

Possible influence of most frequently encountered types of pathology during pregnancy on the cell composition of umbilical cord blood was studied. These pathologies included: treated iron-deficiency anemia, essential hypertension, threatening spontaneous abortion. A number and proliferative potential of granulocyte-macrophage precursor cells of umbilical cord blood were studied by agar drop-liquid media culture method.

[Distribution of hematopoietic stem cells in the mononuclear fraction of human umbilical cord blood].

The advances in transplantation of hemopoietic stem cells (HSC) from umbilical human blood (UHB) necessitate introduction of effective methods of HSC isolation and preservation. The studies show that UHB cells remained viable even after several days of storage at room temperature. Density gradients proved effective for isolation of cell precursors from UHB.
