Content of IL-10 and CD4+CD210+ cells in mice with adjuvant arthritis before and after treatment with cryopreserved placental cells.

We analyzed the serum level of IL-10, blood content of CD4+СD210+ cells, and expression of IL-10 receptors in adjuvant arthritis before and after treatment with native and cryopreserved placental cells. In animals with experimental adjuvant arthritis, a negative correlation was found between the index of arthritis and IL-10 concentration (r=-0.7; p=0.

The use of nanocomposite coatings with various physicochemical properties in tissue engineering.

We studied the effect of nanocomposite coatings with various physicochemical properties on the structural and functional properties (adhesion potential, phenotype, gene expression) of mesenchymal stem cells. Of all tested nanocoatings (Al2O3, ZrO2, Ta2O5), oxide coating Al2O3 enriched in vitro monolayer bone marrow cell culture with cells carrying mesenchymal stem cells phenotype markers and stimulated expression of ido gene, which can confer new therapeutic potencies to these cells and extend their application in clinical practice.

[Effect of PHA on lymphocyte respiratory activity in mice].

A study of the intensity of oxygen consumption by mice lymphocytes at different stages of cultivation with PHA showed a pronounced increase of the respiratory activity beginning from the 14th hour. Maximum values of oxygen consumption by stimulated cells were observed at the 16th and 30th hours of cultivation (before the beginning of blastogenesis and before the maximum uptake of H3-thymidine, respectively.

[Conservation of bone marrow CFUc in different phases of the cell cycle during cryopreservation].

The effect of low temperature (-196 degrees C) preservation on the recovery of colon-forming units (CFUs) of bone marrow at different phases of the cell cycle before cryopreservation is dealt with. The intact bone marrow "enriched" with CFUs in S phase of the cell cycle and the bone marrow without colony-forming units in S phase were exposed to cryopreservation. After cryopreservation of the bone marrow enriched with CFUs in S phase and th bone marrow without colony-forming units in S phase the number of CFUs decreases by the same value as in the cryopreserved bone marrow obtained from intact mice.
