We describe novel ex vivo method for elimination of tumor cells from cell suspension, Laser Activated Nanothermolysis and propose this method for purging of bone marrow and blood transplants. K562 and human lympholeukemia cells were eliminated in experiments by laser-induced micro-bubbles that emerge inside individual target cells around selectively formed… (More)
The main goal of this investigation was to evaluate the abnormal T-cell immunity in cleanup workers who took part in the cleanup after the Chernobyl accident in 1986. Peripheral blood mononuclear cells (MNCs) of apparently healthy cleanup workers (n = 134) were used to analyze the phenotype and proliferative response to mitogens in vitro. Evaluation of the… (More)
We describe here the capacity of human recombinant interleukin-1-beta (IL-1beta), interferon-gamma (INF-gamma), interferon-alpha (INF-alpha), tumor necrosis factor-alpha (INF-alpha), interleukin-6 (IL-6) and interleukin-2 (IL-2) to modulate phagocytosis and bacterial killing by human neutrophils. IL-1beta, INF-gamma and TNF-alpha enhance phagocytosis of… (More)
The main directions in gene modification of human mesenchymal stem cells and the most widespread methods of transgene delivery, mainly for mesenchymal stem cells derived from bone marrow, are reviewed. The results obtained by different methods of transfection and the main types of recombinant viruses are discussed.
Expression of transgenes in neurons and stromal/mesenchymal stem cells (MSC) can greatly enhance their therapeutic potential. In transfection experiments, we studied properties of linear and branched (dendrimers) polycations as transgene delivery vehicles. Linear polyethyleneimine transfected neurons, but was ineffective in MSC. Polyamidoamine dendrimers… (More)
Genetic engineering of stem cells and their derivatives has the potential to enhance their regenerative capabilities. Here, dendrimer- and lipofection-based approaches were used for non-viral neurotrophin-3 (NT-3) over-expression in Schwann cells differentiated from skin precursors (SKP-SCs). A variety of dendrimers were first tested for transfection… (More)
Conditions for culturing and differentiation of human umbilical blood mononuclear cells in vitro were studied. The growth of mesenchymal stem cells was attained in 31 of 54 (57.4%) umbilical blood samples and morphological and immunophenotypical authenticity of these cells was confirmed. Stimulatory effects of 20% AB(IV) human serum and transforming growth… (More)
Human bone marrow MSC cultured in neurogenic medium containing EGF and FGFb demonstrated alteration of the phenotype and expression of neuronal precursor/early neuron markers nestin and NSE. Signals of expression of neuronal and oligodendroglial markers MAP-2, dm-20, and MBP were detected after prolongation of incubation in neurogenic medium to 2 weeks.… (More)
We compared the efficiency of transduction with lentivectors based on HIV-1 and adeno-associated viruses serotype 2 and stability of transgene expression in human mesenchymal bone marrow stem cells.
Research concerning new targeting delivery systems for pharmacologically active molecules and genetic material is of great importance. The aim of the present study was to investigate the potential of fourth generation (P4) cationic phosphorus-containing dendrimers to bind fluorescent probe 8-anilino-1-naphthalenesulfonate (ANS), anti-neoplastic drug… (More)
