We studied umbilical cord blood mesenchymal stem cells and compared mesenchymal stem cells derived from umbilical cord blood, adipose tissue, and skin. Umbilical cord blood mesenchymal stem cells were characterized morphologically, cytofluorometrically, and by their differentiation potential. Umbilical cord blood mesenchymal stem cells did not differ from(More)
Cell-to-cell interactions of human mesenchymal multipotent stromal cells (MMSC) and rat renal tubular cells (RTC) were explored under conditions of co-cultivation. We observed formation of different types of intercellular contacts, including so called tunneling nanotubes. These contacts were shown to be able to provide transfer of cell's contents, including(More)
UNLABELLED The goal of the present study was to maximally alleviate the negative impact of stroke by increasing the therapeutic potency of injected mesenchymal multipotent stromal cells (MMSCs). To pursue this goal, the intercellular communications of MMSCs and neuronal cells were studied in vitro. As a result of cocultivation of MMSCs and rat cortical(More)
The aim of this work was to develop a quick method for analysis of macromolecules of the extracellular matrix. Of great interest are soluble components of the extracellular matrix, in particular, carrier proteins, whose variation dynamics can characterize the studied tissue in its development, adult stage, and aging. We suggest the method of analysis of the(More)
Neural stem cells of human brain were cultured for a long time and successfully transplanted into the brain of rats exposed to acute hypoxia. Stem and committed cells, neuroblasts, and astrocytes were revealed in transplants by immunohistochemical assay. The transplants and brain tissue were not separated with a glial barrier. Human neuroblasts widely(More)
Five stable hybridomas against placental protein PAMG-1 were obtained. Monoclonal antibodies were not cross reactive with other placental proteins and human serum albumin. The content of PAMG-1 during a physiological pregnancy increased to 40 ng/ml. 23 women with repeated abortions had an increased content of PAMG-1.
Institute of Biological Medicine, Moscow The formation of the concept of a mesenchymal stem cell (MSC) is a priority of Russian biological science. A. Ya. Fridenshtein and his colleagues were the first who experimentally proved the existence of MSC. Osteogenic potential of fibroblastlike bone marrow cells of different mammalian species was demonstrated(More)
The dose-dependent alpha-fetoprotein (AFP) reactivity of different types of tumor cells and normal embryonal fibroblasts, which are capable of taking up AFP, was investigated. High doses (more than 100 micrograms/ml) of purified human AFP were shown to induce strongly dose-dependent growth inhibition of human hepatoma HepG2 cells, human lymphoblastoma MT4(More)
Generation of active oxygen forms by blood granulocytes was studied in women with a history of habitual abortions (2-3 spontaneous abortions in the first trimester, undeveloped pregnancies). The level of spontaneous luminol-dependent chemiluminescence of nonfractionated peripheral blood was increased in this patient population (study group) in comparison(More)
We, for the first time, directly compared gene expression profiles in human non-small cell lung carcinomas (NSCLCs) and in human fetal lung development. Previously reported correlations of gene expression profiles between lung cancer and lung development, deduced from matching data on mouse development and human cancer, have brought important information,(More)
