Human neural stem/progenitor cells provide a useful tool for studies of neural development and differentiation, as well as a potential means for neuroreplacement therapeutic needs in the human CNS. Stem cells isolated from developing human central nervous system of 8-12-week fetuses were transplanted to the forebrain and cerebellum of young and adult rats(More)
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.(More)
We studied the effect of systemic administration of multipotent stem cells on impaired neurological status in rats with brain injury. It was found that transplantation of multipotent mesenchymal stromal cells of the bone marrow or human neural stem and progenitor cells to rats with local brain injury promoted recovery of the brain control over locomotor(More)
Human neural stem cells (HNSCs) are used in studies of neural development and differentiation, and are regarded as an alternative source of tissue for neural transplantation in degenerative diseases. Selection and standardization of HNSC samples is an important task in research and clinical approaches. We evaluated embryonal brain matter obtained from human(More)
We describe a method of isolation of human mesenchymal stromal cells from the umbilical cord (Wharton’s jelly) and human placenta: amnion, placental villi, and trophoblast. Morphology, immunophenotypic characteristics, and differentiation potencies of isolated cells were studied. The capacity of mesenchymal stromal cells from extraembryonic tissues to(More)
We studied cell cultures isolated from the pulp of third molar germ of an adult human and from the skin of a human fetus on gestation day 10. Both cultures expressed similar repertoire of surface markers typical of multipotent mesenchymal cells (CD44, CD90, and CD105). Under in vitro conditions, dental pulp cells were more susceptible to factors inducing(More)
Umbilical cord stroma is an easily available, convenient, and promising source of multipotent mesenchymal stromal cells for regenerative medicine. Cryogenic storage of umbilical cord tissue provides more possibilities for further isolation of multipotent mesenchymal stromal cells for autologous transplantation or scientific purposes. Here we developed a(More)
We analyzed changes in cell composition of umbilical cord blood and functional activity of hematopoietic stem cells during cryogenic storage and after repeated freezing/thawing cycles. It was found that repeated freezing/thawing cycles performed according to the optimal programmable freezing protocol did not significantly affect viability and functional(More)
Cell cultures isolated from endometriosis lesions by enzymatic dissociation consisted of fibroblast-like cells expressing CD90, CD73, and CD105; cell viability in these cultures was >90%, but this parameter decreased by passage 3. Zero passage cultures contained 10-25% epithelial cells expressing cytokeratin-7, but by passage 2, the cultures became more(More)
Changes in cell composition and viability as well as the content and functional activity of hemopoietic progenitor cells were analyzed during long-term (up to 1 month at 4°C) storage of human umbilical cord blood cells. No significant quantitative changes in erythrocytes were found during this period. The total content and viability of leukocytes changed,(More)
