Mesenchymal Stem Cell Purification from the Articular Cartilage Cell Culture
Objective Articular cartilage as an avascular skeletal tissue possesses limited capacity to heal. On the other hand, it is believed that the regeneration capacity of each tissue is largely related to its stem cell contents. Little is known about the presence of mesenchymal stem cells in articular cartilage tissue. This subject is investigated in the present study. Materials and Methods Artic...
متن کاملMolecular Characterization of Spontaneous Mesenchymal Stem Cell Transformation
BACKGROUND We previously reported the in vitro spontaneous transformation of human mesenchymal stem cells (MSC) generating a population with tumorigenic potential, that we termed transformed mesenchymal cells (TMC). METHODOLOGY/PRINCIPAL FINDINGS Here we have characterized the molecular changes associated with TMC generation. Using microarrays techniques we identified a set of altered pathway...
متن کاملSarcoma derived from cultured mesenchymal stem cells.
To study the biodistribution of MSCs, we labeled adult murine C57BL/6 MSCs with firefly luciferase and DsRed2 fluorescent protein using nonviral Sleeping Beauty transposons and coinfused labeled MSCs with bone marrow into irradiated allogeneic recipients. Using in vivo whole-body imaging, luciferase signals were shown to be increased between weeks 3 and 12. Unexpectedly, some mice with the high...
متن کاملA review of Biology and clinical use of Mesenchymal stem cell: an immune -modulator progenitor cell
Human mesenchymal stem cells (hMSCs), which also called mesenchymal stromal cells, are multipotent stem cell. Human MSCs typically are positive for the surface markers CD44, CD73, CD90, CD105, CD106, and also negative for hematopoietic markers CD34 and CD45.These cells can be isolated from postnatal bone marrow, adipose tissue, placenta, and scalp tissue, as well as from various fetal tissues. ...
متن کاملMesenchymal Stem Cells and the Origin of Ewing's Sarcoma
The origin of Ewing's sarcoma is a subject of much debate. Once thought to be derived from primitive neuroectodermal cells, many now believe it to arise from a mesenchymal stem cell (MSC). Expression of the EWS-FLI1 fusion gene in MSCs changes cell morphology to resemble Ewing's sarcoma and induces expression of neuroectodermal markers. In murine cells, transformation to sarcomas can occur. In ...
