Abstract:
PROBLEM TO BE SOLVED: To provide a process and composition for maintaining a human hematopoietic stem cell to reduce or eliminate differentiation of a human mesenchymal stem cell into a committed lineage. SOLUTION: The process is provided for maintaining the human hematopoietic stem cell in co-culture with the human mesenchymal stem cell such that the CD34+/Thy1+ phenotype for the human hematopoietic stem cell is maintained. Furthermore, the composition therefor is provided. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
The invention relates to the induction of hematopoietic stem cells to differentiate into osteoclasts by culturing hematopoietic stem cells with human mesenchymal stem cells, and, in a preferred embodiment, using no exogenous cytokines. Differentiation of the mesenchymal stem cells into osteoblasts inhibited the differentiation of hematopoietic stem cells into osteoclasts. In addition, hematopoietic stem cells can be genetically engineered to carry genes of interest particularly for the expression of physiologically active proteins. In the presence of mesenchymal stem cells, the transduced cells carry the new genetic material and express gene products that can be used to modulate bone resorption.
Abstract:
The present invention is directed to human mesenchymal stem cells isolated from a tissue specimen, such as marrow cells, and to the method of co-culturing isolated mesenchymal stem cells and/or mesenchymal stem cell-derived adipocytes with hematopoietic progenitor cells such that the hematopoietic stem cells retain their phenotype.
Abstract:
A human mesenchymal stem cell (hMSC) cDNAs and putative polypeptides derived from Open Reading Frames contained therein are disclosed. Also disclosed are methods for utilizing the polynucleotides and polypeptides, including use as reagents for chromosomal mapping and identification, DNA fingerprinting and the possible role played by genetic mutations in the disease process, and for the generation of polyclonal and/or monoclonal antibodies specific for said polypeptides.
