neoplastic bone marrow niche: hematopoietic and mesenchymal stem cells
the neoplastic niche comprises complex interactions between multiple cell types and molecules requiring cell-cell signaling as well as local secretion. these niches are important for both the maintenance of cancer stem cells and the induction of neoplastic cells survival and proliferation. each niche contains a population of tumor stem cells supported by a closely associated vascular bed compri...
متن کاملBone marrow CD169+ macrophages promote the retention of hematopoietic stem and progenitor cells in the mesenchymal stem cell niche
Hematopoietic stem cells (HSCs) reside in specialized bone marrow (BM) niches regulated by the sympathetic nervous system (SNS). Here, we have examined whether mononuclear phagocytes modulate the HSC niche. We defined three populations of BM mononuclear phagocytes that include Gr-1(hi) monocytes (MOs), Gr-1(lo) MOs, and macrophages (MΦ) based on differential expression of Gr-1, CD115, F4/80, an...
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 کاملEndothelial Progenitor Cell Fraction Contained in Bone Marrow-Derived Mesenchymal Stem Cell Populations Impairs Osteogenic Differentiation
In bone tissue engineering (TE) endothelial cell-osteoblast cocultures are known to induce synergies of cell differentiation and activity. Bone marrow mononucleated cells (BMCs) are a rich source of mesenchymal stem cells (MSCs) able to develop an osteogenic phenotype. Endothelial progenitor cells (EPCs) are also present within BMC. In this study we investigate the effect of EPCs present in the...
