Precancerous Stem Cells Can Serve As Tumor Vasculogenic Progenitors
Tumor neo-vascularization is critical for tumor growth, invasion and metastasis, which has been considered to be mediated by a mechanism of angiogenesis. However, histopathological studies have suggested that tumor cells might be the progenitor for tumor vasculature. Recently, we have reported that the precancerous stem cells (pCSCs) representing the early stage of developing cancer stem cells ...
متن کاملParent stem cells can serve as niches for their own daughter cells
Stem cells integrate inputs from multiple sources. Stem cell niches provide signals that promote stem cell maintenance1-2, while differentiated daughter cells are known to provide feedback signals to regulate stem cell replication and differentiation3-6. Recently, stem cells have been shown to regulate themselves using an autocrine mechanism7. The existence of a “stem cell niche” was first post...
متن کاملMesenchymal Stem Cells as a Feeder Layer Can Prevent Apoptosis of Expanded Hematopoietic Stem Cells Derived from Cord Blood
Umbilical cord blood (UCB) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (HSCs). Because of insufficient number of cord blood CD34+ cells, the expansion of these cells seems to be important for clinical application. Mesenchymal stromal cells (MSCs), playing an important role in HSCs maintenance, were used as feeder layer. Apo...
متن کاملStem-like ovarian cancer cells can serve as tumor vascular progenitors.
Neovascularization is required for solid tumor maintenance, progression, and metastasis. The most described contribution of cancer cells in tumor neovascularization is the secretion of factors, which attract various cell types to establish a microenvironment that promotes blood vessel formation. The cancer stem cell hypothesis suggests that tumors are composed of cells that may share the differ...
متن کاملLow-affinity nerve-growth factor receptor (P75NTR) can serve as a receptor for rabies virus.
A random-primed cDNA expression library constructed from the mRNA of neuroblastoma cells (NG108) was used to clone a specific rabies virus (RV) receptor. A soluble form of the RV glycoprotein (Gs) was utilized as a ligand to detect positive cells. We identified the murine low-affinity nerve-growth factor receptor, p75NTR. BSR cells stably expressing p75NTR were able to bind Gs and G-expressing ...
