Multipotent adult stem cells (MAPC) MAPCs can be derived by culturing bone marrow mononuclear cells, after depleting CD45+ and GlyA+ cells, with FCS, EGF, and PDGF-BB (h). MAPCs are very rare cells that are present within MSC cultures from postnatal bone marrow (m,[r]

The cancer stem cells (CSCs), a small subpopulation of cells in tumor are responsible for the tumor initiation, growth, recurrence and metastasis of cancer, as well as resistance of cancers to drugs or radiotherapy. CSCs are an important target for the development of novel strategies in cancer treat[r]

production during development, but for most of human life it is located in the bone marrow. Within the bone marrow, at least two niche sites have been proposed: on trabecular bone surfaces and in the perivascular space. Stem cells may be found in both places by histologic[r]

In the present study, we demonstrate that S100A4 is up-regulated in MB49 bladder cancer stem cells (MCSCs). Additionally, overexpression of S100A4 en- hances the proliferation capacity of MCSCs in vitro, and also upregulates inhibitor of nuclear factor kappa B NF[r]

Elucidating the precise properties of cancer stem cells (CSCs) is indispensable for the development of effective therapies against tumors, because CSCs are key drivers of tumor development, metastasis and relapse.
