Journal ArticleDOI
Different populations and sources of human mesenchymal stem cells (MSC): A comparison of adult and neonatal tissue-derived MSC
TL;DR: MSC derived from different adult and neonatal tissues are compared with respect to their cell biological properties, surface marker expression and proliferative capacities and several MSC functions including in vitro and in vivo differentiation capacities within a variety of lineages and immune-modulatory properties are highlighted.
Journal ArticleDOI
Ionizing radiation induces expression and binding activity of the nuclear factor kappa B.
TL;DR: The finding that induction of NF-kappa B binding to DNA occurs in the presence of cycloheximide indicates that ionizing radiation activates preexisting NF- kappa B protein, suggesting that ionized radiation induces transduction pathways which include cytoplasmic signaling events.
Journal ArticleDOI
Interaction of tumor cells with the microenvironment.
TL;DR: This mini-review will focus on issues that were recently raised by two review articles in CCS that essentially control most aspects of tumorigenesis such as epithelial-mesenchymal-transition, migration, invasion and chemotherapeutic drug resistance.
Journal ArticleDOI
Poly-ADP ribose polymerase activates nuclear proteasome to degrade oxidatively damaged histones
TL;DR: The poly-ADP ribosylation-mediated activated nuclear 20S proteasome is able to remove oxidatively damaged histones more efficiently and therefore is proposed as an oxidant-stimulatable defense or repair system of the nucleus in K562 leukemia cells.
Journal ArticleDOI
Effects of hypoxic culture conditions on umbilical cord-derived human mesenchymal stem cells
TL;DR: A significantly enhanced glucose consumption and a corresponding lactate production could be observed in the Hypoxic MSC cultures suggesting an altered metabolism of these human stem cells within the hypoxic environment.
