Tracking transplanted stem cells using magnetic resonance imaging (MRI) could offer biologic insight into homing and engraftment. Ultrasmall dextran-coated iron oxide particles have previously been developed for uptake into cells to allow MRI tracking. We describe a new application of

Crystals from commercial samples of sodium cacodylate trihydrate, NaO2As(CH3)2 x 3 H2O, were analyzed by single-crystal X-ray diffraction and two phases were identified, viz. penta-mu-aqua-disodium(I) bis(dimethylarsenate), {[Na2(H2O)5](C2H6AsO2)2}n, (I), and di-mu-aqua-bis[triaquasodium(I)] bis(dimethylarsenate), [Na2(H2O)8](C2H6AsO2)2, (II). Both (I) and (II) form layered structures

Enhanced expression of tenascin-C (TN-C) at the invasive edges of glioblastoma multiforme in close association with vascular sprouts, suggests a role for TN-C in microvascular cell migration. To test this hypothesis, we studied the migration of endothelial cells in vitro.

While the subcellular organisation of mitochondria is likely to influence many aspects of cell physiology, its molecular control is poorly understood. Here, we have investigated the role of the retrograde motor protein complex, dynein-dynactin, in mitochondrial localisation and morphology. Disruption
