Current methods to promote growth of cultured neurons use two-dimensional (2D) glass or polystyrene surfaces coated with a charged molecule (e.g. poly-L-lysine (PLL)) or an isolated extracellular matrix (ECM) protein (e.g. laminin-1). However, these 2D surfaces represent a poor topological approximation of the three-dimensional (3D) architecture of the(More)
The acute effects of low concentrations of ethanol on intracellular free magnesium ions ([Mg2+]i) in cultured type-2 astrocytes were studied by digital imaging microscopy using the Mg2+ fluorescent probe, mag-fura-2. In 0-mM ethanol, the basal level of [Mg+]i was 124.7+/-2.56 microM with a heterogeneous distribution within the cells. Treatment of the cells(More)
This study was designed to examine the roles of intracellular free magnesium ion concentration ([Mg(2+)](i)) in ethanol-induced intoxication and development of tolerance in cultured canine cerebral vascular smooth muscle cells and astrocytes as well as intact rat brain. The basal, resting level of [Mg(2+)](i) in cerebrovascular cells was 732.5 +/- 82.4(More)
